A wireless network is a type of computer network that allows devices to connect and communicate without physical cables. It uses radio waves or infrared signals to transmit data between devices, such as computers, smartphones, and tablets. This technology enables users to access the internet and share information conveniently from various locations. The most common type of wireless network is the Wi-Fi network, which is widely used in homes, offices, and public spaces. Devices connect to a central device called a router, which manages the network and provides internet access. Wireless networks offer flexibility and mobility, making it easier for users to stay connected.
