cachevervanging
Cachevervanging is a fundamental concept in computer science, particularly within the realm of memory management and performance optimization. It refers to the process of deciding which data block to remove from a cache when new data needs to be brought in, and the cache is already full. Caches are small, fast memory areas designed to hold frequently accessed data, thereby reducing the latency of accessing slower main memory. When a cache miss occurs, meaning the requested data is not present in the cache, a new block of data must be loaded. If the cache has no available space, a replacement policy is invoked to select an existing block for eviction.
Various algorithms are employed for cache replacement, each with its own trade-offs in terms of complexity
