first of all the differnce between layer2 and layer3 switching:
layer 2 is for peer to peer communication
layer 3 is for process to process communication
A Layer3 switch u can say an enhanced switch with some
routing capabilities
Broadly we can say switch is a devive using hardware to
create network paths whereas a router does same by
CPU's(s/w). As sudeep above mentioned that layer3 switches
use ASIC chips/circuit over microprocessor in routers it
results into Faster speed(min latancy)
The L3 switches are best suited for Lan & routers for
WAN(for optimised performance rather u can use both in any role)
