A Network Protocol is a group of rules accompanied by the network. Network protocols will be formalized requirements and plans composed of rules, procedures, and types that describe communication among a couple of devices over the network. The protocol can be described as an approach to rules that enable a couple of entities of a communication program to transfer information through any type of variety of a physical medium.

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. The main difference between the two protocols is that TCP uses a connection-oriented transport, while UDP uses a connectionless type of communication. When the TCP protocol is used, a special connection is opened up between two network devices, and the channel remains open to transmit data until it is closed.

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. Here we will be discussing these standard set of rules. Yes, we're talking about "protocols" which are set of rules that help in governing the way a particular technology will function for communication. There are different networks and network protocols, user's use while surfing.

Types of Network Protocols Explained with Functions

It is the foundation of any data exchange on the Web and it is a client-server protocol, which means requests are initiated by the recipient, usually the Web browser. A complete document is reconstructed from the different sub-documents fetched, for instance text, layout description, images, videos, scripts, and more. Clients and servers communicate by exchanging individual messages as opposed to a stream of data. The messages sent by the client, usually a Web browser, are called requests and the messages sent by the server as an answer are called responses. Designed in the early s, HTTP is an extensible protocol which has evolved over time. It is an application layer protocol that is sent over TCP , or over a TLS -encrypted TCP connection, though any reliable transport protocol could theoretically be used. Due to its extensibility, it is used to not only fetch hypertext documents, but also images and videos or to post content to servers, like with HTML form results.

In the era of Computer and Mobile technologies, computer network technology is growing at a very fast speed and frequency. Billions of electronic devices and gadgets are operating to make this happen. These devices are designed and manufactured by different manufacturers. They may have been developed using different hardware and software resources. Due to this, they are unable to establish a connection and communicate with each other for sharing data and other information. Hence, to resolve this problem, 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.

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.

Types of Internet Protocols

The functions of protocols are quite essential in the process of Networking. There are a number of protocols which exist and are used for various purposes. In fact, each of the protocol has been developed keeping in mind a particular situation or problem. Sometimes more than one protocols work together to achieve their task.

Types of Networking 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.

About the OLLC

Тридцатью метрами ниже горел купол шифровалки. Поликарбонатная крыша еще была цела, но под ее прозрачной оболочкой бушевало пламя. Внутри клубились тучи черного дыма. Все трое как завороженные смотрели на это зрелище, не лишенное какой-то потусторонней величественности. Фонтейн словно окаменел.

 - Qu'est-ce-que vous voulez. Ясно, подумал Беккер с улыбкой. Канадский француз. - Пожалуйста, уделите мне одну минуту. Беккер отлично говорил по-французски, тем не менее обратился к этому человеку на языке, который тот, как он надеялся, должен был знать хуже. Убедить абсолютно незнакомого человека отдать вам золотое кольцо скорее всего будет весьма непросто, поэтому Беккер хотел заручиться хотя бы одним преимуществом.

Джабба не шелохнулся. - Мы ищем цифровой ключ, черт его дери. А не альфа-группы. Ключ к шифру-убийце - это число. - Но, сэр, тут висячие строки. Танкадо - мастер высокого класса, он никогда не оставил бы висячие строки, тем более в таком количестве. Эти висячие строки, или сироты, обозначают лишние строки программы, никак не связанные с ее функцией.

Мы идем ко дну.

Сьюзан чувствовала, как кабина набирает скорость, двигаясь в сторону главного здания АНБ. Наконец она остановилась, и дверь открылась. Покашливая, Сьюзан неуверенно шагнула в темный коридор с цементными стенами. Она оказалась в тоннеле, очень узком, с низким потолком.

Теперь Сьюзан точно знала, зачем ее вызвал Стратмор. - Я, кажется, догадалась, - сказала.  - Вы хотите, чтобы я проникла в секретную базу данных ARA и установила личность Северной Дакоты.

When we think of the Internet we often think only of the World Wide Web.
