What is the purpose of logging in to a network?

Logging in to a network primarily serves the purpose of authenticating the user. This process involves verifying the identity of the individual or device attempting to gain access. By requiring a username and password, networks can ensure that only authorized users can enter or interact with their systems. This is crucial for maintaining security and protecting sensitive information from unauthorized access.

When a user logs in successfully, they are granted permission to access files, applications, and resources that are set for their specific privileges, which helps protect the integrity of the network’s information. Authentication establishes a crucial boundary that ensures users can only perform actions they are permitted to do, thus maintaining the security and functionality of the entire network.
