Cache uses a faster type of memory.
|
|
Frequently used instructions are stored in cache.
|
|
As cache is closer to the processor than RAM, fetches are completed in less time.
|
|
Cache is located closer to the processor.

Detailed explanation-1: –The more cache the CPU has, the less time the computer spends accessing slower main memory and as a result programs may run faster.
Detailed explanation-2: -A cache’s primary purpose is to increase data retrieval performance by reducing the need to access the underlying slower storage layer. Trading off capacity for speed, a cache typically stores a subset of data transiently, in contrast to databases whose data is usually complete and durable.
Detailed explanation-3: -Cache memory is an extremely fast memory type that acts as a buffer between RAM and the CPU. It holds frequently requested data and instructions so that they are immediately available to the CPU when needed. Cache memory is used to reduce the average time to access data from the Main memory.
Detailed explanation-4: -Cache decreases data access times, reduces latency and improves input/output (I/O).
