If a user is registered on the site, then his device from which he is registered is not included in the local group?

Question

Computer networks

I'm rather delusional. But true or not:
1. Any hosting is a local area network.
2. Any user who registers on the hosting by default enters the local network and becomes its user.
3. The device from which the registered user enters the hosting also becomes by default inside the local network.
4. The main feature of the local network yavl. the presence of a Server Computer and a Client Computer.
I'm wondering which of the above is true?

Answer 1

1. any hosting is a network service
2. any user registering on a hosting simply leaves his data to this service. Not the fact that in this case he will have any additional access.
3. The device is not placed anywhere. It connects directly to the service provider.
4. The main feature of the network is the ability to send information from one device to another. A local network differs from a global one only in the number of devices on the network. The global Internet network works exactly the same as the local network, it's just bigger

Answer 2

1. Any hosting is... hosting :) In a very rough approximation - a powerful server equipped with web muzzles to keep users out of the shell, or with a bunch of virtual machines. Of course, he has a local network - the traffic somehow leaves, but the hosting user cannot get to it in any way - as a rule, he has a web-based hosting management face, sometimes ftp, sometimes ssh.
2. He does not enter anywhere, into any network. He logs in to the server, works on the server, does not get further than the server.
3. Fundamentally wrong. Nothing gets anywhere - this is not a VPN for you. The device becomes part of the "network" with the provider's server only when you purchase a VPN service (or when you connect to a corporate VPN).
4. The main features of the network are well listed by Saboteur
All of the above is false. In your head, excuse me, a complete mess, read the basic literature ...

Answer 3

What is the point of talking about what you do not put into practice?
In practice, a "local network" is only when all the routers are at hand and you can configure them, but in the case of an Internet connection, this is, to put it mildly, not so.
Everything else is not important, find out how it is customary to speak (textbooks, Wikipedia, etc., etc.) and say so.
