Electricity How has electricity today changed from the past?

1. How do electronic devices transmit information? 2. How do computers receive information? 3. Why have computers gotten smaller over the years?

Electronics All electronic devices transmit information using signals. One type of signal is called ‘binary code’ which uses 1’s and 0’s to tell the device when electrical pulses are coming through the system. 1’s are when the pulse is on and 0’s are when the pulse is off. How would you write a code where there is one pulse, followed by three ‘no’ pulses, and then one pulse?
