Instant messaging
is online, real-time communication between two or more people who
are connected to the Internet. With instant messaging, two or more windows or panes open,
with each one displaying text a person is typing. Because the typing is displayed in real time,
instant messaging is like talking to someone using the keyboard. See Figure 7.11.

Instant Messaging
Instant messaging lets you converse
with another Internet user by
exchanging messages
instantaneously.
Many companies offer instant messaging, including America Online, Yahoo!, and Mi-
crosoft. America Online is one of the leaders in instant messaging, with millions of people
using AOL Instant Messenger (AIM) and its client program ICQ. In addition to being able
to type messages on a keyboard and have the information instantly displayed on the other
person's screen, some instant messaging programs are allowing voice communication or
connection to cell phones. Today, instant messaging can be delivered over the Internet,
through the cell phone services, and via other telecommunications services first discussed in
Chapter 6.
As more people are connecting to the Internet over broadband connections, increasing
numbers of users are turning to video chat. Services such as Apple iChat and Skype provide
computer-to-computer video chat so users can speak to each other face-to-face. Some video
chat services support conference calling as well.
Career Information and Job Searching
The Internet is an excellent source of job-related information. People looking for their first
job or seeking information about new job opportunities can find a wealth of information.
Search engines can be a good starting point for searching for specific companies or industries.
You can use a directory on Yahoo's home page, for example, to explore industries and careers.
Most medium and large companies have Internet sites that list open positions, salaries, ben-
efits, and people to contact for further information. The IBM Web site,
www.ibm.com
,
has
a link to “Jobs at IBM.” When you click this link, you can find information on jobs with
IBM around the world. Some Internet sites specialize in certain careers or industries. The
site
www.directmarketingcareers.com
lists direct marketing jobs and careers. Some sites can
help you develop a résumé and find a good job. They can also help you develop an effective
cover letter for a résumé, prepare for a job interview, negotiate an employment contract,
and more. In addition, several Internet sites specialize in helping you find job information
and even apply for jobs online, including
www.monster.com
,
www.hotjobs.com
,
and
www.careerbuilder.com
.
You must be careful when applying for jobs online, however. Some
bogus companies or Web sites will steal your identity by asking for personal information.
People eager to get a job often give their Social Security number, birth date, and other personal
information. The result can be no job, large bills on your credit card, and ruined credit.
