The Web at a Glance: What Is the Web?

The World Wide Web is a collection of electronic files linked together like a spider web.

These files are stored on computers called web servers located around the world.

The Web has evolved into a global electronic publishing medium.

The Web has enabled an explosion of electronic commerce.

The Web at a Glance: What Is the Web Made Of?

The Web consists of:

Your personal computer or mobile device

Web browser software to access the Web

A connection to an Internet service provider (ISP)

Servers that host the electronic files

Routers and switches to direct the flow of data

The Web at a Glance: How the Web Works

Web pages are stored on web servers located around the globe.

Entering the Uniform Resource Locator or URL of a web page in your web browser or clicking a link sends a request to the server that hosts the content.

The server transmits the web page data to your computer and your web browser assembles it on your screen.

The Web at a Glance: Web Pages

A web page is an electronic

document written in a computer

language called HTML (Hypertext

Markup Language).

Web pages can contain text, graphics,

audio, video, and animation, as well as

interactive features, such as data entry

forms and games.

Each page has a unique address known as a URL (Uniform Resource Locator), which identifies its location on the network.

Web pages usually contain hyperlinks to other web pages or resources. Hyperlinks are text and images that reference the addresses of other web pages

The Web at a Glance: Websites

A website consists of one or more web pages that relate to a common theme, such as a person, business, organization, or a subject, such as news or sports.

The first page is called the home page, which acts like an index, indicating the content on the site.

From the home page, you can click links to access other pages on the site or other resources on the Web

The Web at a Glance: Navigating the Web

There are three main ways to move between web pages or websites:

Clicking a text link

Clicking a hyperlinked graphic, such as a button, photograph, or image

Typing the URL of a web page in the location box (also known as the address field) of your web browser and then pressing the Enter or Return key

The Web at a Glance: How Hyperlinks Work

A text or graphic hyperlink hides a URL.

Clicking a hyperlink passes the URL to your browser.

Clicking different parts of a linked graphic, called an image map, takes you to different web pages or different places on the same page.

In addition to pointing to web pages, hyperlinks can access media files, such as audio or video clips.

The Web at a Glance: Web Addresses

A URL indicates where the web page is stored on the Internet.

URLs almost never useback slashes (\). All slashes are forward slashes (/).

You need to type a URL exactly for your browser to locate the desired web page, otherwise you will access the wrong site or get an error message.

Although URLs may contain spaces between characters, they usually do not.

The location box or address field on your browser indicates the URL of the page you arrived at after clicking a link.
