The Z3 was a German electromechanical computer designed by Konrad Zuse in 1938, and completed in 1941. It was the world's first working programmable , fully automatic digital computer . [ 3 ] The Z3 was built with 2,600 relays , implementing a 22- bit word length that operated at a clock frequency of about 5–10 Hz . [ 1 ]
The Z1 was a motor-driven mechanical computer designed by German inventor Konrad Zuse from 1936 to 1937, which he built in his parents' home from 1936 to 1938. [1] [2] It was a binary, electrically driven, mechanical calculator, with limited programmability, reading instructions from punched celluloid film.

The Datamatic Division of Honeywell announced the H-800 electronic computer in 1958. The first installation occurred in 1960. A total of 89 units were delivered. The H-800 design was part of a family of 48-bit word, three-address instruction format computers that descended from the Datamatic 1000, which was a joint Honeywell and Raytheon project started in 1955.
A program is a set of instructions used to control the behavior of a machine.Examples of such programs include: The sequence of cards used by a Jacquard loom to produce a given pattern within weaved cloth.
Installing the magnetic drum in 1954 opened the way to develop a control program for running programs dealing with matrices. Following urging by J. M. Hahn [13] [14] of the British Aircraft Corporation, [15] Brian W. Munday developed General Interpretive Programme (GIP), which required only simple codewords to run a collection of programs called "bricks".
