PXE

PXE, or Preboot Execution Environment, is a technology that allows computers to boot up and load an operating system over a network instead of from a local storage device like a hard drive or USB. When a computer starts, it contacts a network server to download the necessary files to start the operating system. This process is useful in managing multiple computers efficiently, such as in large organizations or data centers, because it simplifies software deployment, maintenance, and recovery without needing physical access to each machine.
