Step 1: Understand what HTTP is. HTTP stands for Hypertext Transfer Protocol, and it is used for transferring web pages on the internet.
Step 2: Know that computers communicate over the internet using ports. A port is like a door that allows data to enter or leave a computer.
Step 3: Learn that each type of internet communication has a default port number. This is the port number that is used if no other number is specified.
Step 4: Find out that the default port number for HTTP is 80. This means that when you access a website using HTTP, your computer uses port 80 by default.
