Day 9 – Forget gifts, it’s all about the cache

In computing, a cache (pronounced ‘cash’) is a ‘hardware or software component that stores data so that future requests for that data can be served faster’. In general, caching is used to speed websites up, however, sometimes a build-up of cached data can cause an online tool to run a bit slower.

Why do I need to know what caching is?

If an online tool integral to your teaching is suddenly running slowly, you may be advised to delete your cached data to see if this rectifies the issue. As a result, it can be really helpful to know what a cache is and how to clear it of data.

How do I clear cached data?
