A device used to make hard copies or printouts. A hard copy is a copy of a document on paper. b. allows the computers to play music and make sound. C. This is where a temporary or soft copy of the data is shown to the computer d. user. The user can store this data in the hard disk or floppy disk and make hard copies (on paper) later on. e. This is a device inside the CPU that allows the computer to network (communicate with other computers) or surf the internet (a world wide network of computers). Modems allow e-mails (electronic mail) to be sent from one computer to another using telephone lines. f. This is a storage device for data found inside the CPU. It cannot be seen from the outside. Hard disks now contain enough space or memory to accommodate a very big amount of data. g. This is the brain or intelligence of the computer. It performs h. This stands for Central Processing Unit. The CPU is where the processing and storage happens. It is the part where the processor, hard disk and modem are located. i. (Compact Disk-Read Only Memory) or floppy disk is a device that stores information like a book. Whenever you put one inside a computer, it is like giving a book to a friend to read. J. found in the Central Processing Unit or CPU. These are used to insert a CD ROM or a floppy disk. Computer diskettes or CDs are storage forms of data. You insert a floppy disk into the appropriate drive. Then, the computer reads the data or information on that disk and performs the commands you want for that data. k. This is a tool that we use to click, select and move items on the screen. It command the computer what to do. It lessen the use of a keyboard. I. used to encode (input) information that the computer can "understand". A computer user must know how to type data or information using the keyboard. We use a typewriter to write data or information on paper. In a computer, the data goes inside the computer to be processed instead of paper.
