Question

Quizplus · Accepted Answer

The process of determining the identity of a user or system and deciding whether or not to grant access is called authentication. Once the user is authenticated, the computer then applies authorized levels of access, determining what actions the user can perform. Decryption is the process of converting encrypted data back into its original form. Encryption is the process of converting data into a secure format to prevent unauthorized access. Transparency refers to the quality of a system that operates without the user's awareness. None of these are directly related to determining and managing user access to a computer.
