Whether you love to play DOS games or want to use DOS for some other reason, you need to download the latest version as it supports both old and new DOS commands. Here is this tutorial for you to install DOS operating system.

Scanning your system is a necessary task. But, there are other tasks which are necessary while scanning your PC. This Techvedic tutorial outlines the privacy policy related with scan, what to do if Windows running on your PC can't complete the scan as well as additional information to keep up PC health.

Despite updated operating system, browser, browser add-ons, installed firewall, and acute computer security settings, clever viruses, spyware or Trojans may find loop-holes to slip into your system. Not only in terms of performance, but in terms of stability and security too, these malicious software push you on back-foot. What to do next?

Windows Updates, as you know is a legitimate software update from Microsoft to make the operating system stable and secure for improved performance. By default the feature remains enabled, however, you have the option to configure it further. Set Windows to automatically install updates or get your permission prior to it. Generally, after Windows Update the system automatically shuts down due to the replacement of the Shut Down option in the Start menu with the "Install Updates and Shut Down" button. This phenomenon is sometime irritating.

"Finland's education system, often held up as an exemplary model for the rest of the world, is on the verge of making some major changes. For years, Finland has led the pack in international test scores, becoming a source of fascination for education policymakers and experts. Now, the country is changing the way it teaches students. Going forward, Finnish schools will be placing less emphasis on individual subjects like math and history, and will instead focus on broader, more interdisciplinary topics. The goal, according to Finnish leaders, is to provide students with the necessary skills for a more technological, global society. Here are three things you need to know about Finland's changing education system:"

"Excitement about 3D printing has steadily accelerated over the past decade - but this excitement has largely outpaced innovation and development in the field. As a researcher in 3D printing technologies, I've built 3D printers using all of the major technologies, as well as more experimental ones. What I've learned is that many of these technologies are composed of very well-understood materials, software problems and mechanical systems - things that engineers have been doing for decades. This, then, begs the question: Why isn't 3D printing better? Why are failure rates so high and why is reproducibility so difficult? It's clear that it's not due to working with exotic materials or advanced motion control. What's actually holding back innovation is how we think about those technologies: as separate pieces, rather than as elements of a system. "

"The groundwork for machine learning was laid down in the middle of last century. But increasingly powerful computers - harnessed to algorithms refined over the past decade - are driving an explosion of applications in everything from medical physics to materials, as Marric Stephens discovers When your bank calls to ask about a suspiciously large purchase made on your credit card at a strange time, it's unlikely that a kindly member of staff has personally been combing through your account. Instead, it's more likely that a machine has learned what sort of behaviours to associate with criminal activity - and that it's spotted something unexpected on your statement. Silently and efficiently, the bank's computer has been using algorithms to watch over your account for signs of theft. Monitoring credit cards in this way is an example of "machine learning" - the process by which a computer system, trained on a given set of examples, develops the ability to perform a task flexibly and autonomously. As a subset of the more general field of artificial intelligence (AI), machine-learning techniques can be applied wherever there are large and complex data sets that can be mined for associations between inputs and outputs. In the case of your bank, the algorithm will have analysed a vast pool of both legitimate and illegitimate transactions to produce an output ("suspected fraud") from a given input ("high-value order placed at 3 a.m."). But machine learning isn't just used in finance. It's being applied in many other fields too, from healthcare and transport to the criminal-justice system. Indeed, Ge Wang - a biomedical engineer from the Rensselaer Polytechnic Institute in the US who is one of those pioneering its use in medical imaging - believes that when it comes to machine learning, we're on the cusp of a revolution."

"Just glance at your inbox and odds are you'll find at least one variety of phishing scam or email hack. Whether it's spear phishing, spoofing, account takeovers through embedded malware, or that time-honored plea from a Nigerian prince, there's no doubt that our schools' email systems are under near-constant attack. One careless click of a link can turn a teacher's account into a spam factory, landing your email system on a blacklist and cutting off communication with the rest of the world. Providing employee tax information to a phisher posing as your superintendent, for example, can result in the identity theft of hundreds of employees. The sad truth is that phishing and spamming scams are now part of life in this digital age. But through more engaging education, more authentic practice, and more creative protection practices, schools have a much better chance of mitigating the impact."

"I first became aware that there might be a problem a few years ago, when one of my kids was studying weather systems: high- and low-pressure systems, cold fronts and warm fronts. We were trying to help her prepare for a test and also do some sort of homework, and she didn't get it at all. We were really frustrated, my husband and I, because all we really had as a reference was the top half of this worksheet that explained the concept. So we were having trouble explaining it to her, and at one point I finally said to her, "You know, in your class, didn't your teacher ever draw a diagram on the board?" She said, "No.""

Machines are already superintelligent on many axes, including memory and processing speed. Unfortunately, those are the attributes our education system currently rewards, with an emphasis on learning by rote. It doesn't make sense to me. Part of my job as an investor is to attempt to predict the future - I need to make bets on the way we'll be behaving in the next two, five, ten and 20 years. Computers already store facts faster and better than we do, but struggle to perfect things we learn as toddlers, such as dexterity and walking. We need to rethink the way we teach our children and the things we teach them. Creativity will be increasingly be the defining human talent. Our education system should emphasise the use of human imagination to spark original ideas and create new meaning. It's the one thing machines won't be able to do.

