I hope I don't answer too late. Number 3 has already answered you, but I'm afraid you won't understand it, because it has to be explained from a distance. The Internet is literally a network of connected computers. Each of them has an address so that the others can communicate with him. These addresses are called IP addresses and represent four groups of numbers, each of which is from 0 to 255. However, it is much easier for people to remember and use words than numbers. Therefore, there is one thing on the Internet called Domain Name Server or DNS. Simply put, this is a list in which for each name of the type "some-your-site. Catfish" to have a corresponding IP address. That is, when you type in IE, Chrome, FF or any browser there, for example "Share. Net", DNS takes care to give information to which IP address to actually connect your device. Now comes the essence of this mythical www before the name of the address - it is actually an indication of the machine you are connecting to, which of its "folders" you want to enter -t. is what you are looking for - as you know www is the abbreviation that indicates that you want the "called" computer to send you the public website that is uploaded to it. Http is an indication of the protocol - or "language" that you will use when communicating with the computer in question. Or as an example - an address of the type http: \ ввв. my address. catfish is an instruction for your computer to do the following. 1. Connect to a computer whose IP address is equivalent to my address. catfish. 2. To tell the other computer that they will talk on the protocol http 3. That he wants to send him the things set for www - ie the site for the world wide web. So - this is a very simple model,
