What is the definition of a user in the context of a computer system?

In the context of a computer system, a user is defined as an individual logged into an account. This definition emphasizes the interaction between a person and the computer system, where the individual utilizes the system's resources, applications, and services. A user typically has personal settings and may have specific permissions or access rights based on their role or account type.

By focusing on the individual, this definition captures the essence of how people engage with technology, which is integral to understanding user-centric system design and security practices. Users can differ widely in their needs, levels of expertise, and the specific functions they perform within the system, but the commonality is that they are individuals or entities accessing the computer system through an account.

The other options describe aspects related to users or system roles but do not encapsulate the fundamental definition as effectively. For instance, managing hardware access refers to accounts or permissions rather than the user themselves, while a type of software application and a system-level administrative role pertain to other components of the system rather than the user as an individual.
