2. I'm not sure what type of browser I use. How can I find out?

Most people have Netscape, Internet Explorer, or AOL as their browser software.  If you are not sure which browser is on your computer, you can usually find out by clicking on the Help button at the top of your screen and selecting the last menu option (use the arrow keys to scroll down). This should provide information about your browser, including the version number. Software developers release new versions when they add new features or make changes. The higher the version number, the more recent the software you have on your computer.
