Computing Fundamentals at U-M

The University of Michigan has a special and unique computing environment. U-M staff, faculty, and students have access to some of the finest academic computing resources in the nation. This part of the workshop is an introduction to the special features of our computing environment. It is our intention that this workshop will help you become more familiar with the computing services available to you here at U-M. As you become more familiar with the rich source of computing resources available at the University, you will be better able to make a more informed choice about which programs can be of most help to you in your specific work or study situation.

Additional aids besides this workshop are available to help you learn to use the U-M computing resources most effectively. These include additional workshops, a vast array of computing documentation, and information stored online. These aids are listed in this workshop handout. We will refer to many of them throughout the workshop. Many of the computing services we will be exploring—including this workshop—are provided by the University’s Information Technology Division (ITD).

**Service will be demonstrated in the workshop.*Indicates documentation that is included in the workshop materials.

Using the U-M Computer Networks To use many of the computing resources available at U-M, you must be able to communicate with the computers where these services are stored. This frequently requires connecting to a network. A network is two or more computers connected together with printers, and possibly other appropriate devices, so that they can all communicate with each other. Many, if not most of the members of the U-M community who use computers are part of one or more networks.

Your network may be a LAN (Local Area Network), operated by your department. The campus backbone network, which is made of fiber optic cable, connects these LANs together into a network of networks enabling the entire U-M community, including the Flint and Dearborn campuses to communicate and work together. We should point out that the computing, telephone, and video connections between the three campuses do not travel on cable. Instead, they are transmitted electronically between microwave towers on each of the three campuses.

ITD is responsible for creating and maintaining this entire U-M communications network and for connecting the University community to the outside world. While the ITD telecommunications unit handles internal phone calls, University phone calls to places outside the U-M are transferred to the common telecommunication carriers.

ITD is also responsible for providing the computing connections between the U-M and the computing world outside the University, including connections to MichNet, and the National Science Foundation Network (NSFnet)—the principal academic and research backbone for the US and a major part of the worldwide Internet.

The University of Michigan’s computing environment is generally decentralized and distributed. In other words, at U-M we don’t rely on a single centralized computer system, but rather on many networks serving various parts of the U-M that are joined together. Authority over the various parts of the campus-wide computing network is diffused among the units which own each part.Two of the very large units of the University have their own extensive fiber networks. These include CAEN the Computer-Aided Engineering Network, which serves the many buildings that

comprise the College of Engineering on the U-M North Campus. The Medical Center Information Technology (MCIT) organization has its own fiber network which connects the entire Medical Center together. The CAEN and MCIT networks are interconnected with the ITD-maintained campus-wide computing backbone network which connects most of U-M LANs together.

MichNet and the World-wide InternetWhile many of the computing resources we choose to use are located on the U-M campus, some of these require that we connect to the computing world beyond U-M. Consequently, its important for us to have some understanding of the networks that exist beyond the University.

The U-M computing network is connected to and part of the Michigan regional network called MichNet. MichNet is operated by Merit, a consortium of Michigan universities which is based on the University campus and has a close relationship with the U-M. MichNet connects many networks around the state, including those at universities and colleges, K-12 schools and school districts, hospitals, private corporations, research institutions, libraries, and many other organizations.

MichNet is one part of the international Internet, that vast collection of networks around the world that are interconnected. The Internet is sometimes called the “information superhighway.” Since our campus networks are part of MichNet, they are also part of the Internet. Members of



the University community with computer connectivity thus have access to the extensive resources available on the Internet.

The InternetThe Internet is a worldwide network of about half a million computers belonging to educational and research organizations, the military, corporations, and many other types of organizations. The Internet, or information superhighway, is not a destination but the means by which you get to your destination. Mail and files move across the “net” from computer to computer until they reach their final destination. You can send personal mail and access many different services.

