2. A printer that uses a light beam (laser) in the printing process.






3. Aka time to live.






4. A portion of system memory used by a video adapter built into a motherboard.






5. A KVM switch that uses software and special keyboard commands to switch among controlled computers. Also called anactive KVM switch.






6. A Windows Advanced Options menu choice used to send debugging information about the Windows startup over a serial cable to another computer running a special program called a debugger.






7. A method used by several software manufacturers to combat software piracy. The formal name for Microsoft's activation is Microsoft Product Activation (MPA).






8. The utility to use when doing a single data and settings transfer to a new Windows Vista computer from one running Windows XP or Windows Vista.






9. A solid-state storage standard for high-capacity (2 - 4 - and 8 GB) memory cards that are tiny






10. Aka Simple Mail Transfer Protocol.






11. A component that you can install into a system onsite - such as memory modules - heat sinks - and CMOS batteries.






12. A depressed area on an optical disc that is alternated with raised areas to be interpreted as data.






13. Aka thumb drive.






14. The practice - mostly among gamers - of modifying a computer case.






15. Aka systray.






16. A DVI mode that supports downward compatibility with analog displays.






17. A wide area network (WAN) connection that allows a large amount of data to be transmitted. Broadband WANs includes cellular - ISDN - DSL - cable - T-carrier - satellite - and fiber.






18. A device - usually resembling a power strip - that protects equipment from power surges.






19. A device that converts digital signals from the broadband connection to voice for the analog phone and the analog voice signals to digital signals for the digital network.






20. A CRT video setting - also known at horizontal hold - that holds the image horizontally on the screen.






21. Two or more disks working together in one of the several RAID schemes.






22. A device that converts DC current to AC. An inverter is required in a laptop to provide the AC current required by the display.






23. A pen-sized tool that has a plunger at one end. When pressed - the plunger causes small - hooked prongs to extend from the other end of the tool for retrieving dropped objects from inside a computer.






24. A shared folder on a distribution server containing the source files for a remote installation.






25. A measurement of a body part - such as a fingerprint or retina scan.






26. The format in which IP addresses are usually shown - with decimal numbers separated by "dots" as in 192.168.100.2.






27. The delivery of electricity (as from a wall outlet) in which the flow of electrons reverses periodically and has alternating positive and negative values.






28. A WAN connection that uses existing copper telephone wire for the communication circuit. To accomplish this - a DSL modem splits the existing phone line into two bands; voice transmission uses the frequencies below 4000 Hz - whereas data transmission






29. A RAID array in which every time data is written to disk - a portion (block) is written to each disk in turn - creating a "stripe" of data across the member disks. RAID 0 uses the total disk space in the array for storage - without protecting the dat






30. Aka display power-management signaling.






31. Aka expansion bus.






32. An external bus that connects into the PC's PCI bus. With USB - you can theoretically connect up to 127 devices to your computer.






33. A method for allocating disk space on hard disks in which configuration information for each dynamic disk is located on the disk space beyond the first physical sector. This configuration information is stored outside of any volume on the hard disk.






34. The default Windows file system that includes many important features - including encryption and permissions.






35. The second version of the IEEE 1394 standard; it supports speeds up to 3.2 Gbps and distances of up to 100 meters.






36. Aka Domain Name Service.






37. A protocol used by e-mail clients for communicating with e-mail servers. This protocol is replacing the POP protocol. IMAP allows users to connect to e-mail servers and not only retrieve e-mail - which removes the messages from the server - as they c






38. 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






39. Aka Dynamic Host Configuration Protocol.






40. Aka wireless access point.






41. Program code that provides a way for someone to gain access to a computer while bypassing security. Only a person who knows how the back door works can use it - but once in - that individual has the same access as the host program to all the internal






42. A special substance - also called thermal paste or heat sink compound - that increases the heat conductivity between a fan or heat sink and a chip.






43. A file system used by operating systems for organizing - reading - and writing optical discs.






44. An early technology for increasing the performance of DRAM.






45. A wireless network standard that uses the 2.4 GHz band at a speed of up to 54 Mbps. It is downward-compatible with 802.11b.






46. Aka point-to-point protocol.






47. Aka dynamic RAM.






48. Aka peripheral component interconnect.






49. A magnetic mass storage device primarily used for backing up data from computers.






50. A type of riser card that connects directly into a motherboard and adds no additional functionality of its own - but extends the expansion bus and allows expansion cards to be added in a different physical orientation.
