Homework Questions 1. Describe analog and digital data. They are both types of data that have been changed into a transmittable form to be sent over a network. Analog data has a non-stop, conyinuous nature; such as continuously fluctuating temperatures. Digital data has separate ‘pulsing’ states used to represent information. For example, if you were sending 3 maps; your data would stop and start 3 times. 2. Explain the difference between analog and digital signals. Give an example of each in your definition. Analog signals send continuously fluctuating data in which ALL values are meaningful. (The hour, minute, AND seconds on an analog clock in a continuous signal stream). Digital signals, on the other hand, are signals that are sent with values where data is noted at fixed intervals (for example, every millisecond) and each noted piece of data comprises the signal. (The hour and minute of a digital clock, with the signal having noted stopped and started values of data at minute intervals).
