In
computing, the
Preboot eXecution Environment (
PXE, sometimes pronounced as
pixie) specification describes a standardized
client-server environment that
boots a software assembly, retrieved from a network, on PXE-enabled clients. On the client side it requires only a PXE-capable
network interface controller (NIC), and uses a small set of industry-standard network protocols such as
DHCP and
TFTP.
