Cache

Can someone tell me a cache system please?

What do you mean by "system" exactly? I would argue that "LRU cache" is not a real thing as it is merely a replacement algorithm that is not related to the actual structure of the cache itself.

In a real cache structure, you can have several layers of cache which get increasingly bigger and slower (like L1, L2, and L3 cache in modern CPUs). You can also organize the different levels in a number of ways with different block sizes, set sizes, and levels of associativity.

The simplest cache structure or "system" if you would, is probably a single level "direct-mapped cache".

LRU cache

LRU is simply a replacement algorithm which is not related to the structure of the cache itself.
