Access control plays a crucial role in security by regulating who can enter or exit a facility. This function helps ensure that only authorized individuals are granted access to specific areas, thereby protecting sensitive information, assets, or personnel. By implementing access control measures, such as identification systems, key cards, or biometric scanners, organizations can effectively manage the flow of individuals within their premises. This helps in preventing unauthorized access, enhancing overall safety, and maintaining an environment conducive to security protocols.

The other choices do not align with the primary goals of access control. Limiting the number of employees, for instance, may not address the fundamental purpose of controlling access effectively; rather, it's more about managing personnel. Encouraging loitering is contrary to the principles of security, which often aims to deter unnecessary presence within a facility. Gathering personal information is important for security screenings but is not the primary function of access control; rather, access control focuses on the permission to enter specific areas.
