Turning to Bits Your local council has installed a public access WiFi system. It monitors the quality of the service by measuring the strength of the WiFi signal at 20 locations. Every 10 minutes, it receives a sequence of 3 bits from each location. This is essentially a number that indicates how strong the signal is: 000 001 010 011 100 101 110 111 (000 being low signal and 111 being high signal) How many bits are received from each location in one day? You may need to use a calculator for this question.