The Internet is free to users, the costs being paid by participating educational and research organizations, the military, the government, and the other organizations and corporations who use it. U-M is one of the original members of Merit and contributes to the support of MichNet—the Michigan part of the Internet.)

The Internet has been around for many years, but it only recently became the “information superhighway” of the general population. Previously the software that accessed remote computers was complex and navigating tools were not developed.

A few years ago the University of Minnesota developed Gopher, a software program which makes it relatively easy to access information stored on the Internet. We will talk about and demonstrate the U-M GOpherBLUE server later in this workshop.

Client/Server ProgramsIn order to access services stored on U-M servers and elsewhere on the Internet, a user often needs one or more software programs loaded on their computer. These programs make it possible for the computer to make the connection(s). In these situations, your computer is the “client” machine, receiving services from the “server” computer. The software you need to accomplish this is called “client” programs. Information on how and where to get these programs for the various services is listed in this handout.

**The U-M GOpherBLUE Server (Note: The GOpherBLUE server is scheduled to be phased out over the 1996-97 year. We include it in this workshop until it is truly gone, because it contains much useful information and is easy to use. A recent ITD customer survey indicates that GOpherBLUE is a very popular service at U-M. When Gopher is phased out, the information currently stored there will be moved to the World-Wide Web.)

Gopher uses menus and allows easy selection of items. The U-M’s GOpherBLUE information server is accessible to U-M faculty, staff, and students on the Internet, and through the campus AppleTalk network. Some of the information on GOpherBLUE, U-M open positions and Non-Credit Campus Computing Workshops, is stored on computers on the U-M campus. Where the information is stored is not of concern to the GOpherBLUE user. Once an item is selected from a menu, GOpherBLUE makes the appropriate connection and presents the information on the user’s screen.

U-M information available on the U-M GOpherBLUE includes: news and weather, the X.500 directory, historic documents and speeches, U-M Library information, and Computing on Campus. The Computing on Campus information includes computer sales information, software available at U-M, and ITD computer documentation. Complete copies of InfoTech Digest, an ITD-produced periodical which keeps U-M users up-to-date on the latest computing changes and



services are there. A list of ITD products and services, computer use policies information, and much, much more is available on the U-M GOpherBLUE server.

The World-Wide Web (WWW)Now, in addition to Gopher, we use the World-Wide Web (WWW or “the Web”). The World-Wide Web is a global web of computer-accessible information, organized into “pages.” There are over 20 million “home pages” on the Web, set up by people and organizations, including U-M schools and departments, which provide excellent sources of information.

Each Web page contains links—words, pictures, sounds, and even video—that you click on to move to other pages, often of related information. This clicking on the various links allows you to “surf the Web.” When you use your mouse to click on highlighted words, pictures and icons, the related files which may be located anywhere on the Internet, are presented on your screen. The advantage of making information available on the Web is that it can be more easily updated and distributed than information in hard copy format.

The interconnected computers and computer networks, including MichNet and the U-M campus network that make up the Internet, can communicate with each other because they have agreed to a common language or set of protocols called TCP/IP (Transmission Control Protocol/Internet Protocol.) Although some Internet resources are available without TCP/IP, (and we will mention these in this workshop), if you want to fully connect your computer to the Internet, you need software that uses or supports TCP/IP.

The ITD Web Page viewed in Netscape

** Using Netscape to Access the Internet Currently, at U-M, the Netscape Navigator (usually called “Netscape”) software program is the most popular method for “browsing” the Web for information stored on the Internet. Lynx, a text-only browser, available from the ITD Login Service, is also available.

There are versions of Netscape that run on Macintosh, Windows 3.1, Windows 95, and Windows NT, as well as on Unix computers. Netscape is available at all U-M Campus Computing Sites and in the U-M Libraries. It is also available on the U-M network.

This software is licensed to the University for use by all U-M students, staff and faculty members. There is no fee to the individual user as the University has paid one site license fee to enable everyone to use it.

