Wireless Networks Questions Medium
A wireless network works by using radio waves to transmit and receive data between devices. It consists of two main components: the wireless router or access point and the wireless devices such as laptops, smartphones, or tablets.
The wireless router acts as a central hub that connects to the internet through a wired connection, such as a broadband modem. It then broadcasts the internet signal wirelessly using radio waves. The router has an antenna that emits these radio waves in all directions, creating a coverage area known as a wireless network.
Wireless devices within the range of the router can detect and connect to the network. They have built-in wireless network adapters that receive the radio waves and convert them into data that can be understood by the device. This allows the devices to access the internet and communicate with other devices on the network.
When a device wants to send data, such as browsing a website or streaming a video, it converts the data into radio waves and transmits them to the router. The router then forwards the data to the internet through the wired connection. Similarly, when the router receives data from the internet, it converts it into radio waves and transmits it to the appropriate device.
To ensure secure communication, wireless networks often use encryption protocols such as WPA2 (Wi-Fi Protected Access 2) to encrypt the data being transmitted. This prevents unauthorized access to the network and protects the privacy of the users.
Overall, a wireless network allows devices to connect to the internet and communicate with each other without the need for physical cables. It provides flexibility and convenience, enabling users to access the internet from anywhere within the network's coverage area.
