A continuous process is a process that is carried out without interruption. Raw materials enter the process and an identifiable product exits the process. The process is typically automated and controlled by a computer. Continuous processes are often used in manufacturing, chemical processing, and oil refining.
Option A is incorrect because continuous processes can be used for complex tasks as well as simple tasks.
Option B is incorrect because continuous processes do shut down for maintenance and repairs.
Option C is correct because continuous processes are self-contained in that raw materials enter the process and an identifiable product exits the process.
Option D is incorrect because continuous processes can be used with both analog and digital controllers.
Option E is incorrect because continuous processes are a type of process, not a type of controller.
