In recent years, the cloud has achieved an immense popularity in the world of tech. This has provided new and improved strategies for cost reduction, and for ensuring better utilisation of cloud resources. Implementation of this model is continuously increasing in numerous businesses , due to the many benefits that the companies are attaining. These cloud resources can belong to either, the infrastructure or platform model. A vast attention has been directed towards the virtualization technology, because the cloud is largely relied upon it. With the help of virtualization, one can quickly download apps or websites, from the cloud. In order to yield the full potential of the cloud, companies should migrate all their current applications to the cloud, and in order to do that- only an internet connection is required. Migration of the existing systems to a scalable cloud solution, can reduce hardware related costs , such as : servers, installation of operating system, database and licence system costs, deployment of database products , and finally employment of professional  staff to develop and maintain the system. This research attempts to study and analyze Microsoft Azure, in particular the virtual machine - as part of its infrastructure. The main priority lies in establishing a secure cloud data storage system.

Nowadays, software applications are entwined in every area of life. It is almost inevitable. In addition to helping businesses, software’s also facilitates over jobs and services, such as: in libraries. These software’s are created through high programming languages, namely Java, C#, Python etc.  Nonetheless, we can also create them while using applications from the Microsoft Office Package. One of these applications is Microsoft Excel. It has all the tools we need. This software application is created through Microsoft Excel for the sole reason that it is familiar to the majority of users, one of whom are librarians. The application comprises five pages: Content,Book Fund, Remaining Book Fund, Readers and Realization. The link between these pages will be done by numerous different functions, such as: if, sumif, sum, vlookup, etc.

- The enormous increase of online shopping, sales and online orders is disproportionate to the knowledge of the users of these services. The purpose of this paper is to understand how online shopping and orders are perceived by people who are directly or indirectly involved in online e commerce services. The study utilized questionnaires in the collection of data. Data was analyzed using Excel and percentages. Based on the results of the conducted study, it was revealed that very few people know how to distinguish between online shopping and online orders. The same hypothesis can be used to explain what e-commerce is.

Abstract— The purpose of this paper is to show the design technique and programming of an autonomous robot prototype that can go to a predetermined location and return to its starting place utilizing the Global Positioning System (GPS). An HD camera along with an ultrasonic sensor and two IR sensors is used to provide necessary data from the real world to the robot to avoid obstructions, by following GPS Waypoints. A smart algorithm was introduced for path planning and re-planning. The robot can modify its direction using a digital compass reading and input from sensors by computing the heading angle from the current GPS point. This self-navigation mobile robot's accuracy was evaluated in several locations and is quantified in terms of heading angle and path length from the starting point to the goal point.
