Wireless communication is a method of sending data from one location to another without using physical mediums such as cables or wires. This is achieved through the use of wireless networks, which use radio frequency waves to transmit data through the airwaves. In contrast, wired communication involves the use of physical mediums such as copper wires, fiber-optic cables, or coaxial cables to transmit data. While wired communication is generally faster and more reliable, wireless communication provides the flexibility of mobility and convenience, making it the preferred choice for many applications such as mobile communication, internet access, and IoT devices.
