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 bus has transfer speeds up to 1.5 Gbps and the SATA II 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
