  For most of our history, human technology consisted of our  brains, fire, and sharp sticks  while fire and sharp sticks became power plants and nuclear weapons. The biggest upgrade has happened to our brains. Since the 1960s the power of our brain machines has kept growing exponentially allowing computers to get smaller and more powerful at the same time. But this process is about to meet its physical limits.   Computer parts are approaching the size of an atom.  To understand why this is a problem, we have to clear up some basics. A comput e r is made up of very simple components doing some simple things like representing data, the means of processing it, and controlling the mechanisms. Computer chips contain  modules, logic gates, and transistors . A transistor is the simplest form of a data processor in computers, basically, a switch that can either block or open the way for information coming through. This information is made up of bits that can be ei...

SELF DRIVING CARS: So there you are, it’s a rainy night and you’ve called a taxi. Strangely, the driver doesn’t talk but you arrive at the address, Now you want to pay cash and run away screaming.OMG, There is no driver in the car. WAIT WAIT WAIT..This is not a horror movie but the near future of self-driving cars. We don’t know what the future holds but we do know that previous generations had high hopes for what lay ahead. As a new period of massive change is upon us, it’s really hard to notice what is developing over our heads to the inner data spaces being explored by the phones in our pockets. Sure, it’s scary. Self-driving cars could take away jobs from drivers and give machines more power than some ever thought possible . Even so, it’s interesting to see what is actually true and what about these technological wonders has been exaggerated. Let’s quickly head on to our topic. A self-driving car (sometimes called an autonomous car or driverless car) is a vehicle that uses a combin...

  Blockchain: Blockchain are incredibly popular nowadays. But what is Blockchain? Like the name indicates, a blockchain is a chain of blocks that contains information . This technique was originally described in 1991 by a group of researchers and was originally intended to timestamp digital documents so that it is not possible to backdate them or to tamper with them. However it went by mostly unused until it was adapted by Satoshi Nakamoto in 2009 to create the digital cryptocurrency Bitcoin. A blockchain is a distributed ledger that is completely open to anyone. A simple analogy for understanding blockchain technology is a Google Doc. When we create a document and share it with a group of people, the document is distributed instead of copied or transferred. This creates a decentralized distribution chain that gives everyone access to the document at the same time. No one is locked out awaiting changes from another party, while all modifications to the doc are being recorded in re...

The internet has drastically changed the IT industry. It not only connects a person with the world, but it also introduces new features every year. In the last decade, “cloud ” was a new term tossed in the market, and soon it gained so much popularity that it now covers a large area of the industry. With everything from hard disk failures to malware attacks to worry about, backing up your digital data has never been more important. For a long time, copying your data to an external hard disk drive was the least time-consuming and most cost-effective way to back up data.  But the storage landscape has changed dramatically in recent years with Cloud Storage. While very popular these days, the term “cloud” is used very loosely to refer to what is really just files and folders hosted on a remote server and accessed via the Internet . So, when you hear someone speaking of uploading files to the “cloud,” what they are actually saying is that they are using their Internet connection to cop...

  Artificial Intelligence (AI)   In today's world, technology is growing very fast, and we are getting in touch with different new technologies day by day. Here, one of the booming technologies of computer science is Artificial Intelligence which is ready to create a new revolution in the world by making intelligent machines. Artificial Intelligence is now all around us. It is currently working with a variety of subfields, ranging from general to specific, such as self-driving cars, playing chess, proving theorems, playing music, painting, etc. Artificial intelligence (AI) is a wide-ranging branch of computer science concerned with building smart machines capable of performing tasks that typically require human intelligence. The term Artificial Intelligence was first coined decades ago in the year 1956 by John McCarthy. He defined AI as the science and engineering of making intelligent machines. AI is a technique of getting machines to work and behave like humans. In the rec...

INTERNET OF THINGS (IoT) Imagine a world where everything is connected, this concept paves the way to the Internet of Things (IoT). What would you do if you want to share information with another person, you send emails, messages, letters, etc. When a person shares some known details with another person via the internet, it is known as the Internet of people (person-to-person communication) in the same way when a thing or device transfers information to another thing via the internet is known as the Internet of Things.   In technical terms, The Internet of Things (IoT) refers to a system of interrelated, internet-connected objects that can collect and transfer data over a wireless network without human intervention. IoT is influencing our lifestyle from the way we react to the way we behave . IoT is a giant network with connected devices, these devices gather and share data about how they are habituated and the environment in which they are regulated. It's all done using sensors...
