PXEPXE

PXE, which stands for Preboot Execution Environment, is a standard for network booting computers. It allows a computer to boot and load an operating system over a network, using a device called a PXE server. This means that a computer can be booted and configured without the need for a physical hard drive or compact disc.

PXE was originally developed by Intel as a boot protocol for PXE-enabled network interface cards. It has since become a widely used standard for network booting, supported by many operating systems and hardware devices. PXE clients typically consist of a network interface card with a PXE-enabled chip, which listens for a DHCP (Dynamic Host Configuration Protocol) offer from a server. Once contacted by the client, the PXE server provides the client with a network address and boot files.

PXE is commonly used in enterprise environments, such as data centers and server rooms, where deploying and managing operating systems across a large network can be a complex task. PXE allows administrators to define a network-based boot environment, allowing multiple devices to boot and load their respective operating systems from a single source. This can be particularly useful for remotely managing hardware devices, upgrading or repairing operating systems, and automating server deployments. The use of PXE has also reduced the need for physical media, such as DVDs or USB drives, making the process of deploying and managing operating systems more efficient and cost-effective.
