Digital cables are specialized wires designed to transmit digital signals between devices. They convert data into a format that can be easily understood by electronic equipment, such as computers, televisions, and audio systems. Common types of digital cables include HDMI, USB, and optical cables, each serving different purposes and supporting various formats. These cables ensure high-quality transmission of audio and video signals without significant loss of quality. For instance, HDMI cables are widely used to connect DVD players and gaming consoles to TVs, while optical cables are often used for high-fidelity audio connections.
