Generation 1 (1944-1953)

Generation 1 (1944 – 1953)


This generation was brought on by the invention and use of vacuum tubes.

These tubes allowed for thousands of calculations per second.

Hz (Hertz) = 1/instruction cycle time

6 seconds per instruction = 1/6 = 0.17 Hz

These days, we easily achieve 1 GHz, meaning an instruction takes a nanosecond

At this time, magnetic drums were also used. These spun under the read/write head as a form of memory.

This is also when machine language was created, written completely in binary.

Programs were written in an artificial language (called assembler), which was then translated to machine language.
