Open Systems Interconnection
The OSI model is a conceptual framework that characterizes computing functions into a set of rules to support interoperability between networking systems. It divides network communication processes into seven smaller layers - physical, data link, network, transport, session, presentation, and application layer. Each layer has a specific role like the physical layer deals with transmission of raw bits, the network layer handles routing between devices, and the application layer supports programs that use the network. The model allows networks with different hardware and software to communicate in a standard way.

LANs connect computers within a small area like a building using technologies like Ethernet. PANs connect personal devices within 30 feet of an individual. MANs interconnect multiple LANs within a larger area like a city using technologies like Frame Relay. WANs extend over large geographical areas like states or countries using technologies like fiber optic cables and satellites.

Satellites
Satellites orbit Earth in different types of orbits depending on their purpose. Low Earth orbit satellites like those used for scientific research fly only a few hundred kilometers above Earth and complete an orbit in 90 minutes, allowing them to observe different parts of the planet. Medium Earth orbit satellites, including GPS satellites, fly around 20,000 km above Earth and take 12 hours to orbit. High Earth orbit satellites like communications and weather satellites fly at 36,000 km, taking one day to orbit so they remain stationary over one location on Earth.

Topology
This document discusses different network topologies including physical and logical topologies. It describes various common topologies such as bus, ring, star, tree, mesh, and hybrid topologies. For each topology, it provides details on how the nodes are connected and arranged, common examples, and characteristics such as direction of data flow or access methods.
Network Cables
This document discusses the three main types of network cables: fiber optic cable, twisted pair cable, and coaxial cable. Fiber optic cable transmits messages modulated onto light waves through bundles of glass threads. It has a complicated design involving single-mode or multi-mode configurations of the core. Twisted pair cable is ordinary copper wire connecting homes and businesses to telephone companies. The wires are twisted to reduce crosstalk. Coaxial cable carries data through a central conductor surrounded by insulating layers and shielding to prevent signal loss and reduce electromagnetic interference.

CAKE: Sharing Slices of Confidential Data on Blockchain
Presented at the CAiSE 2024 Forum, Intelligent Information Systems, June 6th, Limassol, Cyprus.
Synopsis: Cooperative information systems typically involve various entities in a collaborative process within a distributed environment. Blockchain technology offers a mechanism for automating such processes, even when only partial trust exists among participants. The data stored on the blockchain is replicated across all nodes in the network, ensuring accessibility to all participants. While this aspect facilitates traceability, integrity, and persistence, it poses challenges for adopting public blockchains in enterprise settings due to confidentiality issues. In this paper, we present a software tool named Control Access via Key Encryption (CAKE), designed to ensure data confidentiality in scenarios involving public blockchains. After outlining its core components and functionalities, we showcase the application of CAKE in the context of a real-world cyber-security project within the logistics domain.

Revolutionizing Application Development
with AI-powered low-code, presentation by George Aspiotis, Sr. Partner Development Manager, Microsoft
Artificial Intelligence for XMLDevelopment
In the rapidly evolving landscape of technologies, XML continues to play a vital role in structuring, storing, and transporting data across diverse systems. The recent advancements in artificial intelligence (AI) present new methodologies for enhancing XML development workflows, introducing efficiency, automation, and intelligent capabilities. This presentation will outline the scope and perspective of utilizing AI in XML development. The potential benefits and the possible pitfalls will be highlighted, providing a balanced view of the subject.
We will explore the capabilities of AI in understanding XML markup languages and autonomously creating structured XML content. Additionally, we will examine the capacity of AI to enrich plain text with appropriate XML markup. Practical examples and methodological guidelines will be provided to elucidate how AI can be effectively prompted to interpret and generate accurate XML markup.
Further emphasis will be placed on the role of AI in developing XSLT, or schemas such as XSD and Schematron. We will address the techniques and strategies adopted to create prompts for generating code, explaining code, or refactoring the code, and the results achieved.
The discussion will extend to how AI can be used to transform XML content. In particular, the focus will be on the use of AI XPath extension functions in XSLT, Schematron, Schematron Quick Fixes, or for XML content refactoring.
The presentation aims to deliver a comprehensive overview of AI usage in XML development, providing attendees with the necessary knowledge to make informed decisions. Whether you’re at the early stages of adopting AI or considering integrating it in advanced XML development, this presentation will cover all levels of expertise.
By highlighting the potential advantages and challenges of integrating AI with XML development tools and languages, the presentation seeks to inspire thoughtful conversation around the future of XML development. We’ll not only delve into the technical aspects of AI-powered XML development but also discuss practical implications and possible future directions.

- 3. Computer Network A computer network is a set of devices connected through links. A node can be computer, printer, or any other device capable of sending or receiving the data. The links connecting the nodes are known as communication channels. •Computer Network is a group of computers connected with each other through wires, optical fibres or optical links so that various devices can interact with each other through a network. •The aim of the computer network is the sharing of resources among various devices. •In the case of computer network technology, there are several types of networks that vary from simple to complex level.
- 4. Components Of Computer Network Computer network components are the major parts which are needed to install the software. Some important network components are NIC, switch, cable, hub, router, and modem. Depending on the type of network that we need to install, some network components can also be removed. For example, the wireless network does not require a cable.
- 5. NIC •NIC stands for network interface card. •NIC is a hardware component used to connect a computer with another computer onto a network •It can support a transfer rate of 10,100 to 1000 Mb/s. •The MAC address or physical address is encoded on the network card chip which is assigned by the IEEE to identify a network card uniquely. The MAC address is stored in the PROM (Programmable read-only memory).
- 6. Graduate Record Examinations Value of Using GRE Scores Scores Support Institutions' Efforts to Identify Which Applicants Are Academically Prepared for Graduate-level Study. Scores Provide a Common, Objective Measure to Help Programs Compare Applicants from Different Backgrounds. Important Considerations The Scores Do Not and Cannot Offer Insight Into All of the Qualities that Are Important In Predicting Academic Success or In Confirming Undergraduate Achievement. The Scores Need to Be Interpreted Carefully Because, Like All Tests, They Are Not Exact Measures.
