If you're reading this article, you're on a computer and on the Internet. But what exactly defines the words "computer" and "the Internet"? Many of us use these tools in our everyday life, but overlook the meaning of what they actually are and their intended purpose.
So, what exactly is a computer?
A "computer" doesn't always mean the large industrial machines that you see in movies, or the portable "laptop" computer that your parents use for work. Computers are just machines that take in data (as input), stores and processes the data, and displays data (as output).
We will be discussing the different ways computers input, store and process data, and output throughout the rest of the chapter.
And this "internet" thing you mentioned?
The Internet is the network of billions of different computers around the world. When you are going "online" (connecting to the Internet), you have the ability to almost instantaneously communicate with anyone in the world, access thousands of online databases, stream movies and more. The opportunities are endless.
Isn't that just the "Web"?
Many people confuse the "Internet" with the "Web", yet they are two very different tools. The "Web" is a collection of "websites" which are found on the Internet. Think about it like the ice cream section at a market. There are different flavors of ice cream in the ice cream section, which can be found in the market itself. Like the many different flavors of ice cream, there are a wide variety of websites on the Internet. There are websites to stream movies, websites to play video games, and educational websites like Mathisi-fy :). Once you find a website that you want to visit, you can access it through a web browser such as Google Chrome, Firefox or Mozilla. The browser pulls the website data from the Internet and displays it on your screen.
