What is the difference between switching and routing about Three pages
Switching and routing are both integral components of computer networking, but they serve slightly different functions.
Switching involves directing data within a network from one device to another. In a switch, data packets are forwarded based on the device's MAC address. Switching occurs at the data link layer (Layer 2) of the OSI model. Switches store MAC addresses in a table and use this information to forward data to the correct destination. Switches are typically used in Local Area Networks (LANs) to improve network efficiency and reduce network congestion.
Routing, on the other hand, involves directing data between different networks. Routers forward data packets based on the destination IP address. Routing occurs at the network layer (Layer 3) of the OSI model. Routers maintain routing tables that contain information about the best path to reach a destination network. Routers are used to connect multiple networks together and determine the best path for data to travel between them.
In summary, switching is concerned with directing data within a single network based on MAC addresses, while routing is concerned with directing data between different networks based on IP addresses. Switches are used to connect devices within a network, while routers are used to connect multiple networks together. Both switching and routing are essential for ensuring that data is delivered efficiently and accurately within a network.
