Describe this type of system,in which the features represented by the arrows seems to begin and end at the same point?

This type of system is likely a closed-loop system. In a closed-loop system, the output of the system is fed back into the input, creating a loop of information flow. This allows the system to continuously adjust and improve its performance based on the feedback it receives. The arrows beginning and ending at the same point indicate that the system is self-regulating and self-correcting. This type of system is often used in control systems and feedback control mechanisms to maintain stability and optimize performance.
