A wireless network is a type of computer network that allows devices to connect and communicate without physical cables. Instead of using wires, it relies on radio waves or infrared signals to transmit data. This technology enables devices like laptops, smartphones, and tablets to access the internet and share information easily. Wireless networks are commonly used in homes, offices, and public spaces. They typically involve a central device called a router, which connects to the internet and broadcasts the signal to nearby devices. This setup provides convenience and mobility, allowing users to move freely while staying connected.
