The Transmission Control Protocol/Internet Protocol (TCP/IP)

Great Essays
Transmission Control Protocol/Internet Protocol (TCP/IP) are a suite of protocols designed for large-scale internetworks that span LAN and WAN environments. TCP/IP are communication protocols that are used to handle traffic on the internet and other networks. The two most important protocols are the Transmission Control Protocol (TCP) and the Internet Protocol (IP). These are today the standard networking protocols and were created from a synthesis of a number of earlier developments in the 1960’s and 1970’s. TCP/IP protocols were developed in the early 1970’s by scientists Vint Cerf and Bob Kahn. They developed the TCP/IP protocols as part of Defense Advanced Research Projects Agency (DARFA) which was part of a research network that had …show more content…
First, Jon Postel, who was one of the foremost people in the development of the early internet and TCP/IP, published a series of comments on the state of TCP. Postel’s comments led to the creation of TCP/IP architecture, and the splitting of TCP into TCP at the transport layer and IP at the network layer. Then in November, 1977, a three-network TCP/IP test was conducted between sites in the US, UK, and Norway. (CITE) 1978 saw version 3 of TCP as the process of dividing TCP into two parts began. Then in 1980 the first formal standard versions (version 4) of IP and TCP were created to be used in modern networks. In 1981 the Internet Protocol (IP) was introduced and described how to implement and addressing standard and route packets between interconnected networks. BY 1982 the US Department of Defense declared TCP/IP as the standard for all military computer networking. (CITE). Then in January 1983, ARPAnet started to require the use of TCP and IP protocols as a standard for all network traffic and essential communication. It was at this point that the protocols began to be known as the TCP/IP protocol …show more content…
The protocols also include provisions that permit it to function on most lower-level forms of technology, such as LANs, wireless LANs and WANs of various sorts. This enables people to mix and match a variety of different underlying networks and connect them all using TCP/IP.
• Scalability: The TCP/IP protocols have proven to be extremely scalable over the years. As the internet has grown from a few servers to millions of hosts, the core of TCP/IP is nearly the same as it was about 25 years ago. The only changes having been made are the ones required to support the growth of the internet and are done as a part of the TCP/IP development process.
• The Open Standards and Development Process: The standards used by TCP/IP are not exclusive, but freely available to the public. Also the process used to create the TCP/IP standards are freely available to the public. TCP/IP standards and protocols were developed and have been modified using the unique, democratic “RFC” process. This process allows anyone interested in TCP/IP protocols to provide input in regards to their development and helps ensure that the protocol suite is accepted worldwide.

    To fully understand how servers and clients are able to exchange information across the Internet we must understand the workings of the most widely used protocol used in computing. That protocol is the TCP/IP protocol and associated common set of rules for addressing. IP addresses The TCP/IP protocol suite uses an Internet address, or IP address, to identify each network interface on the network. Devices can have more that one interface connected to the network. Each interface must have a unique IP address that identifies that interface.…

    This process takes place through routers which switch the data to the required destination. Known as TCP/IP (Transmission Control Protocol/Internet Protocol), this process developed out of a necessity for a standardised method for different networks to communicate with each other (Rosenzwseig, 1998, p. 1536). Rosenzsweig (1998, p. 1539) claims the internet was primarily developed in the US, as the US military needed…

If we are creating small network it is easy to assign an IP address manually but if we want to develop a large network we can assign IP address with the help of DHCP server. DHCP server provides automatically IP address to all computers and other information such as default gateway and DNS server address to the computers.…

    January 1, 1983 saw the official deployment of TCP/IP as the new standard host protocol for ARPAnet (replacing the NCP protocol). The transition [RFC 801] from NCP to TCP/IP was a flag day event—all hosts were required to transfer over to TCP/IP as of that day. In the late 1980s, important extensions were made to TCP to implement host-based congestion control [Jacobson 1988]. The DNS, used to map between a human-readable Internet name (for example, gaia.cs.umass.edu) and its 32-bit…

    TCP/IP is the primary communication language or also known as the protocol of the Internet. When you are permitted first hand access to the Internet, your computer is provided with a copy of the TCP/IP program .It can also be used as a communications procedure in a secure network like an Internet or Extranet. TCP sends data in a form that appears to be transferred in a character-by-character fashion, rather than as separate packets. Next, we will be discussing the Importance of Protocols in Internet Services. Simultaneously millions of people around the world use the Internet and the Internet protocols are used to send data from one computer to another.…
