The Internet Protocol Suite is the set of communications protocols used for the Internet and other similar networks. It is commonly also known as TCP/IP named from two of the most important protocols in it: the Transmission Control Protocol (TCP) and the Internet Protocol (IP)‚ which were the first two networking protocols defined in this standard. Modern IP networking represents a synthesis of several developments that began to evolve in the 1960s and 1970s‚ namely the Internet and local area networks

use the internet‚ yet there probably is only a small percentage who understands how the internet sends information or where the technology to send the data originated. (Miniwatts Marketing Group‚ 2008) In 1973‚ a paper titled "A Partial Specification of an International Transmission Protocol" was written by Vint Cerf. This paper included a system for more efficiently transmitting information across a network and also included references to TCP or transmission control protocol. In 1973‚ Robert Kahn

USER DATAGRAM PROTOCOL(UDP): The User Datagram Protocol(UDP) is called a connectionless‚ unreliable transport protocol. It does not add anything to the services of IP except to provide process to process communication instead of host to host communication. USER DATAGRAM: UDP packets‚ called user datagrams‚ have a fixed size header of 8 bytes. The below diagram shows the format of a user datagram.

in TCP/IP At first glance‚ TCP/IP (Transmission Control Protocol/Internet Protocol) may seem baffling. Many other protocols‚ such as NetBEUI and IPX/SPX‚ require no configuration. TCP/IP is different. Due to the seemingly endless number of options that you can configure within TCP/IP‚ many people become intimidated at first. In reality‚ however‚ TCP/IP isn ’t very difficult‚ but you have to gain some understanding of what you ’re configuring. So‚ I ’m going to give you a crash course in TCP/IP.

TCP/IP for IP version 4 (IPv4) is a networking protocol suite that Microsoft Windows uses to communicate over the internet with other computers. It interacts with Windows naming services like DNS and security technologies‚ such as IPsec primarily‚ as these help facilitate the successful and secure transfer of IP packets between machines. Ideally‚ TCP/IP is used whenever Windows-based computers communicate over networks. This subject describes the components of the TCP/IP Protocol Suite‚ the protocol

What is the purpose of an OSI model? The purpose of an OSI model is a standard that was created for networks to share information. This standard governs the way information is transmitted over different networks. The model also sets guidelines to those in the manufacturing industry that create and develop software and hardware that are all compatible with each other. This paper will discuss and describe the 7 layers of the Open System Interconnection model (OSI model) and the layers of the Transport

A: /home/guest/ /home/guest/fangyuliu Exercise 3 LAB REPORT Q:Is the Internet service daemon‚ xinetd‚ started in your system? Is inetd started in your system? Why? A:xinetd(extended Internet daemon) is started in my system rather than inetd (internet service daemon). Both of them are super-server daemon started only under request. Because xinetd is more secure than

meeting in Sydney in March 1977. OSI was hence an industry effort‚ attempting to get industry participants to agree on common network standards to provide multi-vendor interoperability. It was common for large networks to support multiple network protocol suites‚ with many devices unable to interoperate with other devices because of a lack of common protocols. However‚ while OSI developed its networking standards‚ TCP/IP came into widespread use on multivendor networks for internetworking; while on
