What Is PXE
What is PXE?
PXE is abbreviate of the Preboot Execution Environment.
It is a method of booting a terminal computer (client) using only its online grid card.
It is standards-based and you could use open-source software or vendor-supported products to implement it.
Advantages of PXE
Now, lets see the advantages of using PXE.
The details are as follows:

The standard method for initializing PXE code in PXE ROM chip or boot disk.
How Does It Work
The protocol is divided into client and server.
The PXE client is in the ROM of the connection card.
Here are more details of NIC, the DHCP server, and the TFTP server.
NIC
NIC refers to the connection Interface Controller.
Many consumer-grade connection cards do not have PXE capabilities.
PXE-enabled NIC is the DE facto standard in data center-grade servers.
Some PXE-enabled NICs even use open source PXE firmware.
DHCP
DHCP refers to the Dynamic Host Configuration Protocol.
There are two types of actors in DHCP the DHCP server and the DHCP client.
DHCP supports a wide range of options that can be provided to data pipe clients.
TFTP Server
TFTP refers to the Trivial File Transfer Protocol.
It is a simple UDP-based protocol for getting or sending files.
The simplicity of it is great for implementation in a firmware environment with limited resources.
TFTP has no bells or whistles because of its simple nature.
It only supports getting and putting files.
No directory listing, so you better know the exact path of the file to download.
Besides, there is no authentication or authorization.
Whats more, you’ve got the option to get other information about the PXE boot.
Besides, this post introduces how it works.
