1. A parallel interface standard that supports bidirectional communication and transfer rates of up to 2 MBps.






2. A device used with a laptop. The port replicator remains on the desktop with external devices connected to ports on it. A laptop then needs only one connection to the port replicator to have access to the peripherals.






3. A security service in which authentication credentials are encrypted (user name and password) before transmission over a network.

5. Aka Advanced Technology eXtended.






6. A set of skills - behaviors - and attitudes to use when listening to another person.






7. One of the two prevailing CPU manufacturers.






8. A RAM standard that replaces the original DDR2 standard and requires far less power - while providing almost twice the bandwidth. A stick of DDR3 SDRAM has 240 pins - but is keyed so it will not fit into a socket designed for DDR2. DDR3 SO-DIMMs have






9. Aka read-only memory.






10. Microsoft's product activation program.






11. A version of the FAT file system used by hard drives and some flash drives (thumb drives - etc.) - using a 32-bit file allocation table.

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






14. An LCD display using an old technology that has a grid of horizontal and vertical wires with a transistor at the end of each wire. When two transistors (one at the x-axis and one at the y-axis) send voltage along their wires - the pixel at the inters






15. In fiber-optics - a single light wave passing down a cable.






16. A metal plate behind the front of a CRT monitor that focuses the electron beams from the gun.






17. RAM that doubles the rate of speed at which a standard SDRAM can process data. Also called DDR and DDR1. A stick of DDR1 SDRAM has 184 pins.

24. The disruption of signal transmission caused by the radiation of electrical and magnetic fields. Electric motors are a common source of EMI.






25. A CPU component that manages the CPU cache.






26. 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






27. A disk that uses basic storage - which means that it uses the partition table in the master boot record (MBR) to define disk partitions.






28. Aka capture card.






29. An input device that uses a stylus. Available as an external device - it uses touch screen technology and is usually at least the size of a sheet of paper. Also called a digitizer.






30. A digital display interface standard developed by the Video Electronics Standards Association that supports both video and audio signals - contains HDCP copy protection - and is unique because it is royalty-free to manufacturers.






31. A long-established fiber-optic WAN technology.






32. Used to represent the chrominance signal in S-Video.






33. The IBM branded name for a pointing stick or track point.






34. The file system component in the FAT file system in which the OS creates a table that serves as a map of where files reside on disk. Also called the FAT table.






35. Aka customer premises equipment.






36. 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.






37. The EXPLORER.EXE program. This program supports the entire Windows GUI. If EXPLORER.EXE is called up from inside the GUI - it opens a window for browsing your local disks and files.






38. A group of features in the system BIOS - the chipset - the operating system - device drivers - and the individual components that enable efficient use of power in a computer.






39. A Windows wizard that sets options for starting and running a specific old program that will not otherwise run properly in Windows.






40. 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.






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






42. A circuit card in a PC that controls the output to the display device(s).






43. Digital versatile disc (DVD) discs that can be written to - but data cannot be overwritten. This standard is newer than DVD-R. This term also refers to the drives that can write to these discs.






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






45. Aka virtual circuit.






46. 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.






47. The oldest of the Wi-Fi encryption standards. It uses 64- or 128-bit encryption that is easily broken. It does not encrypt the actual data in a packet - and it does not perform user authentication on a packet.
