PC/104-Plus – COM-1460 Module 35
R
RAM
RAM (Random Access Memory). Semiconductor-based memory that can be read-from and written-to by the
microprocessor or other hardware devices.
ROM
ROM stands for Read Only Memory. This memory can only be read-from but not written-to.
S
SCSI
SCSI stands for Small Computer System Interface. It is an I/O bus designed as a method for connecting
several classes of peripherals to a host system without requiring modifications to generic hardware and
software.
SECAM
SECAM (Sequential Couleur a Memoire; Sequential Colour with Memory). The television standard for
France, Russia, and most of Eastern Europe. As with PAL, SECAM is based on a 50-Hz power system, but it
uses a different encoding process and displays 819 horizontal lines per frame at a scan rate of 25 frames per
second (50 fields per second). See also NTSC and PAL format.
SMBus
SMBus (System Management Bus). A two-wire interface based on the I²C protocol. The SMBus is a low-
speed bus that provides positive addressing for devices, as well as bus arbitration.
SSD
SSD stands for Solid State Disk (i.e. Disk on Chip, Disk on Module, Flash ROM,).
In fact this is not a real disk but a silicon support memory without mechanical parts that are in movement.
U
UART
UART (Universal Asynchronous Receiver/Transmitter), is a module composed of a circuit that contains both
the receiving and transmitting circuits required for asynchronous serial communication.
USB
USB (Universal Serial Bus) is a 4-pin bi-directional, isochronous, dynamically attachable serial peripheral bus
that is capable of cascading low/medium speed peripherals (less than 10 Mbit/s)
V
VGA
VGA Video graphics array. A video adapter that supports 640 × 480-pixel colour resolution. A video display
standard for boot devices under Windows operating systems.
W
WAN
WAN stands for a wide-area network and it is a system of LANs (in geographically separated areas)
connected together via telephone lines and/or radio waves.