Minimum system requirements:A direct connection to the Internet, through the U-M backbone network, or a dial-up PPP connection with a 14.4 bps or faster modem is necessary to use this software.

Macintosh minimum system requirements are at least a Mac II computer with a minimum of 4 MB memory (RAM); 8MB of memory is preferable. Macintosh Operating System version 7.0 or later is necessary along with MacTCP. MacTCP version 2.0.2 will work; version 2.0.6 is recommended.

The minimum computer for Windows users is a 386SX with a minimum of 4 MB memory (RAM). A 486/33 computer with 8 MB memory is recommended. More powerful computers are also acceptable. Also necessary to run Netscape is Windows 3.1 running in enhanced mode and WinSock. WinSock is available as a LAN WorkPlace for Windows patch and is included in PC/TCP software. (A patch is a small program supplied by the software creator that corrects errors in the program or adds the necessary piece to allow the program to run on other computers.) The necessary programs are bundled (packaged together) in the Internet Access Kits along with the necessary configuration file.

Sharing Files and Collaborating At U-M and Around the WorldIt can be of critical importance in doing our work that we can easily share files and communicate with colleagues and co-workers. Moving documents and other files to others at U-M and to people and places around the world is easily accomplished using various local and wide area networks. Methods of moving files and documents include: a) attaching the document or file to an e-mail message, (methods for doing this vary depending on the type of e-mail program being used.); b) dropping or retrieving files to or from another user’s public folder or directory on their computer; or, c) dropping or retrieving files to or from a coworker’s folder or directory stored on the IFS server (see below), d) or, to or from a departmental server.

**The Institutional File System (IFS)The Institutional File System (IFS) at U-M is a flexible, secure mechanism for collaborating and sharing information among users. File storage space on IFS is apportioned into “home directories” that are assigned to groups and individuals. You can store files, share them, and retrieve them from Macintosh, Unix, and DOS/Windows computers, at work, at home, or in many locations around the world.

IFS group directories are used for sharing program assignments, research results, and for storing departmental and individual World-Wide Web home pages. Group directories are also accessible from many locations world-wide.

IFS has some special features. The entire contents of IFS are backed-up on a regular basis, providing security for your work. Since the U-M IFS is part of the Andrew File System (AFS) which is available world-wide, members of the U-M community have world-wide access to information.

An IFS home directory is included in the set of services provided by ITD’s UMCE (University of Michigan Computing Environment) Subscription Service. The basic account is 5MB of storage space—additional space can be purchased. This storage space resides on a series of servers and related support systems on the U-M campus that make up the IFS service.

The IFS server includes the swdist area which allows U-M people to make copies of software that is commonly used at the University to use on their own computers. The swdist directory is especially handy for copying client software to your computer for use with some of the tools unique to the U-M campus. Many of the programs and services are discussed in this workshop.

IFS is available directly on Macintosh computers using the Chooser. On Intel (Windows) computers, you will need to telnet to the server.

Software:NCSA Telnet and MacTCP are available in the swdist folder/directory on the IFS server.

FTP (File Transfer Protocol)FTP (File Transfer Protocol) allows a user to transfer files between any two computers connected through the Internet. There are vast archives of files on public sites throughout the world. You do not need an account or password on the host computer to use its public files. Accessing these sites is done via anonymous FTP. Fetch is a FTP client software program for Macintosh; Rapid Filer works on Windows machines.

Computer Conferencing As A Tool for Collaboration

Local- and Wide-area Conferencing Using Discussion Groups Electronic-mail (e-mail) is generally used for communication between individuals, or between an individual and a group. Various other services—conferencing programs—exist to allow entire groups to participate in online discussion groups.

The three most commonly used conferencing programs at U-M are: Confer U, and Lotus Notes. Your choice will be based on where the information you need to access resides, and the type of hardware you have. Also to be considered are whether you need to “download” conference entries to work on another machine which may be disconnected from networks, such as a laptop.

