At school we were given the task to find and read what exactly is www and http and what is the difference between the two. I found information on the internet, but it is written in a very high style and it is very incomprehensible to me. I read, I thought, but I understood almost nothing. So I want someone who is more aware to explain to me in a language I understand what www (World Wide Web) and http are and what exactly is the difference between the two. I can learn all the terminology on the net, and the information by heart, but I want to understand it in reality, and I have a couple before that that I want to correct and this is an opportunity. If I tell you about these two and discuss with the IT teacher, she will see that I understand the subject and will write me a good grade, so please help!

Hello, it is best to write in a specialized forum, for example in kaldata.com - there you will get a lot of answers and you will be able to compose yours more easily.
HTTP is a hypetext transfer protocol. www is actually under a domain, an identifier that indicates that it is a website. Both are in many cases used interchangeably, except when there are other services besides a website. For example http-web, ftp-file transfer protocol-for uploading files, again through the browser, but it looks and works in a completely different way. And also www. domain. tld for web mail. domain. tld for mail To summarize, one is a protocol, the other is a domain (DNS) record for a website.
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,
