1.What is a computer network?
-A computer network, often simply referred to as a network, is a collection of computers and devices connected by communications channels that facilitates communications among users and allows users to share resources with other users. Networks may be classified according to a wide variety of characteristics.


2.what are the types of network?
There are two types of networks
-Client/Server Networks
Client/server networks consist of two kinds of computer. The clients are usually computer workstations sitting on the desks of employees in an organisation. The servers are usually more powerful computers and are held in a central location or locations within an organisation.

-Peer-to-peer Networks
Peer-to-peer networks have workstations connected to each other but do not have servers.
Files can be shared between workstations, and a printer connected to one workstation can be accessed by another workstation.
Peer-to peer networks are often much simpler to set up than client/server networks. However, they lack some of the advantages normally associated with networks such as centrally managed security and ease of backing up files.
Peer-to-peer networks would really only be set up among a few computers within an office or single room.
