What is Networking?
A computer network is defined as the interconnection of two or more computers. It is done to enable the computers to communicate and share available resources.
Application:
• Sharing of resources such as printer.
• Sharing of expensive software's and database.
• Communication from one computer to another computer.
• Exchange of data and information among users via network.
• Sharing of information over geographically wide areas.

Embracing GenAI - A Strategic ImperativePeter 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.
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
2. Computer Networks
Computer network connects two
or more autonomous computers.
The computers can be
geographically located anywhere.
Introduction to Computer Networks
3. PAN, LAN, MAN & WAN
Introduction to Computer Networks
Network in small geographical Area (Room) is called PAN
(Personal Area Network)
Network in small geographical Area (Room, Building or a
Campus) is called LAN (Local Area Network)
Network in a City is call MAN (Metropolitan Area Network)
Network spread geographically (Country or across Globe) is
called WAN (Wide Area Network)
4. Applications of Networks
Resource Sharing
Hardware (computing resources, disks, printers)
Software (application software)
Information Sharing
Easy accessibility from anywhere (files, databases)
Search Capability (WWW)
Communication
Email
Message broadcast
Remote computing
Distributed processing (GRID Computing)
Introduction to Computer Networks
6. Personal Area Networks (PAN)
A personal area network — PAN is a personal devices network
equipped at a limited area. PAN ordinary has such mobile
devices: cell phone, tablet, laptop. That type of network
could also be wirelessly connected to Internet.
A personal area network handles the interconnection of IT
devices at the surrounding of a single user. Generally, PAN
contains from following such appliances: cordless mice and
keyboards, cordless phone, Bluetooth.
7. Advantages of PAN
No need of extra cable and wire
Used in office, conference, and meetings
It is used in TV remotes, AC remotes, etc.
Data can Synchronize between different devices
Connect to many devices at a time
8. Advantages of PAN
No extra space requires
Affordable Cost
Portable
Easy to use
Reliable
Secure
9. Disadvantages of PAN
PAN can be operated in less range of areas
Can only be used for personal area
Slow data transfer
Interfere with radio signals
Infrared signals travel only in a straight line
12. Local Area Networks (LANs)
Local Area Networks are privately-owned networks
within a small area, usually a single building or
campus of up to a few kilometers.
Since it is restricted in size, that means their data
transmission time can be known in advance, and the
network management would be easier.
13. Cost reductions through sharing of information and
databases, resources and network services.
Increased information exchange between different
departments in an organization, or between
individuals.
Motivations for
Local Area Networking
The growing demand for local area networks is due
to technical, economic and organizational factors:
14. The trend to automate communication and
manufacturing process.
Improve the community security.
Increasing number and variety of intelligent data
terminals, PCs and workstations.
Motivations for
Local Area Networking
17. Transmission Technology used
in LANs
local area networks use either Wi-Fi or Ethernet to connect
computer and devices in a network.
A typical Wi-Fi LAN operates one or more wireless access
points that devices within coverage area connect to. These
access points, manage network traffic which is flowing to
and from the connected devices. In our home, school,
office’s LAN, wireless broadband routers perform the
functions of an access point.
18. Transmission Technology used
in LANs
A typical Ethernet LAN consisting of an ethernet cable to
which all the machines are attached, like in our school
labs, number of computers connected to each other
through the common ethernet cable.
Though Ethernet and Wi-Fi are usually used in most home
and office-based Local area networks, because of both the
low cost and speed requirements, you can also set up a LAN
with fiber optics which is more costly and provide better
communication speed compared to Ethernet LAN or Wi-fi
LAN.
21. A Metropolitan Area Network (MAN) is a
network that is utilized across multiple
buildings
Commonly used in school campuses or large
companies with multiple buildings
Is larger than a LAN, but smaller than a WAN
Is also used to mean the interconnection of
several LANs by bridging them together. This
sort of network is also referred to as a campus
network
Metropolitan Area Networks
(MANs)
22. Metropolitan Area Networks
(MANs)
A Metropolitan Area Network is a system of
LANs connected throughout a city or
metropolitan area. MANs have the
requirement of using telecommunication
media such as voice channels or data
channels.
Branch offices are connected to head
offices through MANs. Examples of
organizations that use MANs are
universities and colleges, grocery chains,
and banks.
26. Wide Area Networks
(WANS)
The main difference between a MAN and a WAN is that the
WAN uses Long Distance Carriers. Otherwise the same
protocols and equipment are used as a MAN.
27. Wide area network
A Wide Area Network is a network spanning a large
geographical area of around several hundred miles to
across the globe
May be privately owned or leased
Also called “enterprise networks” if they are
privately owned by a large company
28. Wide area network
It can be leased through one or several carriers (ISPs-
Internet Service Providers) such as AT&T, Sprint,
Cable and Wireless
Can be connected through cable, fiber or satellite
Is typically slower and less reliable than a LAN
Services include internet, frame relay, ATM
(Asynchronous Transfer Mode)
29. Advantages of WAN
Centralized infrastructure:
One of the main advantage of WAN is the that we do not
need to maintain the backup and store data on local
system as everything is stored online on a data center,
from where we can access the data through WAN.
Privacy:
We can setup the WAN in such a way that it encrypts the
data that we share online that way the data is secure and
minimizes the risk of unauthorized access.
30. Advantages of WAN
Increased Bandwidth:
With the WAN we get to choose the bandwidth based on
the need, a large organization can have larger bandwidth
that can carry large amount of data faster and efficiently.
Area:
A WAN can cover a large area or even a whole world
though internet connection thus we can connect with the
person in another country through WAN which is not
possible is other type of computer networks.
31. Disadvantages of WAN
Antivirus:
Since our systems are connected with the large amount of
systems, there is possibility that we may unknowingly
download the virus that can affect our system and become
threat to our privacy and may lead to data loss.
Expensive:
Cost of installation is very high.
Issue resolution: Issue resolution takes time as the WAN
covers large area, it is really difficult to pin point the
exact location where the issues raised and causing the
problem.
