Data flows between different parts of the computer via

• A. Ports
• B. Buses
• C. Cables
• D. Networks

Answer: (B)

Data moves inside a computer through shared pathways called buses. These buses connect the main components—the CPU, memory, and input/output devices—so data, addresses, and control signals can be sent where needed. Different buses handle different roles: the data bus carries the actual information, the address bus specifies where that data should go, and the control bus manages timing and coordination.

Ports are entry points for external devices, cables are the physical links that connect devices, and networks connect multiple computers. While they serve important roles in systems, the internal data transfer between parts of the computer happens primarily over buses.