**Computer Conferencing Using Confer UConfer U is a U-M based program that allows individuals or groups to set up an electronic discussion on a given theme or for a specific purpose. Participants join the conference, enter items for discussion, and respond to previously entered items.

Conferences can be public, open to anyone at the University with a uniqname, or private ones, restricted to a specific group, such as a class, organization, or work group. There are many public conferences for general socializing or discussions of a wide range of topics. Confer U can be accessed from anywhere you can use telnet, including the U-M ITD Login Server. This program allows for conferencing on MichNet. It is also possible to access commercial networks using Confer U. (Information about this is included in the Computing Handbook.)





Beginning a Confer U conference at U-M

Confer U is a program that can be used without TCP/IP connectivity, as it can be accessed by VT100 emulation, using any communications software such as VersaTerm or PROCOMM.

To Use the ITD Confer Host:There is a fee for using this service. You need a uniqname and UMICH password, and a subscription to Confer U. You also need client software to connect to the Confer host. You also need to know the name of the conference you wish to participate in. In order to login to a conference, you telnet to the Confer host using its host name.


ITD Documentation:See Computer Conferencing Using Confer U, ITD Documentation, Series Title: Tutorial T7034Conferencing Options Decision Tool, ITD Documentation, Series Title: Reference R1143 Electronic Conferencing at a Glance, ITD Documentation, Series Title: Reference R1142

**Computer Conferencing Using Lotus NotesLotus Notes is an application that combines conferencing, electronic forms, and other capabilities. It is described as “groupware” because it facilitates collaborative interactions on documents among a group of users. It offers discussion groups, database services, a Web browser, directory services, e-mail, workflow, and other services, in addition to supporting basic productivity software such as word processing, spreadsheeting, etc. The user interface is the same for different applications—creating ease-of-use efficiencies.

Departments, classes, work groups, and student organizations can set up a Lotus Notes service for collaborative interactions on shared documents. There is a charge for using this program. The program does require some training in order to make the most effective use of it. (ITD currently offers workshops on the use of this program, for both Mac and Windows platforms.)

Uniqname and UMICH (Kerberos) PasswordIn order to use many of the computing resources available on the U-M campus, all faculty, staff, and students must have a computing ID which provides proof of their identity to the computing service providers. Your computing ID at U-M is a uniqname (pronounced “unique name”) and its accompanying UMICH password. Everyone connected to the U-M gets a uniqname when they come to the University; this same uniqname will stay with you as long as you are affiliated with U-M. Uniqnames are published along with other information about you in the online X.500 directory (we will demonstrate this later), for others to see and use in order to locate and communicate with you.

Uniqnames (unlike passwords) are difficult to change. You will want to choose your uniqname carefully. Uniqnames must be 3-8 lowercase characters with no spaces or punctuation, and one not already selected by another user.

A UMICH (Kerberos) password goes with your uniqname. This allows you to authenticate, or prove your uniqname identity when you access U-M computing services. (You do not tell anyone your password so that another person may not make unauthorized use of computing resources in your name.) Passwords can be changed, and, probably should be, from time to time. A Uniqname and UMICH password are required in order to use most of the services covered in this workshop.



If You Forget Your Uniqname or Password:If you forget your uniqname and it’s not printed on your ID card, you can look it up in the X.500 online directory. If you forget your UMICH password, you will need to go to the ITD Accounts Office in the lower level of the Michigan Union or the NUBS (North University Building) Computing Resource Site to get it reset.

**X.500 Online DirectoryTo send e-mail and collaborate online with colleagues, you will need to know their network addresses, in much the same way that you need to know the addresses and phone numbers of your family and friends in order to communicate with them by phone or US mail.

X.500 is the online directory (or “white pages”) that you use to look up people at the U-M and at other locations around the world. The directory lists peoples’ names, addresses, uniqnames, e-mail addresses, phone numbers and other useful information. The information about faculty and staff enters the U-M X.500 system from the University Personnel Office. Student information is entered from the Registrar’s Office. The information is updated regularly—every month or six weeks. Because the information is updated regularly, it is often more current than the annual printed directory. (If you have requested that information about you not appear in the University phone book, it will not appear in X.500.)