"Never have design thinking, design practice and creative skills been as important to Canada's future as they are now. Today, competitive success is determined by the ability to understand human needs and desires and to deliver richly imagined ways of addressing them. Many organizations recognize the importance of innovation, but they don't know how to achieve it. The answer is design. Designers allow companies to stay ahead of their customers by anticipating and addressing human needs and behaviours in a complex and changing world. Technology needs to be intentionally designed for and with people. Design creates the experience of a product, system or service, the individual, social and cultural experience, and the value and the impact it has. Design is the bridge between raw invention and application. The essence of design thinking involves empathizing deeply, listening to people and observing them to identify tough problems to address or new opportunities to explore. Design thinking marries systems analysis with outcomes-oriented problem solving. It's relevant to the development and enhancement of services, products and business methods. It's as applicable to large companies as it is to startups and non-profits."

The Family of ISO 9000 standards relate to quality management systems and are designed to help organizations ensure they meet the needs of customers and other stakeholders…on other hand ISO 27001, part of the growing ISO 27000 family of standards, is an Information Security Management System (ISMS) standard published in October 2005 by the International Organization for Standardization (ISO).

"I was painfully bored during my K-12 education. I looked forward to college anticipating that it would be different - more engaging, more interesting, more innovative. I was wrong. My undergraduate education, except for a few bright spots, was just an extension of my K-12 education including more grill and drill with sages on the stages (literally since I went to such a large university); taking notes and taking lots of multiple choice tests. During my freshman year, I thought that if I had one wish, it would be to change the educational system (which has stayed with me ever since). One of those bright spots was being asked to read Carl Rogers, Freedom to Learn, which was published 1969 in an upper level Educational Psychology course. The big aha for me was that school systems should be focused on helping learners develop the skills for how to learn not what to learn, one that was sorely lacking in most of my K-graduate-level education and a concept and goal that as an educator I've held onto ever since."

"Students at Snowflake Unified School District created a low cost detection system to alert drivers of animal crossing. Students were split into three teams; the software/hardware team, the design team, and the fabrication team. Community members assisted in tasks, such as cutting the metal and Plexiglas needed for the prototype. Students created a working alert system that uses motion detection and signals to light up roads with animal crossings."

"The Ancient Greeks loved algorithms, and devised lots of useful ones. One of the most famous is the Sieve of Eratosthenes. It is a way to find prime numbers, special numbers that are also known as the atoms of numbers. Prime numbers now form the basis of our most powerful encryption systems upon which digital money is based. Our electronic banking systems (and lots more) would collapse without prime numbers. You can use the Sieve of Eratosthenes as a way to practice times tables, spot patterns and explore how to improve algorithms, whilst also uncovering these mysterious, magical numbers with no obvious pattern of their own. Here you can follow in the footsteps of Eratosthenes and develop your algorithmic thinking skills."

"Although it's difficult to change the way the (school) system operates, it is possible to adjust how you operate within the system. Introducing meditation and mindfulness techniques in the classroom not only allows you to create a calmer environment, the practice has proven to have verifiable benefits on the human brain. A 2011 Harvard study of MRI images showed a thickening in the cerebral cortex (an area responsible in part for attention and emotional integration) in meditation participants in as little as 8 weeks. So, it's more than a good habit and some quiet time in the classroom, you may be helping the brains of your students develop even more than you realize. Where do you even begin teaching meditation when you may not be familiar with the practice yourself? Although it seems like an incongruous match, this is yet another area where technology steps in to make learning convenient, and a variety of apps offer options for every age, ability, and amount of available time. Here are a few to experiment with as you get started."

"Traditionally, we went to school to attain knowledge. The smart kids knew that Columbus discovered America in 1492 and that the square root of 64 is eight. They studied diligently at home so that when the teacher asked a question they could shoot their hand up and be praised for their good work. Today, however, teenagers carry far more information and computing power in their pockets than would ever fit in their heads. So the ability to retain knowledge and manipulate numbers with facility has become, to a large extent, outdated skills. So kids today need to learn how to understand systems and solve problems. "

"I cannot count the number of times I've heard a colleague advise a student to do what makes them happy. Yet I wonder often how many teachers are happy in their jobs. In a 2012 survey, job satisfaction was at a 25-year low, teacher turnover is alarmingly high and costly, and morale is constantly under assault by social and political commentary. But who needs statistics? Just look around during a staff meeting to see the weight educators carry. In an effort to counter these patterns, stakeholders need to build systems of support for each other. It's even better when those support systems are grassroots efforts instead of mandated. One way I've done this for the past several years is through what I call the Hump Day Bump, a compilation of staff-to-staff notes of gratitude and compliments (bumps) emailed to staff each Wednesday."

"Artificial intelligence has been all over headlines for nearly a decade, as systems have made quick progress in long-standing AI challenges like image recognition, natural language processing, and games. Tech companies have sown machine learning algorithms into search and recommendation engines and facial recognition systems, and OpenAI's GPT-3 and DeepMind's AlphaFold promise even more practical applications, from writing to coding to scientific discoveries. Indeed, we're in the midst of an AI spring, with investment in the technology burgeoning and an overriding sentiment of optimism and possibility towards what it can accomplish and when."

"Up until a week ago, I'd never heard of ChatGPT. In fact, I hadn't realised that AI chat systems were even a 'thing' and was quite surprised that the technology existed. For those of you who haven't heard of it yet, ChatGPT, powered by artificial intelligence, is a chatbot which takes human-computer interaction to a whole new level. Siri and Alexa pale in comparison. It is an online system which responds to human input in an incredibly sophisticated way. You type in a request and ChatGPT produces a response within seconds."
