This document summarizes different types of computer networks including local area networks (LAN), metropolitan area networks (MAN), and wide area networks (WAN). It also describes client-server and peer-to-peer network architectures, as well as common network topologies like bus, ring, and star. Additionally, it outlines different network communication technologies such as intranet, extranet, and internet. The document was created by Sehajbir Singh of Class VIII-E to provide an overview of computer network types, architectures, topologies, and communication technologies.

3. TYPES OF COMPUTER NETWORK
. Local Area Network (LAN)
2. Metropolitan Area Network (MAN)
3. Wide Area Network (WAN)

7. TYPES OF NETWORK A

8. CLIENT – SERVER NETWORK ARCHITECTURE
It is a type of network
where
different computers called
CLIENTS are connected to
a
main computer called
SERVER.
CLIENT
SERVER

9. PEER - TO - PEER NETWORK ARCHITECTURE
In this type of network
architecture
different computers having
equal capacities
are connected together to use
resources available on the
network .

10. Types of
Network
Topologies

11. • This type of network was widely used in
the 1980’s
• In this configuration every computer
(node) shares the networks total bus
capacities.
• In this configuration adding more
computers will reduce the access speed
on the network.

12. • In Ring topology each node is connected to the two
nearest nodes so the entire network forms a circle
• Data only travels in one direction on a Ring network

13. • In a Star topology every node is connected
through a central device such as a Hub, Switch
or Router
• Compared to a Ring or Bus topology a Star
topology requires that more thought be put
into its setup
HUB

14. NETWORK COMMUNICATION
TECHNOLOGIES
1. INTRANET
2.EXTRANET
3. INTERNET
