The correct answer is: D. All of the above.
Invoicing systems, payroll systems, and process control systems are all computing systems designed to supply supervisory information.
Invoicing systems are used to create and send invoices to customers. They track the sales of products or services and generate invoices that include the customer’s name, address, and contact information, as well as the product or service sold, the quantity sold, and the price.
Payroll systems are used to calculate and pay employee wages. They track employee hours worked, pay rates, and deductions, and generate paychecks that include the employee’s name, address, and contact information, as well as the amount of wages earned and the amount of taxes and other deductions withheld.
Process control systems are used to monitor and control industrial processes. They collect data from sensors and use it to control the process, such as by adjusting the temperature, pressure, or flow of materials.
All of these systems provide information that is used to supervise and control operations.