Other X.500 ServicesThe X.500 program provides other services besides directory information for people. The program allows for the creation of electronic mail groups, where a single message can be sent to a few or hundreds of individuals. The program allows a user to join and remove him/herself from these mail groups. Lists of membership in e-mail groups can also be printed.

ITD-produced user documents that provide detailed instructions about how to use computer technology are listed in the X.500 directory. Hundreds of these useful documents, which can be printed on almost any local printer, are available online.

When you are away from your job for any extended length of time—on University business, vacation, or sick leave—X.500 makes it possible for you to set up e-mail messages that will notify those sending e-mail to you that you are not reading messages for a given length of time.

X.500 is one of the ITD services that requires a uniqname and password in order to use it. It is a client/server program, which is a software program that allows your computer to access programs and data stored on one or more computing servers. It is necessary to have the appropriate client software loaded on your computer in order to access this program. There are separate versions of the program for the three most commonly used U-M desktop computer platforms: Macintosh,



Windows, and UNIX. (There is no version of X.500 available for DOS.) While the program versions are basically similar, there are some differences between them.

Connecting Your Computer to the U-M Network, MichNet, and the InternetIn order to use the vast number of computing resources available at U-M and around the world, your computer needs to be, and probably is, connected to the University backbone network. There are two primary ways a user can physically connect to the network. Your computer may be directly connected with Ethernet cabling, or you may connect by dialing-in over telephone lines using a modem.

Direct Connections—EthernetMost campus offices and laboratories, as well as the Campus Computing Sites, ResComp Sites and rooms in residence halls are directly connected to the campus network, and therefore, MichNet and the Internet, with Ethernet (TCP/IP compatible) cabling.

Dial-in Access of the U-M Network Using a NAS (Network Access Server) (from a Remote, off-campus, Site), Using A ModemUniversity faculty, staff, and students, who have a uniqname, password, and account, can also connect a computer to the campus network from any location by using a modem and a telephone line to dial in to a Network Access Server (NAS). Note that Ethernet connections typically provide much faster connections than do modem connections.

Through the use of a NAS, you can either: a) use full Internet services with the help of PPP (Point-to-Point Protocol), (PPP allows you to use TCP/IP over a dial-in connection);b) connect to Internet hosts without using other types of Internet services, if you have non-PPP or terminal emulation software.

After you have connected to the network through direct cabling or a modem, you will need networking and communications software that’s appropriate for your kind of computer and network.

Software for TCP/IP connectivity (for Ethernet or modem connections) is conveniently bundled into Internet Access Kits, which can be copied directly onto your computer hard drive. You can download the appropriate kit onto disks and then onto your computer’s hard drive from the disks. Be sure to check the readme files included with software for installation procedures.

System Requirements for Using the Internet Access KitsMinimum requirements: 4MB RAM, a hard drive, a high-density disk drive. For dialing in, you will need a modem with a speed of 9600bps—14,400bps or higher is recommended. Macintosh users need System 7 or later. Windows system requirements include a 386sx processor or later and Windows 3.1 or later.

For those whose computers do not meet the system requirements for using one of the Internet Access Kits, connection to the campus network is possible. You will not be able to open a TCP/IP session or use the various client programs. However, you can still access your electronic mail (with Pine e-mail program), and use some of the Internet features through the ITD Login Service with the help of terminal emulation software. (Terminal emulation software allows your computer to function like a terminal to another computer and to access information on this other computer.) ITD supports two packages for terminal emulation: VersaTerm for Macintosh computers, and PROCOMM PLUS for DOS machines. A 2400bps modem speed is minimum for connection to a NAS.

**The UMCE (University of Michigan Computing Environment) Subscription ServiceA UMCE account is required for using many of the computing services mentioned in this workshop as you are charged for their use. ITD automatically deposits funding (called a computing) allocation for Ann Arbor campus staff, faculty, and students in their UMCE Individual Accounts on the first working day of each month. The allocations are large enough so that most people have sufficient funding to cover their computing activities. You can accumulate up to two months worth of funds in your UMCE Individual Account. You can use the funds in your account to pay for a variety of computing services, such as e-mail, file space, Confer U, the ITD Statistics Service, and dial-in access.

**Obtaining Software at the U-MBesides providing some of the best academic computing technology to faculty, staff, and students, the U-M makes hundreds of software programs available either free-of-charge, or at significantly reduced prices. The software consists of two large collections of software that are available for copy to all members of the University community.





Accessing the U-M Software Distribution Service on a Macintosh computer

The U-M software collections are the Software Archives and the Software Distribution directory. Both of these software collections include software for Macintosh, Windows, and Unix computers. Everything is stored on the IFS server(s). It is possible to access the Merit/U-M Software Archives on the U-M GOpherBLUE server.

The U-M Software ArchivesThe U-M Software Archives, sometimes called the Merit/U-M Software Archives, provide a useful collection of data, text, and programs for both Macintosh and Windows. Everythingfrom electronic magazines to games to sound files is available here, including such programs as a generic version of maX.500. This collection contains thousands of programs including public domain, and shareware programs. Public domain software programs are ones madeavailable free by the programmers. Shareware is software also provided by its creators, who request a small fee if you like and use the program(s). Paying the reduced fees makes you a registered user, as a result you will often receive documentation and program upgrades.

The U-M maintains the Archive collection as a service to all people using the Internet. These programs are available to anyone using the Internet, and hence are available to any U-M faculty, staff, or student. Users may also access these programs using the FTP client Fetch, or Rapid Filer to connect via anonymous FTP to archive.umich.edu.

The U-M Software Distribution SystemThe other collection of software stored in the swdist directory on IFS is available to all members of the U-M community who have a uniqname and umich password. This collection



includes software that is free, requires a fee, or is site-licensed. Site-licensed software programs are programs that the University has obtained for use by all membersof the U-M community either free, or by purchasing a single license for the entire University. These programs are available free or at a reduced fee to all or part of the U-M community.

Programs included in the swdist directory are: X.500 versions which has been adapted for the University of Michigan Computing Environment (UMCE). Also Eudora e-mail, SPSS and SAS statistical software, as well as many other commercial products and upgrades.

Availability of Other (Productivity) SoftwareThe University also makes bulk purchase agreements and educational discounts on software such as Microsoft Word and Excel, Aldus PageMaker, and Claris FileMaker Pro. These programs are available for purchase from Photo and Campus Services, now adjacent to the Computer Showcase on the lower level of the Michigan Union. See GOpherBLUE for pricing and availability.

Computing Rights and ResponsibilitiesUniversity-provided computers and networks are shared resources of the University—much like the library collections and other facilities. It is up to each individual to learn about these resources and use them appropriately.

Policies and GuidelinesThe University’s Proper Use Policy and Guidelines for Responsible Use describe the responsible, ethical, and legal use of computing resources for the protection of all users. We encourage you to read these documents, ask questions, and help us maintain an open community of responsible users.

As a member of the U-M computing community, you are expected to follow certain standards of behavior. When you use the University’s technology services, you accept the following specific responsibilities:

∑ To respect the privacy of other users.∑ To respect the rights of other users.∑ To respect the legal protection provided by copyright and licensing of data and programs.∑ To respect the intended use of resources∑ To respect the intended use of systems for electronic exchange, such as e-mail.∑ To respect the integrity of the system or network.∑ To respect the financial structure of a computing or networking system.∑ To adhere to all General University Policies and Procedures.

