The ENIAC (Electronic Numerical Integrator And Computer) was the first electronic general-purpose computer, announced to the public in 1946. It was Turing-complete, [45] digital, and capable of being reprogrammed to solve a full range of computing problems. Women implemented the programming for machines like the ENIAC, and men created the hardware.
An ERA drum was the internal memory for the ATLAS-I computer delivered to the U.S. Navy in October 1950 and later sold commercially as the ERA 1101 and UNIVAC 1101. Through mergers , ERA became a division of UNIVAC shipping the Series 1100 drum as a part of the UNIVAC File Computer in 1956; each drum stored 180,000 6-bit characters (135 kilobytes).
The NCR 315-RMC, released in July 1965, was the first commercially available computer to employ thin-film memory.This reduced the clock cycle time to 800 nanoseconds.It also included floating-point logic to allow scientific calculations, while retaining the same instruction set as previous NCR 315 and NCR 315-100.
In operating systems, memory management is the function responsible for managing the computer's primary memory.

The Manchester Baby was designed as a test-bed for the Williams tube, an early form of computer memory, rather than as a practical computer.Work on the machine began in 1947, and on 21 June 1948 the computer successfully ran its first program, consisting of 17 instructions written to find the highest proper factor of 2 18 (262,144) by trying every integer from 2 18 − 1 downwards.
