Which of the following is NOT a typical component utilized in access control?

Access control is a fundamental aspect of security mechanisms within an operating system, as it determines who can access or modify resources and under what circumstances. Typical components utilized in access control usually include hardware devices, administrative accounts, and network interfaces.

Hardware devices are essential for access control as they can enforce security measures, such as biometric scanners or security tokens that restrict access to systems based on physical attributes or possession of specific devices. Administrative accounts are critical for managing access rights and permissions, providing a way for designated individuals to control user access levels within a system. Network interfaces also play a significant role in access control, facilitating the regulation of data transfer and verifying user identities over networks.

In contrast, processing units, while crucial for executing system operations, do not directly relate to managing or controlling access to resources. They handle computation and processing tasks rather than serving as a mechanism or tool for determining access permissions. This distinction clarifies why processing units do not fit the typical components involved in access control systems.
