Energy management
The energy management functions of a modern PC allow individual control over the current
consumption of vital computer components (e.g. of the monitor, hard disk and CPU), by
restricting their activity based on the current system or component load. Energy
management is of particular importance for mobile PCs.
Energy options
The energy options can be used to reduce energy consumption of the computer, while
keeping it ready for immediate use. This can be configured in Windows by selecting Settings
> Control Panel > Energy options.
ESD directive
Directive for using electrostatic sensitive components.
Ethernet
Local network (bus structure) for text and data communication with a transfer rate of
10/100/1000 Mbps.
Execute Disable Capability
Hardware implementation that prevents mutual memory accesses by programs and
applications. It is only effective when all relevant system components, such as processors,
operating systems and applications are supported.
Extensible Firmware Interface (EFI)
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 (FBWF)
Configurable write filter to protect individual files from write access.
Formatting
Basic partitioning of memory space on a magnetic data medium into tracks and sectors.
Formatting deletes all data on a data medium. All data media must be formatted prior to their
first use.
