Network topology And Its type in detail If you liked it don't forget to follow me- SlideShare-www.slideshare.net/gauravyadav65 Instagram-yadavgaurav251 Facebook-www.facebook.com/yadavgaurav251 This really motivates me too help you guys more :D

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

3. Bus Topology
Star Topology
Ring Topology
Tree Topology
Mesh Topology

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.

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

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

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.

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.

18.  Physical topology have _____ no. of
topologies?
 (a)Five (b)Two
 Ans. (a)Five
 In case of failure of one node in ring topology
the whole system crashes
 (a)True (b)False
 Ans. (b)False
 If hub fails then whole network fails.
 a)True (b)False
 Ans. (a)True

19.  Mesh topology is of _______ types.
 (a)three (b)two
 Ans. (b)two
 Bus topology is _____________
 (a)Expensive (b)cheap
 Ans. (b)Cheap
 _______ topology require more cable than
Bus topology
 (a)Star (b)Ring
 Ans. (a)Star

20.  In ______topology each node is connected to
a single cable?
 (a)Bus (b)Ring
 Ans.(a)Bus
 Token passing is used in ________ topology?
 (a)Star (b)Ring
 Ans.(b)Ring
 Topology is divide in _____ types in accordance
with the transmission method
 (a)three (b)two
 Ans. (b)two
