The following questions and activities are based on information the web site “An Educators Guide to School Networks” at http://fcit.coedu.usf.edu/network/default.htm and the video “Warriors of the Net”.

These questions are intended to be set after students have viewed the PowerPoint entitled ‘Network Hardware and Software’ that is part of this resource, and viewed the 13-minute video “Warriors of the Net”.

=Question 1=

List three reasons why an organisation might use a network rather than stand-alone computers.

1)     Sharing of Recourses

Wireless networks have many advantages. They allow laptop users to connect to the network anywhere within a building. They also make the process of laying cables – crawling through roof spaces, installing network points etc – unnecessary. What are some of the disadvantages of wireless networks?

Security

Interference

Power consumption

Speed

Inconsistent connections
