Digital signals are representations of data that use discrete values, typically in the form of binary code (0s and 1s). Unlike analog signals, which can vary continuously, digital signals maintain specific levels, making them more resistant to noise and interference. This characteristic allows for clearer transmission of information over long distances. In modern technology, digital signals are essential for various applications, including computers, telecommunications, and audio/video broadcasting. They enable efficient data processing and storage, allowing devices to communicate and share information seamlessly. As a result, digital signals play a crucial role in the functioning of the internet and other digital systems.