Violations of Guidelines for Responsible UseViolations of the above guidelines are certainly unethical and may be violations of University policy or criminal offenses. You are expected to report information you may have concerning instances in which the above guidelines have been or are being violated.

In accordance with the established University practices, policies, and procedures, confirmation of inappropriate use of U-M technology resources may result in termination of access, disciplinary review, expulsion from the University, termination of employment, legal action or other disciplinary action.

Questions about the Guidelines for Responsible Use and reports of possible violations of the Guidelines or the Proper Use Policy to the ITD User Advocate ([email protected] or call (76)38940.



The Proper Use of Information Resources, Information Technology, and Networks at the University of MichiganIt is the policy of the University to maintain access for its community to local, national, and international sources of information and to provide an atmosphere that encourages access to knowledge and sharing of information.

It is the policy of the University that information resources will be used by members of its community with respect for the public trust through which they have been provided and in accordance with policy and regulations established from time to time by the University and its operating units.

In accordance with the above policies, the University works to create an intellectual environment in which students, staff, and faculty may feel free to create and to collaborate with colleagues both at the University of Michigan and at other institutions, without fear that the products of their intellectual efforts will be violated by misrepresentation, tampering, destruction, and/or theft.

Access to the information resource infrastructure both within the University and beyond the campus, sharing of information, and security of the intellectual products of the community all require that each and every user accept responsibility to protect the rights of the community. Any member of the University community who, without authorization, accesses, uses, destroys, alters, dismantles, or disfigures the University information technologies, properties, or facilities, including those owned by third parties, thereby threatens the atmosphere of increased access and sharing of information, threatens the security within which members of the community may create intellectual products and maintain records, and in light of the University’s policy in this area, has engaged in unethical and unacceptable conduct. Access to the networks and to the information technology environment at the University of Michigan is a privilege and must be treated as such by all users of these systems.

To ensure the existence of this information resource environment, members of the University community will take actions, in concert with State and Federal agencies and other interested parties, to identify and to set up technical and procedural mechanisms to make the information technology environment at the University of Michigan and its internal and external networks resistant to disruption.

In the final analysis, the health and well-being of this resource is the responsibility of its users, who must all guard against abuses which disrupt and/or threaten the long-term viability of the systems at the University of Michigan and those beyond the University. The University requires that members of its community act in accordance with these responsibilities, this policy, relevant laws and contractual obligations, and the highest standard of ethics.

Though not exhaustive, the following material defines the University’s position regarding several general issues in this area.*The University characterizes as unethical and unacceptable, and just cause for taking disciplinary action up to and including non-reappointment, discharge, dismissal, and/or legal action, any activity through which an individual:

(a) violates such matters as University or third-party copyright or patent protection and authorizations, as well as license agreements and other contracts,(b) interferes with the intended use of the information resources,(c) seeks to gain or gains unauthorized access to information resources,



(d) without authorization, destroys, alters, dismantles, disfigures, prevents rightful access to, or otherwise interferes with the integrity of computer-based information and/or information resources,(e) without authorization invades the privacy of individuals or entities that are creators, authors, users, or subjects of the information resources.

This policy is applicable to any member of the University community, whether at the University or elsewhere, and refers to all information resources, whether individually controlled, shared, stand alone, or networked. Individual units within the University may define “conditions of use” for facilities under their control. These statements must be consistent with this overall policy but may provide additional detail, guidelines, and/or restrictions. Where such “conditions or use” exists, enforcement mechanisms defined therein shall apply. Where no enforcement mechanism exists, the enforcement mechanism defined in the Guidelines for Implementing the Proper Use Policy of the University of Michigan: Responsible Use of Technology Resources shall prevail. Disciplinary action, if any, for faculty and staff shall be consistent with the University Standard Practice Guides and the Bylaws of the Regents of the University. Where use of external networks is involved, policies governing such use also are applicable and must be adhered to.

