What is the cache? 

Your web browser remembers each file that you open. This is called a cache. This means the browser doesn't have to newly retrieve files (including any images) from web sites each time you click Back or Forward. It's good practice to clear the cache to allow your browser to work better.

What are cookies?

A cookie is a file created by a web browser, at the request of a web site, that is then stored on a computer. These files typically store user-specific information such as selections in a form, shopping cart contents, or authentication data. Browsers will normally clear cookies that reach a certain age, but clearing them manually may solve problems with web sites or your browser.

What is browsing history?

A browser's history is a log of sites that you visit. When you use a browser's Back button, you are moving back one entry in the history log. Browsers will normally clear the history at regular intervals, but you may want to clear it manually for privacy.
