Explanation:
Access is the ability to do something with a computer resource (e.g., use, change, or view). Access
control is the means by which the ability is explicitly enabled or restricted in some way (Usually
through physical and system-based controls). Computer-based access controls can prescribe not
only who or what process may have access to a specific system resource, but also the type of access
that is permitted. These controls may be implemented in the computer system or in external
devices.
