Please do parphsing for these parpharphs please because it is 69% palagrisim percentage, see the parpharphs below . 1)Data bus : It is a group of conducting wires which carries Data only. Data moving in and out of the data bus is bi-directional, since the processor reads and writes data .When it is write operation, the processor will put the data (to be written) on the data bus, when it is read operation, the memory controller will get the data from specific memory block and put it into the data bus. The width of the data bus reflects the maximum amount of data that can be processed and delivered at one time.A 64-bit processor has a 64-bit data bus and can communicate 64-bits of data at a time ◆◆Address bus and control bus are◆◆ uni-directional 2)Address bus : It is a group of conducting wires which carries address only. Address bus is unidirectional because data flow in one direction, from microprocessor to memory or from microprocessor to Input/output devices. 3)Control bus :…
