A webpage is basically a text file formatted a certain way so that your browser (ie. Chrome, Firefox, Safari, etc) can understand it; this format is called HyperText Markup Language (HTML).

These files are located in computers that provide the service of storing said files and wait for someone to need them to deliver them. They are called servers because they serve the content that they hold to whoever needs it.

In order to deliver the web contents to the requester, those servers need to have address so that the person needing said content can make a request.

These addresses are called IP (Internet Protocol) Address, a set of 4 numbers that range from 0 to 255 (one byte) separated by periods (ie. 127.0.0.1).

Another concept that is important to know is that the courier service traffic for the delivery can be one of two: Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). Each one determines the way the content of a server is served, or delivered.

TCP makes sure that all the content that is needed gets delivered. It accomplishes this by sending the file in small packets of data and along with each packet a confirmation to know that the packet was delivered. The downside to TCP is that because it has to confirm whether you got the packet or not before sending the next, it tends to be slower.

UDP, on the other hand, is usually used to serve live videos or online games. This is because UDP is a lot faster than TCP since UDP does not check if the information was received or not; it is not important. The only thing UDP cares about is sending the information. That is the reason why if you've ever watched a live video and if either your internet connection or the host's drops, you would just stop seeing the content; and when the connection comes back up you will only see the current stream of the broadcast and what was missed is forever lost.

HTML is short for HyperText Markup Language and is the language of the World Wide Web. It is the standard text formatting language used for creating and displaying pages on the Web. HTML documents are made up of two things: the content and the tags that format it for proper display on pages.

Content is placed in between HTML tags in order to properly format it. It makes use of the less than symbol (<) and the greater than symbol (>). A slash symbol is also used as a closing tag. For example:
