Process Application Layer. Defines protocols for node-to-node application communication and also controls user interface specifications. Consists of a set of services that provide ubiquitous access to all types of networks.

Network protocols are the languages and rules used during communication in a computer network. There are two major transport protocols namely;.

TCP/IP vs OSI Model: What's the Difference?

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.

The OSI Model is a logical and conceptual model that defines network communication used by systems open to interconnection and communication with other systems. The Open System Interconnection OSI Model also defines a logical network and effectively describes computer packet transfer by using various layers of protocols. In this TCP Model vs. It helps you to create a virtual network when multiple computer networks are connected together. It is specifically designed as a model to offer highly reliable and end-to-end byte stream over an unreliable internetwork. In , an Experimental Packet Switched System in the UK identified the requirement for defining the higher-level protocols. In the year , the OSI model was initially intended to be a detailed specification of actual interfaces.

List of network protocols (OSI model)

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.

This article lists protocols , categorized by the nearest layer in the Open Systems Interconnection model. This list is not exclusive to only the OSI protocol family. From Wikipedia, the free encyclopedia. Wikipedia list article.

The OSI Model and Network Protocols

There are the seven OSI layers. Each layer has different functions. A list of seven layers are given below:.

Chapter 2: Protocol

И, что, на взгляд Хейла, было еще хуже, влюбилась в университетского профессора, который к тому же зарабатывал сущие гроши. Очень жаль, если она истратит свой превосходный генетический заряд, произведя потомство от этого выродка, - а ведь могла бы предпочесть его, Грега. У нас были бы красивые дети, - подумал. - Чем ты занята? - спросил Хейл, пробуя иной подход. Сьюзан ничего не ответила.

Кабинет номер 9А197. Директорские апартаменты. В этот субботний вечер в Коридоре красного дерева было пусто, все служащие давно разошлись по домам, чтобы предаться излюбленным развлечениям влиятельных людей. Хотя Бринкерхофф всегда мечтал о настоящей карьере в агентстве, он вынужден был довольствоваться положением личного помощника - бюрократическим тупиком, в который его загнала политическая крысиная возня. Тот факт, что он работал рядом с самым влиятельным человеком во всем американском разведывательном сообществе, служил ему малым утешением.

Беккер был на седьмом небе. Кольцо у нее, сказал он. Наконец-то.

Все здесь напоминало зловещую декорацию к голливудскому фильму ужасов. В воздухе стоял тяжелый запах мочи. Лампочки в конце коридора не горели, и на протяжении последних двадцати метров можно было различать только смутные силуэты. Женщина с кровотечением… плачущая молодая пара… молящаяся маленькая девочка.

 Но вы же не знали.
