What Is Protocol And Explain Its Types?

Protocol Definition: It is

a digital language through which we communicate with others on the Internet

. protocol meaning is that it a set of mutually accepted and implemented rules at both ends of the communications channel for the proper exchange of information. … All data of protocols are stored in binary information.

What is protocol and types?

There are three main types of network protocols. These include

network management protocols

, network communication protocols and network security protocols: Communication protocols include basic data communication tools like TCP/IP and HTTP. Security protocols include HTTPS, SFTP, and SSL.

What is protocol and explain?

Protocol, in computer science,

a set of rules or procedures for transmitting data between electronic devices, such as computers

. In order for computers to exchange information, there must be a preexisting agreement as to how the information will be structured and how each side will send and receive it.

What is communication protocol and its types?

A communication protocol is

a system of rules that allows 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 is a protocol in computer?

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 are the 4 types of protocol?

• Transmission Control Protocol (TCP)
• Internet Protocol (IP)
• User Datagram Protocol (UDP)
• Post office Protocol (POP)
• Simple mail transport Protocol (SMTP)
• File Transfer Protocol (FTP)
• Hyper Text Transfer Protocol (HTTP)
• Hyper Text Transfer Protocol Secure (HTTPS)

What is protocol give 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).

Why do we need protocols?

Protocols provide us

with a medium and set of rules to establish communication between different devices for the exchange of data and other services

. Protocols are needed in every field like society, science & technology, Data Communication, media, etc.

What is IP protocol?

Internet Protocol (IP) –

a set of rules that dictate how data should be delivered over the public network (Internet)

. Often works in conjunction with the transmission control protocol (TCP), which divides traffic into packets for efficient transport through the Internet; together they are referred to as TCP/IP.

What is Telnet protocol?

The Telnet Protocol (TELNET)

provides a standard method for terminal devices and terminal-oriented processes to interface

. TELNET is commonly used by terminal emulation programs that allow you to log into a remote host. … TCP/IP implements TELNET in the tn, telnet, or tn3270 user commands.

What are the elements of communication protocol?

A protocol is a set of rules that govern data communications. It defines what is communicated, how it is communicated, and when it is communicated. The key elements of a protocol are

syntax, semantics, and timing

.

What is communication protocol give three examples?

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).

Is UDP an IP?

TCP and UDP are part of the

TCP/IP protocol suite

, which includes a number of protocols for carrying out network communications. UDP characteristics include the following: It is a connectionless protocol.

What is the most important protocol?

• Address Resolution Protocol (ARP) ARP is a protocol used in the TCP/IP stack to assist in mapping Layer 2 MAC addresses into IP addresses. …
• Spanning Tree Protocol (STP) …
• IEEE 802.1Q. …

Which protocol is used in Session layer?

What are two features of protocols used?

TCP mechanisms

retransmit data

when an acknowledgment is not received from the destination system within a set period of time. The same Transport Layer source port is used for all of the tabs opened at the same time within a web browser.
