  • 1

    Ramdom Access Memory (RAM) is an example of volatile storage media. It requires a continuous flow of electricity to preserve its contents; therefore, all data stored in RAM lasts only while the power is on.

    True

  • 2

    SDRAM’s backward compatibility feature provides a convenient way to build PC’s utilizing different types of SDRAM modules.

    False

  • 3

    Which CPU technology places the pins on the motherboard instead of the chip?

    LGA

  • 4

    Which of the following is required to take advantage of the performance benefits offered by multi-channel memory architecture?(select all that apply)

    Installing memory modules of the same capacity, Installing modules and appropriate memory slides (slots of matching color) On the motherboard, Installing memory modules of matching speeds, Installing memory modules of matching types

  • 5

    Certain types of RAM use an additional bit in order to detect whether a data error has occurred. This extra bit is used to store information about how many bits are set to a value of one in a given string of data (typically 1 byte). Examining the value of this additional bit at different stages of processing allows to detect, rather the data has been corrupted. What is the name of this extra bit?

    Parity Bit
