First generation of computers

The First Generation

The first generation of computers, beginning around the end of World War

2, and continuing until around the year 1957, included computers that used

vacuum tubes, drum memories, and programming in machine code.

Computers at that time where mammoth machines that did not have the

power our present day desktop microcomputers.

In 1950, the first real-time, interactive computer was completed by a

design team at MIT. The "Whirlwind Computer," as it was called, was a

revamped U.S. Navy project for developing an aircraft simulator. The

Whirlwind used a cathode ray tube and a light gun to provide interactively.

The Whirlwind was linked to a series of radars and could identify unfriendly

aircraft and direct interceptor fighters to their projected locations. It was to

be the prototype for a network of computers and radar sites (SAGE) acting

as an important element of U.S. air defense for a quarter-century after 1958.

In 1951, the first commercially-available computer was delivered to the

Bureau of the Census by the Eckert Mauchly Computer Corporation. The

UNIVAC (Universal Automatic Computer) was the first computer which was

not a one-of-a-kind laboratory instrument. The UNIVAC became a

household word in 1952 when it was used on a televised newscast to project

the winner of the Eisenhower-Stevenson presidential race with stunning

accuracy. That same year Maurice V. Wilkes (developer of EDSAC) laid the

foundation for the concepts of microprogramming, which was to become the

guide for computer design and construction.

In 1954, the first general-purpose computer to be completely

transistorized was built at Bell Laboratories. TRADIC (Transistorized

Airborne Digital Computer) held 800 transistors and bettered its

predecessors by functioning well aboard airplanes.

In 1956, the first system for storing files to be accessed randomly was

completed. The RAMAC (Random-Access Method for Accounting and

Control) 305 could access any of 50 magnetic disks. It was capable of

storing 5 million characters, within a second. In 1962, the concept was

expanded with research in replaceable disk packs.
