Login

Login is the act of registering a user on a local or global network so that the user can access files on the network, a single computer, or an online service.
By logging in you can also open a communication session.
This is usually done by entering a username and password.
With the client-server architecture, the client registers with the server. This means that the login can be carried out manually, i.e. by the user himself, or automatically, due to functions in the communication software or the modem.
