5. A special diagnostic mode designed for troubleshooting errors that occur during the boot process.






6. A printer that has tiny hammer-like keys that strike the paper through an inked ribbon - thus making a mark on the paper. The most common impact printer is the dot-matrix printer.






7. When data merely travels the entire length of the communications medium and is received by all network devices.






8. 'A physical address - similar to a serial number on an appliance - that is assigned to each network adapter; it is made up of six 2-digit characters such as 01:40:87:44:79:A5.'






9. Any part of the computer you can physically touch.






10. A computer that is intended for use at a single location. A desktop computer consists of a case that houses the main components of the computer - plus peripheral devices.
