The correct answer is: C. Both locate and retrieve the data.
Access time is the time it takes for a computer to locate and retrieve data from its memory. It is usually measured in nanoseconds (ns) or microseconds (µs).
The access time of a computer memory is determined by a number of factors, including the type of memory, the speed of the processor, and the size of the data being accessed.
The type of memory is the most important factor in determining access time. Static RAM (SRAM) has the fastest access time, followed by dynamic RAM (DRAM). Flash memory has the slowest access time.
The speed of the processor also affects access time. A faster processor can access data from memory more quickly than a slower processor.
The size of the data being accessed also affects access time. Larger data sets take longer to access than smaller data sets.
Access time is an important factor in the performance of a computer. A computer with a fast access time can perform tasks more quickly than a computer with a slow access time.
Here is a brief explanation of each option:
- Option A: Locate the stored data. This is the first step in accessing data from memory. The computer must first locate the data in memory before it can retrieve it.
- Option B: Retrieve the stored data. This is the second step in accessing data from memory. Once the computer has located the data, it must then retrieve it from memory.
- Option C: Both locate and retrieve the data. This is the correct answer. Access time is the time it takes for a computer to locate and retrieve data from its memory.
- Option D: All of the above. This is incorrect. Access time is the time it takes for a computer to locate and retrieve data from its memory. It is not the time it takes to store data in memory.
- Option E: None of the above. This is incorrect. Access time is the time it takes for a computer to locate and retrieve data from its memory.
