Block diagram of a basic computer with uniprocessor CPU. Black lines indicate control flow, whereas red lines indicate data flow. Arrows indicate the direction of flow. In computer science and computer engineering, computer architecture is a description of the structure of a computer system made from component parts. [1]
A block diagram is a diagram of a system in which the principal parts or functions are represented by blocks connected by lines that show the relationships of the blocks. [1] They are heavily used in engineering in hardware design, electronic design, software design, and process flow diagrams. Block diagrams are typically used for higher level ...
The first personal computer to make use of the 80386 was the Deskpro 386, designed and manufactured by Compaq; [11] this marked the first time a fundamental component in the IBM PC compatible de facto standard was updated by a company other than IBM. The first versions of the 386 had 275,000 transistors. [2] The 20 MHz version operates at 4–5 ...
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 ...
x86 (also known as 80x86[ 3 ] or the 8086 family[ 4 ]) is a family of complex instruction set computer (CISC) instruction set architectures [ a ] initially developed by Intel based on the 8086 microprocessor and its 8-bit-external-bus variant, the 8088.
An artist's depiction of a 2000s-era desktop-style personal computer, which includes a metal case with the computing components, a display and a keyboard (mouse not shown) A personal computer, often referred to as a PC, is a computer designed for individual use. [ 1 ] It is typically used for tasks such as word processing, internet browsing ...
A functional flow block diagram (FFBD) is a multi-tier, time-sequenced, step-by-step flow diagram of a system 's functional flow. [ 2 ] The term "functional" in this context is different from its use in functional programming or in mathematics, where pairing "functional" with "flow" would be ambiguous. Here, "functional flow" pertains to the ...
