Analog technology refers to systems that use continuous signals to represent information. Unlike digital technology, which uses discrete values (like 0s and 1s), analog devices can capture a range of values. Common examples include vinyl records, analog clocks, and thermometers that use liquid to measure temperature. These technologies work by directly measuring physical quantities, such as sound waves or light intensity. For instance, an analog microphone converts sound waves into electrical signals that vary continuously. While digital technology has become more prevalent, analog devices are still valued for their simplicity and ability to provide a more natural representation of certain types of data.
