The layout pattern of the interconnections between computers in a network is called network topology. ... Network topology is illustrated by showing these nodes and their connections using cables. There are a number of different types of network topologies, including point-to-point, bus, star, ring, mesh, tree and hybrid.
Computer Network Topology By Team_ Paramount (Dept. English)Suman Mia
A network topology is the physical and logical arrangement of nodes and connections in a network.
Nodes usually include devices such as switches, routers and software with switch and router features. Network topologies are often represented as a graph.
Types of network topology, hub, switch, router, repeater and brouterAlidHasan4
Geometric representation of how the computers are connected to each other is known as topology. There are five types of topology – Mesh, Star, Bus, Ring and Hybrid.

Strategies for Effective Upskilling is a presentation by Chinwendu Peace in a Your Skill Boost Masterclass organisation by the Excellence Foundation for South Sudan on 08th and 09th June 2024 from 1 PM to 3 PM on each day.
A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

This topic is to be covered in one week. The mode of
instruction is through presentations online. The mode of
assessment is through CATs and class practical and a full
sitting Examinations.Others resources like journals are
also provided, that include journals and other textbooks
are listed.
2. The term network Topology refers to the way in which
computers, cables, and other devices have been arranged
in the network.
It can also refer to how data is passed from one computer
to another in the network.
Logical and physical topologies
Network topology can be viewed in 2 ways; Logical or
Physical.
Logical (Signal) topology
Logical topology deals with the way data passes from one
device to the next on the network.
Examples of logical topologies are:
(a). Ethernet.
(b). Token ring.
3. Ethernet topology
In Ethernet topology, all computers listen to the network
media, and a particular computer can only send data
when none of the others is sending.
Token ring topology
In Token ring topology, a special package for data called a
token goes around the network. The computer whose
address is on the data held in the token picks it up, reads
the data, and then releases the token. The token can
then be captured by another computer which needs to
transmit data.
4. Physical topology
Physical topology refers to the physical arrangement of
components on the network.
Examples of physical topologies are:
(a). Star topology.
(b). Bus topology.
(c). Ring topology.
(d). Mesh topology.
(e). Tree (Hierarchical) topology.
The choice of the topology to adopt depends on factors
such as Reliability, Expandability, and Performance.
5. Star topology
Star topology consists of computers and other devices,
each connected to a common central server called the
Hub. However, to connect to the central machine, each
computer uses a separate cable.
Nodes communicate across the network by passing data
signals through the hub, i.e., any two computers
(workstations) in the network communicate through the
central machine.
When the hub receives data from a transmitting computer,
it broadcasts the message to all the other nodes on the
network.
6.
7. Advantages of Star topology.
1. Allows key networking resources such as concentrators & servers to be centralized.
2. Easy to configure.
3. Enhances operational survivability.
The hub isolates the network cables from each other. Even if a wire between a workstation
and the hub breaks or develops a bad connection, the rest of the network remains
operational.
1. Simple to control.
2. It can be extended easily, since a workstation is simply connected to the hub.
3. Provides flexibility in adding or deleting devices.
The wiring hubs increase the flexibility for growth. Addition & removal of nodes does not
involve cutting and joining of cables.
1. Easier to troubleshoot.
When something goes wrong with the network, the administrator can troubleshoot it from
the wiring hub.
1. The Hub can support multiple types of cables.
Disadvantages of Star topology.
1. If the central switch node (Hub) fails, it may bring down the entire network.
2. It is costly because; each workstation is connected to the central concentrator by is own
dedicated cable (i.e., it requires a lot of cables).
1. Installation is time consuming, because each node forms a segment of its own.
May require a special device for signal regeneration across the network
8. Bus topology (Daisy-chain topology)
In Bus topology, all the devices in the network are connected directly, through appropriate
interfacing hardware, to a single transmission cable called the Bus (or Backbone) on which
information is broadcast.
9. Bus topology uses Coaxial cable as transmission medium. The cable can carry only one
message at a time and each workstation on the network must be able to know when it can and
cannot transmit using this cable.
A Terminator is attached to each end of the cable to avoid signals from bouncing back and forth
on the cable causing signal distortion.
For communication to take place, data is addressed to a particular computer & put in the cable
in the form of electronic signal. As the data passes along the cable, each workstation checks
whether the data is addressed to it. If the address in the data matches that of the machine, it
picks up the data and processes it.
Bus topology doesn’t need any special equipment such as switches or repeaters to amplify the
signal.
Advantages of Bus topology.
1. Easy to install.
2. Inexpensive (less costly) because; it does not require a complete cable length per
computer.
3. Can easily be extended.
4. It allows the workstations to communicate independently (separately) of each other.
5. Failure of one station on the network does not affect the operations on the bus.
Disadvantages of Bus topology.
1. A cable break in each section brings down the whole network.
2. The performance degrades since there is no signal integration.
3. Troubleshooting the cable fault can be quite difficult because; the fault could be anywhere
on the cable.
4. Only a limited number of computers can be connected to the cable. This is because; each
computer is listening to the cable in order to transmit. This means that, if the number of
computers increase, there will be more collision as the workstations compete for
transmission.
10. Ring topology
In a ring topology, the computers are connected to one another in the shape of a closed loop
using a single cable.
11. Data flows from one computer to another in one direction, and each
computer actively participates in data transfer from one station to the
other. In other words, each workstation acts as a booster by regenerating
and retransmitting the signals around the network to its neighbour.
A token is used to exchange data from one station to another. A token
can be viewed as an envelope or a bag where data is placed for
transmission and carried around the network.
Advantages of Ring topology.
1. They use a short length cable.
2. Simple to install.
3. Provides high performance for many users.
4. Provides an orderly network in which every device has access to the
token and can transmit data.
Disadvantages of Ring topology.
1. Failure of one computer or the cable will affect the rest in the entire
network.
2. Modification is difficult because; adding or removing a device can
disrupt the entire network.
3. Troubleshooting can be difficult.
12. Mesh topology
Mesh topology uses separate cables to connect each device to every other device on the network
providing a straight communication path.
It is mostly used in Wide Area Networks where there are many paths between different locations.
13. Advantages of Mesh topology.
1. It is fast.
2. Failure on one node will not cause communication
breakdown.
3. Easy to troubleshoot cable problems. If two
machines are not communicating, the administrator will
only check the cable between them.
4. Enhances flexibility in communication.
5. Enhances fault tolerance provided by redundant/
excessive links.
14. Disadvantages of Mesh topology
1. Difficult and expensive to install and maintain.
2. Very costly as it requires large amounts of cables (or
redundant links).
3. Difficult to add more nodes when the network is large.
4. Difficult to isolate faults due to lack of a central control
point
15. Tree (Hierarchical) topology
This is a hybrid topology where groups of star-configured networks are connected to a linear bus
(backbone).
