What is the internet?
The internet is really just billions of computers connected with wires that are run all over the earth. a connection of millions of computers all over the world. Through these connections, your computer has access to other computers all over the world called servers. These servers are the backbone of the web. They store websites and then serve them to your computer. When you typed techgenius.wordpress.com, you were actually accessing the web server that stores our website. The server is configured to allow anyone ‘view’ the website. However, to edit the website, you have to provide access codes i.e. a username and password. This is to prevent an authorized alterations and modifications to the site.
Food for Thought
There are almost as many webpages on the internet as there are neurons in your brain. (http://bit.ly/peoBvC, http://bit.ly/4rgHPg )

What is a Website?
In its simplest form, a website is a collection (folder) of files (usually web pages) stored on a web server and located at a web address like www.yahoo.com. So whenever you type www.yahoo.com you are actually requesting a file from Yahoo’s server.
So with that down, there are two kinds of websites.
- Static Websites
- Dynamic Websites
Static Website – A static website is simply a collection of HTML files. A webpage corresponds to a file. This means that a one page website with say a homepage only contains one file. A two page website would contain two files e.t.c. The web server will respond with the same webpage every time that page is requested. The main characteristic of a static website is the fact that the website will not change irrespective of the time, day, location or computer that is accessing it. It will look the same to anyone and everyone. It remains the same unless altered by the Web Designer hence the name ‘Static’.
Dynamic Website – A Dynamic website is a collection of files containing instructions for generating WebPages. Unlike static websites, when a page is requested, the server performs the instructions stored in the dynamic webpage and the respond based to the instructions on the page. This means that if the instruction say “Print Today’s Date”, the web server will respond with today’s date. And if you were to request the same page tomorrow, it would not respond with today’s date, rather it will respond with tomorrow’s date. And thus the main characteristic of Dynamic website is the ability to automatically change depending on what instructions web given by the Web Developer
What is HTML?
HTML stands for HyperText Markup Language. It is used to identify the elements in a websites like a picture, link, heading, sub-heading, paragraph and so on. But if HTML is used to “identify” elements in a webpage, that means all websites out to look the same right? So how come web sites all look different. That is where another language comes in called CSS
What is CSS?
CSS stands for Cascading Style Sheets. CSS handles to alter the appearance of web pages. It is very important because it tells the browser how to display the elements. Its responsible for the aesthetics of the page like colour, font, background image, margins and so on. CSS works with HTML to display rich looking websites.
So in conclusion,
- The internet is simply a connection of billions of computers all over the world.
- A Web site is a folder stored on a web server that can be accessed by a web address e.g. www.google.com
- A Static website is a collection of web pages written in HTML that always looks the same unless altered by the Web Designer
- A Dynamic website is a collection of files that contain instructions for generating WebPages.
- HTML and CSS are used to generate the content and appearance of a webpage respectively.
