TCP/IP Ports and Protocols

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.

Network Protocols are a set of rules governing exchange of information in an easy, reliable and secure way. Before we discuss the most common protocols used to transmit and receive data over a network, we need to understand how a network is logically organized or designed. OSI model is not a network architecture because it does not specify the exact services and protocols for each layer. It simply tells what each layer should do by defining its input and output data. It is up to network architects to implement the layers according to their needs and resources available.

How do Common Networking Protocols Function

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. The protocol identifies the rules, syntax, semantics as well as, synchronization of communication as well as, feasible error managing methods. In this article, we will discuss the different types of networking 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. However, just an overview of these protocols is not necessary to manage the process of networking.

Lists of network protocols

Network protocols are the languages and rules used during communication in a computer network. There are two major transport protocols namely;. Therefore, TCP is used for transferring most types of data such as webpages and files over the Internet. For this reason, the UDP protocol is typically used for streaming media.

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.

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.

Introduction to Types of Networking Protocols

Тот же, кто перехватывал такое сообщение, видел на экране лишь маловразумительную абракадабру. Расшифровать сообщение можно было лишь введя специальный ключ - секретный набор знаков, действующий как ПИН-код в банкомате. Ключ, как правило, был довольно длинным и сложным и содержал всю необходимую информацию об алгоритме кодирования, задействуя математические операции, необходимые для воссоздания исходного текста. Теперь пользователь мог посылать конфиденциальные сообщения: ведь если даже его послание перехватывалось, расшифровать его могли лишь те, кто знал ключ-пароль. АНБ сразу же осознало, что возникла кризисная ситуация.

Пальцы совсем онемели. Беккер посмотрел вниз, на свои ноги. До апельсиновых деревьев не меньше ста метров. Никаких шансов. Боль в боку усилилась. Сверху слышался гулкий звук шагов, спешащих вниз по лестнице.

Новых сообщений не. Сьюзан прочитала их. Стратмор в отчаянии нажал на кнопку просмотра. ОБЪЕКТ: ЭНСЕЙ ТАНКАДО - ЛИКВИДИРОВАН ОБЪЕКТ: ПЬЕР КЛУШАР - ЛИКВИДИРОВАН ОБЪЕКТ: ГАНС ХУБЕР - ЛИКВИДИРОВАН ОБЪЕКТ: РОСИО ЕВА ГРАНАДА - ЛИКВИДИРОВАНА… Список на этом не заканчивался, и Стратмора охватил ужас. Я смогу ей объяснить.

 Я торговец ювелирными изделиями. Жемчугами из Майорки. - Неужели из Майорки. Вы, должно быть, много путешествуете. Голос болезненно кашлянул.

Стратмор и его высокопоставленные посетители попадали в шифровалку и уходили незаметно для остальных сотрудников.

Голос болезненно кашлянул. - Да. Немало. - В Севилью - по делам? - настаивал Ролдан. Ясно, конечно, что это никакой не полицейский, это Клиент с большой буквы.

Он неохотно выполз из-под компьютера. - Побойся Бога, Мидж. Я же сказал тебе… - Но это была не Мидж. Джабба удивленно заморгал.  - Соши.

Below, we take a look at these protocols, provides a basic description of their function, and lists the port numbers that they are commonly associated with.
