Operating System :: OS Technology

The Operating System / OS is the core of your computing experience. There’s no point trying to run a fully legal setup if the base of it is illegal. Windows and Mac OS are the most known operating systems, however they aren’t free. But Ubuntu is one of the free Operating System as well as lots of users using this OS – Ubuntu.

Operating System OS

An operating system is a program that manages a computer’s hardware. It also provides a basis for application programs and acts as an intermediary between the computer user and the computer hardware.

Operating System

  • Manages the operations of the CPU
  • Controls the I/O and storage resources and the activities of the computer
  • provides various support services while executing user programs
  • Primary purpose is to maximize the productivity of the computer system by operating it in the most efficient manner etc.

Types of Operating System

Different types of Operating System such as like they are Windows NT, Windows 98, Windows 2000, XP (Released October 2001 ), Windows 8, Windows 10 Professional, MAC OS, red-hat Linux, UBUNTU, Open BSDN.

Microsoft .Net framework Why Use..It

People ask me why using Microsoft .Net framework for PC, Notebook, Tab…  exactly,

Microsoft .Net Framework Managed Extensibility Framework, Windows Communication Foundation, Windows Workflow Foundation, and Windows Identity Foundation of your Desktop / Notebook System.

The .NET Framework 4.5.2 enables out-of-process, Event Tracing for Windows (ETW) – based activity tracing for a larger surface area. This enables Application Performance Management vendors to provide lightweight tools that accurately track the costs of individual requests and activities that cross threads.

Microsoft .NET Framework 4.5.2 Developer Pack absolutely use for better job processing for different service pack SP; such as Windows Vista SP2, Windows 7 SP1, Windows 8, Windows 8.1, Windows Server 2008 SP2 Windows Server 2008 R2 SP1, Windows Server 2012 and Windows Server 2012 R2.

Windows 10 “Represents the first step of a whole New Generation of Windows

Windows 10 “represents the first step of a whole new generation of Windows,” writes Terry Myerson, executive vice president, Operating Systems, in a blog post. “Windows 10 unlocks new experiences for customers to work, play and connect. Windows 10 embodies what our customers (both consumers and enterprises) demand and what we will deliver.” 

Windows 10 will run across an incredibly broad set of devices – from the Internet of Things, to servers in enterprise datacenters worldwide.

“ Some of these devices have 4-inch screens – some have 80-inch screens – and some don’t have screens at all,”

he writes. “Some of these devices you hold in your hand, others are 10 feet away. Some of these devices you primarily use touch/pen, others mouse/keyboard, others controller/gesture – and some devices can switch between input types.”

We’re not talking about one user interface to rule them all, he writes. “We’re talking about one product family, with a tailored experience for each device.”

Windows 10 will be “ built from the ground-up for a mobile-first, cloud-first world. This new Windows must help our customers be productive in both their digital work and their digital life. This new Windows must empower people and organizations to do great things.”

Windows 10 will “deliver the right experience on the right device at the right time. It will be our most comprehensive platform ever.”

Technical preview PC productivity

The early technical preview of Windows 10 demonstrates new levels of flexibility, navigation and familiarity through the Windows experience. Features include these:

  • Expanded Start menu. The familiar Start menu is back, providing quick one-click access to the functions and files that people use most, and it includes a new space to personalize with favorite apps, programs, people and websites.
  • Apps that run in a window. Apps from the Windows Store now open in the same format that desktop programs do. They can be resized and moved around, and have title bars at the top allowing users to maximize, minimize and close with a click.
  • Snap enhancements. Working in multiple apps at once is easier and more intuitive with snap improvements. A new quadrant layout allows up to four apps to be snapped on the same screen. Windows will also show other apps and programs running for additional snapping, and it will even make smart suggestions on filling available screen space with other open apps.
  • New Task view button. The new Task view button on the task bar enables one view for all open apps and files, allowing for quick switching and one-touch access to any desktop created.
  • Multiple desktops. Instead of too many apps and files overlapping on a single desktop, it’s easy to create and switch between distinct desktops for different purposes and projects — whether for work or personal use.

Google Chromebook and Google Chrome OS

Google brings Chromebook or Google Chrome OS – Operating System – with one or two other people will be happy to download the latest Chrome OS update.

Chrome OS update brings multiple user log-ins

The new version adds in Multi Sign-in support that makes logging on with one of a handful of different accounts a breeze. On top of that, there’s a new “App Info” view in the launcher, settings now appear in a window rather than a tab, managed bookmarks and the ability to save to Google Drive from Incognito mode.

What is UNIX |

UNIX is an operating system which was first developed in the 1960s, and has been under constant development ever since. By operating system, we mean the suite of programs which make the computer work. It is a stable, multi-user, multi-tasking system for servers, desktops and laptops.

UNIX systems also have a graphical user interface (GUI) similar to Microsoft Windows which provides an easy to use environment. However, knowledge of UNIX is required for operations, which aren’t covered by a graphical program, or for when there is no windows interface available, for example, in a telnet session.

Types of UNIX
There are many different versions of UNIX, although they share common similarities. The most popular varieties of UNIX are Sun Solaris, GNU/Linux, and MacOS X. Solaris on our servers and workstations, and Fedora Linux on the servers and desktop PCs.

The UNIX operating system is made up of three parts; the kernel, the shell and the programs.

Linux OS :: Operating System

Linux is an operating system developed by Linus Torvalds under the free and open-source development and distribution. Linux is often seen as the champion of the open-source cause, being, perhaps, the most well-known example of open-source collaboration second only to Mozilla Firefox.

Linux comes with various distributions, better known as “distros”. In layman’s terms, distros are different versions of operating systems based on the Linux kernel. Linux distros have taken on a variety of forms: from desktop computing to mobile phones and everything in between and beyond. Yes, that means motorised rickshaws can run Linux as well.

For beginners, the distro of choice is Ubuntu. It’s the easiest to set up and perfect for learning the ropes if you’re new to the world of Linux. Is it the best distro? Well that is up to you and your needs. But if it comes to learning how the entire eco-system of Linux works, Ubuntu is the best starting point.

Other distros for desktop environments worth checking out are Kubuntu, Mint, Fedora and Debian.
Laptop and older system users would do well to try out Crunchbang, Bodhi Linux and Puppy Linux since they are minimalist OSs designed to use low system resources. If you’re not too keen on changing from Mac or Windows, Pear Linux and ZorinOS can make the change to Linux easier with user interfaces that resemble Mac and Windows respectively.

It might be a tad overwhelming to install Linux on a system for someone who hasn’t dabbled into their computer’s ins and outs once in a while, but the installation process is pretty straightforward.
1.    Download Ubuntu from the following link:
I recommend downloading Ubuntu 12.04 LTS for a more stable, hassle-free version of the OS.
2.    You can install Ubuntu by booting from a DVD after burning the .iso image onto a disc, but booting from USB is easier. You need to download and install Pendrive Linux’s USB Installer for that. (
3.    After you’re done with successfully burning the ISO image to the USB, restart your computer. It should boot automatically from the USB, but if it doesn’t press F12 on the boot menu and rearrange the boot order by moving your USB to the top.

Note: You should backup ALL your data to a large number of USBs or an external hard drive before you install, or reinstall, any operating system.


Linux’s open-source nature is a coin toss. On one hand it means, many commercial software like Microsoft Office or Photoshop won’t work. But on the flipside, there are more than enough able open-source alternatives.

WeBInOS || New Operating System
