The specific computer architecture or system can affect the width of the address and data buses. The central processing unit (CPU), memory, and input/output devices can all communicate with one another more easily thanks to these vital components of a computer's design.
Varying computer architectures may have varying bus widths, and even within a single design, different models may have distinct bus widths. To find out the precise width of a processor or computer system, always consult the technical literature or specifications. This includes the data and address buses.
Data Bus
Data must be transported via the data bus between the CPU and additional parts like peripheral devices and memory. 8-bit, 16-bit, 32-bit, 64-bit, and even bigger configurations are examples of common data bus widths.
Address Bus
To provide a memory address—the location from which data should be read or written—use the address bus. The maximum addressable memory is determined by the address bus width. A 32-bit address bus, for instance, can address 2^32, or around 4 billion, distinct memory locations. In many computer architectures, the address bus widths match the data bus widths.
