1. A drive that can write either to CD-R discs or to specially designed CD-RW discs. In the case of the CD-RW discs - the drive can write more than once to the same portion of disc - overwriting old data.






2. A method of memory error-checking that is more sophisticated than parity checking. Like parity checking - it adds an extra bit per byte. In addition - software in the system memory controller uses an algorithm to both detect and correct errors.






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






4. The cellular network standards used by Verizon and Sprint-Nextel.






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






6. The traditional transmission system for television video signals - which combines the color and brightness information with the synchronization data into one signal. The TV circuitry then separates the two signals from the composite signal.






7. A new level of an operating system with major changes to the core components.






8. A set of technologies that allow voice transmission over an IP network






9. A special-purpose computer designed for a certain task and installed within a device.






10. A now-obsolete type of rechargeable battery used in laptops and other portable devices - replaced by lithium-ion batteries.






11. Aka Compact Disc-Read-Only Memory.






12. A compartment in a portable computer's case that holds a single media device that can be swapped with another. For instance - you may swap an optical drive - a secondary hard drive - or a floppy drive into and out of a single bay.






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

15. Aka S-Video.






16. A type of switched network used by phone companies.






17. Aka access control list.






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






19. A mat that provides a path to ground for a static charge and is designed for the desktop or floor of a workspace. One placed on the workbench reduces the risk of electrostatic discharge for components placed on it - while one placed on the floor prov






20. Aka Rambus Dynamic RAM.






21. A service that manages Microsoft NetBIOS names for a Windows network. This service is becoming obsolete - as Windows has moved to DNS for naming and name service.






22. Aka nickel-cadmium.






23. Aka pin grid array.






24. The first physical sector on a hard disk - which contains the initial boot program that the BIOS loads into memory during bootup. It also contains the partition table.






25. A device that takes video output and projects it onto a screen for viewing by a larger audience.






26. An Advanced Options choice that will temporarily disable the Automatically Restart option on the Advanced page of System Properties.






27. A local bus designed for video only - it provides a direct link between the processor and the video card - giving the video card direct access to main memory.






28. A handheld device used to measure electrical resistance - voltage - and/or current.






29. The circuit board in a computer to which all other components directly or indirectly connect. Also called a mainboard - system board - mobo - or planar board.






30. This attack occurs when someone sends a large number of requests to a server - overwhelming the server so it stops functioning on the network.






31. A file used by Windows for virtual memory. Also called the swap file. The actual filename in Windows is PAGEFILE.SYS.






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






33. Sony-Philips digital interface format






34. A set of wires used by data traveling into and out of a processor.






35. A socket for a PGA CPU that has a retention lever as well as contacts to match the number of pins on the CPU. The lever is used to attach the CPU to the socket in a manner that does not require force to insert or to remove the CPU.






36. A heat dissipation device - usually a passive metal object with a flat surface attached to a component - such as a chip.






37. A security feature introduced in Windows Vista to prevent unauthorized changes to Windows.






38. Aka network interface card.






39. A part of the NTFS file system used to store a transaction-based database - with all file accesses treated as transactions - and if a transaction is not complete - NTFS will roll back to the last successful transaction.






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






41. 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.






42. An expansion bus architecture that uses serial communications rather than the parallel communications of PCI. Also called PCI Express and PCI-E.






43. Aka hard disk drive.






44. The cellular network standards used by AT&T and T-Mobile.






45. Aka RAID 5.






46. An external serial bus standardized by the IEEE. Apple first developed it as FireWire. Other manufacturers call it i.link or Lynx. It can support up to 63 daisy-chained devices. Since the introduction of the faster update - IEEE 1394b - the original






47. In a laptop - a compartment that holds a single media device that is switchable with another.






48. A disc drive that uses laser technology to read and/or write to special discs.






49. Aka Wireless Fidelity.






50. In reference to a memory module - how much information the processor can access from or write to memory in a single cycle.
