PXE (Preboot Execution Environment) is a protocol that allows a computer to boot from a network location, rather than from a local hard drive. In SCCM, PXE is used to deploy operating systems to computers. When a computer boots from a PXE-enabled network, it downloads a boot image and then contacts the SCCM server to retrieve the necessary files for deployment.
