PC/104-Plus – CPU-1461 Module 65

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.

TDMA

Time Division Multiple Access is a technology for delivering digital wireless service using time division multiplexing, that is a type of multiplexing combining data streams by assigning each stream a different time slot in a set.

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)
