What are the built-in users and users groups?

Answer 1

Built-in users and user groups are predefined accounts and collections of accounts in operating systems that facilitate access control and management. For example, in Windows, the built-in users include Administrator and Guest, while user groups like Users, Administrators, and Power Users help manage permissions for multiple accounts. In Linux, common built-in users include root and nobody, with groups like wheel and users serving similar purposes. These structures simplify user management and enhance security by organizing permissions based on roles.
