3. Introduction to NETWORK SWITCH
 A network switch is a device used to
connect network segments or network
devices.
 Network switch receive messages and send
them to the targeted audience.
 It is a telecommunication device that uses
the packet switching to receive , process and
forward data to the destination address

5. CONTD…..
Network switch forwards data to one
or multiple devices that need to
receive it.
Switches are the multiport network
bridges that process and forward data
at the data link layer(layer 2 of OSI
model).

6. Network with a Switch

7. APPLICATIONS OF SWITCHES
 A switch is a device used in a computer
network to physically connect the devices
together.
 A switch can transfer data to any of the other
devices at a time using half duplex mode or
full duplex mode.
 A switch can manage the flow of data across
the network.

8. Contd…
A network switch plays an integral part in
most modern Ethernet LANs. Mid to large
sized LANs contain a number of linked
managed switches
Each network device is connected to a
switch is identified using a MAC address
or a hardware address. There fore, a
switch is also considered as a intelligent
network hub.

9. Switch vs hub

10. What
happened when hub received a message ?

12. What happened when switch received a
message ?

15. Switch vs Router

18. ADVANTAGES
 The number of broadcast domains gets
decreased.
 Unlike hub, switches are more hardware
oriented.
 It can make use of CAM table for port to MAC
mapping.
 Unlike router , multi ports of switches are
available in lower cost.
 It helps in logical segmentation by supporting
VLAN.

19. DISADVANTAGE
 Proper designing and configuration is
required if multicast packets are being
handled.
 While limiting broadcasts, switches
are not as good as routers.
