What is a cache miss?

What is a cache miss?

A cache miss occurs when the data requested is not found in the cache, requiring a fetch from slower memory.

What are the types of cache misses?

There are three types: compulsory, capacity, and conflict misses. Each has different causes and implications.

How can I reduce cache misses?

You can reduce cache misses by optimizing data locality, increasing cache size, and using better caching algorithms.

What impact do cache misses have on performance?

Cache misses can significantly slow down performance, as accessing main memory is much slower than accessing cache.

Can you give an example of a cache miss in action?

Sure! For instance, if a CPU needs data that was recently used but is no longer in the cache, it experiences a cache miss.
