A protocol is a standard set of rules that allow electronic devices to communicate with each other. These rules include what type of data may be transmitted, what commands are used to send and receive data, and how data transfers are confirmed. You can think of a protocol as a spoken language.

A Network Protocol is a group of rules accompanied by the network.

Chapter 2: Protocol

The Internet Protocol IP is the principal communications protocol in the Internet protocol suite for relaying datagrams across network boundaries. Its routing function enables internetworking , and essentially establishes the Internet. IP has the task of delivering packets from the source host to the destination host solely based on the IP addresses in the packet headers. For this purpose, IP defines packet structures that encapsulate the data to be delivered. It also defines addressing methods that are used to label the datagram with source and destination information. Historically, IP was the connectionless datagram service in the original Transmission Control Program introduced by Vint Cerf and Bob Kahn in , which was complemented by a connection-oriented service that became the basis for the Transmission Control Protocol TCP. Its successor is Internet Protocol Version 6 IPv6 , which has been in increasing deployment on the public Internet since c.

Protocol Definition: It is a digital language through which we communicate with others on the Internet. By adopting these rules, two devices can communicate with each other and can interchange information. Each protocol is defined in different terms and different use with unique name. Message travel from sender to receiver via a medium The medium is the physical path over which a message travels using a protocol. All data of protocols are stored in binary information. Protocol language is a mixture of bits, characters, integers, etc.

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. Network protocols are the reason you can easily communicate with people all over the world, and thus play a critical role in modern digital communications. Neither local area networks LAN nor wide area networks WAN could function the way they do today without the use of network protocols. Network protocols take large-scale processes and break them down into small, specific tasks or functions.

Types of Networking 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. Protocols may be implemented by hardware , software , or a combination of both. Communicating systems use well-defined formats for exchanging various messages. Each message has an exact meaning intended to elicit a response from a range of possible responses pre-determined for that particular situation.


simpler protocols, requiring only a few packets to complete its entire opera- tion. ARP (RFC ) will look at these different types of packets and what they do.


Types of Network Protocols and Their Uses

When we think of the Internet we often think only of the World Wide Web. The Web is one of several ways to retrieve information from the Internet. These different types of Internet connections are known as protocols.

This tutorial explains types of network protocols and their functions in details. Understanding these basic network protocols with functions will help you in managing network effectively. Learn how the most common types of network protocols works in computer network.

Types of Network Protocols Explained with Functions

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. Many different types of network protocols and standards are required to ensure that your computer no matter which operating system, network card, or application you are using can communicate with another computer located on the next desk or half-way around the world. The complexity of these layers is beyond the scope of this tutorial; however, they can be simplified into four layers to help identify some of the protocols with which you should be familiar see fig 1. Figure 1 illustrates how some of the major protocols would correlate to the OSI model in order to communicate via the Internet. In this model, there are four layers, including:. The physical layer of the network focuses on hardware elements, such as cables, repeaters, and network interface cards.

In the world of technology, there are vast numbers of users' communicating with different devices in different languages. That also includes many ways in which they transmit data along with the different software they implement. So, communicating worldwide will not be possible if there were no fixed 'standards' that will govern the way user communicates for data as well as the way our devices treat those data.

Это ты, приятель? - Он почувствовал, как рука незнакомца проскользнула к его бумажнику, чуть ослабив хватку.  - Эдди! - крикнул.  - Хватит валять дурака. Какой-то тип разыскивал Меган. Человек не выпускал его из рук. - Да хватит тебе, Эдди! - Но, посмотрев в зеркало, он убедился, что это вовсе не его закадычный дружок. Лицо в шрамах и следах оспы.

 - Панк снова сплюнул в проход.  - Чтоб мы не надоедали. - Значит, я не могу сойти. Парень захохотал. - Доедешь до конечной остановки, приятель. Через пять минут автобус, подпрыгивая, несся по темной сельской дороге.

 Действуй своим маячком очень осторожно, - сказал Стратмор.  - Если Северная Дакота заподозрит, что мы его ищем, он начнет паниковать и исчезнет вместе с паролем, так что никакая штурмовая группа до него не доберется. - Все произойдет, как булавочный укол, - заверила его Сьюзан.  - В тот момент, когда обнаружится его счет, маяк самоуничтожится. Танкадо даже не узнает, что мы побывали у него в гостях. - Спасибо, - устало кивнул коммандер.

Человек, к которому он направил Росио. Странно, подумал он, что сегодня вечером уже второй человек интересуется этим немцем. - Мистер Густафсон? - не удержался от смешка Ролдан.  - Ну. Я хорошо его знаю. Если вы принесете мне его паспорт, я позабочусь, чтобы он его получил.

Он был из другого теста - не их фирменной закваски. Она с самого начала возражала против его кандидатуры, но АНБ посчитало, что другого выхода. Хейл появился в порядке возмещения ущерба.

Повернувшись, она увидела, как за стеной, в шифровалке, Чатрукьян что-то говорит Хейлу. Понятно, домой он так и не ушел и теперь в панике пытается что-то внушить Хейлу. Она понимала, что это больше не имеет значения: Хейл и без того знал все, что можно было знать. Мне нужно доложить об этом Стратмору, - подумала она, - и как можно скорее.
