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 3Gb/s 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.

USB

The Universal Serial Bus (USB) is an external bus standard for

interfacing devices. USB 1.1 supports 12Mbps data transfer rates, while
