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.
Gender changer
Using the gender changer (25-pin/25-pin), the COM1/V24/AG interface of the SIMATIC IPC
family can be converted into the usual 25-pin male connector.
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 reduces the writing to a CompactFlash medium to a minimum, for
example, when starting up and shutting down Windows Embedded Standard 2009.
Hot plug
The SATA interface gives the device's hard drive system hot plugging capability. Prerequisite
for this configuration is a RAID1 system with SATA RAID controller (onboard, or slot
module), and at least two SATA removable frames. The advantage of hot plugging is that
defective hard disks can be replaced without having to reboot the computer.
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.
