Direct Mapped Cache

A direct-mapped cache is a straightforward type of computer memory system that helps speed up data access. It divides the cache into slots, each designated for a specific main memory location, based on its address. When the system needs data, it quickly checks the assigned slot. If the data is there, it's a hit; if not, it replaces whatever was there with new data. This method is simple and fast, but can lead to frequent overwriting if multiple addresses map to the same slot, which may slow performance in some scenarios.
