can include text, images, videos, and other types of media files.
Websites are locations connected to the Internet that maintain one or more web pages. A website is a set of related web pages typically served from a single web domain and hosted on at least one server that is accessible via the Internet. All publicly accessible websites collectively constitute the World Wide Web.
A web page is a document, typically written in text, that can incorporate multimedia content like pictures, audio, and video that is suitable for the World Wide Web and web browsers.
A web browser is the application that you use to display a web page on a computer or mobile device. It coordinates the various resources and elements that are found on each web page so that they are displayed correctly in a form that is humanly readable. The major web browsers are Internet Explorer, Google Chrome, Mozilla Firefox, Opera, and Safari. The first web browser was invented in 1990, and it was called WorldWideWeb, to suggest that is was the only software needed to navigate websites and web pages found on the real World Wide Web.
Getting back to the Internet, the most common use for the Internet is to browse the World Wide Web using web browsers. However, since the Internet is a global network of interconnected networks, the Internet is capable of doing much more than providing access to websites. With the help of the Internet, we can send email messages to other people, use programs that take real-time data from the Internet and share it with us (for example, traffic data, weather data, stock market data, and so on), transfer files to other people across the globe, chat with others, access other computers across the globe, and much more. The ways the Internet can be used are practically unlimited, whereas the WWW is just one way to use the Internet.
Understanding the World Wide Web
Every website and web page on the World Wide Web has an address that can be used to find it with the help of a web browser. That address is called its URL (Uniform Resource Locator), and it consists of the following elements:
Protocol The specific data-transmission rules for accessing the resource on the Web. For websites and web pages, it can be http:// (Hypertext Transfer Protocol) or https:// (the s at the end stands for Secure). It used to be that you had to type the protocol to reach a website, but today’s web browsers supply it automatically.
Prefix www is the prefix used for visiting websites on the Web. Most websites do not require it, and they can be accessed without typing www as the prefix. For example, typing www.example.com or example.com leads you to the same web page. The www prefix must always be followed by a dot.
Domain Name This consists of one or more parts or labels, delimited by dots, like example.com. The right label (com) is called the top-level domain. Each label to the left of the top-level domain is a subdomain of the domain on its right. In example.com, example is a subdomain of the com domain. Some websites may have multiple subdomains, like example1.example2.com. In this scenario, example 1 is a subdomain of example 2, and example2 is a subdomain of the com top-level domain.
