anti static wrist band

Firstly i need to wear the anti static wrist band.This can be seen in my other photos with me wearing it.It is done so that you do not have any electricity or static on you causing you to break a component on the computer

Installing a dvd drive

Firstly i needed to put the disk drive in through the front of the computer and then connect it.





Installing to the motherboard and power supply

I then connect the disk drive at the back to the motherboard so the computer recognises it and so it can work. Secondly i connect it to the power supply so when the disk drive is turned on it will work.

When the computer is then turned on it will load up and give you instructions to install it through the operating system.

Graphics Card

A Graphics Card also known as a Video Card is an internal device which controls and produces the display on your screen. Graphic cards come with various specifications, and unless they are built-in to the motherboard (mainboard) they have their own RAM onboard.The term is usually used to refer to a separate, dedicated expansion card that is plugged into a slot on the computer's motherboard, as opposed to a graphics controller integrated into the motherboard chipset. An integrated graphics controller may be referred to as an "integrated graphics processor" (IGP).

Internal memory

Internal memory is used for two main purposes:
· To store programmes that are being run
· To store data that the program works on.
Although programs (ie software) may seem different from data, they are treated in exactly the same way- the computer excutes a program, instruction by instruction.
Within the computer there are two types of memory:
Internal cache- this is located inside the CPU chip also called a primary cache or on- die cache.
External cache- is also on the motherboard but not within the CPU chip- also called secondary cache.

Peripherals

A peripheral is a piece of computer hardware that is added to a host computer ,i.e. any hardware except the computer, in order to expand its abilities. More specifically, the term is used to describe those devices that are optional in nature, as opposed to hardware that is either demanded or always required in principle. Printers, scanners, USB keys, and DVD players are the essential extensions to the basic PC.

Ports

Ports are names or "handles" given to various network connections your computer uses to communicate with other computers. For example, your connection to the Internet is through a port protocol called TCP/IP (Transmission Control Protocol/Internet Protocol) using well-known ports such as HTTP or "port 80."

HARD DRIVE CONFIGURATION AND CONTROLLERS

In computer hardware, a 'port' serves as an interface between the computer and other computers or peripheral devices. Physically, a port is a specialized outlet on a piece of equipment to which a plug or cable connects. Electronically, the several conductors making up the outlet provide a signal transfer between devices. Hardware ports may be physically male (unusual, since protruding pins easily break, a fate best left to inexpensive matching cable ends) or female (usual on equipment).
