2 Introduction: The Internet is evolving. The majority of end-users perceive this evolution in the form of changes and updates to the software and networked applications that they are familiar with, or with the arrival of entirely new applications that change the way they communicate, do business, entertain themselves, and so on. Evolution is a constant feature throughout the network

Topic explanation: The begins with the development of electronic computers in the 1950s. Initial concepts of packet networking originated in several computer science laboratories in the United States, Great Britain, and France. The US Department of Defense awarded contracts as early as the 1960s for packet network systems, including the development of the ARPANET (which would become the first network to use the Internet Protocol.) The first message was sent over the ARPANET from computer science Professor Leonard Kleinrock's laboratory at University of , Los Angeles (UCLA) to the second network at Stanford Research Institute (SRI).

Packet switching networks such as ARPANET, NPL network, CYCLADES, , , and Telnet, were developed in the late 1960s and early 1970s using a variety of communications protocols. was the first to put theory into practice by

3 designing a packet-switched network at the National Physics Laboratory in the UK, the first of its kind in the world and the cornerstone for UK research for almost two decades. Following, ARPANET further led to the development of protocols for , in which multiple separate networks could be joined into a network of networks.

Access to the ARPANET was expanded in 1981 when the National Science Foundation (NSF) funded the Computer Science Network (CSNET). In 1982, the (TCP/IP) was introduced as the standard networking protocol on the ARPANET. In the early 1980s the NSF funded the establishment for national supercomputing centers at several universities, and provided interconnectivity in 1986 with the NSFNET project, which also created network access to the supercomputer sites in the United States from research and organizations. Commercial Internet service providers (ISPs) began to emerge in the late 1980s. The ARPANET was decommissioned in 1990. Private connections to the Internet by commercial entities became widespread quickly, and the NSFNET was decommissioned in 1995, removing the last restrictions on the use of the Internet to carry commercial traffic.

In the 1980s, the work of Tim Berners-Lee in the United Kingdom, on the , theorized the fact that protocols link hypertext documents into a working system, marking the beginning the modern Internet. Since the mid-1990s, the Internet has had a revolutionary impact on culture and commerce, including the rise of near-instant communication by electronic mail, instant messaging, voice over Internet Protocol (VoIP) calls, two-way interactive video calls, and the World Wide Web with its discussion forums, blogs, social networking, and online shopping sites. The research and education community continues to develop and use advanced networks such as NSF's very high speed Backbone Network Service (vBNS), , and National Lambda Rail. Increasing amounts of data are transmitted

4 at higher and higher speeds over fiber optic networks operating at 1- Gbit/s, 10-Gbit/s, or more. The Internet's takeover of the global communication landscape was almost instant in historical terms: it only communicated 1% of the information flowing through two-way networks in the year 1993, already 51% by 2000, and more than 97% of the telecommunicated information by 2007. Today the Internet continues to grow, driven by ever greater amounts of online information, commerce, entertainment, and social networking.

Conclusions: The evolution of information technology reached a turning point with the development of the Internet. The Internet was created for military purposes. Through the course of its development, researchers began finding other uses forthe network, and use of the technology spread worldwide. Access to the Internet today by individuals, businesses, and institutions alike has created a global market for Internet service and has spurned an increase in productivity in the technological communication field. Its evolution will surely continue with every passing day to become a more capable and useful tool.
