1. The metal or plastic case that holds all the physical parts of the computer together - including the computer's processor (its brains) - its memory - and the many circuit boards that help the computer function.






2. 'A special signal sent to all network nodes - alerting them that a data collision has occurred.'






3. 'A device that reads information from a magnetic strip on the back of a credit card-like access card (such as a student ID card); card readers are easily programmed by adding authorized ID card numbers - Social Security numbers - and so on.'






4. A network made up of local area networks (LANs) connected over long distances.






5. A power-management mode that saves the current state of the current system to the computer's hard drive.






6. The access method that ring networks use to avoid data collisions.






7. 'A device designed to store media - share media across the network - and back up files on computers connected to a home network.'






8. 'A device that enables the computer (or peripheral) to communicate with the network using a common data communication language - or protocol.'






9. A small segment of data that is bundled for sending over transmission media. Each packet contains the address of the computer or peripheral device to which it is being sent.






10. A device that allows you to capture sound waves - such as those created by your voice - and transfer them to digital format on your computer.






11. The process of connecting to a wireless network without the permission of the owner of the network.






12. 'The set of programs on a computer that helps a user carry out tasks such as word processing - sending e-mail - balancing a budget - creating presentations - editing photos - taking an online course - and playing games.'






13. The set of programs that enables a computer's hardware devices and application software to work together; it includes the operating system and utility programs.






14. A heavily secured server located on a special perimeter network between a company's secure internal network and its firewall.

18. A nonimpact printer that sprays tiny drops of ink onto a paper.






19. A server used to fulfill one specific function (such as handling e-mail).






20. 'A prediction - named after Gordon Moore - the cofounder of Intel; states that the number of transistors on a CPU chip will double every two years.'
