What technology eliminates the need for physical network connections by using radio waves?

The technology that eliminates the need for physical network connections by using radio waves is wireless technology. This method transmits data over the air, allowing devices to communicate without the need for cables or physical connectors. Wireless networks are commonly used in various applications, such as home Wi-Fi networks, cellular networks, and other forms of communication where mobility and flexibility are essential.

Wireless technology relies on radio frequency (RF) signals to transmit data, which enables devices like laptops, smartphones, and tablets to connect to the internet or each other from a distance. This capability fosters a more dynamic and convenient networking environment, making it suitable for both personal and business applications.

In contrast, wired networks necessitate physical connections through cables, while fiber optics utilize light to transmit data over long distances through fiber strands. Satellite technology also relies on radio waves, but it is specifically designed for satellite communications, typically involving longer distances and coverage areas compared to standard wireless networks. Therefore, the option that most accurately reflects the use of radio waves to eliminate physical connections is wireless technology.
