Computer Flashcards
Central Processing Unit
the part of a computer in which operations are controlled and executed.
Microprocessor
A microprocessor is an electronic component that is used by a computer to do its work. It is a central processing unit on a single integrated circuit chip containing millions of very small components including transistors, resistors, and diodes that work together.
Control Unit
Control unit. … The control unit (CU) is a component of a computer’s central processing unit (CPU) that directs the operation of the processor.
arithmetic logic unit
An arithmetic logic unit (ALU) is a combinational digital electronic circuit that performs arithmetic and bitwise operations on integer binary numbers.
Motherboard
A motherboard is the main printed circuit board found in general purpose computers and other expandable systems. It holds, and allows, communication between many of the crucial electronic components of a system, such as the central processing unit and memory, and provides connectors for other peripherals.
Binary Code
DescriptionA binary code represents text, computer processor instructions, or any other data using a two-symbol system. The two-symbol system used is often “0” and “1” from the binary number system.
Bit
A bit has a single binary value, either 0 or 1.
Byte
a group of binary digits or bits (usually eight) operated on as a unit.
Base 2
In mathematics and digital electronics, a binary number is a number expressed in the base-2 numeral system or binary numeral system, which uses only two symbols: typically “0” and “1”. The base-2 numeral system is a positional notation with a radix of 2. Each digit is referred to as a bit.
ASCII
DescriptionASCII, abbreviated from American Standard Code for Information Interchange, is a character encoding standard for electronic communication. ASCII codes represent text in computers, telecommunications equipment, and other devices.
