Broadband refers to high-speed internet access via technologies like DSL, cable, satellite, and wireless networks. DSL provides transmission over existing phone lines at speeds from hundreds of Kbps to Mbps, depending on distance from phone lines. Cable uses the existing cable TV network for internet access. Satellite internet is transmitted wirelessly via satellite dish and available anywhere but is expensive and weather-dependent. Wireless networks connect devices without cables using technologies like Wi-Fi, Bluetooth, and wireless wide area networks (WWANs) using cell towers. Each technology has advantages in speed, mobility, range, and costs, but also limitations.
Satellite broadband is a type of broadband connection Rajnagar that uses satellite technology to provide internet access. It is typically used in rural areas where other types of broadband may not be available. However, satellite broadband can be more expensive than other options and may not provide the same speed and reliability.
In data communication,
Transmission media is a pathway that carries the information from sender to receiver.
We use different types of cables or waves to transmit data.
Data is transmitted normally through electrical or electromagnetic signals.
Synchronous optical networking (SONET) is a standardized digital communication protocol that is used to transmit a large volume of data over relatively long distances using a fiber optic medium. With SONET, multiple digital data streams are transferred at the same time over optical fiber using LEDs and laser beams.
NETWORKA group of autonomous computers and associated devices connected together
by communication channels like cables or telephone lines etc. is called a network.In a network, the computers work as stand alone machines but can communicate
with other computers on the network as and when required.

INTRODUCTION:
Wireless Fidelity termed as Wi-Fi uses the IEEE 802.11 specification to create a wireless local-area network.
A Wi-Fi network basically consists of a wired connection to the Internet that leads to a wireless router for transmutation and receiving data from individual devices, connecting them not only to the outside world but also to each other.
HOW WIFI WORKS?
1. All devices use a wireless adapter to convert request into a radio signal and broadcasts it into the air.
2. The Wi-Fi device, or wireless router, picks up the signal and translates it back into its original form.
3. The router passes the request to the Internet using a hardwired connection.
4. The Internet returns the requested information to the router across the same connection.
5. The router converts the information into a radio signal and broadcasts it into the air.
6. The computer or cell phone's wireless adapter picks up the information and displays it on your screen
WIFI TOPOLOGIES
Wifi have following topologies
AP-based topology (Infrastructure Mode)
Peer-to-peer topology (Ad-hoc Mode)
Point-to-multipoint bridge topology
Wi Fi Network
Wireless Standards
802.11
In 1997, the Institute of Electrical and Electronics Engineers (IEEE) created the first WLAN standard. They called it 802.11 after the name of the group formed to oversee its development. Unfortunately, 802.11 only supported a maximum network bandwidth of 2 Mbps - too slow for most applications. For this reason, ordinary 802.11 wireless products are no longer manufactured.
Wireless Standards
802.11b
IEEE expanded on the original 802.11 standard in July 1999, creating the 802.11b specification. 802.11b supports bandwidth up to 11 Mbps, comparable to traditional Ethernet.
Wireless Standards
802.11a
Supports bandwidth up to 54 Mbps and signals in a regulated frequency spectrum around 5 GHz. This higher frequency compared to 802.11b shortens the range of 802.11a networks. The higher frequency also means 802.11a signals have more difficulty penetrating walls and other obstructions.
Wireless Standards
802.11g
Attempts to combine the best of both 802.11a and 802.11b. 802.11g supports bandwidth up to 54 Mbps, and it uses the 2.4 Ghz frequency for greater range. 802.11g is backwards compatible with 802.11b, meaning that 802.11g access points will work with 802.11b wireless network adapters and vice versa.
Wireless Standards
802.11n
The newest IEEE standard in the Wi-Fi category is 802.11n.
802.11n connections support data rates of over 100 Mbps. 802.11n also offers somewhat better range over earlier Wi-Fi standards due to its increased signal.

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.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

2. What exactly is broadband?
The term broadband commonly refers to high-speed Internet access that is always on and faster
than the traditional dial-up access. Broadband includes several high-speed transmission technologies
such as:
1. DSL
2. Cable
3. Satellite
4. Wireless network
DSL
DSL is a wireline transmission technology that transmits data faster over traditional copper telephone lines
already installed to homes and businesses. DSL-based broadband provides transmission speeds ranging from
several hundred Kbps to millions of bits per second (Mbps). The availability and speed of your DSL service may
depend on the distance from your home or business to the closest telephone company facility.
3. Pros of DSL
The cost of DSL is sometimes cheaper than other internet services.
There are no new wires needed for service. DSL runs over standard phone lines.
It’s always on – no need to dial in or wait for services to start up.
Cons of DSL:
Typically service is provided by the phone company, which means you’ll also likely be required to carry
phone service.
Speeds are dependent on your proximity to the DSL main distribution point. The closer you are the
faster your service will be. Your speed will slow down the farther you get from the main distribution
point.
Some DSL providers implement data caps
4. Cable
Cable internet uses the pay TV cable network to bring us broadband internet access
Pros
1. doesn’t tie up the phone line while we are on internet
2. It is cheaper than other technologies
3. There Is no need to dial-up the internet
Cons
1. Cable in not available everywhere
2. Some building may not be cabled internaly
5. Satellite
Rather than relying on a network of broadband wires or cables, satellite broadband is transmitted
wirelessly via a satellite dish. It works in a similar way to satellite TV, except those services just receive
information. With a satellite broadband connection you also send out – or upload - data to the
satellite.

Pros
1. It is available everywhere
2. A single satellite service provider can support a large numbers of users within the satellite
footprints
Cons
1. It is expensive(Prices start at around £20 a month, rising to more than £100)
2. It can be affected by bad weather
6. Wireless network
Wireless networks are computer networks that are not connected by cables of any kind. The use of a wireless
network enables enterprises to avoid the costly process of introducing cables into buildings or as a connection
between different equipment locations. It is classified into 2 types
1. WLAN(wireless local area network)
2. WWAN(wireless wide area network)
WLAN
A wireless local area network (WLAN) is a wireless distribution method for two or more devices. WLANs use high-
frequency radio waves and often include an access point to the Internet. A WLAN allows users to move around the
coverage area, often a home or small office, while maintaining a network connection. Popular WLAN technology are:-
Wi-Fi (Wireless fidelity)
Bluetooth
Wi-Fi (Wireless fidelity)
Wi-Fi is the wireless technology used to connect computers, tablets, smartphones and other devices to the
internet. Wi-Fi is the radio signal sent from a wireless router to a nearby device, which translates the signal into data
you can see and use.
8. Bluetooth
Bluetooth® refers to a wireless technology which allows digital devices to easily transfer files at high speed.
Bluetooth is common in many portable devices such as laptops, PDAs, mobile phones, smartphones and tablets.
Pros
1. Avoids interference from other devices
2. Easily upgradeable
3. Lower power consumption
4. Free to use
5. Used for transfer voice and data
Cons
1. Has low bandwidth
2. Allows only short range communication between devides
3. Can loose connection
9. WWAN
A wireless wide area network (WWAN). Also called "wireless broadband" or "broadband wireless," wireless WANs
use cell towers to transmit a radio signal within a range of several miles to a moving or stationary device.
Pros
1. Flexible to use
2. New nodes can be added
3. Can be use in remote area
Cons
1. It is costly
2. High security risk
3. It uses line-of-sight between receiving and transmitting points.
