What Is Protocol In Data Communication?

What is the function of protocol?


Protocols are a fundamental aspect of digital communication as they dictate how to format, transmit and receive data.

They are a set of rules that determines how the data will be transmitted over the network..

What are the two main functions of IP protocol?

An Internet Protocol address (IP address) is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. An IP address serves two main functions: host or network interface identification and location addressing.

How many types of protocols are there?

There are two common network protocols used to send data packets over a network. Together TCP as well as, UDP ahead the data packets through your device applying ports to different routers until they will connect with the last destination.

What layer is SMTP?

application layerSMTP is part of the application layer of the TCP/IP protocol. Using a process called “store and forward,” SMTP moves your email on and across networks. It works closely with something called the Mail Transfer Agent (MTA) to send your communication to the right computer and email inbox.

What is protocol with example?

A protocol is a standard set of rules that allow electronic devices to communicate with each other. … Protocols exist for several different applications. Examples include wired networking (e.g., Ethernet), wireless networking (e.g., 802.11ac), and Internet communication (e.g., IP).

Which is basic communication protocol?

Popular protocols include: File Transfer Protocol (FTP), TCP/IP, User Datagram Protocol (UDP), Hypertext Transfer Protocol (HTTP), Post Office Protocol (POP3), Internet Message Access Protocol (IMAP), Simple Mail Transfer Protocol (SMTP).

What is the importance of protocol?

When two devices want to successfully communicate, they must agree to follow some rules about the way they will do it. These are known as protocols. A communications protocol is the phrase used to describe a set of rules that communication equipment adhere to when they send data to each other.

What are the important elements of protocol?

The key elements of protocol are syntax, semantics and timing.Syntax: Syntax refers the structure and format of the information data.Semantics: Semantics refers to the meaning of each section of bits. … Timing: Timing refers to two characteristics: when data should be sent and how fast it should be sent.

What is protocol and its types?

A protocol is a set of rules that governs the communications between computers on a network. In order for two computers to talk to each other, they must be speaking the same language. … IP/IPX (Network Layer) TCP/SPX (Transport Layer) HTTP, FTP, Telnet, SMTP, and DNS(combined Session/Presentation/Application Layers)

What is the purpose of communication protocols?

A communication protocol is a system of rules that allow two or more entities of a communications system to transmit information via any kind of variation of a physical quantity. The protocol defines the rules, syntax, semantics and synchronization of communication and possible error recovery methods.

What are the different types of communication protocols used in PLC?

Some common protocols used in the industrial arena include:Modbus RTU.EtherNet/IP.Ethernet TCP/IP.Modbus TCP/IP.Profinet.

What is protocol in data communication network?

A network protocol is an established set of rules that determine how data is transmitted between different devices in the same network. Essentially, it allows connected devices to communicate with each other, regardless of any differences in their internal processes, structure or design.

What is TCP and UDP?

TCP is a connection-oriented protocol and UDP is a connection-less protocol. TCP establishes a connection between a sender and receiver before data can be sent. UDP does not establish a connection before sending data.
