Definition: "Cache" is a specialized form of computer memory. In the case of Internet, "cache" is commonly used in the context of "browser cache". Cache is designed to speed up the computer by prioritizing its contents for quick access.
How it works: cache holds copies of recently accessed data such as a web page and pictures on web pages. It keeps this data ready to "swap" onto your screen within fractions of a second. So, instead of requiring your computer to go to the original web page and photos in Denmark, the cache simply offers you the lastest copy from your own hard drive.
This caching-and-swapping speeds up page wieving because the next time you request that page, it is accessed from the cache on your computer instead of from the distant Web server.
Note: the browser cache should be emptied periodically.
