B.     Answer the following questions:

1.     A computer network can be defined as a group of computers and other peripheral devices that are linked together for sharing data and hardware resources. For example if one of the computers in a network has a printer attached to it then all the computers in that network can access the printer.

2.     Uses of networking are:

                                                        i.            Efficient use of storage media

                                                      ii.            Preserving Information

                                                    iii.            Reduction in Hardware Cost

                                                   iv.            Efficiency

                                                     v.            Redundancy

                                                   vi.            Quickest Document Delivery

3.     Difference between LAN and WAN is:

Stands For	Local Area Network	Wide Area Network
Covers	Local areas only (e.g., homes, offices, schools)	Large geographic areas (e.g., cities, states, nations)
Definition	LAN (Local Area Network) is a computer network covering a small geographic area, like a home, office, school, or group of buildings.	WAN (Wide Area Network) is a computer network that covers a broad area (e.g., any network whose communications links cross metropolitan, regional, or national boundaries over a long distance).
Speed	High speed (1000 mbps)	Less speed (150 mbps)
Data transfer rates	LANs have a high data transfer rate.	WANs have a lower data transfer rate compared to LANs.
Example	The network in an office building can be a LAN	The Internet is a good example of a WAN

4.      Network Security means protecting data and resources from access by unauthorized persons. There are two levels of network security:

                                                        i.            Login Security:You are given a unique login name and password.

                                                     ii.            Rights Security:Based on user name read only or read write access is given.

5.      In this network  there is a main computer called server that provides services to clients and controls access to  all the resources.
