Switching And Switching Techniques In Data Communication

 Switching Techniques Switching techniques are used for transmitting data across networks. Different types of switching techniques are employed to provide communication between two computers. Which Are Circuit Switching Circuit switching is a methodology of implementing a telecommunication network in which two networks establish (circuit), a dedicated communication channel first through the network, and then the message is transmitted through the channels. The main advantage of circuit switching is guaranteed delivery. The circuit switching guarantees the full bandwidth of the channels and remains connected for the duration of the communication session.                    The defining example of a circuit-switched network is the early analog telephone network. When a call is made from one telephone to another, switches within the telephone exchanges create a continuous wire circuit between the two telephones for as long as the call lasts.

Computer Network and its benefits

 A network can be defined as an interconnected collection of autonomous computers. A 'Computer network' or a 'Network' is a collection of computers and other hardware devices, interconnected by communication channels that allow sharing of resources and information.

The speed of a network is measured in Mbps(Mega bits per second).

The computer network is very useful in the modern environment, so some of the benefits of networking are discussed here:-

(1.) File Sharing- Networking of computers helps the users to share data files.

(2.) Hardware Sharing- Users can share devices such as printers, scanners, CD-ROM drives, hard drives, etc.

(3.) Application Sharing- Applications can be shared over the network and this allows to implement the client/server applications.

(4.) User Communication- video conferencing within the network.

(5.) Access to Remote Database- By networking, we are able to access the remote database. It is easy for any person using his PC to make reservations for airplanes, trains, hotels, etc., anywhere in the world with instant confirmation within the network.
