Email and groupware

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

Disadvantages of Email
 E-Mail Overload
 Time consuming
 E-mail and Excuse
 Infecting your computer with a virus
 Ignorance

Email Providers
 Gmail.
 Yahoo mail.
 Rediff mail.
 Hotmail.

Bouncing of Email
Due 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 Groupware
Groupware is often broken down into categories describing
whether or not work group members collaborate in real
time.
 Lotus Notes and Microsoft Exchange
Both 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 Matrix

at the same time or not

Uses
 Communicate
 Cooperate
 Coordinate
 Solve problems
 Compete
 Negotiate

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.
