True/False
Indicate on scantron whether the sentence or statement is true or false.
1. Memory usually consists of one or more chips on the motherboard or some other circuit board in the
computer.
2. Manufacturers state the size of memory chips and storage devices in terms of the number of bytes the chip or
device has available for storage.
3. Nonvolatile memory loses its contents when power is removed from the computer.
4. Volatile memory is permanent and nonvolatile memory is temporary.
5. Most business users who work with accounting, financial, or spreadsheet programs, voice recognition, and
programs requiring multimedia capabilities should have a maximum of 128 MB of RAM.
6. The access time (speed) of memory has no affect on the overall performance of a computer.
7. Some motherboards include all necessary capabilities and do not require adapter cards.
8. Manufacturers often identify cables by their connector types to assist users with purchasing a cable to connect
to a peripheral.
9. Most personal computers have at least one serial port, one parallel port, and two USB ports.
10. USB supports hot plugging and Plug and Play, which means users can attach peripherals while the computer
is running.
11. Depending on the type of SCSI, which stands for small computer system interface, users can daisy chain
either up to 7 or 15 devices together.
12. The larger the number of bits handled by the bus, the slower the computer transfers data.
13. A system bus allows the processor to communicate with peripherals.
14. The current local bus standard is the VESA local bus (Video Electronics Standards Association local bus)
because it is more versatile than the PCI local bus.
15. The type of power from a standard wall unit is suitable for use with a computer, which requires an alternating
current (AC) of 115 to 120 volts.
Multiple Choice
Identify on scantron, the letter of the choice that best completes the statement or answers the question.

a. 32
c. 128
b. 64
d. 256
Bluetooth™ technology is ____.
a. similar to a USB port in that it can connect multiple types of devices that require faster
data transmission speeds
b. a special high-speed parallel port that allows users to attach peripherals such as disk drives
and printers
c. a special type of serial port that connects the system unit to a musical instrument
d. an alternative to IrDA that uses radio waves to transmit data between two devices
The wider the bus, the ____ the transfer of data.
a. greater the number of transfer steps required and the slower
b. greater the number of transfer steps required and the faster
c. fewer the number of transfer steps required and the slower
d. fewer the number of transfer steps required and the faster
The ISA bus (Industry Standard Architecture bus) is ____.
a. the most common and slowest expansion bus
b. a bus designed by Intel to improve the speed with which 3-D graphics and video transmit
