1. Components of a computerAdam Greenhalgh

2. CPU

The Central processing unit (CPU) is the brain of the computer. It controls everything that goes on inside the computer.

3. CPU Advanced

The CPU is connected to the motherboard by a ZIF socket and then connected to the heat sink using thermal compound. You Can get a duel core processor or an Intel core processor these are your makes off CPU

4. Hardrive

The Hardrive is used to save you work to so all the work you save you will find on the Hardrive.

5. Hardrive Advanced

You can also create a Slave drive to the Hardrive this will help increase your memory so you have more space to save your work. You can also make up to 4 partitions on your Hardrive. Hardrives come in all different sizes from 1GB to 1 terabyte.

6. Graphics card

A graphics card is found on the motherboard and this is something that provides the computer with graphics.

7. Graphics card Advanced

If you have a good graphics card it will have more pixels than one that is not as good so this means you will have better graphics.

8. Motherboard

The motherboard is found inside the base unit you will find things such as Ram, Rom , Graphics card, video card etc on this.

9. Motherboard Advanced

Motherboards can have different form factors they can come in all different shapes and sizes and they will also change depending on whether you have a laptop or a computer.

10. USB Connector

A USB connector is a slot on your computer where you can place an USB device e.g. memory stick to load data on to your computer.

11. USB Connector Advanced

USB stands for Universal serial bus. You can get different types of USB you can get USB 1.0, USB 1.1 and USB 2.0. USB 2.0 is the fastest out of all off them while USB 1.0 is the slowest. USB is also hot swappable.

12. Heat sink The heat sink sits on top off the CPU and transfers heat away from the CPU which then prevents the computer from over-heating . These all also generallymade from aluminium. 13. Heat Sink Advanced The heat sink sits on top of the CPU but you can get different types off ways off cooling the CPU down. You can get a fan that sits on top off then heat sink or you can get a water cooling system that will also transfer the heat away from the CPU. 14. Ram Ram stands for random access memory this is a form off computer data storage. This allows you to edit your work once it has been saved. 15. Rom

Rom stands for read only memory, this is also a data storage device but if you store work in rom this means your work is then not able to be modified.

16. Eprom

Eprom stands for erasable program read only memory and this is a memory chip that retains data once the power supply for the computer is switched off.

17. Adapter cards

PCI is used for attaching hardware devices in a computer, these can be fitted onto the motherboard itself or of an integrated circuit.

PCIe ( peripheral component interconnect express) is a computer expansion card that has a few improvements over other bus standards such as lower I/O pin count.

18. SATA

SATA ( serial advanced technology attachment is a computer bus and is used to connect host bus adapters and mass storage devices.

19. PATA

PATA is an interface standard for the connection of storage devices such as solid-state drives, hard disks and floppy drives.

20. SCSI

SCSI ( small computer system interface) is used for physically connecting or transferring data between peripheral devices or computer

21. Input devices

Keyboard

Games controller

Mouse

Microphone

Touch screen
