Linux Story


Linus Torvalds

History

Linux was created by Linus Torvalds in the early 1990's he was inspired from Minix(A Unix like free operating system) which was created by Andrew Stuart Tanenbaum, Torvald's professor at University of Helsinki. Linus created Linux as a hobby project but it, later on, becomes one of the best Operating System and it is still growing.

Kernel

Linux kernel is the core of Linux operating system (The kernel is a computer program that is the core of a computer's operating system, with complete control over everything in the system) and it is based on UNIX. Linus designed Linux for his personal computer later on expanded to support a huge array of a computer. Linus Torvalds was heavily influenced by the GNU project in which his first kernel was released under the GPL-General Public Licence (GPL, the source code remain freely available to anyone who might want it).

Distributions

(based on Linux academy.com)
Linux has many distributions each has a Linux kernel, utilities and configuration. A full-blown Linux distribution consists of the following
  •  Linux Kernel: The core of a Linux operating system. From distributions to distributions there are changes in the Linux kernel specific for that distribution.
  • Core UNIX Tools: GNU toolset, X- windows GUI and other tools for critical disk and system resource management.
  • Supplemental Software: Additional software, such as a major server application, Desktop environments, productivity tools. Same for almost every distributions.
  • Startup Scripts: Used to start major operating system functions
  • Installers: Core feature in Linux distributions. Used for installing and managing software.

It is what the organizations do with the data matters. Big Data can be analyzed for insights that lead to a better decision and strategic business moves. An industrial analyst Doung Lancy explains Big Data as 3 V s Volume : Organizations collect data from a variety of sources, including business transactions and social media and information from a sensor or machine-to-machine data. In past storing, such large data was a problem but new technology like Hadoop have eased the burden Velocity : Data streams in at an unprecedented speed and must be dealt with in a timely manner. RFID tags, sensors, and smart metering are driving need to deal with torrents of data in near-real time. Variety :  Data comes in all type of formats, from structured, numeric in the traditional database to unstructured. text documents, em

Internet of Things (IoT)

Have you ever think of a world in which the devices around you are talking to you and between devices..! Imagine your music player turns on your favourite music based on your present mood or when you walk to the refrigerator it tells you what you can make with the stuff you already have in the refrigerator. Is this possible ?. These are possible with the help of IoT or Internet of Things . IoT applications are beyond our imagination. IoT or Internet of Things is a concept which comes to reality which describes the idea of interconnecting our everyday physical objects to the internet. How do this work? Sophisticated sensors ( a small chip that senses the surrounding activities ) and the actuators ( another small chip that responds to sensed activity ) are embedded inside the physical device around us collecting and transmitting valuable data. The devices can be your music system, Air Conditioner, Mobile phone etc which are securely communicating through an internet of t
