Data Communication

An operating system must support a wide variety of networking protocols in order to meet the needs of its users. The user will be able to identify and make sure that various systems and servers are running smoothly, also the user is will if the system is loaded or

Some of the networking basics are discussed below like TCP, UDP, TCP/IP, and OSI model.

Network protocol communications, network connections established by host computer, network routing information, information about computers

Our project focuses on the analysis of a network protocol and how it works. The network layer Oliveir Bonaventure explains as "providing a connection-less service. It identifies each (interface of a) host by using an IP address. "[4] Mainly this layer passes information between layers and provides a way to address them. The main goal to enable hosts to send packets of information containing up to 64 KB. An issue arises when information doesn't deliver to the correct destination. This issue is because there is no actual guarantee of the delivery. Also, the detection of errors isn't a guarantee during the transmission process. There is a common analogy for the network layer. "It's like a worldwide postal service providing an addressing and

The Internet layer is a group of protocols and specifications that are used to transport packets from the host across a network, the host specified by a network address (IP address)

This paper aims to include, classify and organize a range of protocols to deliver a comprehensive analysis. Variety of

Technologies related to internetworking is growing rapidly day by day. “A network is a group of connected, communicating devices such as computers and printers.” [1] When two or more networks exists and communicate with each other, it is known as an internet. We know, Internet is the most notable internet, which is composed of thousands of interconnected networks [1]. Any individual or any organization such as

Since the rapid increase of use of Internet, computer network technology has rapid growth. Now a day’s internet is used in almost every fields like governments, business and health care and schools etc. made the rapid development of the computer network technology.

A protocol is most simply defined as a standard. These standards define how computers are able to communicate with each other. These standards are defined in documents called Request for Comments( RFC ) which is a formal document from an organization known as the Internet Engineering Task Force( IETF ). These documents are made publicly available so that any program that needs to use these protocols are able to configure them properly so that it works with all other programs that make use of the same protocol. There are thousands of protocols that exist and many of them are very common and others are very seldom used. Some of the most common protocols are HTTP/HTTPS, FTP, SMTP, IMAP, POP3, SSH and DNS. Many of these are used almost every

Computer networking is the engineering discipline concerned with the communication between computer systems or devices. A computer network is any set of computers or devices connected to each other with the ability to exchange data. It is sometimes considered a sub-discipline of telecommunications, computer science, information technology and computer engineering since it relies heavily upon the theoretical and practical application of these scientific and engineering disciplines. There are three types of networks namely: Internet, intranet, and extranet.

In the 1960’s the government of the United States build a robust, fault tolerant communication via computer network but it was not the internet. There is not exact time or date when the internet came into human existence. USA companies such as National Science Foundation and other private businesses led to the worldwide funding of the development of new networking technology and the merger of main networks. Estimated 2.4billions people of the human population have use the internet service. Communications methods such as telephone music, film and television are being remodel by the internet giving birth to new service such as voice over internet protocol and internet protocol television. Newspaper, books and other publishing are adapting to website

Network Protocols – The network components and the protocols are used to interconnect the system to the routers, or bridges and so on.

Protocols is a set of rules that governs the communication and the use of the internet (networks). They follow the rules that is introduce by highest authority of the internet (world government); such as data transfer speed, cabling types and hardware us and so on. The protocol includes the programme requirements of the computer such as firewall, security programme (anti-virus), file sharing and more.

Internet Protocol (IP), User Datagram Protocol (UDP), and Transmission Control Protocol (TCP) are the basic tools for network communication. The name TCP/IP comes from two of the best-known protocols of the internet protocol suite, the Transmission Control Protocol and the Internet Protocol. With TCP/IP you can communicate over single networks or interconnected networks (Internet).

Communication plays a very important role in our daily life it has become a most compulsory thing to have at least a communication device per each person. It is now very significant to communicate with other people to finish work without travelling from one place to the other which takes a lot of time and money. Therefore, the appearance of fast and reliable communication is being inclined day by day. To perform these preferred levels of communication we need a network which can doing as a media between the communicators on either side. These networks from its beginning as a straight type with low reliability and speed, now after many involvements and creations of man developed as a communication network with no time delay and high reliability.
