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).
Business Process Model and Notation (BPMN) is a standard for business process modeling that provides a graphical notation for specifying business processes in a Business Process Diagram (BPD), [3] based on a flowcharting technique very similar to activity diagrams from Unified Modeling Language (UML). [4] The objective of BPMN is to support ...
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 with these components:
MANIAC I. The MANIAC's arithmetic unit nearing completion in 1952. 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 ...
An open PDP-8/E with its logic modules behind the front panel and one dual TU56 DECtape drive at the top A "Straight-8" running at the Stuttgart Computer Museum. The earliest PDP-8 model, informally known as a "Straight-8", was introduced on 22 March 1965 priced at $18,500 [3] (equivalent to about $178,900 in 2023 [4]).
A functional organizational structure is a structure that consists of activities such as coordination, supervision and task allocation. The organizational structure determines how the organization performs or operates. The term "organizational structure" refers to how the people in an organization are grouped and to whom they report.
The analytical engine was a proposed digital mechanical general-purpose computer designed by English mathematician and computer pioneer Charles Babbage. [ 2 ][ 3 ] It was first described in 1837 as the successor to Babbage's difference engine, which was a design for a simpler mechanical calculator. [ 4 ]
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."
