Components Cole

Motherboard • The motherboard is the main part of the computer to make all of the

other components work.• The motherboard holds all the components such as: RAM slots, CPU,

graphics card, heat sink/fan. Sockets, internal and external connectors, and various ports are also placed on the motherboard.

• You will need a motherboard to makeYour computer work.Some different form factors of the motherboard are: ATX,LPX,NLX and BTX.ATX=Advanced Technology extended.LPX= This is an old version of NLX.NLX=New Low Profile Extended.BTX=Balanced Technology extended.

Hard Drive (HDD)

• The hard drive is where you save all of your work or anything else.

• IDE=Integrated Drive Electronics.• EIDE=Enhanced Integrated Drive Electronics.• PATA=Parallel Advanced Technology

Attachment• SATA=Serial Advanced Technology Attachment• SCSI=Small Computer System Interface

Computer case

• The computer case holds all of the computer components also it has 2 USB ports and 2 USB ports at the back.

• You need one of these to plug in a mouse and a keyboard

Sound card

• The sound card is the main component for sound also know as the audio card.

• You can also plug in a speaker and microphone and you can put in a gaming controller.

Disk drive

• The disk drive is where you can put your DVD CD and games and it will run it

Graphics card

• The graphics card it what you need to play games and watch films and do anything else that you want to do.

• This also controls what you see on your computer screen

CPU (Central Processing Unit)

• The CPU processes instructions that it gathers from decoding the code in programs and other files. There are many different types of CPU’s such as: i3, i5, i7. There is 2 main types of CPU’s: such as AMD, and Intel. (The I stands for Intel.)

• There are 3 types of Cores to the CPU, these are Dual, Quad and Single Core. The quad core is faster because there is 4 processers sharing the same job, Furthermore the quad core will also be hotter because there is 4 of them. For instance if I have got an i7 quad core 2.2Ghz it will be 8.8Ghz.

• The CPU has four primary functions: Fetch, decode, execute and write back.

Heat Extractor

• It is used for getting rid of heat in the computer so it wont blow up or melt.

•

Heat Sink/Fan

• The heat sink/fan is used so that your computer doesn’t overheat

Ram(Random Access Memory)

• You need ram to run and load any applications • Advanced gaming or graphics software require

large amounts of RAM. • Most computers have 3 or 2 gigabits of RAMYou can also buy RAM andUpgrade your computersSpeed/Memory.

Power Supply

• A power supply is what you need for your computer to work. • You will need one of these for your computer to operate

properly.• DC Voltage• Power=Watts• Voltage=Volts• Amps=Ohms• The power supply converts AC into DC.• DC= Direct Current.• AC= Alternating Current.

Firewire

• It is where you can transfer data From the device to the computer e.g. if you have pictures on a camera You can put them on your computer using one of these cablesIts similar to a USB

ROM

• ROM is ‘Read Only Memory’.• Data stored in ROM cannot be modified or can be modified

but very slowly, with some difficulty, so its mainly used to distribute firmware.

• Some different types of ROM are:ROM, PROM, EPROM, EEPROMROM= Read Only Memory.PROM= Programmable Read-Only Memory.EPROM= Erasable Programmable Read-Only Memory.EEPROM= Electorally Erasable Programmable Read-Only Memory.

BIOS AND CMOS

• The definition of BIOS is; A set of computer instructions in firmware that control input and output operations.

• The bios checks to see if any input/output devices are connected properly.
