1. Understanding the unique roles of LAN, MAN and
WAN

2. Network
 Collection of inter connected nodes or devices
 Enables communication and resource sharing among
connected devices
 Categorized based on geographical scope(LAN, WAN,
global)
 Components include nodes, links, protocols, and
topology.
 Facilitates the exchange of data and information
among connected devices.

3. Types of networks
 Local area network (LAN)
 Wide area network (WAN)
 Wireless networks
 Metropolitan area network (MAN)
 Internet
 Intranet
 Extranet
 Virtual private network (VPN)
 Client-server-network
 Peer-to-peer network (P2P)

4.  Covers a small region of space, typically a single
building
 LAN is the small network.
 the simplest form of LAN is to connect two computers
together
 LAN is operated within a limited physical area such as
at home, school, a single building or several buildings.
 A network which consists of less than 500
interconnected devices across several buildings, is still
recognised as a LAN.
Local Area Network (LAN)

5.  LAN is very high speed network (from previously
10Mbps) to 100Mbps,which is faster than MAN and WAN.

6. Metropolitan Area Network(MAN)
 Is collection of LANs with the same geographical area, for
instance a city.
 Is a network of computers located at different sites within a
large physical area, such as a city.
 MAN often acts as a high speed network(although not as
fast as LAN) to allow sharing of regional resources.
 MAN can defined as a group of computers and network
devices connected together within a large physical area.
 Companies that have several branches within the Kuala
lumpur city such as banks, might find a MAN useful to
them.

9. Wide Area Network (WAN)
 Is the largest network of all network types.
 The internet is the largest WAN in the world.
 WAN generally covers large distances such as states,
countries or continents.
 WAN is group of MANs or LANs or the mixture of both
network.
 An example in the society using WAN is the banking
organization.
