16. The term used for dynamic space allocation that can be formatted with a file system.






17. Aka enhanced parallel port (EPP) mode.






18. The first type of RAM available. It is very fast - compared to DRAM - but also very expensive.






19. Aka capture card.






20. Dual inline package. A very tiny slide that indicates two states. Motherboard and other circuit cards often have one or more groupings of DIP switches for configuring options.






21. 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.






22. One or more chips designed to work closely with the CPU. Two parts of this chipset are the Northbridge and the Southbridge.






23. Aka lithium-ion (Li-ion) battery.






24. Device that stores digital data on magnetized media - such as floppy disks - the metal platters in hard disk drives - and magnetic tape media used in tape drives.






25. Aka front side bus.






26. A file attribute that is given to a file to indicate it should not be visible in Windows Explorer unless View settings override the attribute and allow the file to be shown.






27. Aka Internet Control Message Protocol.






28. The practice of forcing a CPU or other computer component to run at a higher clock rate than the manufacturer intended.






29. The classic PC serial port that complies with the Recommended Standard-232 (RS-232) in its circuitry - cabling - and connector design - and transfers data one bit at a time.






30. A term used for CPU packaging that indicates that a chip has columns and rows of pins.






31. Aka Ethernet.






32. A CPU containing four CPU cores.






33. In the domain name system - a name that is registered under a top-level domain - such as mcgraw-hill.com or microsoft.com.






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






35. Aka digital video interface.






36. An option available in the Windows XP Backup program for recovering from damage that prevents the operating system from starting. It replaced the Emergency Repair Disk (ERD) process in Windows 2000.






37. A drive on a computer that can play music CDs and read data CDs - but cannot write to CDs.






38. The former name of the Parallel AT Attachment (PATA) interface standard.






39. Aka display power-management signaling.






40. A large burst of electromagnetic energy - as from a nuclear explosion - that has the potential to damage communications and power lines within a large geographic area - depending on the size and location of the pulse.






41. A type of computer firmware that is responsible for informing the CPU of installed devices and how to communicate with them.






42. Aka wireless access point.






43. A protocol for computer-to-computer (host-to-host) transfer of files over a TCP/IP network - regardless of the operating system in use.






44. A multi-GPU solution developed by NVIDIA.






45. Also called mirroring - this RAID array type provides fault tolerance because all the data is written identically to the two drives in the mirrored set.






46. Aka Small Computer System Interface.






47. A network that covers a relatively small area - such as a building - home - office - or campus. The typical distances are measured in hundreds of meters.






48. Aka FAT file system.






49. A pointing device built into some laptop keyboards. It appears to be a very tiny joystick-type button that barely protrudes above the level of the keys.






50. In the laser printing process - this is the step in which the cover on the printer's toner cartridge is opened and the toner particles are attracted to the relatively less negatively charged areas of the drum.
