| Chip | An integrated circuit. A thin piece of silicon that contains all the components of an electronic circuit |
| Disk Drive | A mechanism that holds, spins, reads, and writes either magnetic or optical disks |
| Embedded processor | A chip designed with a specific set of usable instructions. |
| Expansion Slot | A connector designed to allow the addition of printed circuit boards-daughter boards-motherboards |
| Hardware | The physical parts of the computer system-keyboard,monitor,and computer case |
| Information Processing | Capturing, storing, updating, and retrieving data and information |
| Input | The data that is entered into a computer |
| Integrated circuit | A complete circuit on a chip, built by a chip fabrication process |
| Keyboard | A computer input device that uses a set of keys to put data into the computer |
| Memory | A place to store information-RAM, ROM |
| Microprocessor | Co-ordinates all of the actions of the computer carrying out instructions, performing calculations, and interacting with all the components |
