CPU

What a cpu does is that it process instructions that gathers from decoding the code in the programs they are in and other things like files. It has four primary functions:Fetch,decode,execute,and writeback.

Hard drive

The hard drive is referred to hard drive disk and its also abbreviated as HD or HDD. The hard drive is the computers main storage media drive that permanetly stores all data on the computer.

Power Supply

a power supply's job is to convert an alternating current know as the AC any ways it's signal is coming from your wall outlet into a direct current which is known as the DC signal. The process is done by stepping down the input voltage level with a transformer and then rectifying (determine) it to convert to Dc.

RAM

A Ram could be consider as a main memory but either way its where the computer stores programs, applications or data that is being used. The computer can't really work without the Ram.

Mother Board

A motherboard is a printed circuit board containing the principal components of a computer or other device, with connectors into which other circuit boards can be slotted.

Clock Battery

It's a direct current battery, to provide power in the absence of the main power supply.

Troubleshooting

Troubleshooting is a process of solving a problem to an issue.Often it involves the process elimination, where the technician will follow a set of steps in order to figure out the problem or to fix the problem. The first thing you do is to make sure everything is plugged and put in,in the right space. Second is to turn on the computer and see if it shows you some kind of error message or see if it doesn't even turn on. If it does happen it means something is seriously wrong and needs to be fix as soon as possible! Then what could be wrong is the wires is put on the wrong place or wires aren't connected or sometimes it just doesn't work any more.
