Power Supply : 

Power Supply 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. The power supply in your PC provides all of the different voltages your computer needs to operate properly. Power supply adaptor. It helps the computer to get as much power as it needs. Why is a power supply useful?

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. Hard drive

Expansion card : 

Expansion card The expansion card in computing is a printed circuit board that can be inserted into an expansion slot of a computer motherboard or backplane to add functionality. One edge of the expansion card holds the contacts that fit exactly into the slot. They establish the electrical contact between the electronics on the card and on the motherboard. Connectors mounted on the bracket allow the connection of external devices to the card. Depending on the form factor of the motherboard and case, around one to seven expansion cards can be added to a computer system. 19 or more expansion cards can be installed in backplane systems. There are also other factors involved in expansion card capacity.

Expansion slot : 

Expansion slot An expansion slot is a expansion port alternatively referred, an expansion slot is a computer which is located on the motherboard or on the riser board that allows additional to be connected to it. Below is a listing of some of the expansion slots commonly found in IBM compatible computers as well as other brands of computers and graphic illustration of a motherboard and its expansion slots.

Motherboard : 

Motherboard In personal computers, a motherboard is the central printed circuit board (PCB) in many modern computers and holds many of the crucial components of the system, providing connectors for other peripherals. The motherboard is sometimes alternatively known as the main board, system board, or, on Apple computers, the logic board. One of the most important components of the PC's base plate. The quality, the better they work other components. On the market there are many manufacturers base.

CD-ROM drive : 

CD-ROM drive CD-ROM drives are necessary today for most programs. A single CD can store up to 650 MB. Of course, it’s nice to have the little bits of extra speed. However, when you consider CD-ROM drives are generally used just to install a program. The extra speed isn't usually very important. The speed can play a big role. A CD-ROM drive, an acronym of "Compact Disc Read-only memory drive") is a pre-pressed compact disc that contains data accessible to, but not writable by, a computer for data storage and music playback. The 1985 “Yellow Book” standard developed by Sony and Philips adapted the format to hold any form of binary data.

Slide 8: 

DVD-ROM drive A DVD is an optical disc storage media format, invented and developed by Philips, Sony, Toshiba, and Panasonic in 1995. DVDs offer higher storage capacity than Compact Discs while having the same dimensions. Pre-recorded DVDs are mass-produced using molding machines that physically stamp data onto the DVD. Such discs are known as DVD-ROM, because data can only be read and not written nor erased. DVDs are used in DVD-Video consumer digital video format and in DVD-Audio consumer digital audio format, as well as for authoring AVCHD discs.

Random Access Memory : 

Random Access Memory RAM ( in English random-access memory , random access memory) is the science type of electronic memory , which allows access to any part in constant time, regardless of its physical location (as opposed to sequential memory, such as magnetic tape , optical disc or hard drive ). Types of RAM DDR2 RAM Windows XP Windows Vista Windows 7 DDR3 DIMM Corsair Intel Socket LGA1366 AMD Phenom II

Central Processing Unit : 

Central Processing Unit Processor ( English Central Processing Unit , an abbreviation of the CPU ) in computer science an essential part of a computer that performs machine code running computer program . It is composed of individual machine instructions that are stored in memory computers. The processor is currently very complex sequential integrated circuit located on the motherboard your computer.

RAM is the science type of electronic memory. A DVD-ROM is an optical disc storage media format, a CD-ROM drives are necessary today for most programs. A hard drive is a hard disk drive  that is a non-volatile, random access digital magnetic data storage device. The expansion card  in computing is a printed circuit board. An expansion slot is a slot located inside a computer on the motherboard or riser board that allows additional boards to be connected to it. In personal computers, a motherboard is the central printed circuit board (PCB) in many modern computers. An expansion slot
