    Which of the following bus connects all the internal components of the computer with the motherboard?

    A)  Front-side bus   

    B)  External bus

    C)  Address bus      

    D)  Uniform serial bus

    Correct Answer: A

    Solution :

    [a] In computer architecture, a bus (related to the Latin "omnibus", meaning "for all") is a communication system that transfers data between components inside a computer, or between computers. This expression covers all related hardware components (wire, optical fiber, etc.) and software, including communication protocols. 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 functionality as a parallel electrical bus. Modem computer buses can use both parallel and bit serial connections, and can be wired in either a multi- drop (electrical parallel) or daisy chain topology, or connected by switched hubs, as in the case of USB.
