In the ever-changing world of high-tech gadgets and gizmos, a whole load of jargon is thrown our way that many of us don’t necessarily understand. In this article we are tackling the tech terminology around “cached data”, and explaining just what is cached data memory.
WHAT IS CACHED DATA?
Cached data is information stored in memory which comes from a website or an app that is stored on your computer, smartphone and tablet. This data is stored on your machine so that the next time you go to use it, it will already be available.
WHY DOES CACHED DATA DO THIS?
The simple reason is to save on loading time. A website, for example, might save data about the website’s layout on your PC. By doing this, it means your computer won’t have to load it from the internet all over again next time – it’ll already be there on the machine, which is much quicker.
DOES CACHED DATA TAKE UP SPACE?
Yes, the downside to cached data is that it is taking up memory space on your device, which means you should probably clear it every now and again. Cached data is useful for websites you visit regularly, but it’s a waste of space for websites you visit once.
WILL CLEARING CACHED DATA CAUSE PROBLEMS?
This is hard to say. In general, clearing the cache in an app or multiple apps should not be a problem, as apps usually has their own mechanisms to regenerate the data and store it in the cache. However, cleaning all the server cache for a huge multi-user application client-server app will lead to a lot of computation to regenerate that data. In some cases, this might be a problem and slow the app performance drastically.
So, a simple rule:
- If you are talking about your own PC or mobile device – got for it, it should
not be a problem.
- If it is a big app – do not do that unless you’re really know what you are doing and why you need to do that.

In a vеrу unique way, cached data helps thе іntеrnеt wоrld gо round a lіttlе ѕmооthеr, by hеlріng wеbѕіtе pages load fаѕtеr fоr people vіѕіtіng wеb раgеѕ frеԛuеntlу аnd аlѕо can rеduсе CPU usage аt thе ѕаmе tіmе. Hopefully this article helps you answer the question of just “What is Cached Data”.
