What is System Bus? Explain a few related terms.

System Bus are parallel electrical paths that transport data between the CPU and Memory. - Bus Width: The number of electrical paths that to carry the data. It is measured in Bits. With larger Bus Widths, a CPU can transfer more data at a time.

- Bus Speed: The speed of the bus is measured in megahertz (MHz), refers to how much data can move across the bus simultaneously. Personal computers have a bus speeds of 400 MHz or 533 MHz.
