Computer buses Computer buses The Accelerated Graphics Port (also called Advanced Graphics Port) is a high-speed point-to-point channel for attaching a graphics card to a computer's motherboard, primarily to assist in the acceleration of 3D computer graphics. AGP is a type of computer bus. Some motherboards have been built with multiple independent AGP slots. AGP is slowly being phased out in favour of PCI Express. ...more on Wikipedia about "Accelerated Graphics Port"
ACCESS.bus (or A.b) is a peripheral-interconnect computer bus developed by Philips in the early 1990s. It is similar in purpose to USB, in that it allows low-speed devices to be added or removed from a computer on the fly. While it was in use earlier than USB, it never became popular, largely due to considerably less corporate backing in the industry. ...more on Wikipedia about "ACCESS.bus"
An address bus is (part of) a computer bus, used by CPUs or DMA-capable units for communicating the physical addresses of computer memory elements/locations that the requesting unit wants to access (read/write). ...more on Wikipedia about "Address bus"
AHB - ie (AMBA High-performance Bus) is a bus protocol introduced in AMBA Specification version 2 published by ARM Ltd company. ...more on Wikipedia about "AHB"
The Advanced Microcontroller Bus Architecture was introduced in 1996 and is widely used as the on-chip bus for ARM processors. The first AMBA buses were ASB and APB. In its 2nd version, ARM introduced AHB that is a single clock-edge protocol. This protocol is today a de-facto standard for 32-bit embedded platforms because it is well documented and can be used without royalties. ...more on Wikipedia about "AMBA Specification"
The Horus Bus, made by Newisys for AMD, is designed to solve the inability of current motherboards to scale easily beyond 4-8 CPU's by utilizing an already developed HyperTransport system to solve interconnection issues. By putting the CPUs around the Horus chip with 12-bit lanes running at 3125 MHz with InfiniBand technology (8b/10b encoding), this system has an effective internal speed of 30 Gbit per second. For further scalability, individual Horus-based motherboards can be connected together in a network with up to 32 nodes. ...more on Wikipedia about "AMD Horus"
Apple Desktop Bus (or ADB) is an obsolete bit- serial bus for connecting low-speed devices to computers. Used primarily on the Apple Macintosh platform, ADB equipment is still available but not supported by most Apple hardware manufactured since 1998. It has been completely superseded by USB and Bluetooth. ...more on Wikipedia about "Apple Desktop Bus" Connect with http://www.shortopedia.com. shortopedia
Autoconfig is an auto-configuration feature of Amiga computers which assigns resources to expansion devices without the need for jumpers. It is analogous to PCI configuration. ...more on Wikipedia about "Autoconfig"
The back side bus is a computer bus used to connect the CPU with the L2 cache. The back side bus is found within the processor and its speed is determined by the processor. ...more on Wikipedia about "Back side bus"
A bus analyzer is a computer bus analyzation tool, often a combination of hardware and software, used during development of device drivers for a specific bus and for reverse engineering of devices by reading and interpreting bus traffic. It is essentially a logic analyzer with some additional knowledge of the underlying bus traffic characteristics. ...more on Wikipedia about "Bus analyzer"
Bus contention is an undesirable state of the bus of a computer, in which more than one memory mapped device or the CPU is attempting to place output values onto the bus at once. Normally, integrated circuits that connect to the bus are designed so that the likelihood of bus contention is nil provided that the chips are operated within their rated set-up times and so forth. However, if the bus is deliberately driven too fast, these setup times may be violated leading to contention. Contention may also arise on a system whose memory mapping is programmable, and illegal values are written to the registers controlling the mapping. ...more on Wikipedia about "Bus contention"
In computing, a bus error is generally an attempt to access memory that the computer cannot address. Bus errors can also be caused by any general device fault that the computer detects. ...more on Wikipedia about "Bus error"
Bus mastering is a feature supported by some bus architectures that enables a controller connected to the bus to communicate directly with other devices on the bus without going through the CPU. Most modern bus architectures, including PCI, support bus mastering because it significantly improves performance. ...more on Wikipedia about "Bus mastering"
In computing, a centralized storage area network (SAN) is a storage area network with many heterogenous servers connected to one single storage space. ...more on Wikipedia about "Centralized storage area networks"

Centronics Data Computer Corporation was a pioneering American manufacturer of computer printers, now remembered only for the parallel interface that bears their name. ...more on Wikipedia about "Centronics"
The Common Serial Interconnection or "CSI" is a new processor front-side bus standard being produced by Intel, as a competitor to AMD's HyperTransport. It will replace old north/south bridge for Xeon and Itanium platforms. It's expected to come out in 2008. ...more on Wikipedia about "Common Serial Interconnection"
A CompactPCI system is a 3U or 6U Eurocard based industrial computer, where all boards are connected via a passive PCI backplane. The pin assignments of the connectors are documented in standards, published by the organisation PICMG US and PICMG Europe. PICMG stands for PCI Industrial Computers Manufacturers Group. The connectors and the electrical rules allow for 8 boards in a PCI segment. Multiple segments are allowed with bridges. ...more on Wikipedia about "CompactPCI"
In computer architecture, a bus is a subsystem that transfers data or power between computer components inside a computer or between computers. Unlike a point-to-point connection, a bus can logically connect several peripherals over the same set of wires. Each bus defines its set of connectors to physically plug devices, cards or cables together. ...more on Wikipedia about "Computer bus"
A control bus is (part of) a computer bus, used by CPUs for communicating with other devices within the computer. While the address bus carries the information on which device the CPU is communicating with 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, for example if the data is being read or written to the device the appropriate line (read or write) will be active ( logic zero). ...more on Wikipedia about "Control bus"
In computing, a distributed storage area network (SAN) is a storage area network that has many geographically dispersed disk drive networks. All the networks are treated as one unit and are connected by the ISCI storage area networkprotocol ...more on Wikipedia about "Distributed storage area networks"

The Extended Industry Standard Architecture (in practice almost always shortened to EISA and frequently pronounced "eee-suh") is a bus standard for IBM compatible computers. It was announced in late 1988 by PC clone vendors (the " Gang of Nine") as a counter to IBM's use of its proprietary MicroChannel Architecture (MCA) in its PS/2 series. ...more on Wikipedia about "Extended Industry Standard Architecture"
The Feature connector was an internal connector found mostly in some older VESA Local Bus, ISA and PCI graphics cards, but also on some early AGP ones. ...more on Wikipedia about "Feature connector"
In computers, the front side bus (FSB) is a term for the physical bi-directional data bus that carries all electronic signal information between the central processing unit (CPU) and other devices within the system such as random access memory (RAM), the system BIOS, AGP video cards, PCI expansion cards, hard disks, etc. ...more on Wikipedia about "Front side bus"
Futurebus (IEEE 896) is a computer bus standard, intended to replace all local bus connections in a computer, including the CPU, memory, plug-in cards and even, to some extent, LAN links between machines. The effort started in 1979 and didn't complete until 1987, and then immediately went into a redesign that lasted until 1994. By this point everyone involved lost interest, and Futurebus saw little use. ...more on Wikipedia about "Futurebus"
