How computers work?
14
Integrated circuit: Sometimes called a chip or microchip is a semiconductor on which thousands or millions of tiny resistors, capacitors, and transistors are fabricated. It can function as an amplifier, oscillator, timer, counter, computer memory.
Central processing unit: is the brain of the computer, where most calculations take place.
Arithmetic and logic unit: is the part of the computer that carries out arithmetic and logic operations.
Control unit: is a circuitry that directs operations within computer’s operations.
Clock speed: refers to the number of pulses per second generated by an oscillator.
Hertz: Is the frequency unit of one cycle per second. It is especially used for the sound.
MHz: Is the frequency unit of one cycle per second. It is especially used for measuring the speed of digital data
GHz: Is the frequency unit of one cycle per second. It is especially used for measuring microwave unit of frequency.
Cache memory: it’s purpose is to store program instructions that are frequently referenced by software during operation.
RAM memory: also referred as main memory, is a hardware device that allows information to be stored and retrieved.
ROM memory: is “built in” computer memory containing data that can only be read and not written.
CMOS memory: a small battery powered memory
Analog Signal: these signals must be limited to a range of maximum and minimum values.
Digital Signal: they must have a fine set of possible values.
Binary system: a system in which information can be expressed by numbers 0 and 1.
