What Is the Sleep Function

Sleep plays an important role in the function of the brain, by forming new pathways and processing information. Research has shown that adequate sleep helps to improve memory and learning, increase attention and creativity, and aid in making decisions.

How sleep is implemented?

Sleep() is implemented at the OS level. The processor doesn’t spin when a task/thread/process is sleeping. That particular thread is put on a pending queue (the thread isn’t ready to run) until the time has expired at which point the thread will be placed on the ready to run queue.

What is the use of sleep function in IoT?

A wireless IoT “thing” sleeps, senses and connects. How efficiently it does these tasks impacts energy consumption, which also involves design tradeoffs between functionality, size, and battery lifetime.
