What computers were available in 1973?
The Xerox Alto, developed at Xerox PARC in 1973, was the first computer to use a mouse, the desktop metaphor, and a graphical user interface (GUI), concepts first introduced by Douglas Engelbart while at International. It was the first example of what would today be recognized as a complete personal computer.
What was the first personal computer PC made in the 1970s called?
From hobby computers to Apple A small firm named MITS made the first personal computer, the Altair. This computer, which used Intel Corporation’s 8080 microprocessor, was developed in 1974. Though the Altair was popular among computer hobbyists, its commercial appeal was limited.
How many computers were there in 1973?
A map published by the Advanced Research Projects Agency for the ARPANET shows the system had just 42 computers connected to 36 nodes in September 1973.
What is the name of the first personal machine created invented in 1973?
At Xerox PARC, Thacker led the project that developed the Alto, the first personal computer, in 1973. Alto used a bitmap display in which everything on the computer screen was, in effect, a picture and had a graphical user interface in which programs were shown in windows that could be manipulated by using a mouse.
What invention was made in 1973?
1973 was the year the Xerox Alto, the first cell phone call, TCP, Ethernet, and fiber optics were created. Together, all of those technologies have, in combination, informed the world we’re in today.

Who invented the Internet in 1973?
Something had to be done — and this is where two very bright ARPA researchers by the name of Robert Kahn and Vint Cerf came in. In 1973, the pair devised a new communication architecture with a universal set of rules that essentially allowed computer networks to speak the same language.
