Transmission methods refer to the various ways information or energy is conveyed from one point to another. Common methods include wired transmission, where signals travel through physical cables, and wireless transmission, which uses radio waves or other electromagnetic signals. Each method has its advantages and disadvantages, such as speed, range, and reliability. In telecommunications, modulation techniques are often employed to enhance transmission efficiency. For example, amplitude modulation (AM) and frequency modulation (FM) are used in radio broadcasting. Additionally, fiber optics is a popular method for high-speed data transmission, utilizing light signals to transmit information over long distances with minimal loss.
