It wasn't until the early 'nineties that a research team at the National Centre for Supercomputer Applications (NCSA) in the US developed the mother of all modern browsers. It's name was Mosaic, & it's still around today.
One member of that team was Marc Andreessen, who went on to form Netscape, the company that developed Navigator. After initially pooh-poohing the idea of the Internet, Microsoft realised that the Net was worth looking at & developed its own browser, Internet Explorer. The rest, as they say, is history.
Both IE & Navigator have navigation buttons on their toolbars that improve your journey by letting you take shortcuts. Once you have started browsing, the Back button lets you go back, one at a time, to any of the previous stops you've made.
Similarly, the Forward button will return you, one stop at a time, to the farthest stop you'd reached before deciding to return to a previously visited site.. The Stop button is like the emergency brake, & stops a site from loading . You can use this button if you've clicked on the wrong link, or clicked before finding out whether the information you were after was there or not. The Reload or Refresh button lets you restart if you've stalled, or update a page if it's changed since your arrival.
Finally, The Home button will take you to the page set up in your browser as the first one you're taken to when your browser is launched. This is also known as your start page. In all cases, the default setting will be the home page of either the browser developer or your Internet Service Provider (ISP), if you want a different page to start from - perhaps a favourite site or a search engine - do the following, depending on which browser you're using. For IE , select View / Internet Options / General & fill in the URL of the site you want to start from in the Address field. For Netscape Navigator, select Edit / Preferences / Navigator & fill in the URL in the Location field.
