The storage space in the computer, where instructions are stored and data is processed is called memory.

Answer: Cache memory is the fastest memory.

Cache memory stores the data that is frequently used by the CPU. It has a faster access time where data is temporarily stored for faster access. It fetches and executes instructions. Level 1 cache is the next fastest form of cache memory located on the CPU itself. The memory that is used for cache memory is Static random-access memory (SRAM).

Basic Details on Cache Memory

Following is the basic information related to the Cache memory:

  • It has three main parts namely a data section, a directory store, and status information.

  • They are present for each cache line.

  • It also stores the data read from the main memory.

  • It stores the information in the data section.

  • It is used to reduce the average time to access data from the Main memory.
