  Imagine driving home after a long day of work. En route the car instructs the residence to automatically turn on the lights, prepare a hot bath, and download the latest Netflix series. While this may seem like a line from a SciFi script, the future is more realistic than ever. Welcome to the world of IoT or Internet of Things. Though not as popular as its famous counterpart, Artificial Intelligence, its penetration into the consumer market is indeed extensive. What is IoT...... It is the term used to describe a   device, or set of devices which are connected to the internet,   and also communicate with each other. They can share data obtained from various sensors to a central hub, analyze it using  AI, and take appropriate actions. For example, a smart thermostat can read the room temperature, analyze the same, and adjust the heating system without any human intervention. Another example would be a smart camera which provides video footage when a movement is detect...

  The debate...   Windows or Linux, which is better. The debate has been going on for eons now. The die hard fans of each sing praise of their respective OS, but there needs to be an unbiased view to get a complete picture. The beginning Here Microsoft takes the lead with the entry  before the internet era. Comparitively, Linux is considered a new kid on the block. Windows is based on Windows NT kernel while Linux is based on Unix. Yes, the same kernel used on Mac. Coming to the core topic. Security is paramount in the   modern digital era given the rise of   cyber crime. Here   linux ups the game .   Here are   some features that   strengthens the same Open Source  Linux kernel is free, and anyone can download and make changes according to preferences. There are different versions available, popular being Ubuntu, Kubuntu, Fedora, Mint and Kali. The benefit is that multiple developers work on the same system to resolve bugs and zero day ...

With the advent of digital age, we are more connected than ever. Social media has transcended geographical locations, and no place is out of reach. But with this type of connectivity, there is a rise in the number of antisocial players. Cyber stalking cases has reportedly gone high in recent years.  Stalking is considered as any form of unwanted attention, contact or harassment directed towards an individual. This results in victim's personal space being encroached or taken for granted.  The preparator perform stalking through fake profiles, monitoring social media sites, messages or chat history. They initiate a volley of hate speech or try to tarnish their victim's reputation. Here stalking can be also a form of love addiction. An unrequited love can cause the stalker to perform the above steps as an act of revenge. Mode of Operation Installing a piece of code in the victim's computer for accessing the webcam. The spyware comes bundled with a software which could be do...

There is currently a clash between two main processors, Intel and AMD. Both do bring a fresh perspective, in their respective domains. So how can we choose a processor brand, based on our use priorities. Intel Stands for Integrated Electronics  and is credited for creating the first processor, Intel 8086. The family tree of the same is credited with higher performance, faster clock speed but, more power consumption AMD Stands for Advanced Micro Devices providing affordability and security. Though a late comer, AMD focused on budget friendly, low power consumption chips. What is Clock Speed A CPU is the brain of any computer and determines the rate at which complex operations are processed.  A chip consists of billions of transistors which are opened and closed n number of times during a cycle. This is a benchmark for speed, known simply as Clock Cycle .  The measuring unit is Hertz (Hz). 1 Hz equals to 1 cycle per second. For Example, a 3.2 GHz processor comple...

  Privacy is a major concern when browsing the internet. Your data could be eavesdropped by hackers, companies targeting ads or even rogue state actors. What gets revealed would be personal browsing history, location monitoring, IP addresses to name a few. Enter the tech... Virtual Private Network or simply known as VPN is a technology used to prevent unauthorized access of your private data. Even if a hacker penetrates the network and get hold of data packets, all that is revealed is gibberish.  This is because all the information that passes through your device is encrypted and can be only revealed through a personal key.  Internet Service Provider Before going further, a knowledge of Internet Service Provider (ISP) is needed. They are the backbone of the World Wide Web. ISP provides each device with a unique IP (Internet Protocol) address, bandwidth allocation and network security. When a website is searched, first it goes from your device to the Router or Modem which...

Operating system (OS) is the heart of any computer device controlling tasks like process scheduling, memory management, and driver implementation. There is a large difference between OS used in main frame or desktop computers, and embedded systems Embedded Systems An embedded system is a miniature computer used to perform a single task. This could be a medical device monitoring heartbeat, or a flight control system. Because of size constraints, the processing power as well as memory/storage capacity is less for the same.  Enter the brain Embedded Linux is a stripped-down version of the original Linux kernel, used in desktops. What makes it different is its capability to run in low power embedded systems, such as smart phones, tablets, medical equipment and avionics system. This OS is a classification of RTOS (Real time operating systems). It means they process data in real time mostly from sensors measuring humidity or temperature, and provide output within a fixed deadline   ...
