  4. Which of the following FRMs does not get its size and shape specified in a form factor standard?

    1. Power supply

    2. System case

    3. Memory

    4. Motherboard

  5. The feature used to resolve the speed differences of the CPU and RAM is

    1. Disk cache

    2. Main memory

    3. Cache memory

    4. Data bus

  6. Which computer component contains the circuitry necessary for all components or devices to communicate with each other?

    1. Motherboard

    2. Adapter board

    3. Hard drive

    4. Expansion bus

  7. Which statement best describes the purpose of the motherboard?

    1. Supplies DC power to the peripheral devices

    2. Interconnects the primary components of the PC

    3. Executes all instructions of the PC

    4. Stores and processes the data of the PC

  8. The principle of locality reference says that

    1. The next data to be requested is the one before last

    2. The hard drive should not be next to the CPU

    3. The next data to be requested is the last one

    4. The next data to be requested is located immediately following the last one

  9. Level 1 cache is located where?

    1. On the motherboard

    2. On an adapter card

    3. On the CPU

    4. On the ROM BIOS

  10. Cache memory is what type of memory?

    1. DRAM

    2. SRAM

    3. Virtual memory

    4. There is no standard memory type used for cache


  1. C. Okay, so this is a trick question. Planar board is an older term that was once used for passive backplane boards. Don’t expect to see planar on the exam. See “By any other name, it’s still mother.”

  2. B, C, D. Now, don’t go thinking that all the questions on the A+ exams are this easy. Mother AT is obviously not a form factor, but it’s all easy and obvious when you know the material. Review “Motherboard form factors.”

  3. B. The AT motherboard is 12 inches wide x 11–13 inches tall. Look it up in “AT form factor.”

  4. C. Typically the form factor includes the size and shape and fit of the case, power supply, and motherboard. See “Motherboard Sizes, Shapes, and Styles.”

  5. C. Cache memory holds the data that the CPU is likely to use next, which speeds up the transfer to the CPU, hopefully eliminating CPU wait states. Review “Caching In on a Good Thing.”

  6. A. The bus structures are located on the motherboard/systemboard. Check out “Understanding the Motherboard.”

  7. B. The motherboard is the platform that interconnects all of the primary components of the PC. Take a look at “Understanding the Motherboard.”

  8. D. The caching system uses the principle that the next data is likely the data located immediately after the last one requested. See “Caching in operation.”

  9. C. Level 1, also known as internal, cache is located on the CPU, which is also called on the die. Look over “Caching levels inside and outside the CPU.”

  10. B. Cache memory is usually a small amount of SRAM. Review “Thanks for the cache memories.”
