bd40bc7c7a USB, FireWire, and Serial ATA are examples of this. What would have formerly been a system bus is now often known as a front-side bus. Given these changes, the classical terms "system", "expansion" and "peripheral" no longer have the same connotations. Most modern systems combine both solutions, where appropriate. Gordon Bell; R. This distinction is exemplified by a telephone system with a connected modem, where the RJ11 connection and associated modulated signalling scheme is not considered a bus, and is analogous to an Ethernet connection. An early computer might use a hand-wired CPU of vacuum tubes, a magnetic drum for main memory, and a punch tape and printer for reading and writing data. This emphasizes the busbar origins of bus architecture as supplying switched or distributed power. Anecdotally termed the "digit trunk", they were named after electrical power buses, or busbars. Multidrop connections do not work well for fast serial buses, so most modern serial buses use daisy-chain or hub designs.
Early computer buses were parallel electrical wires with multiple connections, but the term is now used for any physical arrangement that provides the same logical function as a parallel electrical bus. 2014-05-29. First generation. An increasing number of external devices started employing their own bus systems as well. This led to much better "real world" performance, but also required the cards to be much more complex. They also tend to be very flexible in terms of their physical connections, allowing them to be used both as internal buses, as well as connecting different machines together. While acceptable in embedded systems, this problem was not tolerated for long in general-purpose, user-expandable computers. A microprocessor conventionally is a single chip which has a number of electrical connections on its pins that can be used to select an "address" in the main memory and another set of pins to read and write the data stored at that location. Devices on the bus could talk to each other with no CPU intervention.
