Data can be traced from various consumer sources. Managing data is one of the most serious challenges faced by organizations today. Organizations are adopting the data lake models because lakes provide raw data that users can use for data experimentation and advanced analytics. A data lake could be a merging point of new and historic data, thereby drawing correlations across all data using advanced analytics. A data lake can support the self-service data practices. This can tap undiscovered business value from various new as well as existing data sources. My paper will present the overview of data lake, benefits and it’s architecture along with the opportunities laid down by data lake and advanced analytics, as well as, the challenges in integrating, mining and analyzing the data collected from these sources. It goes over the important characteristics of the data lake architecture and Data and Analytics as a Service (DAaaS) model.

The emphasis of machine learning is on automatic methods. In other words, the goal is to devise learning algorithms that do the learning automatically without human intervention or assistance. The machine learning paradigm can be viewed as "programming by example." Often we have a specific task in mind, such as spam filtering. But rather than program the computer to solve the task directly, in machine learning, we seek methods by which the computer will come up with its own program based on examples that i provide. Before getting to our first learning model, i will need some definitions. An example (sometimes also called an instance) is the object that is being classified. For instance, in spam filtering, the email messages are the examples. Usually, an example is described by a set of attributes, also known as features or variables. For instance, in medical diagnosis, a patient might be described by attributes such as gender, age, weight, blood pressure, body temperature, etc. The label is the category that we are trying to predict. For instance, in spam filtering, the possible labels are "spam" and "not spam". During training, the learning algorithm is supplied with labeled examples, while during testing, only unlabeled examples are provided.

Energy waste altogether adds to expanded expenses in the car fabricating industry, which is liable to energy use limitations and tax assessment from national and global strategy creators and confinements and charges from national energy suppliers. This checking is essential for energy sparing since it empowers organizations to roll out operational improvements to diminish energy utilization and expenses. The primary test to energy observation is the need to incorporate assembling and energy checking and control gadgets that help diverse correspondence conventions and are generally dispersed over a wide region. One of the most significant challenges in the advancement of the Internet of Things (IoT) has been the powering of billions of connected devices. Evaluation of digital services considering an energy impression of the Internet normally requires models of the energy intensity of the Internet. A typical way to deal with the display of the energy intensity is to consolidate assessments of market studies of introduced gadgets on a national or worldwide scale and their related power utilization with the aggregate information volume transported at a similar scale. Energy sources are a fundamental part of society development, and a steady power supply is essential for today’s progress. End-use energy is transferred to various consumers via power transmission and circulation networks after being transformed to optional energy as electricity by various power facilities. The power grid serves as the physical stage for both wide-area electric power sharing and display exchanges, and it is at the heart of auxiliary energy sources. In this manner, it attempts to connect the part of a center point between essential energy and end-use energy. With the bidirectional power stream given by the Energy Internet, different techniques are elevated to enhance and increase the energy usage between Energy Internet and Main-Grid. Energy proficiency and, in addition, quick information transmission are fundamental to green correspondences-based applications for IoT. Here, we are trying to provide a state-of-the-art survey over various Internet of Energy techniques along with IoT.

Agriculture in India is the means of livelihood of almost two thirds of the work force in the country.

A technology enhances a man’s life in every aspect whether it is healthcare, transport, communication, education etc. During this Covid – 19 pandemic, the growths of technology usage have increased enormously. There are various issues and challenges which we face during the use of any technology. Security is the most important aspect, when we are using in any digital platform during Covid – 19. When we think about Cyber Security, the first thing that comes to our mind is “Cyber Crime” which is increasing immensely day by day. Cyber Security refers to the practice of ensuring the integrity, confidentiality and availability (ICA) of information. Basically Cyber security is the state or process of protecting and recovering networks, devices and programs from any type of Cyber Attack. It is comprised of an evolving set of tools, risk management approaches, technologies, training, and best practices designed to protect networks, devices, programs, and data from attacks or unauthorized access. Cyber-attacks in India have risen up to such an extent that our country ranks fourth out of the tenth targeted countries in the world. In this Covid – 19 pandemic Cyber-attacks are an evolving danger to many organizations, employees and consumers in different sectors. They may be designed to access or destroy sensitive data, change any kind of data or extort money. According to a Research, more than 50% of onliners are victim of some of cybercrime every year, which includes computer viruses, malware, credit card fraud, online scams, phishing, and identity theft and so on. These crimes will lead the country to lose millions of rupees or dollars, also time and expenses to put back the things in right directions. This paper mainly focuses on the different aspects of cyber security and the challenges faced in the implementation and by using latest technologies during Covid - 19. The paper also focuses on the India’s legal framework for Cyber Security.
