Extensible Firmware Interface
Refers to the central interface between the firmware, the individual components of a
computer and the operating system. EFI is located logically beneath the operating system
and represents the successor to PC BIOS, focusing on 64-bit systems.
File Based Write Filter
Configurable write filter to protect individual files from write access.
Formatting
Basic partitioning of memory space on a magnetic data medium into tracks and segments.
Formatting deletes all data on a data medium. All data media must be formatted prior to their
first use.
HORM
Hibernate once, resume many is a method for fast booting from a single Hibernate file that
only needs to be created once. HORM ensures restoration of a uniform, saved system state
when booting. This minimizes write access, for example to a CompactFlash medium, when
you start up and shut down Windows Embedded Standard 7.
Hub
A term in network technology. In a network, a device joining communication lines at a central
location, providing a common connection to all devices on the network.
Hyper Threading
HT technology (multi-threading) enables the parallel computing of processes. HT is only
effective when all relevant system components, such as processors, operating systems and
applications are supported.
IGD
Integrated Graphics Device. Graphics interface integrated in the chipset.
Image
This refers to the image, for example, of hard disk partitions saved to a file in order to restore
them when necessary.
Intel Active Management Technology
This technology permits the diagnostics, management and remote control of PCs. It is only
effective when all relevant system components, such as processors, operating systems and
applications are supported.
