Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. The role of the first EIDE drive on a PATA channel.






2. A video mode that most often consists of a combination of 640






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






4. A parallel port mode that has the same performance as ECP but is used with parallel devices other than printers and scanners.






5. The hardware architecture - including the CPU - BIOS - and chipset.






6. A dark spot on an LCD screen caused when a transistor is permanently off.






7. 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






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






9. Sony-Philips digital interface format






10. A term applied to a CPU - motherboard - or other components that conform to the Intel 32-bit x86 specification. Also referred to as 32-bit.






11. In a disk drive - the rotating shaft used to spin the disks.






12. A memory error-checking method in which the parity bit is used to ensure that the total number of 1s in the data stream is odd.






13. The worldwide network that carries traditional voice traffic.






14. 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.






15. Aka microcode.






16. 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.






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






18. A group of networking standards created by the IEEE 802.3 subcommittee.






19. Aka digital video interface.






20. A raised area on an optical disc that is alternated with depressed areas to be interpreted as data.






21. A CPU containing four CPU cores.






22. The early standard developed by PCMCIA for credit-card-sized devices used in laptops.






23. A display device that contains a cathode ray tube and uses an electron gun to activate phosphors behind the screen at the front of the tub.






24. Any video adapter or monitor that exceeds the VGA standard in resolution and color depth with a maximum resolution of 1600






25. Also called striping with distributed parity or striping with interleave parity - this RAID method involves a set of disks in which every time data is written to disk - a portion is written to each disk in turn - creating a "stripe" of data across th






26. Memory that is accessible in any (random) order. Most of the memory in a PC is RAM.






27. Aka security auditing.






28. A RAM standard that replaces the original DDR standard. Using far less power than DDR1 - a stick of DDR2 SDRAM has 240 pins.






29. A cooling system that uses liquid to transfer heat away from components.






30. A process that runs "behind the scenes" with a low priority - does not require input - and rarely creates output.






31. Memory chips that use a special Rambus channel that has a data transfer rate of 800 MHz. A double channel width results in a 1.6 GHz data transfer. RDRAM sticks use special RIMM slots.






32. 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






33. One of many low-level instructions built into the control unit of a CPU. Also called a microprogram.






34. The component that provides power for all components on the motherboard and internal to the PC case. Also called a power supply unit (PSU).






35. Also called 1000Base-T - this networking standard supports speeds up to 1 Gbps.






36. A WAN connection that uses an analog modem rather than a network card and uses standard phone cables rather than network cables.






37. Aka Media Access Control (MAC) address.






38. The Microsoft Website from which you can download updates to Windows.






39. The use of deceit and trickery to persuade someone to hand over money or valuables.






40. A method for supporting up to 8.3 GB capacity hard drives. Both the BIOS and hard drive system must use LBA.






41. A special substance - also called thermal paste or heat sink compound - that increases the heat conductivity between a fan or heat sink and a chip.






42. The act of safely installing/uninstalling or attaching/removing a device while a computer is up and running.






43. A name used by the Windows operating systems to identify any parallel port.






44. Aka logical block address.






45. The practice of applying a digital signature to device driver code.






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






47. A portion of a computer's chipset that controls communications between the CPU and such I/O busses as USB - IDE - PS2 - SATA - and others.






48. An LCD display that accepts a digital signal. Early LCD displays accepted an analog signal and converted it to digital internally.






49. Aka Advanced Technology eXtended.






50. Authentication is validation of a user account and password that occurs before the security components of Windows will give the user access to the computer.
