1) Using strong passwords
2) Implementing user authentication
3) Setting file permissions
4) Encrypting data

Answer 1

Restricting user access in an online computer system involves using strong passwords, implementing user authentication, setting file permissions, and encrypting data.

Step-by-step explanation:

In an online computer system, restricting user access to programs and data files includes:

1. Using strong passwords: This involves creating passwords that are difficult for others to guess, containing a combination of letters, numbers, and special characters.
2. Implementing user authentication: This ensures that only authorized users can access the system by requiring them to provide valid credentials, such as a username and password.
3. Setting file permissions: This involves assigning specific access rights to files and folders, allowing only authorized users to read, write, or execute them.
4. Encrypting data: This process converts readable data into an unreadable format using encryption algorithms, making it difficult for unauthorized users to access or interpret the information.
