When learning to become a web designer, it is critical to understand how networking works since so many different parts come together to make a web site work.
When a web site goes down, it can be anyone of the different parts that has failed. Being able to pinpoint that part, and who is responsible for it is key to getting the web site back up and running again quickly.
Internet and WWW aren’t the same thing
First of all, let’s get one thing straight. The internet and the World Wide Web are not the same thing.
The internet is a series of interconnected networks. It is a network of networks built of of private, public, academic, business, and government networks.
The internet, and the World Wide Web are based on plain text.
Everything on the web is plain text: .html, .css and .js files. (Pictures, audio and video aren’t in plain text of course – but they were added on the web much later.) To be a productive web designer, you need to be able to efficiently edit text files – and even several ones at once.
For years, and even decades, computer networks were criss-crossed by typing commands in Terminals and using text-only tools like FTP for transferring files or various text editors (from nano to Vim and Emacs) to create and edit them.
