D. 3 to 5V
10. What does ESD refer to?
A. Electronically safe device
B. Electrical static discharge
C. Electric surge protector
D. None of the above
Answers
1. D. The binary number 00000110 is the same as adding 22 (4) and 21 (2) to get 6. Take a look at “Reading binary numbers.”
2. C. A binary number consists of only 1s and 0s. An octal number has no digits higher than a 7; and this is obviously not a decimal number. Any number that has the characters A through F and 0 through 9 is a hexadecimal number. Check out “Working with hexadecimal numbers.”
3. A. The strength of an electrical current is measured with an ammeter in amps. Review “Counting electrons.”
4. A. ESD damage is far more common than any other damage inflicted by the repairperson or user. Look at “Don’t Give Me Any Static.”
5. B. Electrical resistance, or the amount of resistance in a conductor to the flow of electricity, is measured with an ohmmeter in ohms. See “Counting electrons.”
6. A, B, C, and D. Wear an ESD grounding strap when working all of these FRMs (field replaceable modules). The only part of the computer you don’t want to be grounded to is the Cathode Ray Tube (CRT) — see Chapter 12 for more information. Check out “Don’t Give Me Any Static.”
7. B. Household appliances operate on alternating current, but the computer operates on direct current. The power supply converts AC to DC. Take a look at “Switching from AC to DC.”
8. C. A00h is the same as 10 * 256 (162), or 2,560. Review “Converting hexadecimal numbers.”
9. B. It doesn’t take very much of an ESD charge to zap the internal components of a computer. Check out “Looking at the dark side of ESD.”
10. B. ESD is the abbreviation for either electrical static discharge or electrostatic discharge; both terms are used interchangeably. Zap over to “Don’t Give Me Any Static.”


Prep Test
1. Which of the following is not a common name for the primary printed circuit board in a PC?
A. Mainboard
B. Motherboard
C. Planar board
D. Systemboard
2. Which of the following are common motherboard form factors? (Choose three.)
A. Mother AT
B. AT
C. ATX
D. Baby AT
3. Which of the following motherboard form factors is nearly square?
A. Mother AT
B. AT
C. ATX
D. Baby AT
4. Which of the following FRMs does not get its size and shape specified in a form factor standard?
A. Power supply
B. System case
C. Memory
D. Motherboard
5. The feature used to resolve the speed differences of the CPU and RAM is
A. Disk cache
B. Main memory
C. Cache memory
D. Data bus
6. Which computer component contains the circuitry necessary for all components or devices to communicate with each other?
A. Motherboard
B. Adapter board
C. Hard drive
D. Expansion bus
7. Which statement best describes the purpose of the motherboard?
A. Supplies DC power to the peripheral devices
B. Interconnects the primary components of the PC
C. Executes all instructions of the PC
D. Stores and processes the data of the PC
8. The principle of locality reference says that
A. The next data to be requested is the one before last
B. The hard drive should not be next to the CPU
C. The next data to be requested is the last one
D. The next data to be requested is located immediately following the last one
9. Level 1 cache is located where?
A. On the motherboard
B. On an adapter card
C. On the CPU
D. On the ROM BIOS
10. Cache memory is what type of memory?
A. DRAM
B. SRAM
C. Virtual memory
D. There is no standard memory type used for cache
Answers
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.”
