The internet is a worldwide network of computers connecting thousands and thousands of computers across the globe.It is formed by the joining of many smaller networks around the world to form the largest network in the world.
The computers of the Internet are connected through telephone lines,satellite links,modemand through many other means.
The Internet consists of following applications :
# World Wide Web
#Chatting
# Video Conferencing
# Searching for information
#Online Shopping and Trade
#Education and Research
Internet History -- One Page Summary
The conceptual foundation for creation of the Internet was largely created by three individuals and a research conference, each of which changed the way we thought about technology by accurately predicting its future:
In 1957, the Soviet Union launched the first satellite, Sputnik I, triggering US President Dwight Eisenhower to create the ARPA agency to regain the technological lead in the arms race. ARPA appointed J.C.R. Licklider to head the new IPTO organization with a mandate to further the research of the SAGE program and help protect the US against a space-based nuclear attack. Licklider evangelized within the IPTO about the potential benefits of a country-wide communications network, influencing his successors to hire Lawrence Robertsto implement his vision.
Roberts led development of the network, based on the new idea of packet switching invented by Paul Baran at RAND, and a few years later by Donald Davies at the UK National Physical Laboratory. A special computer called an Interface Message Processor was developed to realize the design, and the ARPANET went live in early October, 1969. The first communications were between Leonard Kleinrock's research center at the University of California at Los Angeles, and Douglas Engelbart's center at the Stanford Research Institute.
The first networking protocol used on the ARPANET was the Network Control Program. In 1983, it was replaced with the TCP/IP protocol invented Wby Robert Kahn, Vinton Cerf, and others, which quickly became the most widely used network protocol in the world.
In 1990, the ARPANET was retired and transferred to the NSFNET. The NSFNET was soon connected to the CSNET, which linked Universities around North America, and then to the EUnet, which connected research facilities in Europe. Thanks in part to the NSF's enlightened management, and fueled by the popularity of the web, the use of the Internet exploded after 1990, causing the US Government to transfer management to independent organizations starting in 1995.And here we are.

Experimental research design involves manipulating one or more variables in a controlled setting to observe the effect on the dependent variable. It allows researchers to establish cause-and-effect relationships by controlling for potential confounding variables. This design is characterized by random assignment of participants to different conditions and the use of control groups to minimize bias and increase the internal validity of the study.
