Physical access control are systems that physically prevent you from gaining access to the computer or other resource. For example, the lock on the outside door of a computer room is one simple type of physical access control system - it prevents you from gaining access to the computer unless you are authorized. A logical access control system is something that controls your access after you have reached the keyboard. Logical access control generally involves identification, authentication, and authorization. The use of a user name and password is a simple form of logical access control.
