In computing, a cache is a hardware or software component that stores data so that future requests for that data can be served faster, the data stored in a cache might be the result of an earlier computation or a copy of data stored elsewhere. Here we want to look at how one can clear cache from his or her devices.
What is Cache Or Cache Data?
A cache hit occurs when the requested data can be found in a cache, while a cache miss occurs when it cannot. Cache hits are served by reading data from the cache, which is faster than re-computing a result or reading from a slower data store. Thus, the more requests that can be served from the cache, the faster the system perform.
With a host of technological advancements wrapped around our lives, we have somehow, come to accept technical jargons without quite understanding what they really mean. Have you ever wondered what is cached data? Then you may not be the only person not aware of what it means.
Our phones have become so much more than a mode of making and receiving calls. After all, that is what phones were supposed to do when they were created.
But now they are meant to help us juggle lives, notify us of communications through different apps and lastly, make and receive calls. All devices that connect to the internet use cached data in one form or another.
Why Do We Need to Clear Cache Data or Cookies?
Many times web developers have to make updates to the files that comprise your site in order to push a change or new feature live. If we change a file that your browser has cached, it is going to keep serving the old, cached version of the file and you won’t see our most recent changes.
This is when you may encounter browser errors like run time error, buttons missing on the page, unable to save the Timesheet, Timesheet doesn’t allow you to enter time, the action performed doesn’t respond appropriately etc.
It is a good idea to clear your browser cache because it performs the following functions:
====> It prevents you from using old forms
====> It protects your personal information
====> It helps our applications run better on your computer and your mobile devices.
When you visit a website, your browser stores:
====> Information (such as the location of the site you visited)
====> Files used to run an online application
====> Downloads (such as old versions of forms)
When we update our application, your browser may still use old files. If you don’t clear your cache, you may see old forms. Old files can cause display or access problems when you apply online.
Why Cached Data Exists?
The main reason why cached data exists is to make loading time faster. So if the device already has the layout of the website saved in the form of cached data, it will not have to load that same data once again. This helps in quickening the process of loading the website.
While cached data is helpful for computers, smartphones, and tablets, it can take up space on your device and it may, over a period of time, get corrupt. While the cached data on your device can be helpful for the websites you visit regularly, it can be considered a waste for those websites which you will be visiting just once.
Is It Safe to Delete Cache Files
It is generally safe, though a little dangerous depending, to do it but often not worth the effort. The caches in /System/Library/Caches are generally small and useful, the ones in /Library/Caches are fewer system caches and much more readily cleared.
If you have a look in /Library/Caches you will find a bunch of applications have a cache in there, none of them particularly large though dropbox sometimes has a fair-sized cache. This folder can run quite large just because so many apps cache something in there.
If the cache /Library/Caches folder is over 3Gb then you have something that is caching quite a lot. On the three machines, I just checked none had a /Library/Caches folder over .75 Gb so I’d go right ahead and remove some of it.
Don’t worry about age, I’d worry about the size. In the terminal run du -s /Library/Caches/* | sort -n and you will get a good idea of which are the larger caches. Doing it with the System fully up can be a little dangerous. If you do it then, reboot immediately afterwards.
