Question: What Are Protocols And Types Of Protocols?

What are layer protocols?

A protocol is a set of rules and conventions that describe how information is to be exchanged between two entities.

Networking tasks often require more than one protocol to perform a task, such as file transfer.

A set of protocols layered in this way is called a protocol stack.


Why are protocols needed?

A network protocol includes the pre-defined rules and conventions for communication between network and devices connected. … Additionally, there are protocols for message acknowledgment and data compression too. It also enables the establishment of reliable and high-performing network communication.

What is the use of UDP protocol?

UDP (User Datagram Protocol) is a connectionless protocol of the internet protocol family that operates at the transport layer and was specified in 1980 in RFC (Request for Comments) 768. As a lean and almost delay-free alternative to TCP, UDP is used for the fast transmission of data packets in IP networks.

What is protocol give example?

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

What is TCP and UDP?

As we know that both TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) are the most widely used Internet protocols among which TCP is connection oriented − once a connection is established, data can be sent bidirectional. UDP is a simpler, connectionless Internet protocol.

What is protocol 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 protocol and standard?

A protocol is a particular set of rules for having a conversation between two computers to convey a specific set of information. A standard (and in the networking arena, many protocols are standards) is a document that specifies something that has the overwhelming support and agreement of the standards making body.

What are different types of protocols?

What is protocol and how many types of protocol?

Generally speaking, networks have three types of protocols — communication, such as Ethernet; management, such as the Simple Mail Transfer Protocol (SMTP); and security, such as Secure Shell (SSH).

What are network protocols?

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.
