Meaning – The word cache refers to a special kind of buffer storage, that is usually faster than the main storage, and is tasked with holding instructions from one process that are required for the next process.
When we browse the internet, we usually login to certain websites with unique login credentials, and most of the times, we tend to save these credentials so that we don’t need tot repeatedly remember and enter the same, thereby reducing access time. These credentials are stored in the cache, and are found there as long as the cache is not cleared.
However, the cache gets populated over time, and its a good idea to clear it periodically. Now, clearing the cache removes all the saved data, so if you had login credentials in the cache, and you cleared it, those credentials will not be available for a future logins.
