Before you can visit a web site, you must be connected to the Internet.

19 Internet Service Providers
If you are at the Library, you may access the Internet through the Library’s WiFi service, or by using the Library’s computers.

20 Internet Service Providers
To access the Internet from home, you must use an Internet Service Provider (ISP).

21 Internet Service Providers
Internet Service Providers charge a fee for providing Internet access. Prices vary depending on the service package and the type of connection.

22 Internet Service Providers
The fee charged by the ISP for Internet access will vary depending on: Type of connection Speed of the connection Length of time (on the Web)

23 Internet Service Providers
The typical choices for home users are: Dial up access, using a telephone line. High speed access, using either Cable or telephone lines. Wireless access, using a cellphone service.

24 Internet Service Providers
Dial up access uses a telephone modem to convert signals to and from the computer. Most computers today have telephone modems built in.

25 Internet Service Providers
High speed Internet access through DSL (Digital Subscriber Line) or Cable require a special modem, usually supplied by the ISP.

26 Internet Service Providers
A dial up connection to the Internet requires the computer “dial” into the ISP’s network through the modem. The connection lasts only as long as the modem’s telephone connection is active.

27 Internet Service Providers
A high speed connection to the Internet typically maintains the connection as long as the cable or phone line is plugged into the modem. With this type of service, the Internet is “always on.”

28 Internet Service Providers
Internet service through an ISP usually includes: Multiple accounts Space to post personal web pages

29 Internet Service Providers
If you do not have, or want, Internet access at home, one option is to use computers at your local Library. Libraries do not provide accounts, however, or space for personal web pages.
