Slide 31: Bits of History.. • September 1940George Stibitz used a teletype machine to send instructions for a problem set from his Model K at Dartmouth College in New Hampshire to his Complex Number Calculator in New York and received results back by the same means. >> 0 >> 1 >> 2 >> 3 >> 4 >>
Slide 32: Bits of History.. • In 1962, J.C.R. Licklider was hired and developed a working group he called the "Intergalactic Network", a precursor to the ARPANet (Advanced Research Projects Agency) >> 0 >> 1 >> 2 >> 3 >> 4 >>
Slide 33: Bit of History.. • In 1964, researchers at Dartmouth developed the Dartmouth Time Sharing System for distributed users of large computer systems. DTSS was the first large-scale time-sharing system to be implemented successfully >> 0 >> 1 >> 2 >> 3 >> 4 >>
Slide 34: Bits of History… • The same year, at MIT, a research group supported by General Electric and Bell Labs used a computer (DEC's PDP-8) to route and manage telephone connections. >> 0 >> 1 >> 2 >> 3 >> 4 >>
Slide 35: Bits of History… • Throughout the 1960s Leonard Kleinrock, Paul Baran and Donald Davies independently conceptualized and developed network systems which used datagrams or packets that could be used in a packet switched network between computer systems. >> 0 >> 1 >> 2 >> 3 >> 4 >>
Slide 36: Bits of History… • 1965 Thomas Merrill and Lawrence G. Roberts created the first wide area network(WAN) • The first widely used PSTN (public switched telephone network) switch that used true computer control was the Western Electric 1ESS switch, introduced in 1965. >> 0 >> 1 >> 2 >> 3 >> 4 >>
Slide 37: Bits of History… • In 1969 the University of California at Los Angeles, SRI (in Stanford), University of California at Santa Barbara, and the University of Utah were connected as the beginning of the ARPANet network using 50 kbit/s circuits. Commercial services using X.25, an alternative architecture to the TCP/IP suite, were deployed in 1972. >> 0 >> 1 >> 2 >> 3 >> 4 >>
Slide 38: Bits of History… • Computer networks, and the technologies needed to connect and communicate through and between them, continue to drive computer hardware, software, and peripherals industries. This expansion is mirrored by growth in the numbers and types of users of networks from the researcher to the home user. >> 0 >> 1 >> 2 >> 3 >> 4 >>
Slide 39: Bits of History… • Today, computer networks are the core of modern communication. • All modern aspects of the PSTN are computer-controlled • Telephony increasingly runs over the Internet Protocol, >> 0 >> 1 >> 2 >> 3 >> 4 >>
