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.
SATA Serial ATA (SATA) is a serial communications bus designed for data
transfers between storage devices and the computer chipsets. The
SATA Revision 1.x bus has transfer speeds up to 1.5 Gbps and the
SATA Revision 2.x bus has data transfer speeds of up to 3.0 Gbps.
S.M.A.R.T Self Monitoring Analysis and Reporting Technology (S.M.A.R.T) refers
to automatic status checking technology implemented on hard disk
drives.
UART Universal Asynchronous Receiver-transmitter (UART) is responsible for
asynchronous communications on the system and manages the
system’s serial communication (COM) ports.
UHCI The Universal Host Controller Interface (UHCI) specification is a
register-level interface description for USB 1.1 Host Controllers.
