Final answer:
Restricting user access to programs and data files in an online computer system involves user identification, user authentication, and determining user access rights. Wearing identification badges is not directly related to this.
Step-by-step explanation:
In an online computer system, restricting user access to programs and data files involves several measures, such as user identification, user authentication, and determining user access rights.
User identification involves assigning unique usernames or IDs to individual users. This helps in tracking and managing user activities on the system.
User authentication is the process of verifying the identity of users. This can be done through various methods, such as passwords, biometrics, or two-factor authentication.
Determining user access rights involves assigning specific permissions or privileges to users. This ensures that they only have access to the programs and data files that they need for their role or level of authorization.
Wearing identification badges, on the other hand, is not directly related to restricting user access in an online computer system. It is a physical security measure commonly used in physical locations to identify authorized personnel.
