Home: this is the page that the web browser automatically displays at start up. Most web browsers let
the user choose the home page.
Forward: this button lets the user move forward to web other web pages. Here forward indicates the sequence
pages have been visited in. In other words, if the user uses the back button to visit a web page that had already
been visted, the forward button would let the user move back to the most current page.
Back: this button lets the user move backward to web pages already visited.
Reload: this button lets the user see the most current version of a page visited. The reason why this
button is important is because most web browsers load some pages from cache (a portion of memory set aside by the
browser to save recently visited pages), and the Reload button forces the browser to visit the server where
the web page is stored to download the most recent version.
