Explanation
Data buses are used to transfer data between different components of a computer system. The width of a data bus determines how many bits can be transmitted simultaneously. Common data bus widths include 8, 16, 32, and 64 bits. While the question doesn't specify a definitive answer, 4 bits is a typical width for a single line of a data bus.
