What is protocol architecture

What is a protocol in network architecture?

Finally a protocol is a specification of how information is actually transfered at a layer from a sender to a receiver. A protocol will pack the data into Protocol Data Units (PDU).

What is the need for protocol architecture?

THE NEED FOR A PROTOCOL ARCHITECTURE When computers, terminals, and/or other data processing devices exchange data, the procedures involved can be quite complex. Consider, for example, the transfer of a file between two computers.

What is the difference between protocol and architecture?

Protocols define how diverse modules interact, and architecture defines how sets of protocols are organized. Architecture usually involves specification of protocols (rules of interaction) more than modules (which obey protocols ).

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 are the types of protocol?

Below are the different types of Networking Protocols. HTTP or HTTPs. This stands for Hypertext Transfer Protocol or Hypertext Transfer Protocol (secure). FTP (File Transfer Protocol ) Email Protocols ( POP3 , IMAP , SMTP ) TCP( Transmission Control Protocol ) and UDP ( User Datagram Protocol )

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.

Why are protocols necessary in communication?

Communication Protocols : Standard rules are needed to transfer data over the internet, so that both senders and receivers can understand each other’s message. These rules are defined by communication protocols in the internet world.

What are some advantages to layering as seen in the TCP IP architecture?

The various advantages of layering in tcp / ip are: 1.It provides scalability and flexibility to the model. 3.It allows multiple applications to reuse the components which ensures saving the cost. 4.It allows various teams to work on different part of applications.

What’s a protocol stack?

The protocol stack or network stack is an implementation of a computer networking protocol suite or protocol family. Some of these terms are used interchangeably but strictly speaking, the suite is the definition of the communication protocols , and the stack is the software implementation of them.

Is rest a protocol?

REST is web standards based architecture and uses HTTP Protocol . It revolves around resource where every component is a resource and a resource is accessed by a common interface using HTTP standard methods. REST uses various representation to represent a resource like text, JSON, XML.

Why REST is not a protocol?

Unlike SOAP-based web services, there is no “official” standard for RESTful web APIs. This is because REST is an architectural style, while SOAP is a protocol . REST is not a standard in itself, but RESTful implementations make use of standards, such as HTTP, URI, JSON, and XML.

What are standards and protocols?

Protocols and standards make networks work together. Protocols make it possible for the various components of a network to communicate with each other, and standards make it possible for different manufacturers’ network components to work together.

What is protocol in simple words?

English Language Learners Definition of protocol : a system of rules that explain the correct conduct and procedures to be followed in formal situations. : a plan for a scientific experiment or for medical treatment. formal : a document that describes the details of a treaty or formal agreement between countries.

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 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.
