Final answer:
Most personal computers use discretionary access control, allowing the system owner or administrator to manage access to resources.
Step-by-step explanation:
Most personal computers use discretionary access control. Discretionary access control (DAC) is a type of security protocol that allows the owner or administrator of the system to set policies for who can access specific resources. This is in contrast to mandatory access control (MAC), which is enforced by a strict policy that cannot be altered by end users; role-based access control (RBAC), which assigns access based on the role within an organization; and task-based access control (TBAC), which grants permissions to perform specific tasks. Most personal computers use discretionary access control.
Discretionary access control (DAC) allows the owner or administrator to control access to resources, such as files and folders, by granting or revoking permissions based on user identity and the sensitivity of the resource. In DAC, the owner of the resource determines who can access it and what level of access they have. This type of access control is commonly used on personal computers as it provides flexibility and control to individual users.
