Radio

In computer science, „Radio“ typically refers to a digital communication technology that transmits data wirelessly over radio waves. This form of communication is employed in various applications, including wireless networks, mobile devices, and Internet of Things (IoT) devices. Radio technology enables devices to send and receive data without the need for physical cables, relying instead on modulated electromagnetic waves.

Radio can encompass various protocols and standards, such as Wi-Fi, Bluetooth, and cellular networks, each designed for specific use cases and ranges. It allows for different modulation techniques and frequency bands to optimize for distance, data rate, and power consumption. In the context of user interface design, a „radio button“ is a UI element that allows users to select one option from a set, resembling the functionality of old car radios where only one station could be tuned in at a time.

Overall, radio plays a crucial role in enabling wireless connectivity and communication across numerous devices and applications in the field of computer science and technology.
