2. What is computer made up of
?
0 A computer is made up of
multiple physical components of
computer hardware, upon which
can be installed an
operating system and a multitude
of software applications to
perform the operator's desired
functions.
3. What is Hardware
0Hardware mean the physical
components of a computer system,
in the form of computer hardware.
5. 0 A motherboard is the central printed circuit board
(PCB) in many modern computers and holds many of
the crucial components of the system, while providing
connectors for other peripherals.
7. 0 Random-access memory (RAM) is a form of
computer data storage. Today, it takes the form
of integrated circuits that allow stored data to be
accessed in any order.
11. First

0 Texas Instruments (TI)
TMS 1000, and
0 Garrett AiResearch's
Central Air Data Computer
(CADC).
A motherboard is the central printed circuit board (PCB) in many modern computers and holds many of the crucial components of the system, while providing connectors for other peripherals. The motherboard is sometimes alternatively known as the main board , system board. The motherboard is the main component inside the case

A hard disk drive is a non-volatile storage device for digital data. It features one or more rotating rigid platters on a motor-driven spindle within a metal case. Data is encoded magnetically by read/write heads that float on a cushion of air above the platters.
An optical disc drive ( ODD ) is a disk drive that uses laser light or electromagnetic waves near the light spectrum as part of the process of reading or writing data to or from optical discs . Some drives can only read from discs, but recent drives are commonly both readers and recorders . Recorders are sometimes called burners or writers . Compact discs , DVDs , HD DVDs and Blu-ray discs are common types of optical media which can be read and recorded by such drives
A microprocessor incorporates most or all of the functions of a computer 's central processing unit (CPU) on a single integrated circuit (IC, or microchip). The first microprocessors emerged in the early 1970s and were used for electronic calculators.
Computer cooling is required to remove the waste heat produced by computer components , to keep components within their safe operating temperature limits. Various cooling methods help to improve processor performance and/or to reduce the noise of cooling fans. Components which produce heat and are susceptible to performance loss and damage include integrated circuits such as CPUs , chipset and graphics cards , along with hard drives (though excessive cooling of hard drives has been found to have negative effects). Overheated parts fail early and may give sporadic problems resulting in system freezes or crashes.
A power supply unit ( PSU ) is the component that supplies power to the other components in a computer. More specifically, a power supply unit is typically designed to convert general-purpose alternating current (AC) electric power from the mains (100-127V in North America, parts of South America, Japan, and Taiwan; 220-240V in most of the rest of the world) to usable low-voltage DC power for the internal components of the computer. Some power supplies have a switch to change between 230 V and 115 V. Other models have automatic sensors that switch input voltage automatically, or are able to accept any voltage between those limits. The most common computer power supplies are built to conform to the ATX form factor. This enables different power supplies to be interchangeable with different components inside the computer. ATX power supplies also are designed to turn on and off using a signal from the motherboard, and provide support for modern functions such as the standby mode available in many computers. The most recent specification of the ATX standard PSU
