What do u mean by term bus,single bus architecture,future bus and PCI?
bus is a subsystem that transfers data 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. The bus analyzer monitors the bus traffic and decodes and displays the data. It is essentially a logic analyzer with some additional knowledge of the underlying bus traffic characteristics. 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. Peripheral Component Interconnect, or PCI Standard (commonly PCI), specifies a computer bus for attaching peripheral devices to a computer motherboard.
