Over the past couple of lessons in ICT, we learnt about the different parts of the computer and what all of them do. I learnt about the 6 main components that a com
puter needs to work: Motherboard, Hard drive (HDD), Central processing unit (CPU), Power supply, Case and Ram. Each of these components do different things, but all work together to get the computer working.
Motherboard
The motherboard lets all parts of the computer to have power and be able to communicate with each other.
Hard drive
The hard drive keeps all data and applications. It doesn't go that fast, but that's why we have rams.
Ram
A ram has very short term memory, but it is much faster that the hard drive. The hard drive sends information to the ram which sends it to the central processing unit, once all the information is sent to the central processing unit the application starts running.
Central processing unit
The central processing unit processes information. When the power button on a Apple computer is turned on the hard drive automatically sends Mac OS to the ram then eventually sends it to the central processing unit and starts up the whole computer. Nearly everything has to go to the central processing unit to start running.
Case
The case covers everything inside it (motherboard, ram, power supply..etc.). A computer can still work without a case, but probably won't last as long as a computer with a case, and it makes the computer look better and easier to move around.
Power supply
The power supply does what the name says, it supplies power to the motherboard. Without the power supply it will be much harder to turn a computer on.
I think this unit of ICT was fun and informative. We were able to move around and do things then just sit down and write down things.
