  Bus (computer) - MSN Encarta
In computer architecture, a bus is a subsystem that transfers data between computer components inside a computer or between computers.
Bus (computer), in computer science, a set of wires used for data transfer among the components of a computer system.
Because the bus is integral to internal data transfer and yet computer users often need to add extra components to the system, most microcomputer buses allow for expansion through one or more expansion slots (connectors for add-on circuit boards).

 Method and system for avoiding live lock conditions on a computer bus by insuring that the first retired bus master is ...
The bus controller may prevent execution of the transaction request from the other bus masters by transmitting retry commands to all bus masters that submit transaction requests after the transaction request from the first bus master is received and before the first bus master re-submits the transaction request.
The computer system of claim 14 wherein the bus controller includes a bus interface and a buffer associated with the target device, the bus interface determining whether the target device is available to execute the first transaction request by determining whether the buffer is in a state that enables execution of the first transaction request.
Bus master 1 re-submits its second read transaction request and the PCI target interface processes it normally because the write buffer is still empty and the bus master 1 no longer has an ineligible flag associated with it.

  Computer bus: Definition and Links by Encyclopedian.com
In computer architecture a bus is a subsystem that transfers data or power between computer components inside a computer or between computers.
Early computer buses were literally parallel electrical buses with multiple connections, but the term is now used for any physical arrangement that provides the same logical functionality as a parallel electrical bus.

 Lesson 2: The Computer Bus
Remember, in a computer, a bus is a set of parallel wires or lines to which the CPU, the memory, and all input/output devices are connected.
When we speak of buses within a computer (data bus, expansion bus, or address bus), we are speaking of a specific number of wires dedicated to a specific purpose – connecting parts of the computer to each other for the exchange of data between components.
A bus is the physical means by which data is made to move inside a computer.

The computer selects the most reliable bridge for the bus based on the bus bridges available to the computer and a user-determined hierarchy of bus bridges (e.g., traditional telephone line selected in preference to a cellular telephone connection).
The remote linkable bus operates in such a way that the user does not have to change how he or she uses the computer in order to access the entire bus; whether in the office or on the road, the full functionality of the bus is available to the user.
one segment of the bus that resides with the computer's central processing unit (CPU) 14 is referred to as the local bus segment loa of the remote linkable bus.

 Hot plug connected I/O bus for computer system - Patent 6070207
Bus expander bridges 80A and 80B are connected to MIOC 100 via expander buses 70A and 70B, respectively.
Bus drivers or transceivers can be disabled by tri-stating their outputs (e.g., for CMOS drivers) or by leaving the transceivers in the undriven state (e.g., for open drain drivers).
Placing the bus system in an operational mode can include for example, enabling the bus drivers in the MIOC 100 and the bus expander bridge 80 (or in the graphics expander bridge 88) and ensuring that bus activity for the new bus system is not quiesced.

Essentially, a bus is a channel or path between the components in a computer.
These slower buses connect to the system bus through a bridge, which is a part of the computer's chipset and acts as a traffic cop, integrating the data from the other buses to the system bus.

 Computer Forums - bus mastering   (Site not responding. Last check: )
As discussed in the section on system bus functions and features, bus mastering is the capability of devices on the PCI bus (other than the system chipset, of course) to take control of the bus and perform transfers directly.
The PCI bus is the first bus to popularize bus mastering; probably in part because for the first time there are operating systems and software that are really capable of taking advantage of it.
In a way, the PCI bus acts like a tiny "local area network" inside the computer, in which multiple devices can each talk to each other, sharing a communication channel that is managed by the chipset.

 Smart Bus Information
This "smart" bus was part of a joint project, undertaken by King County Metro and Sound Transit, to evaluate the next generation of on-board bus electronics and data systems.
Using a new, integrated, multi-function computer and communications system, smart buses have on-board capabilities that monitor and report on the operational and maintenance status of the bus, as well as its current location and schedule.
The new smart bus systems are expected to enable Metro and Sound Transit to improve the mechanical and schedule reliability of buses, as well as the service and information provided to riders, as they have in other U.S. cities.

After the VESA VL-bus design standard became successful and computer manufacturers had sold more than 1.4 million personal computers incorporating the VL-bus, Dell contacted certain VESA members and asserted that it obtained a patent in 1991 that they were violating by using the VL-bus standard, the complaint alleges.
In 1991-92, a VESA committee developed a standard for a computer bus design, which became known as the VESA Local Bus or "VL-bus." The bus carries information or instructions between the computer's central processing unit and peripheral devices.
For purposes of antitrust analysis, it is important to note that the complaint did not allege that Dell's representative to VESA had any knowledge of the coverage of the "481 patent or of the potential infringement by the VL-bus at the time he cast the ballot.
