memory.
DIMM
Dual Inline Memory Modules are a type of RAM that offer a 64-bit data
bus and have separate electrical contacts on each side of the module.
EHCI
The Enhanced Host Controller Interface (EHCI) specification is a
register-level interface description for USB 2.0 Host Controllers.
GbE Gigabit Ethernet (GbE) is an Ethernet version that transfers data at 1.0
Gbps and complies with the
2
IEEE 802.3-2005 standard.
GPIO
General purpose input
IrDA Infrared Data Association (IrDA) specify infrared data transmission
protocols used to enable electronic devices to wirelessly communicate
with each other.
L1 Cache The Level 1 Cache (L1 Cache) is a small memory cache built into the
system processor.
L2 Cache
The Level 2 Cache (L2 Cache) is an external processor memory cache.
LVDS
Low-voltage differential signaling (LVDS) is a dual-wire, high-speed
differential electrical signaling system commonly used to connect LCD
displays to a computer.
MAC The Media Access Control (MAC) protocol enables several terminals or
network nodes to communicate in a LAN, or other multipoint networks.
PCIe
PCI Express (PCIe) is a communications bus that uses dual data lines for
full-duplex (two-way) serial (point-to-point) communications between the
SBC components and/or expansion cards and the SBC chipsets. Each
line has a 2.5 Gbps data transmission rate and a 250 MBps sustained
data transfer rate.
POST
The Power-on Self Test (POST) is the pre-boot actions the system
performs when the system is turned-on.
QVGA Quarter Video Graphics Array (QVGA) refers to a display with a
resolution of 320 x 240 pixels.
RAM
Random Access Memory (RAM) is a form of storage used in computer.
RAM is volatile memory, so it loses its data when power is lost. RAM has
very fast data transfer rates compared to other storage like hard drives.
