1. Network Topology

2. Network Topology
Network topology refers to the manner in which
the links and nodes of a network are arranged
to relate to each other. Physical network
topology examples include star, mesh, tree,
ring, point-to-point, circular, hybrid, and bus
topology networks, each consisting of different
configurations of nodes and links.

Topolgy

4. 1. Point to point topology
Point to Point topology is the simplest
topology that connects two nodes directly
together with a common link. The
point-to-point connections use an actual
length of wire or cable to connect the two
ends, but other options, such as satellite
links, or microwaves are also possible.

6. 2. Bus topology
Bus topology, also known as line topology, is
a type of network topology in which all
devices in the network are connected by one.

7. 3. Ring topology
A ring network is a network topology in which
each node connects to exactly two other nodes,
forming a single continuous pathway for signals
through each node – a ring. Data travels from
node to node, with each node along the way
handling every packet.

9. 4. Star topology
A star network is an implementation of a
spoke–hub distribution paradigm in computer
networks. In a star network, every host is
connected to a central hub. In its simplest
form, one central hub acts as a conduit to
transmit messages. The star network is one of
the most common computer network
topologies.

11. 5. Tree topology
A tree topology, or star-bus topology, is a
hybrid network topology in which star
networks are interconnected via bus
networks.

12. Tree topology

13. 6. Mesh topology
A mesh network is a local network topology
in which the infrastructure nodes connect
directly, dynamically and non-hierarchically
to as many other nodes as possible and
cooperate with one another to efficiently
route data from/to clients.

15. 7. Hybrid topology
A hybrid network topology is an
interconnection of two or more basic network
topologies, each of which contains its own
nodes. The resulting topology will exhibit
characteristics of all the constituent
topologies, thereby limiting the inherent
weaknesses of each topology.

17. Straight and
Crossover Cable

18. Straight Cable
A straight through cable is a type of twisted
pair cable that is used in local area networks
to connect a computer to a network hub such
as a router.

19. Straight Cable

20. Crossover Cable
A crossover cable is a type of cable
installation that is used for the
interconnection of two similar devices. It is
enabled by reversing the transmission and
receiving pins at both ends, so that output
from one computer becomes input to the
other, and vice versa.
