What kind of memory is ROM, and why is it essential in a computer syst...
ROM (Read Only Memory) is a non-volatile memory type crucial for storing essential information necessary to boot and operate a computer system. Unlike RAM (Random Access Memory), which is volatile and loses its contents when the power is turned off, ROM retains its data even when the computer is shut down. This characteristic makes ROM vital for storing critical instructions and data that need to be preserved across power cycles. ROM is like a computer's long-term memory, ensuring that fundamental information is always available for the system to function properly.

Direction:In many of the process control applications, the purpose of control system is to keep the output (controlled variabl e) almost constant in spite of changes in load. Mostly in continuous processes the set point remains constant for longer time. Such an operation is called Regulator Operation. The set point generated, and the actual values from sensors are given to a controller. The controller compares both the signals, generates error signal which is utilized to generate a final signal as controller output. The controller output is finally utilized to physically change the values of manipulated variable to achieve stability. The above action is achieved with the help of final control elements. They are operatable either with electrical, pneumatic or with hydraulic signals. The system that serves good for servo operation will generally not be the best for regulator operation. Large capacity or inertia helps to minimize error here, whereas it makes the system sluggish in case of servo operation.Q.Which out of these is not the operational signal for control system ?
