2. What is topology
The topology of a network defines how the node of a
network are connected
Two basic categories
1.Physical topology
2.Logical topology
3. Physical topology:
Defines how the nodes of the network are
physically connected .
Logical topology:
How data is transmitted between nodes
4. Different types of network topologies
Mesh
Star
Bus
Ring
Tree and Hybrid
5. Mesh Topology
• A network setup where each computer and
network device is interconnected with one
another,
• Allowing for most transmissions to be
distributed, even if one of the connections go
down
6. Bus topology
Bus topology is a network setup in which
each computer and network device are
connected to a single cable or backbone.
7. Star topology
A star topology is a topology for a Local Area
Network (LAN)
In which all nodes are individually connected
to a central connection point, like a hub or a
switch.
8. Tree topology
A tree topology combines characteristics of
linear bus and star topologies.
It consists of groups of star-configured
workstations connected to a linear bus
backbone cable
9. Ring topology
A ring topology is a network
configuration in which device
connections create a circular data path
Each networked device is connected to
two others, like points on a circle.
Together, devices in a ring topology are
referred to as a ring network.
