Types of Networks
Local Area Networks:
Smaller networks that
connect machines in
local areas, such as a
classroom or school.
 Wide Area Network: A
network that connects
machines over a wide
area, such as schools
in a district or districts
in a state.

wireless technology
rather than across
actual wires.
Protocols
A common method of communication for
networks, so all network components understand
each other.
Bandwidth
Network communication channels vary in size
and speed. The less bandwidth the slower the
connection.
Security
Networks limit access to only those users that
have the right to use the network. This requires
a login name and password.
Privacy
Some areas are public and available to all users.
Confidential data should not be posted in these
areas.
