the system bus can be divided into three major parts i.e, address bus, a control bus, and data bus. The major difference between Address Bus, Control Bus, and Data Bus is that address bus identifies the source or destination of data, data bus used to carry data signals while the control bus controls the signals among devices.
|It is the connections between CPU and main memory.||It is the physical connection between CPU and other devices with the computer.||It is a communication route through which data can travel between the computer’s CPU, memory, and peripherals.|
|It is used to identify particular locations in main memory where data is stored.||It carriers control information between the CPU and other devices within the computer.||Data can travel through the data bus between the computer’s CPU, memory, and peripherals.|
|The number of bits in the address bus can determine the amount of memory, the CPU can address.in modern PCs, there are 36 address lines to access the 64 GB of main memory theoretically.||One line of the bus is used to indicate whether the CPU is currently reading from or writing to main memory.||The number of wires determines the speed of data traveling. Each wire transmits a single bit at a time. So 8 bits bus can transfer 8 bits at a time.|
