A NETWORK IS A SET OF DEVICE
CONNECTED BY COMMUNICATION LINKS.
THERE ARE TWO TYPES OF NETWORK:
 PEER- TO - PEER NETWORK
 CLIENT/SERVER NETWORK

5. Types of Network Devices

6. Router
o It is Device that interconnects two or
more computer networks
oIt works like a bridge but can handle diff.
protocols

7. Easily Shared Internet
Router can function on LAN & WAN.
DISADVANTAGES
Its expensive than Hub, Bridge & Switch.
 Speed

8. 


Easy Setup
Firewall
Additional Security
Number of Connection Ports

9. Internet

10. Introduction
 It is a small hardware device that joins
multiple computers together within one local
area network (LAN).
It is used to send and receive the data over
the LAN and WAN.
A switch comes in different ports like 6, 8,
16, 24 and uplink ports,

11. ADVANTAGES
Packet Handling of Network Switches
Bandwidth Utilisation of Network
Switches
Problem Isolation of Network Switches

12. DISADVANTAGES
Its difficult to install
proper designing and configuration is
required if multicast packets are being handled
At times swtiches when in Promiscuos mode
is a opening for Security attacks [Spoofing ip
address or capturing Ethernet Frames using
ethereal]

13. FEATURES
Speed
Port Density
Forwarding Rates

15. Introduction
A bridge is a network communication device that is used
to connect one segment of the network with another that
uses the same protocol.
 It operates at the Data link layer of the OSI layers
model.
In the Ethernet network, the bridge is also known as IEEE
802.1D.
A bridge process the information at the data link layer of
the OSI layers model.
Connecting two networks together across a single
computer is called bridging networks.

16. ADVANTAGES
It's cheap, easy, doesn't require routing to
work.
It’s simple to use
It’s help to lower the data load over the data
link layer.

17. DISADVANTAGES
Bridges are unable to read specific IP
address.
Speed of it is low.
Can not use firewall as a device.
Messages are sent to all the nodes.
More Expensive than repeaters.

18. FEATURES
Routing
Filtering
Forwarding
Learning algorithm
