We digress and turn to a real scenario in World War Two. The people who start wars usually transfer their orders to the front from a safe distance.
•The means of information transfer is usually electronic, utilizing the binary digits 0 and 1.
•Suppose a decision has to be made whether the people at the front should do nothing or drop the big bomb. It is agreed that 0 means do nothing, and 1 means drop the big bomb.
