The IAS machine was a binary computer with a 40-bit word, storing two 20-bit instructions in each word. The memory was 1,024 words (5 kilobytes in modern terminology). Negative numbers were represented in two's complement format. It had two general-purpose registers available: the Accumulator (AC) and Multiplier/Quotient (MQ).
The MANIAC I (Mathematical Analyzer Numerical Integrator and Automatic Computer Model I) [1][2] was an early computer built under the direction of Nicholas Metropolis at the Los Alamos Scientific Laboratory. It was based on the von Neumann architecture of the IAS, developed by John von Neumann. As with almost all computers of its era, it was a ...
von Neumann architecture. The von Neumann architecture —also known as the von Neumann model or Princeton architecture —is a computer architecture based on a 1945 description by John von Neumann, and by others, in the First Draft of a Report on the EDVAC. [ 1 ] The document describes a design architecture for an electronic digital computer ...
Retrieved 2010-10-04. "Reduced instruction set computer architectures have attracted considerable interest since 1980. The ultimate RISC architecture presented here is an extreme yet simple illustration of such an architecture. It has only one instruction, move memory to memory, yet it is useful."
A CPU cache [ 71 ] is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from the main memory. A cache is a smaller, faster memory, closer to a processor core, which stores copies of the data from frequently used main memory locations.
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 ]

700 pounds (320 kg) The Atanasoff–Berry computer (ABC) was the first automatic electronic digital computer. [1] Limited by the technology of the day, and execution, the device has remained somewhat obscure. The ABC's priority is debated among historians of computer technology, because it was neither programmable, nor Turing-complete. [2]
