There are four ingredients needed to access the Internet (1) an ISP, (2) a modem, (3) a Web browser and (4) an e-mail program. The Internet Service Provider (ISP) Your access to the Internet is through an Internet service provider (ISP), which can be a large company such as America Online or MSN, or any of hundreds of smaller ISPs throughout the country. You are offered unlimited access for a fixed rate per month. The Modem Depending on the kind of service you have, you will need a unit of hardware called a "modem" for connection. Slow-speed dial-up telephone access uses an analog modem, which may already be installed in your computer. If not, one can be plugged into the USB port. If you sign up for cable or DSL service, which is from 40 to 100 times faster than telephone dial-up, your provider may send you the appropriate modem, or you can purchase it at your local electronics store. Quite simply, opt for the high-speed service if you can. Dial-up modems are an exercise in extreme patience. Browsing the Web A Windows PC comes with the Internet Explorer Web browser. The Mac comes with Safari. Windows and Mac users quite often choose a different browser such as Firefox (www.mozilla.org) or Chrome (www.google.com/chrome), which offer additional features and are not as subject to attack by hackers. The first time you hook up to a new ISP, you may need their assistance to configure the dial-up or networking software in your computer. After that, all you do is launch the browser to "surf the Web." Sending E-Mail Although e-mail can be sent and received using your Web browser (see e-mail interfaces), your computer may come with a dedicated e-mail program like the ones found in smartphones. For example, the Mac comes with Mail, while Windows has renamed its free program many times: Outlook Express, Windows Mail, Windows Live Mail and Mail. However, many users prefer Eudora, Thunderbird and other e-mail clients. The first time you connect to a new ISP, you may need help in configuring your e-mail program to use their mail servers. From then on, you launch the mail program as you would any other application.
