Ok, I know this sounds ridiculous to anybody under the age of 30. Everybody knows what a browser is, right? Nope. I know lots of people who use their computers almost every day who go completely quiet when I ask them what browser they're using. Internet Explorer? Silence. Firefox? Silence. Safari? Silence. Trying a different tack, "what program do you use to go onto the internet?" Dead silence. "How do you go to a web page, like CNN.com or Amazon?" The answer 9 times out of 10 is "Google".
So, here's the deal. If you're going to use a computer, and you're going to be asking other people for help, there are a few basic terms you need to be familiar with. Browser is one of those.
A browser is a program that you run that lets you access web pages on the internet. There are lots of them. The aforementioned IE, Firefox, and Safari, plus Opera, Google's fairly new Chrome, and others. They all do basically the same thing, they just have different layouts and features. Pick one and stick with it.
At the top of each of these browser program windows you will usually see two places where you can enter text. One is called the "address window" and the other is the "search window". Here's an illustration:
The arrow on the left points to the address window, the one on the right to the search window.
First, the address window. Say we're on the phone and you're complaining that you're on the American Airlines website trying to book a flight and you're having trouble. In fact, all you can see are ads for rental cars. The easiest way for me to make sure that you're on the right web page, and haven't accidentally navigated yourself out of AA entirely, is to have you read me the info in the address bar. So it's important for you to know where it is and what it looks like. Whenever you are browsing the web, the address (also called a URL) shows up in the address window.
And if you're trying to go to a website where you know the address (URL), then that's where you enter it. Quick tip here: you don't need to type in the "http://www" any more. If you do, you'll just be wasting time. All current browsers assume that that's what you want, so you can just type the last bit, like amazon.com or google.com. In fact, most of them don't even require the .com any more. You can just type amazon or google and you're good to go.
Second, the search window. In the illustration above the default search engine is Google, but there are other search engines available, and if you look closely at the left side of the little window you'll see a down-arrow. Clicking on that will show you a menu of other options, like Yahoo! and Wikipedia. You can always go to the home pages for Google.com or Yahoo.com, etc. by entering their addresses in the address window and entering your search terms there, but the search window is a handy little shortcut.
