L2 Cache The Level 2 Cache (L2 Cache) is an external processor memory cache.
LCD Liquid crystal display (LCD) is a flat, low-power display device that
consists of two polarizing plates with a liquid crystal panel in between.
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.
RAID Redundant Array of Inexpensive Disks (RAID) refers to redundantly
backing up data on multiple disks to ensure that if one disk fails, the data
is not lost and can be restored from the remaining disks in the array.
RAM Random Access Memory (RAM) is volatile memory that loses 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.
