What is Routing and Switching?
Computer networking’s fundamental operations are switching and routing. Locating a path between multiple networks is known as routing, and transferring data from one device to another inside a network is known as switching.
The foundation of all communications, including data, phone, video, and wireless access, comprises these two ideas. Companies and organizations use routing and switching to facilitate remote connections, share applications, enhance customer service, expedite information access, save operational costs, and strengthen security.
Devices called routers are used to link networks together. Routing protocols involve specialized algorithms that aid routers in figuring out the most efficient way to transfer data across networks. The Open Shortest Path First, or OSPF, etiquette or protocol and the Border Gateway Protocol (BGP) are examples of standard routing protocols.
Devices that link devices in a network are called switches. Switching is the process of forwarding data between devices via switching. Media Access Control (MAC) addresses are used by switches to identify the location of data entry and transmit it appropriately.
