Cache algorithms

In computing, cache algorithms (also frequently called cache replacement algorithms or cache replacement policies) are optimizing instructions, or algorithms, that a computer program or a hardware-maintained structure can utilize in order to manage a cache of information stored on the computer. Caching improves performance by keeping recent or often-used data items in memory locations that are faster or computationally cheaper to access than normal memory stores. Whe… WebJun 2, 2024 · Cache reduces the time taken to process a query, Cache minimizes the trip for requesting the same data. Cache decreases the load on the server.
