Networks
Types of Networks
A network can connect
two computers in a home
or millions of computers
around the world, as in
the case of the Internet.
Networks can be divided
into two basic categories:
• local area networks
• wide area networks
network A system in which
communication lines or
wireless connections are
used to connect computers
together. (p. 43)
local area network
(LAN) Type of network that
connects computers in a
single location, such as a
single department within a
company. (p. 43)
wide area network
(WAN) Network that
connects computers across
a wide geographical area,
such as a region of the
United States. (p. 43)

Chapter Review
Analyze Organizing and
keeping track of files is
an important part of
creating a Web site.
Why should you have a
plan when saving Web
site files?
You want to organize
and name your files
so they are easy to
find. Saving your
Web pages in a
system of folders
and subfolders will
make it easier and
quicker to update
and keep track of
Web site files.
