[answerhappygod]

In an attempt to reduce collisions and interference, the
frequency space available to a wireless network may be divided into
channels. By making reference to 802.11b networks, explain how the
use of channels helps network administrators to manage their
network access points for reduced interference. Discuss the
difference between non-overlapping and partially overlapping
channels and explain why in certain circumstances (such as
residential streets) it is often preferable for households to make
use of one of the partially overlapping channels for their home
network, rather than one of the channels guaranteed not to
overlap.
