A bus system is a method used in computer architecture to transfer data between different components, such as the CPU, memory, and input/output devices. It acts like a highway for data, allowing multiple parts of the computer to communicate efficiently. The bus can carry various types of information, including instructions and data, and it helps ensure that everything works together smoothly. In addition to computer systems, bus systems are also common in public transportation. They provide a way for people to travel within cities, connecting neighborhoods and key locations. These public buses follow specific routes and schedules, making it easier for commuters to reach their destinations without needing a car.
