Operating Systems

Devices that record precise results require a real-time operating system. This is the same kind of operating system needed for a device hat performs regimented tasks.

it really behaves like a lock on an ordinary door in the real world: You enter a room, you lock the door because you do not want to be disturbed, do whatever you need to do in there, unlock the door and only then can somebody else enter. If anybody tries to enter the room while you are still in there, he has to wait. As long as you do not forget to lock or unlock the door, this algorithms guarantees mutual exclusion and protects the so called critical region. And this is what the whole thing would look like using a parallel programming system

I install aVast Anti-virus & I install FireFox & adobe Flash & reader then I check for windows updates.

Most definitely, this is called booting. In the old days (of mainframes), it was called IPL (for Initial Program Load).

Much better, safer, and faster than Windows.

Unix was designed specifically to handle many users and requests at the same time (time-sharing).

The mouse environment result of clicking on and dragging the visualisation (icon) of a file on a screen from one place to another results in the file being renamed (the full file name from "root").

You'll have to be a bit more specific. What are you trying to patch? Also, KDE 2 hasn't seen any sort of development since 2001, and even KDE 3.5 is only in maintenance mode. KDE 4.2 is the latest release (as of April 2009).

If you are looking for a ready-built FreeBSD system with KDE, try PC-BSD or DesktopBSD.

Yes, a computer operating system can be downloaded onto your computer. One of the most common file formats to download operating systems is the .img file format. The .img file format can be used by programs like Oracle's VirtualBox, to create a virtual computer on your own computer. This uses the operating system that is saved in the .img file without overriding your current computers operating system and basically creates another "fake" or virtual computer within your own computer. However, these operating systems can also be used to replace your current operating system or to dual boot your computer, this means to have two operating systems installed on one computer at the same time. Operating systems can also be downloaded for the sole purpose of replacing your current operating system. For example, when a person upgrades their computer from running Windows 8.1 to Windows 10, they are essentially downloading a new operating system on to their computer from Microsoft, but in a way that it completely replaces their current operating system.

An absolute pathname, is the location of a filesystem object relative to the root directory.

absolute pathnames always begin with a slash (/).

With Absolute pathname you have access to complete file system objects such as directories and files.

The concept of providing pensions for retired employees did not begin until the nineteenth century in Europe and did not significantly spread to the United States until the early twentieth century

All operating systems manage system resources.

Depending on the environment that the Operating System will work in (e.g. will it work in a lab or an office?) the way the user interacts with it is important.

A graphical user interface (GUI) is much better than a Command Line Interface (CLI) for office workers as they are already familiar with it and little training is needed on the work places part.

A CLI is useful for running tests in a lab or processing data where training has already given. A CLI is a no-frill operating system (e.g. no images etc.)

Universal banks are able to take on a large number of functions because they are both a commercial bank and investment bank. Additionally, universal banks provide other financial services such as accounting, insurance, fund investment, and issuing of credit cards.

Windows is an operating system developed by Microsoft. Apple makes Macintosh computers that run Apple's own Mac OS X operating system but can also run the Windows operating system.
