Buses are just conductors to carry data from one place to another place in terms of microprocessor from one register to another register.

the bus through which the data are transmitted or received within microprocessor and with peripherals is called as data bus.when used internally to microprocessor called internal data bus.
Internal data bus is defined as a collection or a sequence of the signal line that are responsible for carrying data from one computer to another computer or from one destination to another destination. Basically it is used to transfer data to the external drives and also referred as the internal bus.
Internal Bus
A data bus connects different parts of a circuit and comprises a group of parallel wires, each one carrying a different logic signal.
The contents of the stack pointer and program counter are loaded into the address buffer and address-data buffer. These buffers are then used to drive the external address bus and address-data bus. As the memory and I/O chips are connected to these buses, the CPU can exchange desired data to the memory and I/O chips. The address-data buffer is not only connected to the external data bus but also to the internal data bus which consists of 8-bits. The address data buffer can both send and receive data from internal data bus.
Which processor has a 32-bit Data Bus and a 24-bit Address Bus?
the internal data path the address bus the clock speed the cache

The 8086/8088 has an internal 20-bit address bus and 16-bit data bus. Externally, the address bus is 20-bits, and the data bus is 16-bits for the 8086 and 8-bits for the 8088.The data bus in the 8086 is 16 bits in size, while the address bus is 20.
In computers, the bus is the subsystem that transfers data between internal parts of the computer, or from internal parts of the computer to external parts, or between two computers. External bus can be parallel (ATA (and all of its derivations), IEEE-488, SCSI) or serial (USB, FireWire, etc.).
Essentially, any peripheral or component of a computer has a bus. These are either internal or external in nature. The address bus, data bus, and local bus is the system by which components communicate with one another.
