The Internet

The World Wide Web is the part of the Internet which presents electronic information in an interactive format.

The World Wide Web

The World Wide Web is made up of web sites. Each web site has one or more web pages.

Anyone can have a web site:

The World Wide Web

Web pages contain special areas called hyperlinks. These links can appear as underlined words. Pictures or images on the page can also be hyperlinks.

The World Wide Web

Clicking on a hyperlink will take you to another web page.

Everything on the World Wide Web has a unique location. You can go directly to a web page by typing in its exact web address. Web addresses look like this:

Web Browsers

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

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.

Internet Service Providers

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

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.

Internet Service Providers

The fee charged by the ISP for Internet access will vary depending on:

Internet Service Providers

•Type of connection

•Speed of the connection

•Length of time (on the Web)

The typical choices for home users are:

Internet Service Providers

Dial up access, using a telephone line.

High speed access, using either Cable or telephone lines.

Wireless access, using a cellphone service.

Dial up access uses a telephone modem to convert signals to and from the computer.

Most computers today have telephone modems built in.

Internet Service Providers

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

Internet Service Providers

The connection lasts only as long as the modem’s telephone connection is active.

A dial up connection to the Internet requires the computer “dial” into the ISP’s network through the modem.

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.”

Internet Service Providers

Internet service through an ISP usually includes:

Multiple e-mail accounts

Space to post personal web pages

Internet Service Providers

If you do not have, or want, Internet access at home, one option is to use computers at your local Library.

Internet Service Providers

Libraries do not provide email accounts, however, or space for personal web pages.
