This mechanism allows the computer to start without relying on a local data storage device (such as a hard disk) or a locally installed operating system.

two。 Technology announced by Intel and Systemsoft on September 20, 1999

The working mode of 3.C/S

The 4.PXE client invokes network protocols such as Internet Protocol (IP), user data Protocol (UDP), dynamic Host allocation Protocol (DHCP), small File transfer Protocol (TFTP), and HTTP.

The PXE protocol generally combines DHCP and TFTP, although there are improvements in both. DHCP is used to find the appropriate boot server, and TFTP is used to download the initial bootstrap and additional files.
