Final answer:
In a single-user workspace, access is generally limited to the individual who has access to the workspace's local file, maintaining a personalized and secure environment.
Step-by-step explanation:
When working in a single-user workspace, the access to this workspace is typically restricted to the user who has access to the workspace's local file only. This is because a single-user workspace is designed for use by one individual at a time, ensuring that the work environment is personalized and secure. In a single-user setup, an administrator may have the ability to access or assign the workspace, but this does not change the fact that the environment is intended for use by one user at any given time.
