DATA COMMUNICATION AND NETWORKING

DATA COMMUNICATION 

data communication and networking

    Data communication is all about, how the communication is done between data. Simply we can say  that the communication between data and data is called data communication.

Data Communication Definition

    "The communication of data or the exchange of data between two or more devices/nodes by using some medium is called data communication."

    However the data may be in raw form or in form of information, which can be texts, numbers, images, audios and videos. And nodes are computers system, printers, server and other device that can hold data and can send or receive the data.

COMPONENT OF DATA COMMUNICATION

    Five component of data communication that are required that make us able to communicate data.

    1. Massage

    2. Sender

    3.Medium 

    4.Receiver 

    5.Protocol             See detail of data component of data communication 

CHARACTERISTIC OF DATA COMMUNICATION 

There are three main characteristic that should posses in a data communication process that are,

    1.Delivery  

    2.Acuuracy 

    3.Timelines

DATA FLOW IN COMMUNICATION 

Data flow or Mode of data communication. the movement and direction of data between nodes in a network. We have three type of data flow in communication or data communication mode.

    1.Simplex Mode

    2.Half-duplex Mode

    3.Full-duplex Mode  

NETWORK 

To make possible of the data communication between devices we need a strong network. That's why network define it self as " The interlink connection between device or node through a communication link (medium) to communicate data is called network".
