The Transmission Control Protocol and Internet Protocol Layers refers to the communication protocols that enable use to do anything over the internet. There are four layers. In the Network Interface Layer things like sending information between hosts on the same local network and translating data from higher layers are done. The layer right above that would be the Internet Layer where data is packaged into packets, receive incoming packets of data, and addressing and transmitting packets occur. Then there is the Transport Layer this layer is responsible for end-to-end communication on the network. In short, the transport layer collects message segments from the application and transmits the to the nest layer.
Physical Layer – hubs, cables, modems, and repeaters.
Data Link Layer – bridges, switches, NIC’s,
Network Layer – routers, brouters
Transport Layer – gateways, firewalls,
Application Layer – PC’s, smartphones, servers
The TCP/IP Protocol suite was developed in the 1960’s and recognized throughout the world after 1983. As for the OSI reference model it was also recognized throughout the world in 1983. Some key similarities between the TCP/IP and OSI Model is that they describe how data is transmitted between devices on a network. Both models also divide the networking concepts into layers. The ideas about how data is broken down into smaller pieces and passed from layer to layer is the same as well. Another similarity is that these models are used to troubleshoot various networking problems. Both are modular and each layer represents a separate set of functions and protocols. Some of the ley differences between the two would be that the OSI model is a more elaborated model where each layer has separate functionality. Unlike the TCP IP model, it does not combine any layers. The OSI has 7 layers, and the TCP IP has 4 layers. The TCP/IP model is more geared towards networking hardware and software used on the internet as to the OSI models is more general and can be applied to any type of network.

The Seven Layer Model of OSIComment by Prof Thomas: Paper format changes between sections. Review format
The Open System Interconnect (OSI) is a very important concept in networking when considering the creation of a a networking system for the university. “It was created by the international organization of standards 1978 and its main purpose is to help describe the architecture of a network so as make it possible for computers to send and receive data from other computers”. Although the model is conceptual, appreciating its purpose and function will help the university in understanding how the protocol suits and network architecture work on an application basis. The OSI model is usually built from bottom to top in this order; physical, data link, network, transport, session, presentation and lastly application. Every layer of the OSI model has its own special function. The following sections describe the function of each layer.
The layers of the OSI model
Physical Layer (Layer 1)
The OSI model layer identifies the networks’ physical characteristics and specifications. This is the type of media used on the network for example type of connector, cables, and pinout format cables.
Topology
The topography is defined by the physical layer. This layer shows the type of topology to be applied in the network. Additional characteristics in this layer define voltage used on a given frequency and medium at which the signals that carrying the data operates. They dictate speed and bandwidth of a given medium and the maximum distance over which a specific media type can be applied
Data link Layer (Layer 2)
The layer is a designed protocol that operates in a program involved in data movement into and out of a physical link in a network. Layer 2 of the OSI model is responsible for receiving data for layer 1. It is then sent to layer 3 and the data from layer 3 is sent to layer 1. This layer also detects and corrects errors. The word ‘frame’ is usually used to refer to the logical data grouping at this layer. It has two distinctive sub-layers:
· Access control (MAC) - MAC address is the physical/hardware address burnt into each network interface card (NIC). It accesses specific areas that are found within the interior of buildings. Provides access that is faster to the people authorized and restricts access of people not authorized.
· Link control (LLC) – “this controls the error and flows control mechanism of the data link layer [2].” It plays the role of managing the transmissions of data to ensure that there is integrity. For NLC, it has a role of providing data link layers.
· Network Layer (Layer 3).
The primary faction of layer 3 is to giving access to the ways by which information can disseminate to and from different network systems. It does not specify.

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.

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.

The Transmission Control Protocol and Internet Protocol Layers .docx
1. The Transmission Control Protocol and Internet Protocol
Layers refers to the communication protocols that enable use to
do anything over the internet. There are four layers. In the
Network Interface Layer things like sending information
between hosts on the same local network and translating data
from higher layers are done. The layer right above that would
be the Internet Layer where data is packaged into packets,
receive incoming packets of data, and addressing and
transmitting packets occur. Then there is the Transport Layer
this layer is responsible for end-to-end communication on the
network. In short, the transport layer collects message
segments from the application and transmits the to the nest
layer.
Physical Layer – hubs, cables, modems, and repeaters.
Data Link Layer – bridges, switches, NIC’s,
Network Layer – routers, brouters
Transport Layer – gateways, firewalls,
Application Layer – PC’s, smartphones, servers
The TCP/IP Protocol suite was developed in the 1960’s and
recognized throughout the world after 1983. As for the OSI
reference model it was also recognized throughout the world in
1983. Some key similarities between the TCP/IP and OSI
Model is that they describe how data is transmitted between
devices on a network. Both models also divide the networking
concepts into layers. The ideas about how data is broken down
into smaller pieces and passed from layer to layer is the same
as well. Another similarity is that these models are used to
2. troubleshoot various networking problems. Both are modular
and each layer represents a separate set of functions and
protocols. Some of the ley differences between the two would
be that the OSI model is a more elaborated model where each
layer has separate functionality. Unlike the TCP IP model, it
does not combine any layers. The OSI has 7 layers, and the
TCP IP has 4 layers. The TCP/IP model is more geared towards
networking hardware and software used on the internet as to
the OSI models is more general and can be applied to any type
of network.
