In the present time, if we see around the world we can realize that information transfer through one place to another is very easy. A person lives in America easy do business with the person live far away from it. All this can be achieved by the phenomenon known as Networking. And the device through which the information are transferred are called interconnected device. As we know, in present time our need is not only transfer or sharing of information but in a secure way. So with the help of this we are not just transferring the information but in a secure manner To understand the whole phenomenon of this networking, the basic requirement is OSI LAYER Model. This is not just a model but a complete frame which gives us whole information of its working as well as link between them. So through this paper we give some basics concept building of OSI LAYER which help in understanding the Networking

The article actualizes the study of websites as a means to promoting cities around the world and highlights the main structural and semantic characteristics of advertising sites hosted on Internet platforms. The pragmatic role of a lexical unit of advertising texts is investigated. The concepts of website and advertising text are defined, the main ways of information transfer through advertising text were described. Definitions of the concepts such as advertising, advertising text, strategy, website, and related concepts are provided. After researching the selected advertising texts, the structural and semantic characteristics of advertising on websites, and the main ways of transmitting information, such as verb sentences, simple nominative sentences, and elliptical sentences are analyzed. The pragmatic means of advertising campaigns on websites includes constructions, such as Top + Numeral, Must + V., Let + Inf, and so on. Examples of pragmatic websites are also considered. Samples and purposes of using this approach are given. There are various strategies for advertising and promoting cities and countries around the world on Internet platforms. The most popular and effective are the use of different language techniques (motivational, interrogative, negative sentences) and the strategy of the association. The advertising text is noted to embody a communicative and pragmatic guideline. In the advertising message, there is a presentation of the goods to the target audience. Thus, the main load is the language code, which is aimed at a special category of people. A small number of works on this topic indicate the need for a more detailed study of the issue.

One pertinent area of recent m-commerce development is in methods for personal transaction and information transfer. Several companies around the world have begun to use barcodes for the provision of m-commerce services. This chapter provides background on the enabling technological platform for providing such services. It then continues with three cases where mobile barcodes have been used—in Japan, New Zealand, and the UK. Subsequently, these are used as the basis for a discussion and analysis of the key business models, and strategic implications for particular markets. The chapter concludes with predictions for the market and directions for future research.

To formulate a philosophy of time is not easy, even though it would seem to be the basic requirement for any philosophy which attempts to comprehend the world of nature or of history. The problem is briefly posed: Can the conceptual framework of philosophical thought do justice to the dynamic character of time?The purpose of this paper is not to provide a definitive answer to this question. Its aim is more limited. By discussing carefully the way in which Hegel's philosophy related conceptual thought to time, it hopes to provide new perspectives on this vexing philosophical problem.

<p>The main interesting aspect of the digital era is the widely spread ease of communication from one end of the world to the other end of the world. There is a revolution in communication, digitalization, globalization, video calling, wireless data transfer and this is possible due to networking. Initially computer networks is the data sharing where data such as documents, file, reports, presentation files, videos, images etc can be shared within a local network or remotely connected networks. Traditional data networking is to empower end-to-end information transfer. The data in such networks are carried across point-to-point links and the intermediate nodes just forward the packets, where the payload of the packets is not modified. Traditional LANs need wires, which may be difficult to set up in some situations.</p><p>It is very much understandable and clearly visible that wired communication is being completely overtaken by wireless technologies in the recent past. Wireless LANs, by its very nature, empowers with increased mobility and flexibility. Wi-Fi devices get connected to the internet through WLAN and access points. 2.4 GHz and 5 GHz ISM bands are used by Wi-Fi. Also, it is to be understood that, a wireless adhoc network is distributed in its nature. It is also to be noted that, the adhoc nature makes these network to rely on any of the pre-existing infrastructure. The data forwarding shall happen from the nodes very much dynamically based on the connectivity and the routing algorithm used.  </p>

