What is switching and routing in networking in networking?


Asked by Titus Hickman on Dec 08, 2021 FAQ



Switching is the movement of the packets from one device to another and the condition is that all the devices involving this process should be on the different networks. By using the Network ID presented in the Network Layer header, a router can determine where to send packets.
Next,
In packet switching networks, routing is the higher-level decision making that directs network packets from their source toward their destination through intermediate network nodes by specific packet forwarding mechanisms. Packet forwarding is the transit of network packets from one network interface to another.
In fact, The Switching function can be explained more simply that, Switching is the function of moving data packets (Ethernet Frames) within the same LAN (Local Area Network). Routers operate at Layer 3 of the OSI Model (Network layer). A Router knows where to send a packet by using Network part of the destination IP address.
Subsequently,
Network switching is the process of transmitting data packets from the source to the destination through a number of intermediate network nodes. Here, each node controls or switches data packets to the next node towards the destination. When data comes on a node it is called ingress, and when data goes out of a node it is called egress.
Moreover,
Definition of ROUTING in Network Encyclopedia. What is Routing (in computer networking)? ROUTING is the process of selecting a path through an internetwork over which to transmit packets to a destination host or hosts and then having devices called routers forward the packets to those hosts.
