Computers were….
Sigma -7

Revolutionary ideas
• Computers could be PROBLEM SOLVING
• Computers could perform more than one task
• (Batch sharing)…. (computer punch card
below)

Major developments
• The idea of “time sharing”
• The idea of man-computer symbosis

Early bits of importance
• What would they share?
• Different software for every host computer

Even crazier- and more fundamental
1962: JCR Licklider at MIT – world-wide
computer network where once computer linked
to another, with anyone who could connect to
anyone else, anywhere….

Decentralization of nodes
Redundant networks
No central node*

ARPANET!!!!! (1962-66ish)

Packet-Switching (~1964/5/6)

First time talkers
-1965: TX-2 Computer at MIT talks to Q-32
Mainframe at RAND in LA
-Insert your favorite overlapping node/network
of UCLA/UTAH/STANFORD/UCSB
- Phone lines? Radio lines? Need better wires!!!

HOST-IMP (late 1960s)

EMAIL: 1968/1972
• An accident
• HUGE
• THERE WAS NO PROTOCOL. AT ALL.

TCP/IP: OPEN ARCHITECHTURE
SMTP; FTP; HTTP
DATA-divides into packets, puts back
together, checks if they are ok
(IP) – virtual address; packets called
datagrams
Ethernet: gets the packets and
sends/receives them

You don’t need an IMP, or a HOST
