Multiple user accounts on one laptop?

There are PCs at school. You enter your individual user name and password on these PCs. Can you do this on normal laptops?

Yes, with a lot of effort.

Yes you can.

At least Windows and Linux support that.

Well, that's not that much effort.

And how exactly?

Ah

Very easy with Windows. Why is there the menu item: User accounts?

Clear. In Windows 10: You go to the settings menu on your PC, go to Accounts and then to "Family and other users". There you can create several users with different properties, assign passwords etc.

You can do that, but then everyone can still access any hard drive. Like in school, you would need a server and a management system like Windows Server. That already costs 5000 euro in software

Ah, thanks. 😊

As I described it in my answer.

If you have no idea…

I just wanted to inquire. I'm a MacBook user

You don't have to dimension it so high if you only need it for at home.
The most expensive one will be the Windows server license. You can also run the OS on an Intel NUC, and the "management" system is called Active Directory.

Then everyone can still access any hard drive

Well. A simple rights management can be set up quickly. By default, other users of the same system can't access your data if they do not have administrative rights.

Even if you shouldn't give any more answers. The whole thing has not yet been technically clarified!

On the MacBook, you can add more users in the settings.

But that's not like at school!

The school has its own authorization and authentication server and a remote management system.
Mostly so many for login to the WLAN with your own devices and registration via Windows.

Short explanation:

Because at school every student can register on any pc. Every time you log in, your account is "loaded" from a server.

Loaded is not quite right. But enough for the explanation.

And then not every account has to be on all PCs!

Ah. If you have something to add, it's ok. All have just repeated themselves here.
And thanks for the answer…
