Communicate via the Internet
1. Email:
•
•
A shortened form of "electronic mail," an email works much like
traditional mail in that messages are still sent by one person, received
and sometimes saved by another, but the process is instantaneous.
Users are given a unique email address from which messages are
passed back and forth. Additionally, one message can be sent to
several recipients simultaneously.

2. Instant Messaging:
•
•
An instant message, or IM, is the process of sending real-time
messages from one user to another. One user types a message that is
conveyed over a network and received by the other user.
Instant messaging can be between two or more people using a
specific program such as Yahoo Messenger or Windows Live
Messenger.

Chat Room:
A chat room is an "area" on the Internet where groups of people come
together to communicate. A user types a message that is seen by all
other users currently online in the same "room.“
Users can see a list of all other users online. If a user right-clicks
another user name, they are able to view his profile and send a private
message.

7. Blog:
•
•
A blog is an online journal, or diary, of an individual. Typically written

8. Audio Conferencing:
•
•
Audio conferencing is a connection between two computers that
requires participants to have a microphone and speakers.
Using an instant messaging program, such as America Online
Messenger (AOL), or an audio conferencing software, such as Skype,
users speak into the microphone and the dialogue is heard through
the speakers of the other users.

9. Video Conferencing:
•
Video conferencing works much like audio conferencing. The
differences are that the users are able to see each other -- and for this
a webcam is needed by all parties -- and that depending upon the
service used, multiple people can see and be seen at the same time.

10. VoIP:
•
•
Voice over Internet protocol, or VoIP, is phone service through an
Internet connection. Users are given an adapter and a unique phone
number.
The user can then send and receive phone calls using a computer, a
VoIP phone or a traditional phone, to and from other people, whether
or not they use VoIP themselves.

Apply for jobs via the Internet
• The Internet is becoming an essential job-search tool. Understanding
how it works and its advantages and disadvantages will be helpful to the
job seeker.
• The Internet represents a powerful, fast-changing fluid source of
information although it is not without its difficulties and frustrations. Those
using the Internet should be aware of the following caveats:
a)
The Internet is an ever-changing medium. Sites that are here today may be
gone tomorrow;
b) The Internet is becoming more and more commercial. Many sites that
promise help for the job-seeker simply want to sell something;
c) One of the Internet’s great advantages -- the ability to jump from site to site
by hyperlinks -- may also be its greatest disadvantage;
d) Just because it appears on the Internet does not mean that it is true or
accurate.

2. Linux:
•
•
Linux is, in simplest terms, an operating system. It is the software on a
computer that enables applications and the computer operator to
access the devices on the computer to perform desired functions.
The operating system (OS) relays instructions from an application to,
for instance, the computer's processor. The processor performs the
instructed task, then sends the results back to the application via the
operating system.
