    C. L1, L2, L3

    D. L1, L2, L3, L4

    Answer: B. L1 and L2 cache were built into the Pentium Pro CPU chip. Older Pentium chips have only a L1 cache, and newer chips may also have a L3 cache. No chips use L4 cache as yet.

  18. To speed up the use of frequently used programs?

    A. Upgrade CMOS

    B. Phlash BIOS

    C. Increase RAM

    D. Install more L1 Cache

    Answer: C. Increasing RAM reduces the need for the PC to swap files from RAM to slower fixed disk virtual RAM. There are no CMOS upgrades. Phlashing the BIOS cures hardware problems, but doesn't impact performance. Added L1 cache cannot be installed because it is built into the CPU chip.

  19. Software installed on a PC hardware component is known as:

    A. BIOS

    B. RAM

    C. Firmware

    D. CMOS

    Answer: C. Firmware is software encoded in ROM or NVRAM and installed on a hardware component. BIOS is a very specific type of firmware used to boot the PC. RAM is volatile memory and looses its contents when the PC is powered off. CMOS is a technology used to store the PC boot-up parameters.

  20. To manage expanded memory, a PC uses?

    A. EMM386.EXE




    Answer: A. The Expanded Memory Manager program is EMM386.EXE. HIMEM.SYS implements Extended Memory Specification (XMS), LOADHIGH.EXE loads programs into the upper memory blocks, and HIGHLOAD is not a program.

  21. Which OS first implemented plug-and-play installation features?

    A. Windows 3.x

    B. Windows 3.11

    C. Windows 95

    D. Windows 98

    E. Windows Me

    F. Windows 2000

    Answer: C. Windows 95 was the first OS to have significant plug-and-play hardware installation capabilities. Windows 3.x and 3.11 were not plug and play. They depended upon real mode DOS drivers to interface with PC hardware components. Windows 98, Windows Me, and Windows 2000 all followed Windows 95.

  22. All memory above the 1,024 KB boundary is called?

    A. Reserved memory

    B. Extended memory

    C. Conventional memory

    D. Expanded memory

    Answer: B. Extended memory is all memory above the 1,024 KB boundary. Any unused memory is labeled reserved memory. Conventional memory is below 1,204 KB. Expanded memory residing above the 1,024 KB boundary is created from extended memory, but extended memory is needed first or there is no expanded memory.

  23. Powering the PC off and then on constitutes a?

    A. Hard boot

    B. Soft boot

    C. Warm boot

    D. Medium boot

    Answer: A. Recycling power (off and then on) is called a hard boot because it kills all RAM contents. A warm boot is when CTRL + ALT + DELETE are pressed while the PC power remains on. This may be called a soft boot as well. There is no medium boot.

  24. The maximum MHz speed for a Pentium CPU chip is:

    A. 66 MHz

    B. 366 MHz

    C. 800 MHz

    D. 1.5 GHz

    E. 2.0 GHz

    F. 10 GHz

    Answer: D. This answer is good for 2001. However, in 2002, the answer may change to E. It is certain that, in time, answer F will become correct as well.

  25. The bus speed is the speed data on the system board is moving?

    A. True

    B. False

    Answer: B. The bus speed is measured as the clock speed of the bus. A bus may be 8 bits, 16 bits, 32 bits or 64 bits wide, so the data speed would be a 1X, 2X, 4X, or 8X multiplier of the bus speed.

  26. The common voltages found on system boards are?

    A. +/- 5 volts

    B. +/- 10 volts

    C. +/- 12 volts

    D. +/- 110 volts

    E. +/- 120 volts

    Answer: A and C. These are the voltages found on MLBs. The 10 volt and 110 volt amounts are not used in computers and are odd voltage levels. The AC line that powers a PC is 120 volts, but the power supply in the PC changes the 120 volts into 5 volts and 12 volts.

  27. VGA standard resolution is?

    A. 1,600 by 1,200

    B. 1,280 by 1,024

    C. 800 by 600

    D. 640 by 480

    Answer: D. Standard VGA resolution is 640 by 480. SVGA resolution is 800 by 600. The 17-inch, 18-inch, and 19-inch plasma panels have a resolution of 1,280 by 1,024. Most laptops and smaller flat panel displays support the XGA resolution of 1,204 by 768.

  28. How many devices can be connected to a single SCSI bus?

    A. 2

    B. 4

    C. 5

    D. 7

    Answer: D. Seven devices are most commonly connected to PC SCSI buses. The eighth connection is the SCSI controller board. Server SCSI buses can connect 15 devices.

  29. A serial mouse connector has how many pins?

    A. 6

    B. 9

    C. 15

    D. 25

    Answer: B. Serial mice connect into the 9-pin serial port on the rear of the PC. The PS/2 mouse connects into a 6-pin connector. The 15-pin connector is used to attach joystick controllers or monitors. Finally, the 25-pin connector is commonly the serial port on the rear of the PC.

  30. The PC parallel port D connector has how many pins?

    A. 15

    B. 25

    C. 34

    D. 50

    Answer: B. Parallel ports on the rear of a PC are 25-pin ports. Game controllers use 15-pin connectors, floppy disk drives use 34-wire cables, and SCSI connectors are 50-pin connectors.
