Which of the following BEST describes access time for RAM?
It is the time from the instant that an
address is placed on the data bus to the instant that data have been transferred.
It is the time delay to reach the required data due to too many addresses in RAM.
It is the time from the instant that an
address is presented to the memory to the instant that data have been made available for use.
It is the duration between the start and end time of processing data.
Which of the following about cache memory is FALSE?
The cache contains a copy of portions of RAM.
Cache design for high-performance computing is the same as it is for a basic desktop PC.
The L2 cache is slower and larger than the L1 cache.
It is faster and more costly than RAM.
What is the term tag in cache mapping refer to?
The minimum unit of transfer between cache and main memory.
A replacement algorithm that replaces the block in the set that has been in the cache longest.
The number of data bytes contained
in a line.
A portion of a cache line that is used for addressing purposes.
Which of the following about non-volatile memory is TRUE?
EPROM, PROM, and flash memory are non-volatile.
It can read and write data.
It is also known as temporary storage.
Power must be constantly supplied to the memory to retain data.
What is the advantage of RAID technology?
Allowing easier incremental increases in capacity.
Enabling simultaneous access to data from multiple drives.
Improving I/O performance.
All of the above.
Which of the following about bus is FALSE?
It provides pathways between components in the
computer system.
It consists of data lines, address lines, and control lines.
Its basic function is to store and execute programs.
It is a shared transmission medium.
The bus interconnection structure supports which transfer?
Processor to memory
I/O to or from memory
Memory to processor
All of the above
Which of the following BEST describes the data bus?
Data lines that designate the source or destination of the data.
Data lines that provide a path for moving data among system modules.
Data lines to control the access and the use of the bus.
All of the above.
What is meant by bus width?
How much data that can be accessed or transmitted at a time.
How fast a memory address can be accessed by the processor.
How fast a group of bits can be transmitted each second.
How much data that can be stored in the computer memory.
Which of the following about PCIe is TRUE?
Video cards are the only type of PCIe card.
PCIe 4.0 has a lower bandwidth than PCIe 3.0.
PCIe devices attach directly to the computer via USB ports.
The more number of direct connections provided by a PCIe slot, the better the hardware can perform.
