• DDR4 SDRAM.
Double data rate four synchronous dynamic random access memory. A type of RAM
used for image capture and processing.
See also RAM.
• Display memory.
Display memory is a dedicated storage area used for displaying data. Since a
computer sends out data faster than a screen can display it, the data is temporarily
stored in display memory. By default, the display memory is set to 32 Mbytes in
the UEFI.
• Driver.
A software program that services an operating system so that the operating system
can use a hardware device.
• Earth ground.
Earth ground is the reference point in an electrical circuit from which voltages are
measured, a common return path for electric current, or a direct physical
connection to the Earth.
• Ethernet.
The most common standard for the physical wiring and signaling on a local area
network (LAN). A Gigabit Ethernet LAN supports data transfer at rates of
10 Mbits/sec, 100 Mbits/sec,or 1000 Mbits/sec, for Fiber Ethernet. In addition,
2.5 Gbits/sec, 5 Gbits/sec, and 10 Gbits/sec are supported for Ethernet over
Copper.
See also LAN.
• Inductive load devices.
Inductive load devices include all forms of external devices that have inductor
wiring, such as a relay or small motor. Devices connected to an inductive load
device require a diode to protect them from over-voltage.
