Which of the following provides full access to a computer?

• A. Gives guest access only
• B. Provides full access to a computer
• C. Provides read-only access
• D. Restricts access to some files

Answer: (B)

Access control determines what actions a user can perform on a computer. Full access means having all permissions: you can read, write, execute, install software, change settings, and access most or all files on the system. This level is usually given to administrators who maintain and configure the computer. The other options describe restricted or partial permissions: guest access is limited, read-only access allows viewing but not changing, and restricting access to some files leaves many areas inaccessible. So the option that provides full access is the one that grants all privileges to the system.
