In PCs, arcade side-the front of a bus data that carries data between the CPU and Northbridge. Depending on the processor used in the system, some crossings may be an arcade side-rear also have that processor to cache communication.
bandwidth or the maximum admission capacity of the passageway-side-up to the length of the data, the frequency of the clock(Clock), and the number of data in each cycle is sent, depends.For example, a bandwidth of 64-bit processor, at frequency of 100MHz, four of which data in each cycle sends a bandwidth equivalent of 3200MB per second(MB/s)
