A WLAN, or Wireless Local Area Network, is a technology that allows devices to connect to the internet or communicate with each other without physical cables. It uses radio waves to transmit data, enabling users to access the network from various locations within a limited area, such as homes, offices, or public spaces. WLANs are commonly implemented using Wi-Fi standards, which define how devices connect and communicate wirelessly. This technology provides flexibility and convenience, allowing multiple devices like laptops, smartphones, and tablets to connect simultaneously, enhancing productivity and user experience in both personal and professional settings.
