Chapter 1, Problem 1HA1
Explanation of Solution
Introduction:
Presently, the internet pervades everyone’s lives, delivering information to them no matter where they are.
The Internet is the worldwide system of interconnected
Generally, the Internet is a network of networks consisting of public, private, government, academic and business networks of local to global space, linked by wireless, optical and electronic networking technologies.
The Internet carries a wide range of information services and resources as the applications of the electronic mail, file sharing and telephony.
History of Internet:
- Creation of the agency “Advanced Research Projects Agency (ARPA)” in 1958 is the most important moment that led to the construction of the present day Internet.
- In 1962, ARPA and Massachusetts Institute of Technology (MIT) suggested to connect computer machines to keep an active communications network. This network later came to be known as ARPANET or ARPA network.
- Initially, ARPANET was created for defense purpose only.
- In 1965, data transmission was made possible with the help of Packet switching.
- In 1969, an Interface Message Processor (IMP) was developed and it is considered to be early form of routing device.
- In 1981, the first local area network was the Stanford University Network connecting workstations.
- In the same year, the National Science Foundation (NSF) expanded ARPANET to national computer science researchers.
- In 1983, ARPANET implemented the Transmission Control Protocol (TCP) separated the military network and assigned a subnet for public research...
