Application And The Evolution Of Tcp Ip Protocol

But how does it work? The internet, based on the concept of “packet switching”, involves the travelling of small packets of data over one or more networks (Frenzel, 2013). This can be compared to “electronic postcards”, meaning that “a computer generates a piece of data and flings it into the net, just like the postal system, except 100 million times faster” (Cerf, 2013). This concept allows one computer to speak to many different computers around the network by sending out these “electronic postcards”. However, before these networks can work seamlessly together, they must use a common protocol, or set of rules for transmitting and receiving these packets of data. There are several protocols currently in use, including the OSI Model, the TCP/IP Model, UDP, HTTP, and FDP (Mitchell, 2014), but the most commonly used is Transmission Control Protocol/Internet Protocol (TCP/IP) (Gilmer, 2011). Even as early as 1977, TCP/IP was being used by other networks to link to ARPANET (Kozierok,

It is important to know the history of the internet. The internet is a worldwide network of computer systems that are connected to each other by cables (Howe, 2012). The internet first started out as a military experiment. In 1957, the Advanced Research Projects Agency (ARPA) was created by the United States department of Defense (Computer History Museum, 2004). The project was started after the Russians launched a satellite into space for communication reasons. The satellite was called SPUTNIK (Computer History Museum, 2004). It was rumored that President Eisenhower got worried and decided to get the United States to launch its own satellite. They recruited Dr. Joseph C. Licklider of MIT, was made head of the Information Processing Techniques Office (IPTO)(Computer History Museum, 2004). Their purpose of the project was to focus on improving the military use of computer information.

TCP/IP is a protocol which transfers data across a network. It allows two different computers to communicate well even if they use different codes. Putting both computers into a new common code language which both computers

Internet Protocol version 4 (IPv4) IPv4 is a connectionless protocol for use on packet-switched networks. It is the fourth version of the Internet Protocol (IP), that is one of the core protocols of standards-based internetworking methods in the Internet. It was the first version deployed for production in the ARPANET in 1983. It still used to routing most Internet traffic today, eventhough we have the next version of it,IPv6.

Transmission Control Protocol/Internet Protocol (TCP/IP) are the basic communication protocols, which were designed to provide low level support for internetworking. This term is generally also used to refer to a more generalised collection of protocols developed by the internet community and U.S. Department of Defence.

The internet layer is built up of four core protocols: IP, IGMP, ICMP and ARP. Internet protocol (IP) is responsible for routing, IP addressing and breakdown/reassembly of data packets, address resolution protocol (ARP) is responsible for mapping an IP address to a device on the local network, internet control message protocol (ICMP) provides diagnostic information and error reports on lost packets, internet group management protocol (IGMP) controls who receives IP datagrams in a single transmission. The transport layer is built up of two core protocols: TCP and UDP. Transmission control protocol (TCP) sequences and acknowledges packets sent and their recovery when lost in transmission allowing the computer to make and maintain network conversations where applications exchange data, defined as a connection-oriented protocol meaning the connection is maintained until the programs has finished exchanging data. User datagram protocol (UDP) This is used to transfer small amounts of data when the use of error correction isn’t needed increasing the speed of the transmission, common in multi-player video games as the user will not need to receive packets of past events in the game so the error correction featured in (TCP) would be

The Internet is, quite literally, a network of networks. It is comprised of ten thousands of interconnected networks spanning the globe. The computers that form the Internet range from huge mainframes in research establishments to modest PCs in people's homes and offices. Despite the recent hype, the Internet is not a new phenomenon. Its roots lie in a collection of computers that were linked together in the 1970s to form the US Department of Defense's communications systems. Fearing the consequences of nuclear attack, there was no central computer holding vast amounts of data, rather the information was dispersed across thousands of machines. A set of rules, of protocols, known as TCP/IP was

The two authors follow the story from the conception of the idea of "packet switching" in the early 1960s to the creation and development of the Internet. We see how one idea led to another and how the intelligent people around the circumstances influenced the developments.

network (ARPANET) meant to promote the sharing of super-computers amongst researchers in the United States.” (Kristula, pg 68). Through the next couple years there were talks of about how this network could come into the cooperate world. In 1969 researchers at four US campuses created the first hosts of the ARPANET. They connected the Stanford Research Institute, UCLA, UC Santa Barbara, and the University of Utah. The ARPANET was a success from the very beginning. Although originally designed to allow scientists to share data and access remote computers, email quickly became the most popular application. The ARPANET became a high-speed digital post office as people use it to collaborate on research projects and discuss topics of various interests. In 1971 the ARPANET grows to 23 hosts connecting universities and government research centers around the country. In 1972, the Inter-Networking Working Group becomes

The TCP/IP protocols are the heart and soul of the Internet, and they describe the fundamental rules that govern all communications in the network. The original address system of the Internet is Internet Protocol version 4 (IPv4). The Internet Engineering Task Force (IETF) developed IPv6 to deal with the long-anticipated problem of IPv4 address exhaustion. However, IPv6 is not foreseen to supplant IPv4 instantaneously.

Perhaps one of the greatest inventions of out time is the Internet. Without a doubt, the net has had a profound effect on almost every aspect of our lives. The formation of the Internet has changed the way we do business, communicate, entertain, retrieve information, and even educate ourselves. Nevertheless, the Internet might have never materialized if it had not been for some innovated thinkers from the Advanced Research Project Agency, who created "ARPANET." In collaboration with several educational and research institutions, the agency created the packet-switching technologies that form the basis of the Internet today.

Internet: Global network of networks using universal standards to connect millions of different networks (Kenneth C Laudon and Jane P Laudon., 2010).

Over the next 10 years, we will see a change in technology, and the Internet. Things will continue to progress, and fundamental changes will easily be defined. Technologies have revolutionized how people spread and consume information; these changes will redefine who we are as consumers, merchants, and individuals. With the expansion of computers and the Internet connectivity, people are able to share more of their lives with family and friends. Technology has offered the world so many different services, which include emailing, instant messaging, search engines, blogs, and Wikipedia. These services have changed the way we communicate with others, our knowledge, and the way we conduct business. With the increasing usage of the Internet, developers continue to find ways to improve technology and the way we utilize the Internet. Technology has a wide range of different aspects and concepts, which includes protocols. There has to be rules, and objectives in any and everything we do, and protocols governs communications, errors, detections, messages, and speed. There are three technology concepts behind the Internet, and they are packet switching, Transmission Control Protocol/Internet Protocol (TCP/IP) communications

The two TCP/IP transport layer protocols (TCP and UDP), are very crucial for the smooth operation of network services for both the computer applications and application layer protocols such as HTTP, FTP, SMTP and Telnet. These two transport layer protocols TCP and UDP execute these services via the employment of IP. They use IP in the efficient routing of packets to their respective destination networks (Steinke,2001).The TCP is further noted by Steinke (2001) to be responsible for the provision of a reliable and yet connection-oriented byte-stream packet delivery while its counterpart UDP is noted to be responsible for the provision of a connectionless but rather unreliable packet delivery. In this paper we explain the work of the two TCP/IP transport layer protocols (TCP and UDP). In addition, describe how TCP and UDP manage key functions such as reliability, port addressing, and segmentation.

The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (TCP/IP) to serve billions of users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless and optical networking technologies. The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents of the World Wide Web (WWW) and the infrastructure to support electronic mail.
