Which statement correctly describes cache memory?

Cache memory is a type of volatile computer memory that provides high-speed data access to the processor and stores frequently used program instructions and data. Its primary function is to facilitate quicker access to data and instructions that are accessed repeatedly, which significantly speeds up overall system performance. When the CPU needs data, it first checks the cache memory before accessing main RAM. Because cache memory consists of faster storage technologies compared to RAM, it helps minimize the time taken for data retrieval, thereby reducing latency in processing tasks.

The other statements do not capture the essence of what cache memory does or its characteristics. Cache memory is faster than RAM (contrary to the first statement), typically smaller than primary RAM (which relates to the third statement), and it is actively involved in CPU calculations by providing the fast data and instructions the CPU needs to perform tasks (which addresses the fourth statement).
