EMAIL AND GROUPWARE

Group 5.

Email Electronic mail, often abbreviated as email or e-

mail. Email – an electronic message transmitted over a

network from one user to another. Can be as simple as a few lines of text, or include

attachments such as pictures or documents. It is the method of exchanging digital messages

between two or more systems. E-mail systems are based on a store-and-forward

model. In which e-mail computer server systems accept,

forward, deliver and store messages on behalf of user.

Definition and History Electronic mail (or E-mail ) can be defined as

“the transformation of computer- stored messages by using telecommunications”

The first email systems were developed at SCD and MIT in 1965. Incompatible with each other, each system was designed to facilitate message delivery between users on a single machine.

Ray Tomlinson invented email back in 1971 – essentially fostering global business communication.

Advantages of Email

Screening information Bringing Work on the Road Sending Messages to Greet Managing E mail is easy and fast Email is easy to filter E-mails are delivered uninterruptedly

Bouncing of EmailDue to the following reasons e-mail will

bounce.

Mailbox Not Found

Invalid mailbox

Mailbox unavailable

Mailbox full

Host unknown.

Threats to Email E-mail spoofing Occurs when the header information of an

email is altered to make the message appear to come from a known or trusted source.

E-mail bombing Is the intentional sending of large volumes

of messages to a target address. The overloading of the target email address can render it unusable and can even cause the mail server to crash.

Groupware Programs that help people work together collectively

while located remotely from each other.

Often called collaborative software, groupware is an integral component of a field of study known as Computer-Supported Cooperative Work or CSCW.

Collaborative software, or groupware, is technology designed to facilitate the work of groups.

Programs that enable real time collaboration are called Synchronous Groupware.

Services Sharing of calendars.

Collective writing.

E-mail handling.

Shared database access.

Electronic meetings with each person able to see and display information to others, and other activities.

Products of GroupwareGroupware is often broken down into categories

describing whether or not work group members collaborate in real time.

Lotus Notes and Microsoft ExchangeBoth of which facilitate calendar sharing, e-mail handling, and the replication of files across a distributed system so that all users can view the same information.

CU-SeeMe and Microsoft NetMeeting.Electronic "face-to-face" meetings are facilitated.

The Time/Space MatrixClassify groupware by:

when the participants are working,at the same time or not

where the participants are working,at the same place or not

Groupware Different from Traditional User Interface Design?

While traditional technologies like the telephone qualify as groupware, groupware design involves understanding groups and how people behave in groups.

Involves having a good understanding of networking technology and how aspects of that technology affect a user’s experience.

Million-person groups behave differently from 5-person groups.

Performance parameters of the technologies to support different groups vary.

Ease-of-use must be better for groupware than for single-user systems because the pace of use of an application is often driven by the pace of a conversation.

System responsiveness and reliability.

Homogeneity of users, of the possible roles people play in cooperative work.

Categories

Groupware can be divided into three categories depending on the level of collaboration.

Communication  can be thought of as unstructured interchange of information. A phone call or an IM Chat discussion are examples of this.

Conferencing refers to interactive work toward a shared goal. Brainstorming or voting are examples of this.

Co-ordination refers to complex interdependent work toward a shared goal.

Design & Implementation Issues

Persistence is needed in some sessions.

Authentication has always been a problem with groupware.

Bandwidth issues at fixed location limited full use of the tools.

Multiple input and output streams bring concurrency issues into the groupware applications.
