4. Definition a of Computer Network Referred to as a Network, is a collection of computers and devices interconnected by communication channels that facilitate communications among users and allows users to share resources allows sharing of resources and information among interconnected devices.

5. History of a Computer Network Networks of communicating computers included the military radar system Semi Automatic Ground Environment (SAGE) and its relative the commercial airline reservation system Semi Automatic Business Research Environment (SABRE) Came about in the late 1950’s Although in the 1960’s the Advanced Research Projects Agency (ADRPA) started funding the design of the ADRPA in order to perfect networks for the United States Department of Defense

6. Purposes of a Computer Network and its Importance Computer networks were invented to that people all around the world could receive and send information through signals and connections to and from computer almost everywhere around the world So people could get signal or internet connection to view documents and surf the web (varies by person) Links many computers to the same printers scanners, monitors etc. Connects computers to the same internet connection, and enables them to share information without being concerned with it being compromised. They can be used to block websites.

11. Geographical Point of View

14. WAN

16. WAN Network A WAN network is used for a network that covers a city, or country. This type of network is usually provided by cell phone companies

17. MAN/CAN Network A CAN network is used to link buildings within a campus together, providing direct accessibility from each building. A MAN network, like the WAN network is used for long distance, up to 30 miles. It is also used for carrying information at higher speeds, upwards of 100 megabites per second.
