Bus

The Bus is a roadway, circuit, on which electronic impulses travel throughout the computer. It is called a bus because "loads" or "bits" of data from one component to the main board is transferred to another component. After the load is dropped off the bus picks up another load and drops it off. The bus carries data lines, signals that represent data, and address lines which tell the location of the data on the computer. The larger the bus width the more is the information that can flow. It is measured in bits. The higher the bus speed the faster the data goes. Bus speed is measured in megahertz (MHz), millions of cycles per second.
