Importance of Communication Protocols

Home Importance of Communication Protocols


Communication is the process of conveying a message from one entity or person to another entity with the use of symbols, signs and semiotic rules. In every organization, there are two types of communication i.e. Verbal communication and non – verbal communication. Verbal communication takes place when the information and ideas are exchanged between different persons through words. Verbal communication occurs through letters, reports, calls, interview, radio, email and notes etc. On the other hand, non – verbal communication takes place when the information and ideas are exchanged through spoken words. This type of communication occurs through sending and receiving the message and the nature of these messages are wordless. Non- verbal communication occurs by using body languages such as – facial expressions, gestures, eye contact, touching etc.

Communication protocols

The communication protocol is a system of rules that allow two or more entities of a communication system for transmitting the information. In other words, communication protocol comprises the formal description of rules and formats of a digital message. These protocols are required to exchange the messages in the computing system and also needed in telecommunications. The protocols define the semantics, synchronization, syntax and rules of communication. The implementation of protocols may be implemented by software, hardware and both.

Types of communication protocols

Different types of Protocols involve – Hypertext transfer protocol, File transfer protocols, User datagram protocol, Simple mail transfer protocol, Post office protocol. These are explained as –

Hypertext Transfer Protocol (HTTP): It is an underlying protocol, which is used by the World Wide Web. The HTTP protocol explains how messages are transmitted and formatted, what actions browsers and Web servers should take in response to different commands.

File Transfer Protocol (FTP): The FTP is a standard internet protocol to transmit file between computers on the Internet over TCP/IP connections. Mainly, File Transfer Protocol, which relies on two-end communications channels between server and client.

User Datagram Protocol (UDP): The UDP protocol is an alternative communication protocol for the Transmission Control Protocol (TCP) is used primarily to establish loss tolerating and low-latency connections between applications on the internet. TCP and UDP both run on the top of Internet Protocol (IP) and it also referred to as the TCP/IP or UDP/IP.

Simple mail transfer protocol (SMTP): SMTP is a standard protocol, which is mainly used in email services over TCP/IP connections. The ability to send and receive email messages are provided by SMTP. SMTP is maintained and created by the Internet Engineering Task Force. Simple Mail Transfer Protocol (SMTP) is one of the popular and common protocols for email communication across the internet.

Post office protocol (POP): It is a type of internet standard protocol, which retrieves and extracts email from a remote mail server to access by the host machine. It is an application layer protocol of the OSI model, which provides the ability to end users in order to receive and fetch mail.

Transfer Control Protocol (TCP): TCP is a standard protocol, which defines how to maintain and establish a network conversation via which application programs can exchange information. TCP functions with the Internet Protocol (IP) that defines how computer devices send and receive packets of data with each other.

Process of Communication

The process of communication involves transmitting the message and information from the sender to the receiver. The communication process is a continuous and dynamic interaction which is affected by many variables. Different elements in the communication process are explained as -

Sender – The process of communication starts with the sender. The sender is the initiator that sends the message to another person. Sender encodes the message in different ways. Encoding is the process in which the sender translates his thoughts to the intended receiver. Example – sender translates his thoughts into actions.   

Transmission – The message can be transmitted by a sender to receiver through the channel of communication. The channel of communication involves a computer, a television, a memorandum and a telegram. The channels of communication can be selected with the situation of communication.   

Noise – Noise hinders the process of communication. The sender in the communications process should select a channel that is free from the noise. During transmission of the message, noise may occur at the end of the Sender. For Example – a poor telephone connection, faulty decoding, ambiguous symbols etc. 

Receiver – The person to whom the message is transmitted is known as Receiver. Firstly, the receiver receives the message in order to decoding. The decoding means the translation of symbols that are encoded by the sender into different ideas that can be understood. The process of communication can be considered as effective communication is both the sender and receiver understands similar meanings for the same message. 

Feedback – The information that is generated by the receiver in response to the sender’s message is known as Feedback. It is an important method that ensures the encoding, decoding of the message. Feedback by the receiver ensures that the message has been transmitted and understood effectively.
