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]
Bus (computing), a communication system that transfers data between different components in a computer or between different computers 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
A bilingual dictionary or translation dictionary is a specialized dictionary used to translate words or phrases from one language to another. Bilingual dictionaries can be unidirectional, meaning that they list the meanings of words of one language in another, or can be bidirectional, allowing translation to and from both languages ...
ARINC 429, [1] the "Mark 33 Digital Information Transfer System (DITS)," is the ARINC technical standard for the predominant avionics data bus used on most higher-end commercial and transport aircraft. [2] It defines the physical and electrical interfaces of a two-wire data bus and a data protocol to support an aircraft's avionics local area ...
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 system bus is a single computer bus that connects the major components of a computer system, combining the functions of a data bus to carry information, an address bus to determine where it should be sent or read from, and a control bus to determine its operation. The technique was developed to reduce costs and improve modularity, and ...
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.
In computer architecture, a control bus is part of the system bus and is used by CPUs for communicating with other devices within the computer. While the address bus carries the information about the device with which the CPU is communicating and the data bus carries the actual data being processed, the control bus carries commands from the CPU and returns status signals from the devices.
