“Cache” is a familiar component that boosts web load speed and facilitates web movements. At times, users are suggested to clear the cache regularly. There are two types of clearing cache: clean and flush.
Yet, is it necessary to clear the cache? And what are the differences between the terms clean cache and flush cache?
What is cache?
In computing, “cache” is a high-speed data storage layer that temporarily retains data. With cache, if users request stored data in the future, the websites will serve up faster by accessing the data in storage.
Since cache allows people to reuse data, it will help reduce the amount of time to access new data, as a result, it will boost web loading speed and make it more convenient for web visitors
Why should users clear caches?
Since temporary data will be stored in caches, clearing cache will help users save storage space and remove unnecessary items. In addition, if your device needs to be reset, clearing cache is what you have to do.
How cache flushing differs from cache cleaning?
In general, when users clean the cache, only items from the enabled cache are removed. In other words, when cache cleaning, users will not affect other data or applications since they only decide to clear the cache.
Meanwhile, when users flush the cache, that means the whole type of cache will be removed resulting that other data, as well as applications stored in that cache, will all disappear.
