Which computer memories has the shortest access time?
Usually the register set memory. The L1 cache may be as fast.
What is memory access time?
The time required by a processor to access data or to write data from and to memory chip is referred as access time.

Cache memory enhances?
memory access time.
How do you calculate memory access time?
Memory access time can be calculated using the formula: Memory Access Time = Hit Time + (Miss Rate × Miss Penalty). Here, the hit time is the time taken to access data from cache when it is found, while the miss rate is the frequency of cache misses. The miss penalty is the time required to retrieve data from the main memory when it is not available in the cache. By combining these factors, you can estimate the overall memory access time.
Which of the memory has shortest access time?
The processor registers! Relatively, they are very small (a register on an Intel 32-bit processor is only 4 bytes large!) but they are very fast. Programs use them to store the part of data they are working on and some memory addresses.
What is the formula to calculate the average memory access time in a computer system?
The formula to calculate the average memory access time in a computer system is: Average Memory Access Time Hit Time Miss Rate x Miss Penalty
How does the access time of storage compare with the access time of memory?
access times from memory is 200,000 times faster than access times from storage devices due to the mechanical movement involved.
What is a memory performance?
it is defined by access time and cycle time
Is access time of memory is slow compared with the access time of storage?
access times from memory is 200,000 times faster than access times from storage devices due to the mechanical movement involved.
What is the general relationship among access time memory cost and capacity?
Faster access time, greater cost per bit; greater capacity, smaller cost per bit; greater capacity, slower access time. As a general rule (but there are exceptions) the greater the capacity of a memory the longer the access time. For a higher cost the access time of a given capacity memory can usually be shortened some. As a general rule (but there are exceptions) the greater the capacity of a memory the total memory cost increases, but the memory cost per bit decreases.
What is data memory?
cache memory refreshes instantly so access time is faster
