Wireless networks are systems that allow devices to connect and communicate without the need for physical cables. They use radio waves to transmit data, enabling users to access the internet and share information from various locations. Common examples of wireless networks include Wi-Fi networks found in homes and offices, as well as cellular networks used by smartphones. These networks provide convenience and flexibility, allowing people to move freely while staying connected. With the rise of IoT (Internet of Things) devices, such as smart home gadgets, wireless networks have become even more essential in our daily lives, making it easier to control and monitor devices remotely.
