What is a router
´ Router is a layer 3 device which works on network layer of OSI
model which connects two different networks and it identifies network devices
based on their IP addresses.
´ The Routers are the devices used for connecting local network to
the other local network/s.
´ They are generally located at the gateway where two or more than
two networks connect.
What is a switch
´ Switch is a layer 2 device which works on data link layer of OSI
model, it communicates by using frames and it identifies network devices on the
bases of MAC addresses or physical addresses.
Router:
- Mode
of transmission:
´ It Transmits data in the form of packets.
2. Address:
It makes use of IP address for the purpose of data transmission.
3.Layer of OSI Model:
It makes use of layer 3 of OSI model.
4.Ports
Routers contain 2 Ports by default like fast Ethernet Ports.
However, we can add serial ports explicitly.
5.Table:
It makes use of the Routing Table for routes to get to the
destination IP.
