NETWORK TOPOLOGY
A network topology refers to the
layout of the computers and devices
in a communication network.
NETWORK TOPOLOGY
The three basic network topologies are
star, bus and ring. Most networks,
including the internet, use the
combinations of these basic
topologies.
STAR TOPOLOGY
All the computers and
devices on a star
network connects to a
central device. This
central device may be a
hub or a switch.
• Any devices or computers
connected to a network is
called a node.
• All the data that has been
transmitted from one
node will pass through the
central device before
reaching the other node.
• Nodes can be added or
removed from the
network with little or no
disruption to the entire
network.
• Star network are fairly
easy to install and
maintain.
What will happen if a node
or the central device fails
on a star network?
If one node fails, only
that node is affected.
The other nodes continue
to operate normally.
However, if the central
device fails, the entire
network is inoperable
until the device is
repaired.
BUS TOPOLOGY
The bus has a single
central cable (physical
cable) to which all
computers and other
devices connected.
• It transmits data, instructions and
information in both directions.
• Bus network are cheap and easy to
install.
• Computers and devices can be
attached or detached at any point on
the bus.
• Failure of one device usually does not
affect the rest of the bus network.

• What
RING TOPOLOGY
On a ring network, a
cable forms a closed
loop (ring) with all
computers and devices.
• Data is being
transmitted from one
device to other around
the entire ring in one
direction.
• If one computer on a
ring network fails, the
entire network could
stop functioning.
DIRECTION: Read each statement
below carefully. Write T if the
statement is true. Supply the
correct word for the underlined
word if the statement is false. Use
the group of words below for your
answer.
1. Network is a collection of
computers and devices connected
together so that they can exchange
information or share resources.
2. A data package is a unit of data made
into a single package that travels along a
given network path. Data package are
used in Internet Protocol (IP)
transmissions for data that navigates the
Web, and in other kinds of networks.
_________3. The three basic network
topologies are star, mesh and ring.
_________4. All of the computers and
devices on a bus network connects to
a central device. This central device
may be a hub or a switch.
5. If one node fails in a star network,
only that node is affected. The other
nodes continue to operate normally.
