Data communications is transmission, reception, and processing of digital information. Depending on the type of network that we need to install, some network components can also be removed. There are five elements of a data communication system:- Message Sender Receiver Medium (Communication Channel) Encoder & Decoder Components of Data Communication: 1.Sender 2.Receiver 3.Message 4.Tramsmission Medium 5. Sender. Sender: The sender is the device that sends the data message. For data communications to occur, the communicating devices must be part of a communication system made up of a combination of hardware (physical equipment) and software (programs). Data communication protocols are very important for communication – they are needed for networks/computers/devices to understand each other. Popular forms of information include text, pictures, audio, video etc.2. In this guide, we will discuss the main components of a computer network. Each of these is discussed in detail.

For communication to take place, the SECTION 1: TYPES AND COMPONENTS OF COMPUTER SYSTEMS IGCSE ICT-0417@ VKS-Learning Hub Page 4 MAIN COMPONENTS OF COMPUTER SYSTEMS A computer is an electronic device, operating under the control of instructions stored in its own memory. In basic terms, humans communicate through a process of encoding and decoding.The encoder is the person who develops and sends the message. Different Data Flow Directions. Effective communication is not just a business skill-it is a life skill and the most important source of personal power at work, family and social situations. The four essential components of data communications are a sender, a receiver, a channel, and a protocol. According to E Computer Notes, the five major components of a data communications system are the message, sender, receiver, medium and protocol. Message 2. It is a two-way process and takes Place over time rather than instantaneously. The Fig. The basic components of data communications are as follows: 1. The medium is the channel over which the message is sent and the protocol is the set of rules that guides how the data is transmitted from encoding to decoding. 3 Communications Process: Encoding and Decoding . Channel gt The message needs some kind of medium to be transmitted. Looks like you’ve clipped this slide to already.
