What are the Parts of computers and its function?
The CD rom, the floppy, mouse, printer, keyboard, monitor, and system unit.CD-ROM
These are the silvery plastic disks that look just like music CD's. Application software (programs) usually come written on these, and special kinds of CD-ROM's can be used to store large amounts of data.Floppy Disk
This is a somewhat floppy coated disk housed inside a not-floppy plastic case about the size of a square beverage coaster. The floppy, once inserted into the appropriate slot in the system unit, is used to store files. Once the files have been written, the floppy can be removed for use on another computer or for safe keeping as a backup or data archive.Keyboard
This is organized like a regular typewriter keyboard and has some extra keys for special functions. Attaches to the system unit with a cord.Monitor (or display)
The part of the computer that looks like a small TV and shows you what is going on. Usually has 2 cords: one for power and the other for connecting to the system unit.Mouse
This device is about the size of a pack of cigarettes and allows the computer user to select from options displayed on the screen. By sliding the mouse around on a flat surface (usually a thin foam pad) the user moves a pointer on the screen. When the tip of the pointer is positioned over the desired item, the user clicks the mouse (a single or double click) to select the item. A single cord connects the mouse to the system unit.System Unit (sometimes referred to as CPU)
The part of the computer that is box-like, usually the size of a medium to large briefcase with slots for disks and connectors on the back. Inside this box are the microprocessor, disk drives and other elements that work together to do the actual computing.Printer a peripheral which produces a hard copy of documents stored in electronic form, usually on physical print media such as paper or transparencies.
