Is Unix a multi-user operating system?

Answer 1

When a user logs in to a Unix system, the current working directory normally starts at the directory/file

Answer 2

UNIX systems are absolutely multi user. You can have as many sessions as you want/need with the same user or with different users - as long as you have access to them, obviously.

That if the administrator does not restrict the access. This is mostly valid for CLI (command line interface).

When using GUI, although it's still multi-user in definition, for obvious reasons only 1 person can be logged at a time in one specific machine, which does not prevent you from being able to access via command line or GUI from another terminal (if allowed).

Also, once you're logged in with one user, you are still able to switch to another user without the need of a logoff (while using CLI) and the function somehow recently adopted by Microsoft which allows you to run commands as an specific user (such as admin)
