Functions of the main components of a system unit
1.Input/Output port(I/O port):
A port is the point at which a peripheral attaches to a system unit
so that the peripheral can send data to or receive information from
the computer.
2.Power button:
To start on computer

writes to CD-RW media. This drive also allows watching a DVD or burn a CD.
8.Reset button:
Kick of soft boot, instructing the computer to go through the process of
shutting down, which would clear memory and reset devices to their initialized
state. It simply removes power immediately.
9.Zip drive
A high-capacity disk drive that reads from and writes on a Zip disk
10.Floppy drive
A device that reads from and writes on a floppy disk
11.Hard disk drive
Type of storage device that contains one or more inflexible, circular platters
