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






2. The role of the second EIDE drive on a PATA channel.






3. A memory module (stick) that installs into matching DIMM sockets found on many motherboards. The word "dual" refers to the separate pins or connections on both sides of the module and socket.






4. An improved version of WPA that does not support older network cards and offers both secure authentication and data encryption. It uses EAP for a variety of authentication methods






5. The difference in value between a display's brightest white and darkest black. Modern LCD displays have a contrast ratio of 500:1 or greater.






6. A type of memory checking in which every eight-bit byte of data is accompanied by a ninth bit (the parity bit) - which is used to determine the presence of errors in the data. The two types of parity are odd and even.






7. A set of standards for imaging devices - such as scanners and cameras - that is used in drivers and other software for these devices.






8. The original version of the IEEE 1394 standard that supports speeds up to 400 Mbps.






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






10. A cooling fan mounted directly on the case - as opposed to a power supply fan - which is inside the power supply.






11. Aka IEEE 1394.






12. A wireless data encryption standard based on the IEEE 802.11i security standard. It issues keys per-user and per-session and includes encryption key integrity checking. It uses Temporal Key Integrity Protocol (TKIP).






13. A VESA standard for graphics adapters with a maximum graphics resolution of 1024






14. Audio connectors that use a 1/8" single pin plug.






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






16. The original digital discs created in 1995 for storing video.






17. Aka solid-state storage.






18. The traditional wired telephone network.






19. A drive used for reading from and writing to removable floppy disks. Also called FDD.

21. A 20- or 24- pin connector that supplies power from a PC's power supply to the motherboard.






22. One of the main protocols of the TCP/IP protocol suite - IP manages logical addressing of network packets so routing protocols can route the packets over the network.






23. Another name for a motherboard in a laptop.






24. A grouping of wires built into a PC that - based on certain protocols - transfers data - control signals - and power to printed circuit boards (adapter cards) that are plugged into connectors in the expansion bus. Technicians often use the termsexpan






25. The signal in a television transmission that contains the color of the image.






26. Showing consideration for others.






27. 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.






28. In an IP configuration - the address of the local router that acts as a gateway from the local network to other IP networks.






29. An early method for addressing the disparity between the drive geometry supported by PC BIOSs and the physical geometry of drives.






30. The protocol used to allow client computers to pick up e-mail from mail servers. The current version is POP3.






31. A plastic card - often the size of a credit card - that contains a microchip. The microchip can store information and perform functions - depending on the type of smart card. Some smart cards only store data - whereas others may have a variety of fun






32. Aka low-voltage differential (LVD).






33. Things used for authentication - such as something you know - something you have - or something you are. Authentication involves one or more of these factors and can - therefore - be one-factor - two-factor - or three-factor authentication.






34. A security account that exists in a local security accounts database.






35. A sleep mode that is available on any computer that supports ACPI power management. It conserves power while saving the desktop in RAM memory in a work state. To resume - you simply press the power button - and the desktop is quickly displayed.






36. Aka hacker.






37. Aka software firewall.






38. In the laser printing process - the stage in which the image is removed from the photosensitive drum so it can accept the next image.






39. A video interface - also called Super Video - that transmits video using two signals






40. A power management standard that includes all the power states of APM - plus two more. It also supports soft power.






41. 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.






42. Traditionally - this term only applied to the type of device described in the definition for analog modem. Now - it is also used for the digital devices in DSL and cable data communications.






43. A command-line utility - installed with the TCP/IP protocol suite - that is used to troubleshoot DNS problems by querying DNS name servers and displaying the results of the queries.






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






45. The code used to provide multiple language support to Windows.






46. Aka motherboard.






47. In Windows - a security account that contains one or more local user accounts - and when a computer is a member of a Windows domain - may also contain domain user or group accounts.






48. A file operation in which the file or folder remains in the source location - and a duplicate is created in the target (destination) location.






49. In a low-profile PC case - a card that plugs into a motherboard to allow other cards to be inserted at a right angle to the riser card and parallel to the motherboard. Also - a single expansion card containing multiple functions - such as modem - sou






50. Aka routing information protocol.
