In today's world, everything seems connected. Think of how the future would be... "Internet of things" is the concept of communication of the smart gadgets and devices like computer, phones, watches, appliances etc. Provide two illustrations on how "IoT" could make our lives easier in the near future.

IoT is a booming concept at the moment. There are however many ideas implemented already. Some of them are : 1. Smart AC is connected through wifi. Reads the message sent by me to turn itself on as I am about to reach home in 15 minutes. 2. The car senses the speed limit board on the road and adjusts the speed or beeps to notify the driver.

Provide an example of a concept used in computer networks inspired from nature.

There could be more than one answers to this question. The best I can think of as of now is "Piggy Backing". Like a crow takes a ride behind pigs back, the data packets carry the information - "Acknowledgement" by the receiver to the sender. It is an efficient way to let the sender know that the last sent packet is received by the receiver.

According to ANSI C, what is the smallest program that you could write in 'C programming'?
