What do they mean?
Boot Integrity Services (BIS): Boot Integrity Services were set up to fill the need for security in boot images. It provides a mechanism to validate the origin and integrity of information that is downloaded before an operating system is installed. Using BIS, firmware built into the client PC can validate the boot image before executing it to ensure its source and content.
Pre-boot eXecution Environment (PXE): Intel´s Preboot Execution Environment is a technology standard that provides a mechanism for connecting to the network and executing program code by booting directly from a network interface card (NIC).
Wake on LAN (WOL): WOL is a technology that allows a network professional to remotely power on a computer or to wake it up from sleep mode. By remotely triggering the computer to wake up and perform scheduled maintenance tasks, the technician does not have to physically visit each computer on the network. To use Wake on LAN technology you need a WOL network adaptor, WOL-enabled motherboard, and remote management software. The WOL network adaptor continually monitors the network looking for wake-up frames. The adaptor must have a constant power source in order to boot up, which is usually from a special power supply that delivers a certain amount of power continually. The WOL adaptor also decodes the wake-up frame to determine if it is a wake-up. The key to determining a wake-up frame is if the MAC address is repeated 16 times without breaks or interruptions.
