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 ...
IAS machine: 1951 1 Built at the Institute for Advanced Study (IAS), sometimes called the von Neumann machine, since design was described by John von Neumann (the Von Neumann architecture). 1,500 tubes. It was the basis of about 15 other computers. MESM: 1951 1 First universally programmable computer in USSR, built near Kiev, used 6,000 vacuum ...
Green computing, green IT (Information Technology), or ICT sustainability, is the study and practice of environmentally sustainable computing or IT.. The goals of green computing include optimising energy efficiency during the product's lifecycle; leveraging greener energy sources to power the product and its network; improving the reusability, maintainability, and repairability of the product ...
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.
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 ...
A computer is a machine that can be programmed to automatically carry out sequences of arithmetic or logical operations (computation). Modern digital electronic computers can perform generic sets of operations known as programs. These programs enable computers to perform a wide range of tasks. The term computer system may refer to a nominally ...
DEC 16-bit. Successor. VAX-11. The PDP–11 is a series of 16-bit minicomputers sold by Digital Equipment Corporation (DEC) from 1970 into the late 1990s, one of a set of products in the Programmed Data Processor (PDP) series. In total, around 600,000 PDP-11s of all models were sold, making it one of DEC's most successful product lines.
