How Linux is Most Popular Operating System

Today more than 97 percent of the world's supercomputers (including the complete top 10), more than 80 percent of all smartphones, many millions of desktop computers, around 70 percent of all web servers, a large chunk of tablet computers, and several appliances (dvdplayers, washing machines, dsl modems, routers, self-driving cars, space station laptops...) run Linux. 
Linux is by far the most commonly used operating system in the world. 


Linux kernel version 4.0 was released in April 2015. Its source code grew by several hundred thousand lines (compared to version 3.19 from February 2015) thanks to contributions of thousands of developers paid by hundreds of commercial companies including Red Hat, Intel, Samsung, Broadcom, Texas Instruments, IBM, Novell, Qualcomm, Nokia, Oracle, Google, AMD and even Microsoft.

What is Linux Distribution
A Linux distribution is a collection of (usually open source) software on top of a Linux kernel. A distribution (or short, distro) can bundle server …

Artificial Intelligence popular real time application areas

The below 3 IT skills you need to begin you career in Artificial intelligence. I am giving here the real time applications where you can apply artificial intelligence.
Experience writing SQL queries to interface to a MySQL database.Experience with R and Perl programmingExperience with  C ++, C and JavaReal Time Applications:
Medicine: including interpretation of medical images, diagnosis, expert systems to aid GPs, monitoring and control in intensive care units, design of prosthetics, design of drugs. The IntellipathTM pathology diagnosis system has been deployed in hundreds of hospitals worldwide. AI is being increasingly used to provide solutions regarding vector-borne diseases like malaria.
Robotics: including vision, motor control, learning, planning, linguistic communication, cooperative behaviour . Robots are usually trusted with jobs that are deemed dangerous and sometimes impossible for a human being. Today, many industries use them for jobs that are to be performed with utmost e…

IoT Projects guidelines to implement in auto industry

IoT enabling traffic management and control: Cars should be able to organise themselves in order to avoid traffic jams and to optimise drive energy usage. This may be done in coordination and cooperation with the infrastructure of a smart city’s traffic control and management system.

Additionally dynamic road pricing and parking tax can be important elements of such a system. Further mutual communications between the vehicles and with the infrastructure enable new methods for considerably increasing traffic safety, thus contributing to the reduction in the number of traffic
accidents.
IoT enabling new transport scenarios (multi-modal transport): In such scenarios, e.g. automotive OEMs see themselves as mobility providers rather than manufacturers of vehicles.

The user will be offered an optimal solution for transportation fromAto B, based on all available and suitable transport means. Thus, based on the momentary traffic situation an ideal solution may be a mix of individual vehicles, ve…

The three PROTOCOLs leading in IoT

All about PROTOCOL - In telecommunications, a communications protocol is a system of rules that allow two or more entities of a communications system to transmit information via any kind of variation of a physical quantity. These are the rules or standard that defines the syntax, semantics and synchronization of communication and possible error recovery methods. Protocols may be implemented by hardware, software, or a combination of both. Communicating systems use well-defined formats (protocol) for exchanging messages. Each message has an exact meaning intended to elicit a response from a range of possible responses pre-determined for that particular situation. The specified behavior is typically independent of how it is to be implemented. Communications protocols have to be agreed upon by the parties involved.

To reach agreement, a protocol may be developed into a technical standard. A programming language describes the same for computations, so there is a close analogy between pro…

How to Identify Data Relevant for Data Science Analytics

Data is everywhere
your government, your web server,your business partners, even your body. While we aren’t drowning in a sea of data, we’re finding that almost everything can (or has) been instrumented. We frequently combine publishing industry data from Nielsen Book Scan with our own sales data, publicly available Amazon data, and even job data to see what’s happening in the publishing industry.

Sites like Infochimps and Factual provide access to many large datasets, including climate data, MySpace activity streams, and game logs from sporting events. Factual enlists users to update and improve its datasets, which cover topics as diverse as endocrinologists to hiking trails.

How the data is growing
Much of the data we currently work with is the direct consequence of Web 2.0, and of Moore’s Law applied to data. The Web has people spending more time online,and leaving a trail of data wherever they go. Mobile applications leave an even richer data trail, since many of them are annotated…

The tricky interview questions on IoT explained in simple way

Mobile networks already deliver connectivity to a broad range of devices, enabling the development of innovative new services and applications.

Why IoT you need

This new wave of connectivity is going beyond tablets and laptops; to connected cars and buildings; TVs and game consoles; smart meters and traffic control; with the prospect of intelligently connecting almost anything and anyone.

This is what the GSMA refers to as the “Connected Life”. As the Connected Life evolves, the number of mobile connections worldwide is set to rise dramatically to reach 10.5 billion by 2020, while the total number of connected devices across all access technologies could reach 25.6 billion1 . These devices will bridge the physical and digital worlds, enabling a new category of services that improve the quality of life and productivity of individuals, society and enterprises. This Internet of Things - a widely distributed, locally intelligent network of smart devices - will enable extensions and enhance…

Applications in Focus in the age of Internet-of-Things

New types of applications can involve the electric vehicle and the smart house, in which appliances and services that provide notifications, security, energy-saving, automation, telecommunication, computers and entertainment are integrated into a single ecosystem with a shared user interface. Obviously, not everything will be in place straight away.

Developing the technology in Europe right now—demonstrating, testing and deploying products—it will be much nearer to implementing smart environments by 2020.

In the future computation, storage and communication services will be highly pervasive and distributed: people, smart objects, machines, platforms and the surrounding space (e.g., with wireless/wired sensors, M2M devices, RFID tags, etc.) will create a highly decentralized common pool of resources (up to the very edge of the “network”) interconnected by a dynamic network of networks. The “communication language” will be based on interoperable protocols, operating in heterogeneous en…
