COMPONENT OF DATA COMMUNICATION

DATA COMMUNNICATION

components of data communication

" The process of data exchange between devices over a network through some communication medium is known as data communication".

    Components which is involved in this process of data communication is what we take as component of data communication.

COMPONENT OF DATA COMMUNICATION

For communication of data we need some components that allow us to communicating in other word that make the data communication possible, which are as follow

1.       Massage

Massage will be the data or information that has to communicate (send or receive) between nodes, where the data/information can be in different form like text, number, images, audio and video.

2.      Sender

Senders are those nodes that send the data. It can be computer, work station or mobile phone etc. sometimes we call sender as source system.

3.       Medium

Medium are also known as Transmission Medium. It is the path/way along which data travel form sender to receiver. Medium may be physical wire such as coaxial cable or may be wireless travel through air such as radio waves signal.

4.       Receiver

Receiver is the device which accepts the data and store, and can manipulate the data. Like sender receiver may be computer, server and workstation etc. sometime we use the word destination system as receiver.

5.       Protocols

Protocol means rule, there will be some set of rule specify to exchange the data between nodes is called protocol of data communication. Protocol represents the agreement of communicating nodes. Like how the data travel/move, how many data packet can travel on the medium, is the data packet move in parallel or in series. All this rules are defined in protocol. Every medium has own protocol by following the protocol the data communication done. Without protocol two devices can connect but can’t communicate.
