User Account

index img

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.
