QUESTIONS AND ANSWERS GRADED A+
◉F. Answer: A characteristic of ROM is that it is volatile.
(T/F)
◉T. Answer: RAM must be provided with a constant power supply.
(T/F)
◉T. Answer: The two traditional forms of RAM used in computers
are DRAM and SRAM.
(T/F)
◉T. Answer: A static RAM will hold its data as long as power is
supplied to it.
(T/F)
◉F. Answer: Nonvolatile means that power must be continuously
supplied to the memory to preserve the bit values.
(T/F)
,◉F. Answer: The advantage of RAM is that the data or program is
permanently in main memory and need never be loaded from a
secondary storage device.
(T/F)
◉T. Answer: Semiconductor memory comes in packaged chips.
(T/F)
◉T. Answer: All DRAMs require a refresh operation.
(T/F)
◉T. Answer: A number of chips can be grouped together to form a
memory bank.
(T/F)
◉T. Answer: An error-correcting code enhances the reliability of the
memory at the cost of added complexity.
(T/F)
◉F. Answer: DRAM is much costlier than SRAM.
(T/F)
,◉F. Answer: RDRAM is limited by the fact that it can only send data
to the processor once per bus clock cycle.
(T/F)
◉T. Answer: The prefetch buffer is a memory cache located on the
RAM chip.
(T/F)
◉F. Answer: The SRAM on the CDRAM cannot be used as a buffer to
support the serial access of a block of data.
(T/F)
◉D. Answer: Which properties do all semiconductor memory cells
share?
A. They exhibit two stable states which can be used to represent
binary 1 and 0
B. They are capable of being written into to set the state
C. They are capable of being read to sense the state
D. All of the above
◉A. Answer: One distinguishing characteristic of memory that is
designated as _________ is that it is possible to both to read data from
the memory and to write new data into the memory easily and
rapidly.
, A. RAM
B. ROM
C. EPROM
D. EEPROM
◉D. Answer: Which of the following memory types are nonvolatile?
A. Erasable PROM
B. Programmable ROM
C. Flash memory
D. All of the above
◉B. Answer: In a _________, binary values are stored using traditional
flip-flop logic-gate configurations.
A. ROM
B. SRAM
C. DRAM
D. RAM
◉C. Answer: A __________ contains a permanent pattern of data that
cannot be changed, is nonvolatile, and cannot have new data written
into it.
A. RAM