Chickpea (Cicer arietinum) is one of the most important pulse crops but it’s productivity in India is quite low. There are various reasons for low productivity. Weed control is the basic requirement and the major component of crop management. Weeds on an average reduce the crop yield by 40-87 per cent. Deciding time to control weeds requires detailed knowledge of the weed populations in the field. Different management practices like altering spacing, competitive cultivars, etc. can help in enhancing the productivity. With the world entering the precision-farming era, more emphasis is being put on the use of post-emergence herbicides. Application of two or more herbicide at the same time or as a double knockdown and integrating with hand-weeding provides desirable control of different weed species besides reducing the hazard of chemical weed control.

The digital revolution is changing the world. Robots, big data and artificial intelligence are the key technologies of the future and the basis of important innovations for the future development of the economy and society. In companies, this fact requires strategic rethinking and adjustments in ever-shorter time cycles. The creation of an agile and collaborative production to achieve the goals is often a basic requirement. With adaptation to technical progress, requirements and goals change continuously. To be and remain competitive, companies are forced to have at least the same technological standard as their competitors. In order to meet these challenges today, the use of highly efficient mechatronic systems such as robots is necessary. The paper analyses business ethics relevant aspects of robotics by using a survey with 88 respondents.

Higher education dropout has been considered a major concern for several researchers in the field of education around the World. Although different studies were carried out to deal with the topic, they all faced common limitations. This paper explores the twofold research conducted to investigate higher education dropout in Education studies at two of the main Catalan public universities. First, a review of the different theoretical perspectives that tackled dropout was carried out to combine the direct and indirect dropout predictors. Second, some research was conducted in the faculties of Education in the selected two Catalan public universities to investigate the antecedents of higher education dropout. The utilized instrument discussed in this paper is the survey. In the first part, the predictors of higher education dropout were combined in a 5-layer model called the ¨Dimensions of Academic Dropout” wheel (Naaman, 2018). In the second part, the results of the survey analyzed quantitively revealed that dissatisfaction from the program and academic failure are the most important antecedents of higher education dropout in education studies in Catalonia.

The information transfer protocol that supports the modern Internet with its hundreds of thousands of petabytes per month to billions of Internet users across the world was designed in 1981, and it lacks the capacity to properly ensure the security and stability of the Internet today. Features such as the prevention of network attacks, a large address space for the increasing number of devices, verification of the source of an Internet request, and so on are all absent from the current architecture. This paper seeks to review, summarize, and compare six proposals submitted to address the issues IP faces: the Accountable Internet Protocol, the Expressive Internet Architecture, MobilityFirst, Passport, StopIt, and the Traffic Validation Architecture. Finally, the paper details a protocol design that not only is feasible to adopt with the present infrastructure/computing power but also addresses some of the pressing issues of IP, with particular focus on the address space, mitigation of network attacks, and source verification.

High-efficiency, energy-saving and environment-protection have become the current consensus of the world. The basic requirement of energy-saving for domestic appliances and electronic products has been accomplished to reduce the power on standby. The key point of energy-saving is to decrease the loss damaged in the switch. Boost converter (DC/DC) is a lower-loss, higher-efficiency module with the 90% conversion rate.

COVID-19 and the lockdown have challenged urbanists to rethink many of their core practices. As we return to a ‘new normal’, it is important to articulate responses to present challenges through the manner in which we have taught Southern urbanism over the last decade. One of the early lessons of Southern urban practice was that the field had to be our primary site of pedagogy. It is important, too, to recognise and value what this experience teaches us about theory, knowledge and practice. Over the last decade, I have been among a small band of urbanists in India and across the world who have been attempting to craft new learning and teaching contexts where experience and sensory perceptions are privileged but not at the expense of abstraction and concept building. As we witness uncertainty of an unprecedented degree, it is only through praxis and concept-forming informing each other that new theory will emerge. It will not emerge from any single source. This democratisation of practice is the single most important outcome of the last 3 months.
