virtual reality  : Virtual reality (VR) , the use of  computer  modeling and simulation that enables a person to interact with an artificial three-dimensional (3-D) visual or other sensory  environment . Early work: Artists, performers, and entertainers have always been interested in techniques for creating imaginative worlds, setting narratives in fictional spaces, and deceiving the senses. Numerous precedents for the suspension of disbelief in an artificial world in artistic and entertainment media preceded virtual reality. Education and training: An important area of application for VR systems    has always been training for real-life activities. The appeal of simulations is that they can provide training equal or nearly equal to practice with real systems, but at reduced cost and with greater safety.  Entertainment: As virtual worlds became more detailed and immersive, people began to spend time in these spaces for entertainment,  aesthetic ...

What is Blockchain Technology? How Does Blockchain Work?   What Is Blockchain Technology? Blockchain is a method of recording information that makes it impossible or difficult for the system to be changed, hacked, or manipulated. A blockchain is a distributed ledger that duplicates and distributes transactions across the network of computers participating in the blockchain. Why is Blockchain Popular? Highly Secure It uses a digital signature feature to conduct fraud-free transactions making it impossible to corrupt or change the data of an individual by the other users without a specific digital signature. Decentralized System Conventionally, you need the approval of regulatory authorities like a government or bank for transactions; however, with Blockchain, transactions are done with the mutual consensus of users resulting in smoother, safer, and faster transactions. Automation Capability It is programmable and can generate systematic actions, events, and payments automatically wh...

 Cloud Computing Innovations: it is another technology that is revolutionizing the IT industry. It refers to the delivery of computing services, such as servers, storage, databases, networking, software, and more, over the internet. Cloud computing offers various benefits for IT professionals, such as scalability, flexibility, cost-efficiency, and reliability. On-demand self-service.  A consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with each service provider. Broad network access.  Capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, tablets,  laptops , and workstations).          Resource pooling .  The provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with di...

Title : How AI change the world introduction:  Innovations in the field of artificial intelligence continue to shape the future of humanity across nearly every industry such as big data, robotics and IOT. similarly  it also effect the daily life of normal human beings. Body: 1. Improved Business Automation: First and foremost 55 percent of organizations have adopted AI . Secondly the rise of chatbots and  digital assistants  companies depend upon AI to handle simple conversations and queries with employee and customers . 2.AI in Education : AI in education will change the way humans of all ages .  On other hand AI use of machine learning , natural language processing and facial recognition help digitize  text books detect plagiarism and gauge  the emotions of student to help who's struggling or bored . 3.AI in Transportation: AI changed the industry of transportation there are many self  driving cars and AI based vehicles are available in market. ...
