Cache Tutorial

What Is Cache?

Cache is temporary storage your computer uses to speed things up.

It saves bits of data, like images, scripts, or settings, so websites and apps load faster the next time you use them.

Over time, cache can get cluttered or outdated, which may slow down your system or cause glitches.

That’s when purging it helps!
