A network consists of two or more connected computers that share resources and exchange files. There are three main types of networks: local area networks (LANs), wide area networks (WANs), and metropolitan area networks. A LAN connects computers within a small, confined area like a home or office using cables, with one computer acting as a file server to store shared software. In contrast, a WAN connects computers over long distances using technologies like telephone lines, satellites, and radio links to span locations like districts, states, and countries with the Internet as a common example.

LAN_ROHIT_KUMAR_SHAH.pptx
A local area network (LAN) connects computers and devices within a limited geographic area like an office or building. Devices on a LAN are connected through cables, wireless links, or infrared beams and share resources like printers and files. Common types of LANs include Ethernet, Token Ring, Token Bus, and Fiber Distributed Data Interface (FDDI) networks. A LAN allows resources to be shared, communication to be convenient, data to be centralized, and internet access to be shared among connected devices. However, LANs also have costs to implement and maintain and raise security and privacy concerns.
Computer Network
A network allows connected devices like computers and printers to share information and resources. It has components like network interface cards, hubs, and cables. There are three main types of networks: local area networks (LANs) cover a small area like a home or office; metropolitan area networks (MANs) span a city; and wide area networks (WANs) connect LANs over a larger geographic area or globally. The Internet is the largest global WAN that facilitates communication services between devices worldwide. An intranet is a private network internal to an organization that functions similarly to the Internet but is only accessible by those within the organization.

Problems and Prospects of Border Trade between North east India and Bangladesh
Abstract: Though trade between India and Bangladesh forms only a small part of the total trade, enhancing bilateral trade is of high importance to both countries. For India, increase in trade with Bangladesh would help to address many concerns of economic isolation of its backward north eastern states and generate new market opportunities for small-scale producers from the impoverished hinterlands of eastern states. For Bangladesh, wider areas of cooperation, investment and allied development opportunities will be thrown open with greater trade openness with India. Moreover, both India and Bangladesh has long-standing commitments toward regional economic cooperation in South Asia, of which their bilateral trade is a significant part. Bilateral economic relation between India and Bangladesh has grown since the latter got independence in 1971, albeit at a slow pace. Ups and downs in the political relations between the two countries have had a strong bearing on development of their economic ties. In recent years, both countries have registered good growth rates and have made significant progress in social development. Bilateral trade has also grown, as a result of open economic policy outlook of both countries. Among South East Asian countries, Bangladesh is the largest trading partner of India, with total bilateral trade crossing US$ 5.5 billion in the year 20122. The two-way trade flow between them was US$ 1.08 billion in year 2002. This puts the annual average growth in trade at about 4.7 percent. The present paper tries to highlight the problems and prospects of border trade for North-East India and Bangladesh as a part of India’s look east policy.
Key words: India’s look East Policy, Bilateral trade, South-East Asia, look-East Policy

Economicimpactoftourism 120712024901-phpapp01
Tourism can have both positive and negative economic impacts on host countries. Positively, it generates foreign exchange earnings, contributes to government revenues through taxes, creates employment opportunities both directly and indirectly, stimulates investment in infrastructure that benefits local communities, and contributes to local economies. However, it also causes leakage when profits flow out of the local economy, enables enclave tourism that does not benefit local businesses, increases infrastructure costs for governments, raises prices for local residents, risks economic dependence on the tourism industry, and creates seasonal jobs. The economic impacts are complex and countries must manage tourism development carefully.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

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.
Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
