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 [1] (historically also called data highway [2] or databus) is a communication system that transfers data between components inside a computer, or between computers.
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 ...
Along the Portland Transit Mall in downtown Portland, FX buses travel in lanes dedicated to transit buses and light rail vehicles, separated from private vehicle traffic. [ 9 ] [ 10 ] FX2–Division travels the remainder of its route through Division Street in mixed traffic, but it uses transit signal priority to move quickly.
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.
The following is a list of presently-operating bus transit systems in the United States with regular service. The list excludes charter buses, private bus operators ...
[5] [18] These hybrid buses proved to be useful, at least the 2006-2007 models, for these models cost significantly less to repair and maintain than earlier units. [20] As of December 2022, the fleet has over 1,100 diesel-electric buses and over 700 buses powered by compressed natural gas, which make up less than half of the total fleet.
The following is a list of local bus agencies in the United States, ranked by ridership. All figures are unlinked passenger trips for the stated time period and come from the Federal Transit Administration 's National Transit Database (NTD).
The 8086 [3] (also called iAPX 86) [4] is a 16-bit microprocessor chip designed by Intel between early 1976 and June 8, 1978, when it was released. The Intel 8088, released July 1, 1979, [5] is a slightly modified chip with an external 8-bit data bus (allowing the use of cheaper and fewer supporting ICs), [note 1] and is notable as the processor used in the original IBM PC design.
