This document discusses different types of computer networks and networking devices. It describes Local Area Networks (LANs) which connect devices over short distances, like within an office or home, Metropolitan Area Networks (MANs) which connect devices within a campus or city, and Wide Area Networks (WANs) which connect devices over long distances, like across countries. It also outlines common networking devices like hubs, switches, and routers that are used to connect and direct data between computers in networks.

4. A networked office building,
school, or home usually
contains a single LAN.
LAN
Connects network devices
over a relatively short
distance.

5. WAN
ROUTER devices is used in
WAN.
A large geographic area such
as country, continent or even
whole of the world.

6. Larger than LAN but
smaller than WAN.
They are used to
create communication
between systems in an
MAN

7. CAN
Different buildings in a campus Can
be
Made up of two or more LANs with
in limited area.
All the computers connected
together have some relationship to
each other

8. NETWORKING DEVICES
There are
several devices
used in a
computer:
E.G. Hub,

9. Used to connect
computers in a
networks.Hub has sockets on it,
each socket can have
one connector.Data sent from any One
computer comes to all

10. May be manageable or
non-manageable.
Used to inter-connect
the network.
Available in 8 ports, 16
ports, 24 ports.

11. Router is used to
direct data between
two networks.
It read information to
attached data, to find
Connect public
network or private
network.
