computer components
hardware
1) c p u
which acts as brain of the computer. It does the computing and processing works of the computer; such as calculating your data with formulas in Microsoft Excel worksheet, processing the raw data into a usable one, etc.
2) r a m
works as volatile data memory for programs to work. Imagine this: program works in a office workspace and RAM is size of the cubicle. Larger cubicle means program have bigger working space and thus could work faster if it needs to. Who determines which program need larger or smaller cubicle? Kernel does (which is a part of OS). Data stored in RAM won’t survive a power-off.
3) storage drive
Well… it acts as data storage where your data and program innards reside. If RAM is the office cubicle, then storage unit is the office storage room. Obviously, the larger it is then the more you could store your data. Storage drive usually comes in HDD (Hard Disk Drive) which is a quite dated but still largely used; the other one is SSD (Solid-state Disk) which is newer and sports faster read and write operation. Data stored in storage drive last longer than RAM (if the drive is not faulty, but it will deteriorates as aging kicks in).
4) optical drive
reads (or write) your optical media such as CD, DVD, or BD. Usage trend for this media is declining, so is for the usage of optical drive.

8) Motherboard
is the central of those component above where circuity wonder flows process and data to appropriate component. If it unable to works properly, it could stop whole system to a grinding halt.
9)Input device,
such as: mouse, keyboard, touch-pad, scanner, optical drive, microphone, etc. Anything that gives input to the system, usually by user.
10)Output device
such as: monitor, printer, and speaker. Self-explanatory, it outputs whatever data that has processed by the system.
11)Cooling system
works as heat ventilation that is generated by system. Common setup is using fans and heat-sink pipes which vents the heat from CPU to fan. Additional cooling, if required, people use hydro-cooling system which use liquid to transfer heat.

software
1) BIOS
is the most inner OS that embedded with motherboard. BIOS sets up the starting sequence and basic working of a system. Crippled BIOS means you will find you can’t start the system before repairing the BIOS or changing the motherboard if it unrepairable.
