MCQ
Q.
2 MB cache memory in bytes, equivalent to which of the following:
Correct Answer: A
The correct answer is 2 * 1024 * 1024 Bytes.
- One thousand and twenty-four kilobytes (1024 KB) is equal to one megabyte (1 MB), where 1 MB is 10242 bytes.
- So 2 Mb equals to 2 * 1024 * 1024 Bytes.
Key Points
- The cache memory
- The cache memory is located very close to the CPU, either on the CPU chip itself.
- It can be located on the motherboard in the immediate vicinity of the CPU.
- So data can be read from it (and written to it)more quickly than with normal RAM.
Additional Information
- Cache
- A cache is a special storage space for temporary files that makes a device, browser, or app run faster and more efficiently.
- There are three general cache levels:
- L1 cache, or primary cache:
- It is extremely fast but relatively small and is usually embedded in the processor chip as CPU cache.
- L2 cache, or secondary cache:
- It is often more capacious than L1.
- Level 3 (L3) cache
- It is a specialized memory developed to improve the performance of L1 and L2.
- L1 cache, or primary cache:
