1. A term used by Microsoft for a peer-to-peer network in which each computer can be either a client or a server or both.






2. A menu that opens from the Start button on the taskbar.






3. In the laser printing process - a wire that passes a small positive charge to paper as it travels through the printer. This positive charge attracts the negatively charged toner particles on the drum to the paper.






4. Aka hyper threading.






5. 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).






6. A method for allocating disk space on hard disks in which configuration information for each dynamic disk is located on the disk space beyond the first physical sector. This configuration information is stored outside of any volume on the hard disk.






7. Aka Advanced Communications Riser.






8. A CPU containing two CPU cores.






9. A system resource that certain devices - such as sound cards and hard drives - can use to move data between the device and system RAM without involving the processor.






10. A wireless standard for using radio waves to communicate between devices. Class 3 Bluetooth devices (the most common) communicate at distances up to one meter.






11. Aka power-on self-test.






12. 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.






13. In router configuration - a term that is used to describe traffic that is allowed - as in allowing traffic using a certain port number through the router.






14. A type of rechargeable battery used in laptops and other portable devices.






15. Aka uninterruptible power supply.






16. An address that a DHCP client will assign to itself after requesting an address and failing to receive one from a DHCP server. The address it will assign is in the 169.254 /16 network - which is the range of addresses from 169.254.0.1 to 169.254.255.






17. A power supply standard that has both the 20-pin connector for the motherboard and a 4-pin 12 V connector.






18. A command-line tool installed with the TCP/IP protocol suite that is used for testing communications between two hosts.






19. A device that sits at the connection between networks and routes packets based on their logical destination addresses.






20. An obsolete video standard introduced with IBM PS/2 computers in the late 1980s. VGA had a maximum resolution of 720






21. A network in which all of the computers essentially operate as both servers (providing access to shared resources) and clients (accessing those shared resources).






22. Aka IEEE 1394.






23. An operating system that runs on a network server and provides file sharing and access to other resources - account management - authentication - and authorization services.






24. A power supply and motherboard feature that allows software to turn off a computer rather than only using a physical switch.






25. This attack occurs when a massive number (up to hundreds of thousands) of computers send DoS attacks to a server - making it unavailable.






26. The default Windows file system that includes many important features - including encryption and permissions.






27. 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.






28. An early technology for increasing the performance of DRAM.






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






30. 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.






31. A WAN connection that uses existing copper telephone wire for the communication circuit. To accomplish this - a DSL modem splits the existing phone line into two bands; voice transmission uses the frequencies below 4000 Hz - whereas data transmission






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






33. A key on a laptop that - when pressed along with the FN key - changes the laptop display brightness at the hardware level. On some laptops - when this key combination is pressed - a small brightness control panel will display on the screen. Use the u






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






35. The minimum disk space that a file can use - allocated in the file system.






36. A special disk used for recovering an OS failure in Windows 2000. It requires that you create the ERD while the system is healthy - and then use it - along with the Windows Setup CD - to repair Windows.






37. A Windows utility that allows you to create tasks that run automatically at the times you select.






38. A utility in Windows NT for gathering and viewing performance data involving memory - disks - processors - network - and other objectives.






39. Aka Static RAM.






40. 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.






41. A technology used by hard drives to speed up data transfers by using DMA channels.






42. Aka routing information protocol.






43. The area at the beginning of a disk formatted with the FAT file system. This area contains the boot record - FAT table - and root directory.






44. On a motherboard - the type and location of components - as well as the size of the board itself.






45. Aka Hypertext Transfer Protocol (HTTP).






46. Any writable mass storage device - removable or fixed in place.






47. A CPU technology that allows two threads to execute at the same time within a single execution core. This technology is considered to be partially parallel execution. Intel introduced it in the Pentium 4 Xeon CPU. Also known as simultaneous multithre






48. Aka RAID 5.






49. The specific requirements for the level of CPU - amount of memory - and size of the hard disk for the computer on which an operating system can be installed.






50. Aka logical block address.
