Robot
Robot: _ Pepper (above), a humanoid robot developed by SoftBank Robotics, was launched in 2014 and can read human emotions. Over 2,000 companies around the world have adopted Pepper as an assistant to welcome, inform and guide visitors in an innovative way. ____ Section-1 Prologue: What is the first thing that comes to mind when you think of a robot? For many people it is a machine that imitates a human—like the androids in Star Wars, Terminator and Star Trek: The Next Generation. However much these robots capture our imagination, such robots still only inhabit Science Fiction. Science-fiction films and novels usually portray robots as one of two things: destroyers of the human race or friendly helpers. People still haven’t been able to give a robot enough ‘common sense’ to reliably interact with a dynamic world and the independent intelligent machines seen in science fiction are still a […]
The Chip
The Chip: _ Figure below shows chip manufacturing facility: ______ Section-1 Prologue: More than 100 years ago, humans invented vacuum tubes that made electricity flow in different directions or get stronger. The tubes made it possible to invent radios, televisions and computers. Every electronic device like a computer and radio works by controlling and manipulating the flow of electric current through a network of interconnected elements like capacitors, diodes and transistors. Before the invention of the chip, electronic devices such as computers and radios used vacuum tubes, or valves, which were cumbersome, heavy and generated a large amount of heat while consuming a lot of power. A 1940s computer called the ENIAC with vacuum tubes about the size of an adult thumb was about the same length and weight as three to four double-decker buses and contained 18,000 vacuum tubes, 7,200 crystal diodes, 1,500 relays, 70,000 resistors, 10,000 […]
ARTIFICIAL INTELLIGENCE (AI)
Artificial Intelligence (AI): _____ ______ Prologue: Mention Artificial Intelligence (AI) and most people are immediately transported into a distant future inspired by popular science fiction such as Terminator and HAL 9000. While these two artificial entities do not exist, the algorithms of AI have been able to address many real issues, from performing medical diagnoses to navigating difficult terrain to monitoring possible failures of spacecraft. In the early 20th century, Jean Piaget remarked, “Intelligence is what you use when you don’t know what to do, when neither innateness nor learning has prepared you for the particular situation.” A 1969 McKinsey article claimed that computers were so dumb that they were not capable of making any decisions and it was human intelligence that drives the dumb machine. Alas, this claim has become a bit of a “joke” over the years, as the modern computers are gradually replacing skilled practitioners in fields […]
INTERNET CENSORSHIP
INTERNET CENSORSHIP: _ Caveat: Please do read my previous article on ‘The computer and internet” before you read this article as it will make basics of computer & internet easy. Various circumvention techniques discussed in this article are purely for educational purpose and cannot evade existing laws of land. All court orders by competent court must be respected regarding viewing and/or publishing objectionable content on Internet. In many jurisdictions, accessing blocked content is a serious crime, particularly content that is considered child pornography, a threat to national security, or an incitement of violence. Thus it is important to understand the circumvention technologies and the protections they do or do not provide and to use only tools that are appropriate in a particular context. Great care must be taken to install, configure, and use circumvention tools properly. I am not expert on computers, internet or information technology; and therefore technical […]
