What is the Web ?

The World Wide Web—usually called the Web for short—is a collection of different websites you can access through the Internet. A website is made up of related text, images, and other resources. Websites can resemble other forms of media—like newspaper articles or television programs—or they can be interactive in a way that’s unique to computers.

The purpose of a website can be almost anything: a news website, an advertisement, an online library, a platform for sharing images or videos.

What is URLs and the address bar ?

Each website has a unique address, called a URL (short for Uniform Resource Locator). It’s like a street address that tells your browser where to go on the Internet. When you type a URL into the browser’s address bar and press Enter on your keyboard, the browser will load the page associated with that URL.

In the example below, we’ve typed into the address bar.

What are Social networking websites ?

Social networking websites are another way to connect and share with your family and friends online. Rather than sharing with just a few people over email, social networks make it easier to connect and share with many people at the same time. Facebook is the world’s largest social networking site, with more than 1 billion users worldwide.

What are Chat and instant messaging applications ?

Chat and instant messaging (IM) are short messages sent and read in real time, allowing you to converse more quickly and easily than email. These are generally used when both (or all) people are online, so your message can be read immediately. By comparison, emails won’t be seen until recipients check their inboxes.

Examples of instant messaging applications include Yahoo Messenger and Google Hangouts. Sites like Gmail and Facebook, even allow you to chat within your web browser.
