SSD (Solid State Drive)
A Solid State Drive is a drive that can be installed like any other drive; it does not contain a
rotating disk or other moving parts because only semiconductor memory chips of similar
capacity will be used. This design makes SSDs more rugged, provides shorter access times,
low energy consumption and rapid data transfer.
STEP 7
Programming software for the creation of user programs for SIMATIC S7 controllers.
Track-At-Once
In track-at-once recording, a CD can be written to in bits in several sessions if the CD was
not closed.
Troubleshooting
Error cause, cause analysis, remedy
Trusted Execution Technology
Hardware implementation that allows secured execution of programs and applications. It is
only effective when all relevant system components, such as processors, operating systems
and applications are supported.
Turbo Mode
In this mode individual processor cores can be clocked higher in accordance with the load
from the user programs and as required. It is only supported by Core i5 and Core i7
processors.
V.24 interface
V.24 is a standardized interface for data transfer. Printers, modems, and other hardware
modules can be connected to a V.24 interface.
Wake on LAN (WoL)
Wake on Local area network. This function allows the PC to be started via the LAN interface.
Warm restart
The restart of a computer after a program was aborted. The operating system is loaded and
restarted again. The CTRL+ ALT+ DEL hotkey can be used to initiate a warm restart.
