Answer 1

Computer networks and its development

Sno	Period	Method	History
1	Late 1950	SAGE (Semi-Automatic Ground Environment)	It was used at U.S Military Radar system.
2	1960	SABRE(Semi-Automatic Business Research Envi­ronment)	At Commercial Airline Reservation system online connected with two main frame computers.
		Packet switching	Packet switching was developed by Paul Baran and Donald De­vices NPL network (National Physical Laboratory ) at united kingdom local area network (LAN) using line speed of 768kbit/s
3	1963	Intergalactic Computer network	The intergalactic Computer network was sent by J.C.RLicklider
4	1965	Telephone switch	At first widely used Telephone switch was introduced by Western Electric
5	1966	Wide Area Network(WAN)	An experimental paper on has been published by Thomas Marill Lawrence G.Roberts published in the area of time-sharing
6	1969­ 1970	ARPANET	First In 1969, four nodes of ARPANET were connected between four universities
7	1972	X.25 TCP/IP	Using X.25 as commercial services were deployed then was using infrastructure for expanding TCP/IP networks.
8	1973	Hosts	CYCLADES was the first for making hosts which is responsible for reliable delivery of data
9	1973­ 1979	Ethernet	A memo at Xerox PARC was written by Robert Metcalfe describing Ethernet in 1973. Aloha based networking system which was developed in the 1960s In July 1976 the paper published “Ethernet: Distributed Packet Switching for Local Computer Networks” by Robert Metcalfe and David Boggs. Collaborated on many patients received in 1977 and 1978. Robert Metcalfe pursued making on the open standard in 1979.
10	1976	ARCNET	ARCNET was created by John Murphy of Datapoint corporation in 1976
11	1995	NEW FIBRE OPTIC CA­BLES	The speed capacity of transmission for Ethernet was slightly elevated from 10 Mbit/s to 100Mbit/sat 1995. Frequently, the highest speeds up to 100 Gbit/s were appended (still 2016).
