Thread: Cache

A cache (pronounced 'cash') is a temporary location where information is stored for very fast access. There are many types of caches in a computer, starting from the processor which has a cache known as the L2 cache. The operating system also has a cache known as the virtual memory or swap file where information in the RAM is temporarily swapped to the hard disk when the RAM gets full. Similarly the Web browser also has a cache for W~b pages that have been recently accessed.
