Connecting to the Internet • In order to connect to the Internet you must have: • A modem: allows your computer to send and receive signals though telephone lines • An Internet service provider (ISP): required for all home connections • Browser software: might need plug-in programs to retrieve some types of media applications
Navigating the Web • In order to work with multimedia on the Internet, you must understand: • The browser screen and its standard elements • URL addresses and the information they contain

Searching the Web • Use search engines to find the right Web page: • Create search queries that include keywords. • Use Boolean search strategies to narrow your search. • Use the right search engine to conduct faster, more efficient searches.
