Abbreviation Term Definition
EIDE Enhanced Integrated Drive Electronics An enhancement of the IDE standard. Enhanced
IDE is the standard for a hardware interface. This
interface is designed for disk drives operating
with internal disk drive controllers. This allows
standardization of interfaces for the system,
ensuring enhanced functions (e.g. burst packet
transfer and direct data access.)
EISA Extended Industry Standard Architecture Enhanced ISA standard, introduced to the market
in the year 1988; based on 32-bit data bus and
24-bit address bus;
Competitor to the IBM 32-bit bus system MCA.
EMM Expanded Memory Manager Manages memory expansions
EM64T Extended Memory 64 technology Processor works with 64 Bit data capacity.
Dependant on application, this can provide
increased performance. In order to use all of the
advantages, the operating system, drivers and
applications must support 64 bit operation.
EN European standard
EPROM / EEPROM Erasable Programmable Read-Only
Memory / Electrically Erasable
Programmable Read-Only Memory
Plug-in submodules with EPROM/EEPROM
chips. S5/S7 user programs can be permanently
stored on them, for example. This programmed
module is then inserted into the prepared slots of
the PCs / automation devices / PLCs.
EPP Enhanced Parallel Port Bi-directional Centronics interface
ESC Escape Character Control character
EWF Enhanced Write Filter
