What is the name of the electrical pathway used to transport data between computer components?

The correct answer is "Bus" because a bus is the electrical pathway used to connect different components of a computer, allowing data to be transmitted between them. It serves as a communication system that transfers data between the processor, memory, and other peripherals, effectively facilitating the exchange of information essential for the computer's operation.

The other options relate to different aspects of computer hardware and software but do not describe an electrical pathway for transporting data. RAM is a type of volatile memory used to store data temporarily while the computer is on, CMOS refers to a technology used for low-power, battery-backed memory that holds BIOS settings, and BIOS is the firmware that initializes and tests hardware components at startup but does not serve as a data pathway.
