Wireless protocols are standardized methods that allow devices to communicate without physical connections. They define how data is transmitted over the air, ensuring that devices can send and receive information effectively. Common examples include Wi-Fi, which connects devices to the internet, and Bluetooth, which enables short-range communication between devices like headphones and smartphones. These protocols use radio waves to transmit data, making them essential for modern technology. Each protocol has its own specifications regarding speed, range, and security. Understanding these protocols helps users choose the right technology for their needs, whether for home networking or connecting personal devices.
