An IEEE 1284 36-pin female on a circuit board. In the 1970s, Centronics developed the now-familiar printer parallel port that soon became a de facto standard.Centronics had introduced the first successful low-cost seven-wire print head [citation needed], which used a series of solenoids to pull the individual metal pins to strike a ribbon and the paper.
Four PCI Express bus card slots (from top to second from bottom: ×4, ×16, ×1 and ×16), compared to a 32-bit conventional PCI bus card slot (very bottom). In computer architecture, a bus (historically also called a data highway [1] or databus) is a communication system that transfers data between components inside a computer or between computers. [2]
2×50 2.54 mm card edge: Designed around Intel 8080 but used with other processors too: Homebrew and industry use. VME: 1981: DIN 41612: 10 MByte/s: Motorola 68000 based: Industry use. STEbus: 1983: DIN 41612 a+c rows? Processor independent based: Industrial quality bus, 8-bit data / 20-bit address. Eurocard sized. Acorn system bus: 1979: DIN ...
Device interfaces where one bus transfers data via another will be limited to the throughput of the slowest interface, at best. For instance, SATA revision 3.0 ( 6 Gbit/s ) controllers on one PCI Express 2.0 ( 5 Gbit/s ) channel will be limited to the 5 Gbit/s rate and have to employ more channels to get around this problem.
Memory bus, a bus between the computer and the memory; PCI bus, a bus between motherboard and peripherals that uses the Peripheral Component Interconnect standard; USB (Universal Serial Bus), a standard communication protocol used by many portable devices, computer peripherals and storage media
ARINC 429 utilizes a unidirectional bus with a single transmitter and up to twenty receivers. A data word consists of 32 bits communicated over a twisted pair cable using the bipolar return-to-zero modulation. There are two speeds of transmission: high speed operates at 100 kbit/s and low speed operates at 12.5 kbit/s.
The ARINC 629 computer bus was introduced in May 1995 and is used on aircraft such as the Boeing 777, Airbus A330 and Airbus A340 [1] [2] as well as the Airbus A320 series. [ 3 ] The ARINC 629 bus operates as a multiple-source, multiple-sink system; each terminal can transmit data to, and receive data from, every other terminal on the data bus.
A unidirectional network (also referred to as a unidirectional gateway or data diode) is a network appliance or device that allows data to travel in only one direction. Data diodes can be found most commonly in high security environments, such as defense, where they serve as connections between two or more networks of differing security ...
