Update to SHA 2 Or No Security Support for Widnows 7

Windows 7 Support May end soon!
It has been a long time since we have been using Windows 7 operating system for various reasons. It was initially released on 22 July 2009. After few years Microsoft released Windows 8/8.1 and then Windows 10. But many people and organizations are still using Windows 7 as it is rich in features and has a beautiful user friendly environment.


Microsoft is going to stop the software support for Windows 7 by 14 January 2020. Actually it has already ended mainstream support to Windows 7 in 2015. Mainstream support lasts for 5 years from the date of release of the operating system. During the mainstream support Microsoft provides security updates, adds new features and also covers warranty claims. After five years extended support will be given for another five years. During this period Microsoft provides limited support only. It means that it will not add any new features but gives bug fixes and patches. 

Now Microsoft is going to release a new encryption algorithm called SHA-2 (Secure Hash Algorithm) on 12th March. SHA 1 is no more secure with the latest security threats. Owners of Windows 7 PCs need to sign up/ update their OS with SHA 2 till mid of July. Or else Microsoft will not offer security updates to your PC in the times of crisis. Microsoft urges Windows 7 users to get SHA 2 before mid July to get support till 2020.

Artificial Intelligence (AI)

What is Artificial Intelligence(AI)?
AI is the imitation of human intelligence by a machine/system. AI is the study and design of a machine that senses the environment, takes a decision and put it into action. A machine developed with artificial intelligence will have the ability to automatically learn and improve from experience without being explicitly programmed. 



It can think logically and make decisions with less or no mistakes. Due to the accuracy and speed, the impact of AI in everyday life is growing rapidly. For now, this impact seems to be positive and helpful for the users of technology. 

Here are few uses of AI:
·         Email filtering: Artificial Intelligence is used to filter the incoming mails. Based on the rules defined by the user, Email filters can learn to recognize the spam.
·         Speech recognition: AI is used in speech recognition apps to optimize their functionality.
·         Banking: Online Banking systems also use the AI to track unusual activities (fraud detection) on the customer accounts.
·         Online shopping sites use AI for product recommendations and purchase predictions. 
·         Search engines with the help of AI, can predict what a user is going to type
·         There are many other applications that use AI: voice to text apps, personal assistant apps such as Siri, Cortana and Google Now and also Amazon’s Alexa.
·          Self-driving cars is another example for artificial intelligence.

Robotics:
It is a branch of AI which includes the study of making most intelligent and efficient robots. To develop a robot,
·         mechanical engineering is used in planning and designing,
·         electrical engineering is used to power up and control the components
·         computer programs or you can call them the most critical algorithms are used to perform the desired tasks.


But according to many scientists if AI becomes more intelligent than human then it can become a threat to human life. There is another fear many people have is machines with AI can lead to destruction, if put in the wrong hands.
