Accepted Answer

RAM (Random Access Memory) is the most common type of volatile memory, which means it loses its stored data when the power is turned off. ROM (Read-Only Memory) and Flash memory are non-volatile memory types that retain their data when power is turned off. CMOS (Complementary Metal-Oxide Semiconductor) is a technology used in chip manufacturing and is not a type of memory.

Question 10

Which of the following is a cache separate from the processor chip on the motherboard?
A) L1 cache
B) L2 cache
C) L3 cache
D) L4 cache

Accepted Answer

L3 cache is often separate from the processor chip and located on the motherboard, whereas L1 and L2 caches are typically integrated directly into the processor chip. L4 cache is less common and can also be separate.

Question 11

Which of the following is a type of nonvolatile memory that can be erased electronically and rewritten, similar to EEPROM?
A) Flash memory
B) L1 cache
C) firmware
D) microcode

Accepted Answer

Flash memory is a type of nonvolatile memory that can be electronically erased and rewritten, similar to EEPROM.

Question 12

Which of the following is a kind of ROM chip that contains permanently written data, instructions, or information that is recorded when the chip is manufactured?
A) L1 cache
B) Flash memory
C) firmware
D) microcode

Accepted Answer

Firmware is a type of ROM chip that contains permanently written data, instructions, or information that is recorded when the chip is manufactured. L1 cache and microcode are not types of ROM chips, while flash memory can be rewritten multiple times.

Question 13

Double Data Rate SDRAM (DDR SDRAM) chips are even faster than SDRAM chips because which of the following is true?
A) They transfer data twice for each clock cycle.
B) They are synchronized to the system clock.
C) They do not have to be re-energized as often.
D) They use pipelining techniques.

Accepted Answer

Double Data Rate SDRAM (DDR SDRAM) chips transfer data twice for each clock cycle, making them faster than SDRAM chips. They are also synchronized to the system clock and use pipelining techniques, but neither of these factors directly contributes to their increased speed. Additionally, they do not necessarily have to be re-energized less often than SDRAM chips.

Question 14

The role of memory to store both data and programs is known as which of the following concepts?
A) stored program
B) random memory
C) ROM
D) store and send

Accepted Answer

The concept of storing both data and programs in memory is known as the stored program concept. This is a fundamental concept in computing, as it allows computers to execute complex programs by storing them in memory and accessing them when needed. ROM (read-only memory) refers to a type of memory that cannot be modified once it is programmed, while random memory (RAM) is a type of memory that is used for temporary storage and is volatile, meaning it is erased when the computer is turned off. "Store and send" is not a recognized concept in computer memory.

Question 15

Which of the following flash drives is a flash memory device that plugs in a port like the one shown in the accompanying figure on a computer or portable device?
A) peripheral
B) fixed
C) embedded
D) USB

Accepted Answer

A USB flash drive is a flash memory device that plugs into a USB port on a computer or portable device.

Question 16

Which of the following is true of synchronous DRAM (SDRAM) chips?
A) They transfer data twice for each clock cycle, when compared to DRAM.
B) They are synchronized to the system clock.
C) They do not have to be re-energized as often as DRAM chips.
D) They use pipelining techniques.

Accepted Answer

Synchronous DRAM (SDRAM) chips are synchronized to the system clock, allowing for faster and more efficient transfer of data compared to asynchronous DRAM (DRAM). Option A is incorrect as SDRAM transfers data once per clock cycle, but does so on both the rising and falling edges of the clock signal, effectively doubling the transfer rate. Option C is incorrect as SDRAM requires regular refreshing to maintain data, just like DRAM. Option D is incorrect as pipelining techniques are not explicitly used in SDRAM chips.

Question 17

Which of the following cards is a removable flash memory device?
A) cached
B) USB
C) integrated
D) memory

Accepted Answer

A memory card is a removable flash memory device used for storing digital information.

Rambus DRAM (RDRAM) chips are another type of DRAM chips that are much faster than SDRAM chips because which of the following is true?
A) They transfer data twice for each clock cycle.
B) They are synchronized to the system clock.
C) They do not have to be re-energized as often.
D) They use pipelining techniques.

Accepted Answer

RDRAM chips use pipelining techniques, which allow them to process multiple instructions simultaneously, increasing their speed compared to SDRAM chips.
