Browser caches are an instance of the optimization mechanism known as a cache.

The browser cache is nothing more than a place on your hard disk where the browser keeps things that it downloaded in case they're needed again.

For example, the first time you visit a web page, the browser will download some files like the logo image or icon images, so that it can be shown.

Since it's faster to get something to display from your hard disk than it is to get it from the internet, every time thereafter when you visit the same web page or any page on that domain, the browser will be searching for the required images and other files on its cache folder. Only if not found it goes to the internet to download them.