*Information resources in this document are meant to include any information in electronic or audiovisual format or any hardware or software that make possible the storage and use of such information. As example, included in this definition are electronic mail, local databases, externally accessed databases, CD-ROM, motion picture film, recorded magnetic media, photographs, and digitized information such as the content of MIRLYN.

Glossary

access To access something on a computer system is to use it. However, first you much switch to where the thing to be accessed is stored, or, you must tell the computer where it is located. You may also need a password before you can use the information that is needed.

browser A browser is World-Wide Web server software that allows the user to locate information on the Web.

CD-ROM This is the acronym for “compact disk, read-only memory.” CD-ROMs look like the CDs we use to play music. To use these with your computer, you need a CD-ROM player or drive. A CD-ROM can hold up to 600MB of information—the equivalent of about 700 floppy diskettes. There are CD-ROMS that hold encyclopedias, complete with video clips of moving animals, etc., the entire works of Shakespeare, and huge collections of graphic images and photographs.

client A networked computer, often on a user’s desktop, that may access servers. The servers “serve” information to the user’s computer, which is referred to as the “client.”

dial-in access Most desktop computers on the U-M campuses are directly connected (by cable) to the U-M network. It is possible to connect computers off-campus (at home or elsewhere), by dialing in to the network using the common telephone lines.

Ethernet Ethernet is a type local area network (LAN) connecting computers together with cables so the computers can share information. Within each main branch of the network, Ethernet can connect up to 1,024 personal computers and workstations. EtherTalk is the Apple Computer software that allows Macintosh computers to connect to Ethernet networks. To use EtherTalk and Ethernet, Macs must have an Ethernet interface card installed inside the computer. (In an ad like 8/80E, the E means the computer includes the Ethernet interface card. (The numbers indicate the amount of RAM and hard disk space in megabytes.)



Ethernet, which is widely used on the U-M campus for Macintosh, DOS/Windows, and Unix-based LANa, refers both to an international LAN standard and the cabling that carries data supporting the standard. Invented at Xerox, Ethernet was the first multi-vendor LAN technology, and allows computers and networks made by various manufacturers to interoperate.

Ethernet is popular because it is relatively fast (10 million bps); uses inexpensive, readily available cabling; and is quite easy to install.

flame Computer users who express their opinion or feelings across a computer network in heated, emotional, and thoroughly disagreeable manner are said to be “flaming.”

hard copy A hard copy is a printed version of a document that was created on a computer. It may be on paper, film, or any other “permanent” medium. A copy of the document stored on a computer is a file, sometimes called a “soft copy.”

home page A home page is the basic World-Wide Web page for an individual’s or organization’s entry.

IMAP e-mail client Interactive Mail Application Protocol. IMAP e-mail (Pine and Mail Drop) clients store and process mail from a central server. Messages can be accessed from many computer locations.

Kerberos A password and security mechanism developed at MIT that is used during the authentication process in IFS.

MacTCP This is a Macintosh Control Panel. It is Apple’s implementation of the TCP/IP protocols. MacTCP is a Macintosh operating system driver that lets a Macintosh communicate with other computers that use the TCP Internet Protocols.

modem A modem is a device that allows computers or other electronic devices to communicate via telephone lines. Computers represent information digitally, as discrete packets of current, or bits. Telephone lines carry analog information, continuous, fluctuating waves of current whose frequencies are in the range you can hear. Modems are used to translate between the two types of information.

NCSA Telnet This software allows users to connect to other hosts (computers and services) on the Internet, including the



U-M Computing Environment (UMCE) services. NCSA Telnet is TCP/IP client software.

news reader A software application that can connect to a news server and retrieve articles from that server. Nuntius is a news reader.

patch A patch is a small program supplied by the software creator that corrects errors in the program or adds the necessary piece to allow the program to run on other computers. A patch may be a program upgrade.

POP e-mail Post Office Protocol software (Eudora) downloads messages and stores them on the computer’s hard drive, thus you cannot easily read your messages from another computer.
