What is Cache?
Cache is an accumulation of data or information temporarily stored in a computer system so that subsequent requests for that data can be processed more quickly than if the data had to be retrieved from another source It can be stored in RAM (random access memory), on a hard drive, or on a solid-state drive. Cache is an important component of computer systems and networks because it can improve system performance by reducing the chances of network slowdowns and data latency.
Cache can be divided into two main categories: hardware cache and software cache. Hardware cache is a physical cache stored on a computer’s processor or hard disk drive. When a computer’s processor requests data from a hard disk drive, the hardware cache acts as an intermediary between the two, allowing the data to be sent to the processor more quickly than if it was requested directly from the hard disk drive. Conversely, software cache is a type of cache stored in RAM (random access memory) and is used to improve the performance of frequently-used programs or processes.
When cache is used correctly, it can significantly improve the performance of a system. However, it can also cause problems if not managed correctly. For instance, if too much data is stored in cache, the system may become slow due to bottlenecking and decreased memory availability. Additionally, if the data stored in the cache is not purged or refreshed regularly, the data may become stale or obsolete, further slowing down the system.
