Computer networks and its components by narender singh sandhuNarenderSinghSandhu2
A computer network is a group of computers that are connected to each other for the purpose of communication. Networks may be classified according to a wide variety of characteristics. This article provides a general overview of types and categories and also presents the basic components of a network.
One way to categorize the different types of computer network designs is by their scope or scale. For historical reasons, the networking industry refers to nearly every type of design as some kind of area network. Common types of area networks are:
LAN - Local Area Network
WAN - Wide Area Network
WLAN - Wireless Local Area Network
MAN - Metropolitan Area Network
SAN - Storage Area Network, System Area Network, Server Area Network, or sometimes Small Area Network
CAN - Campus Area Network, Controller Area Network, or sometimes Cluster Area Network
PAN - Personal Area Network
LAN and WAN are the two primary and best-known categories of area networks, while the others have emerged with technology advances

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.
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.
2. COMPUTER NETWORK
A computer network is a collection of computers and other
hardware interconnected by communication channels that allow sharing of
resources and information. Where at least one process in one device is able
to send/receive data to/from at least one process residing in a remote
device, then the two devices are said to be in a network. A network is a
group of devices connected to each other.
4. Communication protocols define the rules and data
formats for exchanging information in a computer network, and
provide the basis for network programming. Well-known
communications protocols include two Ethernet, a hardware and
link layer standard in local area networks, and the Internet protocol
suite which defines a set of protocols for internetworking, i.e. for
data communication between multiple networks, as well as hostto-host data transfer, and application-specific data transmission
formats.
5. Properties
Computer networks:
1. Facilitate communications
Using a network, people can communicate efficiently and easily via email, chat rooms,
telephone, video-calls, and video conferencing.
2. sharing of files, data, and other types of
information
In a network, authorized users may access data and information stored on other
computers on the network.
3. Share network and computing resources
In a networked, each computer on a network may access devices on the network, such
as printing a document on a network printer.
6. 4. Share network and computing resources
In a networked environment, each computer on a network may access and
use resources provided by devices on the network, such as printing a
document on a shared network printer.
5. May be insecure
A computer network may be used by computer hackers to deploy
computer viruses or computer worms on devices connected to the
network, or to prevent these devices from normally accessing the network
6. May be difficult to set up
A complex computer network may be difficult to set up. It may also be very
costly to set up an effective computer network in a large organization or
company
7. WIRED TECHNOLOGIES
• Twisted Pair-wire is the most widely used medium for telecommunication. Twistedpair cabling consist of copper wires that are twisted into pairs. Ordinary telephone
wires consist of two insulated copper wires twisted into pairs.
•Coaxial Cable is widely used for cable television systems, office buildings, and other
work-sites for local area networks. Transmission speed ranges from 200 million bits
per second to more than 500 million bits per second.
8.
9. WIRELESS TECHNOLOGY
•Terrestrial MicrowavE – Terrestrial microwave communication uses Earth-based
transmitters and receivers resembling satellite dishes. Terrestrial microwaves are in the
low-gigahertz range. Relay stations are spaced approximately 48 km (30 mi) apart.
•Communications satellites – The satellites communicate via radio waves, which are not
deflected by the Earth's atmosphere. The satellites are stationed in space typically
about 35,400 above the equator. These Earth-orbiting systems are capable of receiving
and relaying voice, data, and TV signals.
•Cellular and PCS systems use several radio communications technologies. The systems
divide the region covered into multiple geographic areas. Each area has a low-power
transmitter or radio relay antenna device to relay calls from one area to the next area.

11. LOCAL AREA NETWORK
A Local Area Network (LAN) is a network that connects computers
and devices in a limited geographical area such as home, school, computer
laboratory, office building, or closely positioned group of buildings. Each
computer or device on the network is a node. Current wired LANs are most
likely to be based on Ethernet technology, although new standards like ITU_T
also provide a way to create a wired LAN using existing home wires (coaxial
cables, phone lines and power lines). LAN technologies operate at data
transfer rates up to 10 G bit/s.
12.
13. WIDE AREA NETWORK
A Wide Area Network(WAN) is a computer network that covers a
large geographic area such as a city, country, or spans even intercontinental
distances, using a communications channel that combines many types of
media such as telephone lines, cables, and air waves. A WAN often uses
transmission facilities provided by common carriers, such as telephone
companies. WAN technologies generally function at the lower three layers of
the OSI reference model: the physical layer, the data link layer, and the
network layer.
14.
15. INTERNETWORK
An Internetwork is the connection of multiple computer
networks via a common routing technology using routers. The
Internetwork is an aggregation of many connected internetworks
spanning the Earth.
16. REPEATERS AND HUBS
A Repeater is an electronic device that receives a signal, cleans it
of unnecessary noise, regenerates it, and retransmits it at a higher power
level, or to the other side of an obstruction, so that the signal can cover
longer distances without degradation. In most twisted pair Ethernet
configurations, repeaters are required for cable that runs longer than 100
meters. A repeater with multiple ports is known as a HUB. This can cause a
prapogation-delay which can affect network communication when there
are several repeaters in a row. Many network architectures limit the
number of repeaters that can be used in a row
Today, repeaters and hubs have been made mostly obsolete by switches

18. NETWORK SECURITY
In the field of networking, the area of network security consists of the
provisions and policies adopted by the network administrator to prevent and monitor
unauthorixed access, misuse, modification, or denial of the computer network and
network-accessible resources. Network security is the authorization of access to data
in a network, which is controlled by the network administrator. Users are assigned an
ID and password that allows them access to information and programs within their
authority. Network Security covers a variety of computer networks, both public and
private that are used in everyday jobs conducting transactions and communications
among businesses, government agencies and individuals.
