Differentiating Routers and Switches

As for switches, it's main function is to only connect networking segments to create communication between nodes through computer gateways like the Ethernet. Switches commonly processes data at the OSI layer 2 or the data link layer. Since Switches typically transfers data from interconnected nodes in a networked area. Switches is a Point-to-Point or Point-to-Multipoint data transfer and a PPP or Point to Point Protocol.

While Routers are the kind of Active networking Component that connects multiple extended networks together. It sends packets of data from multiple sources and sends it to addressed destinations.

That is Routers belongs to the Layer of the OSI Layer (Networking Layer). It transfers length of data from point-to-destination via one or more networks with quality service required by the transport layer.

In Conclusion, as what I've understood--Switches are for LAN purposes or distribution for internet connection since it is only concerned with the Layer 2 of the OSI model which is the Data Link Layer or transferring of data.
And Routers are more to network-to-network (WAN or MAN) connectivity rather than LAN.
