Explanation:
Detailed explanation-1: -In computer science, polling or a polled operation denotes the process of repeatedly sampling the status of external devices by a client program. The term polling is often used when describing input/output and referred to as software-driven I/O or polled I/O. This process can occur thousands of times a second.
Detailed explanation-2: -Disadvantages of Polling and Interrupt Disadvantages of polling are the standby time of some devices that is shorter than the response time and then another method of transmission should be applied, as well as that the CPU consumes unnecessary time to check devices that have not searched for data transfer.
