<div style="text-align: left;">
 Routers are networking devices that forward data packets between networks using headers and forwarding tables to determine the best path to forward the packets.</div>
<div style="text-align: left;">
Routers work at the network layer of the TCP/IP model or layer 3 of the OSI model. </div>

<b> ♦ Switch and Hubs ♦</b></div>
<div style="text-align: left;">
A network switch is a small hardware device that joins multiple computers together within one local area network (LAN). A switch normally has numerous ports, with the intention being that most or all of the network is connected directly to the switch, or another switch that is in turn connected to a switch.</div>

<div style="text-align: left;">
Network switches appear nearly identical to network hubs, but a switch generally contains more intelligence (and a slightly higher price tag) than a hub. Unlike hubs, network switches are capable of inspecting data packets as they are received, determining the source and destination device of each packet, and forwarding them appropriately. By delivering messages only to the connected device intended, a network switch conserves network bandwidth and offers generally better performance than a hub.</div>
