| | Data Bus |
 | | The bus is the pathway -- on the motherboard and beyond -- that allows data to flow from one part of your computer system to another. | | | In the same way, information moving between computer components on the data bus can only occur if a common protocol is used. | | | EISA was developed to counter the development of an improved, proprietary data bus designed by IBM. |

| | Information about the computer BUS |
| | A computer bus is a method of transmitting data from one part of the computer to another part of the computer. | | | One of the major downfalls of the MCA bus was it being a proprietary bus and because of competing bus designs. | | | When this bus was originally released it was a proprietary bus, which allowed only IBM to create peripherals and the actual interface. |

| | Front side bus - Wikipedia, the free encyclopedia |
| | The frontside bus has been a part of computer architecture since applications first started using more memory than a CPU (a very complex integrated circuit) could reasonably hold. | | | Front Side Bus (FSB) is the term used to describe the CPU data bus. | | | This is listed because it is the only bus that allows communication between the processor and the rest of the system, which was traditionally one of the functions of the frontside bus. |

| | TechFest - PCI Local Bus Technical Summary |
| | Typical TTL devices used in previous bus implementations such as ISA and EISA are not compliant with the requirements of PCI. | | | It architects a means of supporting a 64-bit data bus through a longer connector slot, but most of today's personal computers support only 32-bit data transfers through the base 32-bit PCI connector. | | | The ISA bus has initially continued to co-exist with PCI for support of "legacy" add-in boards that don't require the high performance of the PCI bus. |

| | Enhanced 64-Bit Data Bus |
| | The data bus is the highway that carries information between the processor and the memory subsystem. | | | This wider data bus facilitates high-speed processing by maintaining the flow of instructions and data to the processor's superscalar execution unit. | | | Write buffers improve performance by allowing the processor to proceed with the next pair of instructions, even though one of the current instructions needs to write to memory while the bus is busy. |

| | Matching Data Bus Throughput To Data Acquisition Needs |
| | The ISA bus was well matched to the world of 8- and 16-bit computing, but when the 32-bit chips came along, ISA became just another way to spell bottleneck. | | | Yet in high-speed data acquisition applications, the method of data transfer between the data acquisition board and computer memory or the monitor is just as important as the speed of the ADC or DAC. | | | The PCI bus eliminated the bottleneck of the ISA bus. |

| | The Data Bus/Address Bus |
| | The data bus is also a collection of wires but this carries instructions and data, not memory addresses. | | | The electrical bus inside the computer is the channel around which addresses and data travel. | | | The "bus" inside a computer is similar to a bus which carries passengers around a city. |

| | Fast Accurate Memory Test Suite - RAM, SRAM, DRAM, address bus, data bus |
| | We need to confirm that any value placed on the data bus by the processor is correctly received by the memory device at the other end. | | | There are many other possible choices of data, but the incrementing data pattern is adequate and easy to compute. | | | If the data values are unique (as they are in the test just described), the missing chip will be detected: the first value read back will correspond to the last value written (3), rather than the first (1). |
