Network topology And Its type
1.
2. Physical topology refers to the placement
of the network's various components,
including device location and cable
installation, while logical topology shows
how data flows within a network,
regardless of its physical design
4. A linear bus topology consists of a main
run of cable with a terminator at each end.
All servers workstations and peripherals
are connected to the linear cable
5. Advantages –
Easy to install and use.
Cables are less used then star or ring
topology.
Disadvantages-
Disorder in any node may lead to failure of
entire data transmission.
It is difficult to add a new node to the
structure.
6.
7. A star network is designed with each
node (file server, workstation, peripheral)
connected directly to a central network
hub or server.
8. Advantages –
An advantage of the star topology is the
simplicity of adding additional nodes.
Good option for modern networks
Low startup costs
Easy to manage
Disadvantages-
Hub is a single point of failure
Requires more cable than the bus
9.
10. A ring network is one where all
workstations and other devices are
connected in a continuous loop. There is
no central server. A network topology that
is set up in a circular fashion in which
data travels around the ring in one
direction and each device on the ring acts
as a repeater to keep the signal strong as
it travels
11. Advantages-
Easier to manage; easier to locate a defective
node or cable problem
Handles high-volume network traffic
Enables reliable communication
Disadvantage-
Expensive
Requires more cable and network equipment at
the start
12.
13. This particular type of network topology is
based on a hierarchy of nodes. The highest
level of any tree network consists of a single,
'root' node, this node connected either a
single (or, more commonly, multiple) node(s)
in the level below by (a) point-to-point link(s)
14. Advantages –
It is scalable. Secondary nodes allow more
devices to be connected to a central node.
Point to point connection of devices.
Having different levels of the network makes it
more manageable hence easier fault
identification and isolation.
Disadvantages-
Maintenance of the network may be an issue
when the network spans a great area.
Since it is a variation of bus topology, if the
backbone fails, the entire network is crippled.
15.
16. It is also known as graph topology. In this topology each
node is connected in another node “Directly". So there is a
mesh in the network as there are so many wires that are
connected to each and every node.
Fully Connected- A fully connected network is a
communication network in which each of the nodes is
connected to each other. A fully connected network doesn't
need to use switching nor broadcasting.
Partially Connected- The type of network topology in
which some of the nodes of the network are connected to
more than one other node in the network with a point-to-
point link.
