Data communications is the process of exchanging the data between two parties demanding the information. It is done by the means of a large number of varieties of mediums for transferring the data. In total this data communication system is nothing but the transfer of required data from one end of a gadget to the other end of another entirely different device via the medium of electricity or by the optical wire medium. The networking which supports this transmission of data among various devices or we can say to a number of points at the end are known as network of data communication.
These devices or gadgets that are in requirement of playing a role in this process of data communication are formed from the hardware of the computer and also its software.
The data communication process brings together the data from various data providing ends for instance the microphone and then allows the data to get transmitted to the end where the receiver is waiting for the message. This receiving destination could be anything like a laptop, desktop, mobile phones or microphones. But also, the opposite of the above discussed process can be done by networking of data communication, such as the source of the data that is going to be transferred by communication networks could be carried from a microphone, computer, desktop, etc to some other different device like a scanner or printer. The major five basic components of the system of data communications are known as Data, Sender, Receiver, Transmission Medium and Protocol.
Description of Basic Five Components of Data Communication
The process of communication or transferring of the data refers to a piece of information that is, the data is going to be transferred from one of the information giving device and to the device present at the receiving end also known as the destination point or the targeted point. Hence, the number one known component of the data communication system is called as data, information or message that needed to be transported whether in the form of a message to be delivered or the received information. The various types of data include information in the form of audio, text, image, video, or combined form of all these types etc.
- The Sender
One of the basic requirements of data communication is that the data or message is needed to be sent out by a source to a specific end point destination via a medium. The source sending the information is known as the sender. The gadget sending the data or message to the target or end destination is what we call the Sender machine or object. It can be anything, a computer, a microphone, mobile phone, laptop, pager, video camera, etc.
- Receiver – The Last Point
The receiver is the last destination of a data that is being transferred that is a receiver is the point where the data is finally obtained by a device. The data receiving device is known as the receiver. A receiver, like the sender gadget can be anything like a computer, microphone, mobile phone, or video or audio recording camera.
- Transmission Medium Helping In Transfer of Data
In the system of data communication, the medium of transferring the message or data is nothing but the path that is traveled by the data towards the final destination of the data when the sender had already dispatched it. The receiver is present at a particular end of the pathway and gains the message while the other end of the path belongs to the sender who sends the message. Various mediums of transmission like, coaxial cable, pair of twisted cable, optical fiber cable etc. are used for transferring of the message.
A set of well defined rules and regulations applicable on the entire process of data communication is known as the protocol. It is a kind of a contract amid the delivering and receiving devices to make the process a successful one. It includes rules for sending data, path and transmission of data, ensuring the receiving of data and handling of errors in the pathway, etc. The rules for both the sending and receiving devices are exactly same to avoid any discrepancy.…
