Data communication fundamental characteristics and components

The exchange of data between devices by any transmission medium are
called as data communication. Communication medium like wire cable, wireless system are used. A communication system is necessary for Data communication. A communication system is made by using physical equipment’s and software’s. Physical equipment’s are called hardware.

There is basic 4 fundamental characteristics in data communication.

1. Delivery
2. Accuracy
3. Timeliness
4. Jitter

1.Delivery:System must have to send the data to the specific destination. The data finally have to be received by the receiver which intended for that data.

2.Accuracy:System must have to follow the accuracy in data transferring.

3.Timeliness:Data must have to be send in time. Otherwise the data will be useless.

4. Jitter:Uneven delay of packets are not friendly in data communication process.

Data communication components

In Data communication system there is 5 components. These are-

1. Message
2. Sender
3. Transmission Medium
4. Receiver
5. Protocol

1. Message: It is the information which to be send to the receiver. Information are text, audio, picture, video etc.

2. Sender: Sender sends the message to the transmission medium. Sender may be a computer, phone set etc.

3.Transmission Medium: Transmission medium is a physical path. From this path a message passes from sender to receiver. Example: Fiber optic cable, radio waves etc.

4.Receiver: Receiver receives the message from transmission medium which was send from the sender.

5.Protocol: Protocol is a set of some rules for data communication. By protocol sending and receiving process are maintained.
