What is the difference between analog and digital media?

The distinction between analog and digital media primarily revolves around how they capture and represent information. Analog media captures physical signals, such as sound waves or light, in a continuous form. This means that the information is stored in the same way that it is perceived in the real world, usually through variations in amplitude, frequency, or wavelength. For example, vinyl records or cassette tapes are analog formats that represent sounds through variations in grooves or magnetic tape.

In contrast, digital media encodes data into a format that represents discrete values—typically using binary code, which consists of bits (0s and 1s). This encoding allows for easier manipulation, storage, and transmission of data. Digital formats include CDs, MP3s, and digital video files, all of which translate those physical signals into numerical data that can be processed by computers.

The other options do not accurately highlight the fundamental differences in how analog and digital media function and their inherent characteristics. Understanding this core difference is essential in various applications, from audio and video production to data storage and transmission technologies.
