What is a power supply? A power supply is a device that supplies electrical energy to one or more electric loads. Every power supply must obtain the energy it supplies to its load, as well as any energy it consumes while performing that task, from an energy source. Why is a power supply useful?The power supply in your PC provides all of the different voltagesyour computer needs to operate properly. Power supply adaptor.It helps the computer to get as much power as it needs.
Hard drive A hard drive is a hard disk drive that is a non-volatile, random access digital magnetic data storage device. It features rotating rigid platters on a motor-driven spindle with in a protective enclosure. Introduced by IBM in 1956, hard disk drives have decreased in cost and physical size over the years while dramatically increasing in capacity.

The expansion card in computing is a printed circuit board that canbe inserted into an expansion slot of a computer motherboard orbackplane to add functionality. One edge of the expansion cardholds the contacts that fit exactly into the slot. They establish theelectrical contact between the electronics on the card and on themotherboard.Connectors mounted onthe bracket allow theconnection of externaldevices to the card.Depending on the formfactor of the motherboardand case, around one toseven expansion cards canbe added to a computersystem. 19 or moreexpansion cards can beinstalled in backplanesystems. There are alsoother factors involved inexpansion card capacity.
An expansion slot is a expansion port alternatively referred, anexpansion slot is a computer which is located on themotherboard or on the riser board that allows additional to beconnected to it. Below is a listing of some of the expansion slotscommonly found in IBM compatible computers as well as otherbrands of computers and graphic illustration of a motherboardand its expansion slots.
In personalcomputers, a motherboard isthe central printed circuitboard (PCB) in manymodern computers and holdsmany of the crucialcomponents of thesystem, providing connectorsfor other peripherals. Themotherboard is sometimesalternatively known as the mainboard, systemboard, or, on Apple computers, the logic board. One of themost important components ofthe PCs base plate. Thequality, the better they workother components. On themarket there are manymanufacturers base.
CD-ROM drives are necessary today formost programs. A single CD can store upto 650 MB. Of course, it’s nice to have thelittle bits of extra speed. However, whenyou consider CD-ROM drives aregenerally used just to install a program.The extra speed isnt usually very important.The speed can play a big role.A CD-ROM drive, an acronym of "CompactDisc Read-only memory drive") is a pre-pressed compact disc thatcontains data accessible to, but not writableby, a computer for data storage and musicplayback. The 1985 “Yellow Book” standarddeveloped by Sony and Philips adapted theformat to hold any form of binary data.
A DVD is an optical disc storage mediaformat, invented and developedby Philips, Sony, Toshiba, and Panasonic in1995. DVDs offer higher storage capacitythan Compact Discs while having the samedimensions.Pre-recorded DVDs are mass-producedusing molding machines that physicallystamp data onto the DVD. Such discs areknown as DVD-ROM, because data can onlybe read and not written nor erased.DVDs are used in DVD-Video consumer digitalvideo format andin DVD-Audio consumer digitalaudio format, as well asfor authoring AVCHDdiscs.
RAM ( in English random-accessmemory , random access memory) isthe science type of electronic memory ,which allows access to any part inconstant time, regardless of itsphysical location (as opposed tosequential memory, such as magnetictape , optical disc or hard drive ). Types of RAM DDR2 RAM Windows XP Windows Vista Windows 7 Corsair DDR3 Intel Socket LGA1366 DIMM AMD Phenom II
Processor ( English Central Processing Unit , anabbreviation of the CPU ) in computer science an essentialpart of a computer that performs machinecode running computer program . It is composed ofindividual machine instructions that are storedin memory computers. The processor is currently verycomplex sequential integrated circuit located on themotherboard your computer.
