What are the many fine lines on the top and bottom of a motherboard's surface? What is the purpose of these lines?
What will be an ideal response?
These lines, sometimes called traces, are circuits or paths that enable data, instructions, and power to move from component to component on the board. This system of pathways used for communication and the protocol and methods used for transmission are collectively called the bus. The parts of the bus that we are most familiar with are the lines of the bus that are used for data; these lines are called the data bus. A bus can also carry electrical power (to power components on the motherboard), control signals (to coordinate activity), and memory addresses (for one program to tell another program where to find data or instructions).
