Optical discs are read using lasers to read data from a reflective surface of a laser that can be scattered or reflected, and a common disc is a DVD. Many systems say they are 32-bit or 64-bit, which refers to the number of bits in a register, address bus, or data bus. For example, on a 64-bit motherboard, the data bus (silver wire between components) has 64 lines that are side-by-end. Memory addresses are addressed in memory in the form of bit
