called an INput device

Speakers

A temporary memory that stores programs and data that are in process.

Hard-Drive Device

The hard-drive disk is where all the computers information is saved. Therefore is a storage device where info. Is stored.

ROM (Read Only Memory)

The data and instructions in here will be stored in a permanent way.

Keyboard

A keyboard allows you to input characters, letters, and symbols into a computer and they often function as commands.

Printer

A printer is a device that takes text and graphic output from the computer and transforms all the information into paper.

Floppy Disk
