Routers:
Routers are the connecting devices in networking. it is used to choose the smallest path for a packet to attain its destination. Its main objective is to attach varied networks at the same time and it works in the network layer.
Layer-3 Switches:
Layer-3 Switches were formed as a technology to boost on the performance of routers utilized in massive native space networks (LANs) like company intranets. The key distinction between Layer-3 switches and routers lies within the hardware technology accustomed build the unit. The hardware within a Layer-3 switch merges that of ancient switches and routers, exchange a number of a router’s software package logic with hardware to supply higher performance in some things. Layer-3 switches typically value but ancient routers. Designed to be used among native networks, a Layer-3 switch can usually not possess the WAN ports and wide space network options a conventional router can perpetually have.
Difference between Router and Layer-3 Switch:
