What were the first computers to use a stored program?

Answer 1

EDVAC(1946 - 52) - Electronic Discrete Variable Automatic Computer is the first computer using the stored program concept. Programs were wired on the boards in the earlier models of computers. Dr.John Von Neumann introduced the " stored program " concept . The basic idea behind this concept is that a sequence of instructions and data can be stored in the memory of a computer for automatically directing the flow of operations .

Answer 2

One of the first was the British Collossus vacuum tube computer made in secret during the second world war to decode the Nazi enigma code signals intercepted by radio. Collossus ran a punched paper tape at 30 MPH through an optical reader. The stored program was written by Alan Turing amongst others at the Bletchley park Mansion in the Midlands.

Answer 3

The Manchester Small-Scale Experimental Machine (SSEM), nicknamed Baby, was the first stored program computer which implemented stored program concept (also known as Von Neumann Concept).

It ran its first program on 21 June 1948.It was build as a test bed for the Williams tube(an early form of computer memory)and not as a machine for practical use.

Answer 4

The Manchester Small-Scale Experimental Machine (SSEM), nicknamed Baby, was the world's first stored-program computer. It was was a very limited prototype computer built at the Victoria University of Manchester, England, by Frederic C. Williams, Tom Kilburn and Geoff Tootill, and ran its first program on 21 June 1948. The SSEM had a 32 bit word length and a memory of only 32 words using CRT based DRAM, the only arithmetic operations implemented in it's ALU were subtraction and negation. It operating speed was roughly 1.1kIPS.

The circuits designed and verified on the SSEM were then improved and used to build the Manchester Mark 1. The Manchester Mark 1 in turn quickly became the prototype for the Ferranti Mark 1, the world's first commercially available general purpose computer.

Answer 5

The Z3 is the first freely programable computer made by Konrad Zuse Made by Konrad Zuse , the Z3 is th first freely programable computer.

Answer 6

The Manchester Baby was the first running stored program computer, with a grand total of 32 words of memory, each word was 32 bits wide.
