  4. Why Do You Need a Modem?

  5. The biggest difference between modems is speed which is called the baud (bod) rate. The rate refers to how many bits (digital pieces of info) per second can the modem send and receive. • Ex: 56K or 56,000 bps (the most typical dial-up modem speed) • Broadband (high-speed) connections refer to: • Satellite or cable • T1 Lines • DSL or ISDN • Other variations of the connections mentioned above Modem Speeds

  6. A collection of related pages is called a web site. • Each website has a home page (similar to a table of contents). It’s usually the 1st page of the site. • A site can also have an entry page (splash page), • which will lead you to the home page. The World Wide Web
