Answer Posted / Shuchi Garg
The main problem with busy waiting (polling) is that it leads to inefficient use of system resources. By continuously checking for an event, the processor spends a significant amount of time in idle loops instead of performing other tasks. This can cause the CPU to waste resources, and may lead to issues such as increased power consumption, reduced responsiveness, and even thread starvation.
