The video tutorial explains the concepts of cache hit and cache miss, highlighting their differences and impacts on system performance. A cache hit occurs when requested data is found in the cache, improving system efficiency by reducing access to slower storage. Conversely, a cache miss requires data retrieval from slower storage, negatively affecting performance. The cache hit rate measures how often the cache fulfills requests from its store, with a high rate indicating effective data storage. A low rate suggests insufficient cache size or infrequent data access.
