 * The Difference Between Analog and Digital Data **

The difference between analog and digital data is that analogue are signals that repetitive in time and level. However, digital signals are also repetitive in time, but discrete in level. Analog data is the data which is stored in the form of waves although, digital data is data which is stored in the form of binary numbers. For those who do not know what binary numbers are, it is a system that represents numerical values. An analog is the procedure of taking and audio or video signal, like human voices. It then translates it into electronic pulses. Analog signals are constantly varying while digital data is based on binary form. For example, if a light switch was on or off that would be digital, but if is was a dimmer switch in would be an analog. Another example, would be that a clock in which the second hand moves smoothly around the face it would be and analog. However, in another clock, the hand jumps every second it would be digital. Digital data is when you break the signal into binary format. In other words it breaks your voice in to binary code. This is where audio and video data is presented in a series of 1s and 0s. For example, digital phones, fax and modems. Phone Lines: There are digital phone lines that are found in corporate phone systems. Digital lines normally carry lower voltages other than analog lines. Analog Lines: Are referred to POTS(Plain Old Telephone Service). Analog lines pose a threat to you analog equipment such as, standard phones, fax, machines and modems. These lines are usually found in your house or office.
