Types of general-purpose application software Personal productivity programs Multimedia and graphics software Applications that work through and

run from the Internet Home and education programs



Personal productivity programs Make it easier to do

work Examples

Word-processing software

Spreadsheet or database software

Presentation software



Multimedia and graphics software includes the use of two or more media, such as graphics plus video or audio.



Multimedia and graphics software programs Professional desktop publishing Multimedia authoring Paint, drawing, and animation Image editing 3D rendering Audio Video editing



Animation programs give the user the ability to create animation from images and run the animation.



Audio software is used to capture and process sound used in multimedia presentations.



Standard sound file formats MP3 Windows Media Audio (WMA) WAV Musical Instrument Digital Interface

(MIDI)



Video editors enable the user to: Modify digitized videos. Save those videos in at least one of

the following video file formats: Moving Picture Experts Group

(MPEG) Video for Windows




Multimedia authoring systems Used to create multimedia presentations Require a large amount of disk space and

memory to run properly

E-mail Instant messaging software Web browsers Video conferencing programs



Web-hosted technology Share files and collaborate.

Windows Office Live Google Docs

Undesirable Internet software Spyware monitors your activity. Adware targets products to your

interests.



Home and educational programs Computerized reference software Personal finance software Computer games


Tailor-Made Applications

Software designed for specific businesses or users are known as tailor-made applications.

Tailor-made applications normally cost more than general-purpose applications because of their development costs.


Tailor-Made Applications

Custom software, developed for a user’s specific needs, may be necessary when an application is not available.

Packaged software is developed for the mass market.


A fully self-contained program is called a standalone program.

Advantages Purchased and installed separately Function by themselves

Disadvantages Take a lot of storage space Do not share resources


Standalone Programs, Integrated Programs, & Software Suites

Integrated programs provide leading productivity programs in one package. Easy to learn and share the same

interface Example: Microsoft Works

Have fewer features than standalone programs and software suitesCopyright © 2011 Pearson Education, Inc. Publishing as Prentice

Standalone Programs, Integrated Programs, & Software Suites

System Requirements & Software Versions

System requirements outline the minimal level of resources that a program requires.

Releases of programs are cited by a year or version number. In a version number, a decimal

number indicates a maintenance release.


System Requirements & Software Versions

Software is kept current through software upgrading. Small fixes to software are called

patches. Large or major fixes to software are

called service packs or service releases.

Software can be distributed through the Internet and purchased in stores.Copyright © 2011 Pearson Education, Inc. Publishing as Prentice

Software Licenses & Registration

A contract included with purchased software that permits the user to install the program on one computer is known as a software license.

A contract that gives organizations the right to install copies of programs on a precise number of computers is known as a site license.


Installing & Managing Application Software

Installing software on a computer involves moving the software to the hard disk and properly configuring the software.

Uninstalling software takes the program off the hard disk.

Launching software moves it from the hard disk to memory.

Chapter 6: The Internet and the World Wide Web


How the Internet Works

The Internet is a universal system of computers and networks.

Cyberspace, a term used to refer to the Internet, is the unlimited span of networks using the same data exchange methods.


The Internet and the Web: What’s the Difference?

The World Wide Web, also known as the Web or WWW: Contains billions of documents Is a portion of the Internet Uses the Internet as a means to

transport information Is a separate entity from the Internet



The Web contains the information.

The Internet transports information to and from users.




A Web page is a document that may include text, graphics, sound, animation, and video.

A Web site is a collection of Web pages.

A Web browser is a program that displays Web pages and linked items.



Hyperlinks or links are words and images that bring other documents into view when clicked.

Hypertext uses links to move to additional related information.

Hypertext Markup Language (HTML) uses tags to specify how a Web page should display.


The most popular Web browsers Mozilla Firefox Google Chrome Internet Explorer Opera Safari



Web sites and their associated information are stored on computers called Web servers.

Web servers are used to recognize information requests, process the requests, and send the requested documents.



Every device connected to the Internet, including PCs and servers, is given a unique network identifier called an Internet Protocol (IP) address.

The identification of an Internet resource’s type and location is performed through its Uniform Resource Locator (URL).



The complete URL is made up of the Hypertext Transfer Protocol (HTTP), domain name, path, and resource name.



Ways to access a Web page Type a URL into the address bar. Click a tab in the browser window. Click a hyperlink.

The history list compiles a list of the Web pages that the user has visited.






Downloading is the process of transferring a file or document from one computer to the user’s computer.

Uploading is the process of transferring a file or document from the user’s computer to another computer.

Finding Information on the Web


A subject guide, where Web pages are grouped under specific headings, is offered by some search sites.


Search engines index databases of Web pages to enable fast information searches.



Specialized search engines index information such as job advertisements, and names and addresses.

Some Web site home pages include portals, which provide organized subject guide links to topics such as the news, local weather, and e-mail. Copyright © 2011 Pearson Education, Inc. Publishing as Prentice

Hall 39


Example of a portal



Search operators are used to perform complex searches.

Inclusion operators, generally a plus sign (+), are used so that only Web pages including those criteria are retrieved.

Exclusion operators, generally a minus sign (-), are used so that only Web pages excluding those criteria are retrieved.



Wildcard symbols, such as ? and *, replace the zero or additional characters in search words to improve search accuracy.

In phrase searching, the user places quotation marks around a phrase to create a complete unit for search purposes. As a result, search engines retrieve only those sites that contain the exact phrase.


Exploring Internet Services

Electronic mail (e-mail) is a type of application software that makes sending and receiving messages through computer networks possible.

An e-mail attachment is a computer file included with an e-mail message.



An e-mail address, a unique cyberspace address for each individual, consists of a user name, the name of the hosting e-mail service, and the top-level domain.

Unsolicited e-mails received by users, usually from advertisers, are called spam. Do not open spam.



File Transfer Protocol (FTP) is a method used to transfer files over the Internet. Use when files are too large to

attach to e-mails. Avoid sending sensitive material to

an anonymous FTP site. Use to upload Web pages.


E-Commerce

E-commerce is the conducting of business through the use of networks or the Internet.

Business-to-Business (B2B) E-Commerce refers to a business providing supplies to other businesses via the Internet.


E-Commerce

Consumer-to-Consumer (C2C) E-Commerce refers to the exchange of business between individuals. eBay is a good example.

Business-to-Consumer (B2C) E-Commerce refers to shopping online rather than at a physical store.
