Routing and Switching are essential functions in computer networks that help direct data traffic. Routing involves determining the best path for data to travel across multiple networks, using devices called routers. These routers analyze the destination address of data packets and forward them accordingly, ensuring efficient communication between different networks. On the other hand, Switching occurs within a single network, where switches connect devices like computers and printers. Switches receive incoming data packets and send them to the correct device on the local network, allowing for quick and efficient data transfer. Together, routing and switching enable seamless connectivity in modern communication systems.
