Abstract
A bus switching structure and a computer using the same, wherein input/output (I/O) slot connections are switched to a desired I/O bus so that loads are distributed evenly over the I/O buses. The bus switching structure includes a switching unit and switching controller. The switching unit is located interposingly between an I/O slot and a plurality of I/O buses. The switching unit either connects or disconnects the I/O slot to or from each of the I/O buses in accordance with a switching signal. The switching controller outputs the switching signal to cause the switching unit to connect the I/O slot to one of the I/O buses and to disconnect the I/O slot from any of the other I/O bus, thereby effecting connection switchover between the I/O slot and the I/O buses.
