It is the first test that the computer does when it starts up so that it can make the checks it needs to so it know it has got all the components needed inside. So if theres anything missing it wont function properly and that can result in not working. it looks like a memory card which is on the motherboard and it is a main componet of the computer.
Hard disk
The Harddrive hold all the data which is stored on the computer. It allows the user to save important data. You can get 2 types of Harddrives which allow them to save data onto it. If the Harddrive is not destored it can affect the space on it.
Ports
There are two types of ports in a computer. The first type is parallel and that means that it can transfer data up to 8 bytes at a time. It looks like a printer cable. A series port is when you can only send data at 1 bytes at one time and it is more standard and it is in mouse.
Ram
It is used so that it can open applications on the computer and you can add more RAM if you want to open even more application at a faster speed. It is located on the motherboard of the computer.
Network Card
It is a card which is connected on the computer so that it can get network from the internet either wirelessly or with a wire. And also you can connect Bluetooth devices to it.
Graphics Card
This is what provides the image onto the projector or a monitor and also it send graphical images and data which can then be seen on other devices. It sends out a visually display to devices so that they can have good images.
Internal Memory Rom
It is a small chip that has got data onto it and it is very similar to RAM but there is a different which varys them both a RAM can be changed but a ROM cannot. It can on read files not like a RAM which you can edit files on.
Processor
It is the brain of the computer and according and it controls everything that goes in and out of the computer. The operating system works on depandin on the processor and that can determand the speed that the computer will run. The main function of a processor is
Heat Sink
The heat sink stops and help to keep the processor cool so that they can stop it from heating up. it looks very similar as the fan that cools the whole computer down. it is connected to the motherboard which is the main function of the computer.
Fan
It cools the computer down so that it doesn’t over heat and explodes. it makes sure that the computer cabn stay cool and doesnt overheat which can result in the computer will not function properly.
Power Supply
This is the power which is supplied to the computer through the power pack and without it the computer won’t work.it is connect to the computer through the motherboard.
Start Up Cable
It is a cable it connects the power to the motherboard so that it can allow the hard drive to communicate. It is the first Componet which helps the computer to start up and also function properly.
Motherboard
It is the heart of the computer and it controls and holds together everything so you can attach everything to the CPU. The motherboard helps to connect all the other componets to it.
Internal Memory Catche
It is a piece which holds data so that it can show later on and also be used for that data can be served faster. It is small and also works at very high speeds.
IDE
The IDE is a cable which allows and controls all the data which is being transported around the computer and it is connect to the motherboard so that it can control the storage on a computer. It allows the CPU's data to be transfered through the IDE into the motherboard. It is connected from the harddrive its a cable which transfers data files.
