What is a memory cache-write-hit-write-back?

A memory cache-write-hit-write-back is a caching technique used in computer systems. It refers to a situation where a write operation is performed on a memory location that is already present in the cache and has been modified. In this case, the modified data is written back to the cache instead of directly updating the main memory. This helps in reducing the number of memory accesses and improving overall system performance.
