What is a memory read-hit?

A memory read-hit refers to a situation in which a requested data item is already present in the cache memory, resulting in a faster access time. When a processor needs to read data from memory, it first checks if the data is available in the cache. If the data is found in the cache, it is considered a memory read-hit, and the processor can retrieve the data directly from the cache without accessing the slower main memory. This helps to improve the overall performance and efficiency of the system.
