1. A physical area where a Wi-Fi network connects to the Internet.






2. Aka demilitarized zone.






3. The smallest laptop type - weighing less than 3 pounds. Aka also netbook and mini-notebook.






4. 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.






5. A protocol used with WPA wireless encryption that was broken by hackers.






6. The act of discovering the cause of a problem and correcting it.






7. A file attribute set by the OS when a file is created or modified. Backup software often removes this attribute when backing up a file in order to mark it as a backed-up file.






8. The Windows Vista and Windows 7 tool for gathering and viewing performance data involving memory - disks - processors - network - and other objectives.






9. A technology for ROM that can be reprogrammed using special software.






10. 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.






11. 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.






12. Aka Internet service provider.






13. A set of behaviors including active listening and active speaking that shows you are fully engaged in the conversation and encourages the other person to also communicate in a positive manner.






14. 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.






15. Aka complementary metal-oxide semiconductor.






16. A specialized type of scanner that reads bar codes - which are patterns of bars of varying widths printed on labels or directly on items. The bar pattern is converted into a numeric code that is transmitted to a computer as data.






17. Microsoft's product activation program.






18. The smallest laptop type - weighing less than 3 pounds. Aka also netbook and mini-notebook.






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






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






21. Aka Gigabit Ethernet.






22. Signals broadcast through the air.






23. 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.






24. Aka optical character recognition.






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






26. A hard drive interface that transfers data in parallel. EIDE and ATAPI drives attach to the PATA interface.






27. Aka digitizing tablet.






28. The proportion between an image's width and height. Traditional CRT monitors have an aspect ratio of 4:3. Widescreen displays have an aspect ratio of 16:9.






29. A tool for testing if a cable can connect properly end-to-end and to determine if a cable has a short. These tools are available for a variety of cable types.






30. A connector that is slightly larger than an RJ-11 connector and contains eight wires. RJ-45 connectors most commonly attach twisted-pair cables to Ethernet network cards.






31. A metal strip used to cover an empty slot in order to preserve the correct air flow and keep dust out.






32. Aka Spam over Instant Messaging.






33. The logical structure on disk that allows the operating system to save and retrieve files. Examples of file systems are FAT and NTFS. Both of these file system have different versions - such as FAT12 - FAT16 - FAT32 - and NTFS 4.0 and NTFS 5.0.






34. Aka front side bus.






35. A subprotocol of TCP/IP used for connectionless communications in which each packet is sent without establishing a connection.






36. In a Wi-Fi network - the networking mode that allows peer-to-peer communications without the use of a centralized wireless hub - called a wireless access point (WAP).






37. A TCP/IP protocol developed as a solution to the dwindling number of IP addresses on the Internet and that also serves to hide IP addresses on a private network from the Internet.






38. A communications network made up of personal computing devices - such as computers - telephones - and personal digital assistants.






39. Aka low-voltage differential (LVD).






40. Aka Encrypting File System (EFS).






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






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






43. A printer that includes one or more other functions - such as a scanner and fax machine.






44. A CPU containing two CPU cores.






45. An LCD technology based on thin-film transistor (TFT) technology. An active matrix display has a transistor at every pixel - which enables much quicker display changes than passive matrix displays and produces a display quality comparable to a CRT.






46. Aka boot record.






47. A utility in Windows XP and Windows 2000 for gathering and viewing performance data involving memory - disks - processors - networks - and other objectives.






48. An organization that created several PC standards - including the VGA connector.






49. A DVI mode that supports both analog and digital video signals.






50. A card that fits into the PC Card interface - including both PC Card and CardBus cards. This type measures 85.6 millimeters long by 54 millimeters wide and measures 10.5 mm thick.
