Switching is a process classified as layer two of the OSI model. Switching sends data to its destination at a faster rate than routing. Switches use MAC addresses to deliver data, but switches also listen to network traffic to determine the fastest route to send data, but if no route can be found, the port will become blocked and listen only. Switches are typically only used for local destinations for a single network. Switches also broadcast data, sending the data to all available ports.

Routing is a layer higher at level 3. Routing uses IP address to determine the destination of data, and such can be done between multiple networks. Routers have protocols that determine multiple destinations for packets.
