User Account
A user account is an identity for a user on a computer or network that includes a username and password, allowing for personalized settings, file storage, and access control. It authenticates a person and grants them specific permissions to use a system, and it separates individual data and preferences from other users.
Key features and purposes
Identification: A username and password combination is used to uniquely identify a user to the system.
Security: User accounts protect individual files and settings from unauthorized access by other users on the same computer or network.
Authorization: The account's permissions determine what resources and settings the user can access and modify.
Customization: Each account stores a user's personal files, preferences, and settings separately, creating a unique environment for that person.
Types of accounts:
Standard user: Has limited permissions and cannot perform certain system-level tasks, such as installing applications.
Administrator: Has full access to the system, including the ability to change settings, manage other accounts, and install software.
Service account: An account for programs or services to run under, rather than for an individual user.
