Motherboard
A motherboard looks like this.The mother board is the centre part of the Computer. It holds the Components and connects them together with a series of circuits and chips . This is also helps power each component

Hard drive(HDD)
• Hard drive is a very important Component.• The hard drive stores most of the computers information including the operating system and all of your programs.• Almost all computers have one or more.

case
• The computer's case hold all the components• It has a USB Port and disk drive• They sometimes have built in fans

Sound card
• The sound card is the main component for sound also know as the audio card
• The input and output of audio signals to and from a computer under control of the computer programs.
• Most sound cards are integrated into the motherboard with the video card

Disk drive
• A disk drive is a optical drive that reads compact disks like DVDs andCD • The drive uses a laser light to read the
information on the disc

CPU (Central processing unit)
• The Central processing unit carries out the instructions of a computer program, it performs the basic input/output operations of the system.
• The power of a CPU is currently measured In gigahertz (GHz) and are 64-bit it ran faster• Newer CPUs use multi cores, this means There is more then one chip inside the processer

Graphics card
• The graphics card gives a video output to the monitor
• They mostly use PCI,PCIe and AGP slots to fit into the motherboard but most modern graphic cards are integrated into the
motherboard • They use HDMI,DVI and VGA ports to connect to
the visual display device

Heat sink
• The heat sink cools the computer down so it does not over heat
• It removes waste heat made by computer components
• It keeps components within their safe operating temperature

Heat extractor
• The heat extractor is for getting rid of waste heat so the CPU will not melt or crash

Power supply
• The power supply in the computer provides all of the different voltages your computer needs to operate properly
• It converts AC voltage from the mains into DC voltage

RAM (random access memory)
• RAM is for running and loading applications• RAM is also used for advance gaming and
graphics software• It also a temporary storage device for
computer data

firewire
• FireWire is a method of transferring information between digital devices, especially audio and video equipment
• Firewire is 400 MB/s or 800 MB/s • Not many peripherals use firewire, it is mainly
used for cameras and camera recorders
