Network Boot is a process that allows a computer to start up and load its operating system from a server rather than from a local hard drive. This is particularly useful in environments where multiple computers need to be managed centrally, such as in schools or businesses. The computer connects to the network and retrieves the necessary files to boot up. During the Network Boot process, the computer uses a protocol like PXE (Preboot Execution Environment) to communicate with the server. Once connected, it downloads the operating system image and configuration settings, enabling it to operate without local storage. This method simplifies updates and maintenance across multiple devices.
