3.  the first work which deserves to be
considered as the beginnings of
topology is due to Euler. In 1736
Euler published a paper on the
solution of the Königsberg bridge
problem which translates into English
as The solution of a problem relating to
the geometry of position .

4.  The configuration of a
communication network of
'Computer Science' in which the
arrangement in nodes of a LAN
is connected to each other is
known as Topology. It is a term
which defines Topology in a
simple manner.

5.  StarTopology.
 Bus Topology
 Ring/Network Topology
 Tree/Extended Star
Topology.

6.  This type Topology is often called a
multi-port repeater. In a star
topology, each device has a
dedicated point to point link only
to central controller, usually called
a hub/server/host.

9.  The bus topology is the
simplest and most
common. It is often used
when a network
installation is small,
simple, or temporary.

12.  In a ring topology, each
