What type of communications technology tends to support higher transmission speeds?

The correct answer is digital networks because they are designed to transmit data in binary form (0s and 1s), which allows for more efficient and faster data transfer compared to analogue systems. Digital networks utilize digital signals that can be easily encoded, manipulated, and transmitted over various media, including copper wires and optical fibers. As a result, they support higher transmission speeds and are more capable of handling large volumes of data with less distortion and interference.

Analogue networks, by contrast, transmit data in continuous waveforms, which can lead to a degradation of signal quality over distances, thus limiting their speed and capacity. Wireless networks can vary in speed depending on the specific technology used, such as Wi-Fi or cellular networks, but do not inherently guarantee higher speeds than digital networks. Fiber-optic networks represent a specific type of digital network that offers the highest transmission speeds due to the properties of light used for communication, but they fall under the broader category of digital networks. Therefore, while digital networks encompass various technologies, they are predominantly known for their ability to achieve higher transmission speeds.
