History - First generation (1951-58)

IT Evolution | Timeline

Information technology evolution

Hardware

Vacuum Tube

Work on the transistor began, fuelled by the Cold war and the space program

The end of the era saw the development of the integrated circuit.

1955 IBM 705 series introduced

Software

Software evolved through 1st, 2nd and 3rd Generations;

First generation - Machine Language.

Instructions as the computer works with them, as binary (0's and 1's)

Second generation - Assembly Language

Abbreviations are used to write the language, which must then be translated into machine language - the translator is called an "Assembler"

Third Generation

Instructions directed to solve the problem rather than the machine. 1954, a group of IBM scientists led by John Backus began work on a High-level language called FORTRAN ( Formula Translation ).

A compiler is used to translate the code into machine language

By end of 1950's over 200 other high level languages had been developed.

Data

Entered using punched cards and paper tape.

Magnetic tape became main form of secondary storage

People

Computer users were End-users where they developed their own systems. Increasing complexity slowly gave way to the computer scientists in the second generation.

Companies

1952 UNIVAC 1 used to predict Presidential elections by Colombia Broadcasting Corporation (CBS)

1956 AT&T barred by US Department of Justice from competing in the computer industry, since it had a monopoly in the telecommunications field.
