8. Aka interrupt request line.






9. Memory chips that provide much slower access than SRAM chips but that can store several megabytes of data on a single chip (or hundreds of megabytes - or even gigabytes - when they are packaged together on a "stick").






10. A power supply standard that has both the 20-pin connector for the motherboard and a 4-pin 12 V connector.






11. A group of tests - stored in the BIOS and performed as a PC boots up - to check for the presence and function of system components.

13. Aka random access memory.






14. Aka musical instrument digital interface.






15. A key on a laptop that is combined with the FN key to bring up a small volume control panel on the display. Using the up (?) or right (?) arrow key - the volume will increase. To decrease the volume - press the FN key and the SPEAKER VOLUME key along






16. The difference in value between a display's brightest white and darkest black. Modern LCD displays have a contrast ratio of 500:1 or greater.






17. The BIOS configuration settings - also called system settings - accessed via a special BIOS-based menu during system startup.

22. A service of the operating system on a laptop that detects when a card has been inserted.






23. In the laser printing process - the stage in which the printer's high-voltage power supply (HVPS) conducts electricity to the primary corona wire so it can pass the voltage on to the printer's electro-photosensitive drum.






24. Aka thumb drive.






25. An LCD display characteristic that indicates the amount of time in milliseconds (ms) it takes for a single pixel to go from the active to the inactive state and back again.






26. A drive that can be safely installed and removed while a computer is up and running without damaging the data stored on the drive.






27. In Windows - a security account that contains one or more local user accounts - and when a computer is a member of a Windows domain - may also contain domain user or group accounts.






28. A key on a laptop that is combined with the FN key to toggle the laptop's speaker on and off. The SPEAKER ON/OFF key is usually one of the standard function keys - such as F3 - that displays a speaker symbol.






29. In the laser printing process - the step in which the laser beam creates a negative of the image that will eventually appear on the printout. Each place that the laser beam touches loses most of its charge - creating an image - whereas the rest of th






30. A sleep mode that is available on any computer that supports ACPI power management. It conserves power while saving the desktop in RAM memory in a work state. To resume - you simply press the power button - and the desktop is quickly displayed.






31. The original version of the IEEE 1394 standard that supports speeds up to 400 Mbps.






32. The use of a biometric for authentication.






33. Aka complementary metal-oxide semiconductor.






34. Aka thermal compound.






35. Aka nickel-cadmium.






36. A laptop is a small - easily transported computer - generally weighing less than 7 pounds and with roughly the same dimensions as a 1- to 2-inch-thick stack of magazines. Laptops computers have an all-in-one layout in which the keyboard - and often t






37. A firewall service that inspects (or filters) each packet that enters or leaves the network - applying a set of security rules defined by a network administrator - and not allowing packets that fail inspection to pass between networks.






38. A measurement of the volume of electrons - also called current. It is calculated with the formula amps = watts / volts.

40. A type of DIMM memory module used in laptops.






41. In reference to IDE PATA drives - the master drive on the first channel.






42. Any type of computer that you can easily transport and that contains an all-in-one component layout.






43. A plug designed for testing a specific port type (e.g. - serial - parallel - or USB). The plug does not connect to a cable but reroutes the sending pins to the receiving pins. Using special software on the computer - a loopback test is performed in w






44. In reference to a memory module - the number of memory modules required to match the data bus width of the processor.






45. A type of RIMM memory module used in laptops.






46. The role of the first EIDE drive on a PATA channel.
