Coding School Lesson 1: What is the World Wide Web?
Coding School Lesson 1 Objectives
Welcome to Lesson #1 of Coding School! Because the type of computer coding we will attempt to learn is web based, I thought it would be a good idea to start off with a firm foundation of what the web is.
Your objectives for this week are as follows:
- Know the difference between the World Wide Web and the Internet (No, they are not the same)
- Gain a working knowledge of how the Internet and the World Wide Web are connected
- Gain a basic understanding of how the Internet works
Ready? Let's do this, ya'll!
The World Wide Web vs The Internet
Although most people use the terms "the web" and "the Internet" interchangeably, they are actually two very different things.
The Internet came before the World Wide Web, or the web for short, and since the emergence of the web, our lives have never been the same.
If we are to become competent coders, we need to make certain we have a full understanding of the technology that makes websites, web apps and mobile apps come to life.
What is the Internet?
The Internet is a system of interconnected computer networks that all make use of the same rules. These rules are officially known as protocols, and these protocols spell out how computers talk to one another on the network.
The basis for the Internet was developed the United States Government in the 1960s. The government got together with a few private companies to develop a method to communicate huge amounts of data via computers. At the time, it was known as ARPANET.
ARPANET is the network that became the technical basis for the modern Internet. It was developed under the directon of the U.S. Advanced Research Projects Agency (ARPA). President Dwight D. Eisenhower created ARPA for the purpose of expanding technology and science.
Today's Internet is a global collection of physical cables which can include copper telephone wires, TV cables, and fiber optic cables. Even wireless connections like Wi-Fi and 3G/4G rely on these physical cables to access the Internet.
In the begining, the Internet was mostly used by the government and universities to exchange news, email, and files or to log into computers from remote locations.
The Internet is basically the mother-ship of all networks, it includes all public and private computer networks, including our personal home networks and the internal networks we use at work.
The Internet network is what allows our communication services to work, and we all use it, probably every day. FTP is a protocol that allows us to move files, instant messaging allows us to Facebook chat our friends, most postal mail has been replaced with electronic mail (email), we use VoIP to talk on the phone, and we backup all of our data to the cloud.
How the Internet Works
What is the World Wide Web?
The World Wide Web (the web) is a vast collection of websites you can access through the Internet. The web is what most people falsely believe to be the Internet.
The World Wide Web is nothing more than an information sharing application that runs on top of the Internet. In truth, the web is only one of many applications created to run over the Internet.
Once you connect to the Internet via some type of Internet Service Provider (ISP), you can access and view websites using a type of software application called a web browser.
Common web browsers include Google Chrome, Mozilla Firefox, and Apple Safari. Internet Explorer or IE is another popular web browser, but true friends don't let friends use IE (it's commonly known by tech savvy people the world over, that IE is terrible, but, I digress...).
Anyhow, web browsers display websites that are stored on the Internet, and this ginormous collection of webpages make up the World Wide Web.
The Web as I envisaged it, we have not seen it yet. The future is still so much bigger than the past— Tim Berners-Lee, inventor of the World Wide Web
Interlinking The World Wide Web to Coding
You learned above the World Wide Web is a collection of different websites you can access through the Internet.
A website is made up of related text, images, videos and other resources. The purpose of a website can be almost anything: a news platform, an advertisement, an online library, a forum for sharing images, or an informational like the one you're on now.
These webpages are created using computer code, and at the very heart of all web pages and websites, is HTML.
Did you already know the web is different from the Internet?
Lesson Wrap Up
In this lesson, you learned there is a difference between the Internet and the World Wide Web, you learned the history of the Internet, and you learned some basic technical specifics of how the Internet works.
Congratulations! You are already leaps and bounds ahead of the average person.
The objective of this coding school project is to teach ourselves to code, so we can create websites, web applications (apps) or mobile apps that will be displayed on the World Wide Web.
Having rudimentary technical understanding of how the World Wide Web and the Internet works will come in handy later on when you learn how to get your creations online for the whole world to see.
