An operating system is a collection of programs written in low level languages that control the resources of a computer. It manages the computer's memory, processes, and all of its software and hardware. Operating system acts as an interface between the users and the hardware which allows the user to communicate with the computer without a language barrier. Booting is the process that occurs when users press the power button to turn the computer on. During this process, the computer runs tests to make sure everything is working correctly, checks for new hardware and then starts up the operating system by loading it into the main memory. The operating system ensures the best ...view middle of the document...
The history of 1960s disappointing efforts of IBM to develop OS/360 Operating System:
In April 1964, IBM introduced its new generation of mainframe computers, System/360. It was so named because it was aimed at full circle of customers, from business to science customers who did a lot of mathematical calculations as well as those who did simpler arithmetic on large sets of data.
CURRENT DEVELOPMENT OF WINDOWS AND LINUX
1. Microsoft Windows
In 2012, Windows 8 was introduced. It includes enhancements of the Windows desktop and streamlined file management. Windows 8 features a Start screen with tiles that connect to people, files, apps, and websites. Windows 8 has made the detection and correction of file system errors both more transparent and less intrusive.
Windows 8.1 is latest version update of Windows 8.Development of Windows 8.1(or Windows Blue) has been progressing at a decent pace with Build 2013 rapidly approaching. There is some minor changes that just makes sense. One of it is where Microsoft Windows has renamed the "Computer" on the left side of the File Explorer to “This PC” which would further clarify files and folders available on that specific PC, rather than the user having to open up a generic 'Computer' link. Besides that, there are certain improved features in the new Window 8.1 such as
a) Improved Boot Up Speed - better resource allocations to applications and the system by the technique of putting the system kernel to hibernate which acts as a resource manager.
b) Tiles-Based Interface - can be personalized and also display real-time information.
c) Windows-To-Go - allows users to make a copy of their OS complete with their settings into a USB flash drive. With this feature, users do not have to worry about the loss of data on their computer.
d) Windows Live Syncing - users can login on any Windows 8 computer with Live ID and get their personalized settings on it.
e) WinNc - file manager that enables direct drag-and-drop access to servers and network, view and edit files in the computer.
Windows 9 is in progress and it is expected to be launched in April 2015.Definetly this upcoming software is improved and much more user friendly.
2. Linux(Open Source Operating System )
It has been more than 20 years since Linus was found. Linus Torvalds, founder of Linux OS sparked an open source revolution with a short email declaring he was doing a new project “just for fun” and now Linux powers world’s super computers and other gadgets. Basically Linux is everywhere.
Linux kernel development proceeds under a loose, time-based release model, with a new major kernel release occurring every 2–3 months. This model, which was first formalized in 2005, gets new features into the mainline kernel and out to users with a minimum of delay. That, in turn, speeds the pace of development and minimizes the number of external changes that distributors
The latest Linux runs entirely on Chrome...
