The term "core operating system" can be especially often hear from fans POSIX-systems. However, you can see, this does not mean that the same, for example, Windows, the kernel does not as such. What is the operating system kernel? What are they for? What are the nucleus of different OS? Here's to these questions we are with you and try to find answers.Why kernel?It would be logical to assume that

Following are a few basic questions that cover the essentials of OS:1. Explain the concept of Reentrancy.It is a useful, memory-saving technique for multiprogrammed timesharing systems. A Reentrant Procedure is one in which multiple users can share a single copy of a program during the same period. Reentrancy has 2 key aspects: The program code cannot modify itself, and the local data for eac
UNIX AirwaysEveryone brings one piece of the plane along when they come to the airport. They all go out on the runway and put the plane together piece by piece, arguing non-stop about what kind of plane they are supposed to be building.Air DOSEverybody pushes the airplane until it glides, then they jump on and let the plane coast until it hits the ground again. Then they push again, jump on again,
Most books on operating systems deal with theory while ignoring practice. While the usual principles are covered in detail, the book describes a small, but real UNIX-like operating system: MINIX. The book demonstrates how it works while illustrating the principles behind it. Operating Systems: Design and Implementation Second Edition provides the MINIX source code. The relevant selections of the M
There are plenty of opinions out there about Windows, Mac, Linux, Unix, and Solaris. Everyone knows that Windows is by far the most dominant OS for both business and personal use. It's what I use for business, and my own personal development. In my opinion, Windows XP is the best operating system out there.
Many Microsoft users are totally 100% pro-Windows, and scoff at the very mention of Mac
Operating systems seem to have received more attention these days than they have ever before, and while there are numerous available discussion points, in relation to new versions of these operating systems, one of the biggest trends that has been fascinating to watch is how people are switching operating systems like crazy.

Microsoft's Vista: New Horizon or the End of the Road for PC Operating Systems?After Microsoft announced on May 3 that it will drop its $44.6 billion bid to acquire Yahoo, many -- including experts at Wharton -- declared the decision to be a smart move. Microsoft, they say, has more pressing issues, including the need to make its flagship operating system Vista more popular among customers as it c

In my opinion Microsoft is a lot better at making money than it is at making good operating systems.
We all know Linux is great…it does infinite loops in 5 seconds. People will realize that software is not a product; you use it to build a product. When it comes to software, I much prefer free [...]

There is a common aspect in webhosts that webmasters look for: the best bang for the buck. Webmasters don’t want to spend too much money, but then again, they also want the functionality that the professionals use. Two vastly popular types of management systems are being in use today: cPanel and Virtuozzo.

Sam Harnett Operating Systems: File Systems File systems are an integral part of any operating systems with the capacity for long term storage. There are two distinct parts of a file system, the mechanism for storing files and the directory structure into which they are organised. In mordern operating systems where it is possibe for several user to access the same files simultaneously it has also become necessary for such features as access control and different forms of file protection to be implemented . A file is a collection of binary data. A file could represent a program, a document or in some cases part of the file system itself. In modern computing it is quite common for their to be several different storage devices attached to the same computer. A common data structure such as
Run virtual machines on your Windows or Linux PC with VMware Player 2.0.

Microsoft Windows server operating systems simplify managing the amount of network storage space users receive. Here's how to set warning messages and disk quotas using both the Windows Server 2003 and Windows Small Business Server 2003 operating systems. Running out of server disk space is one of those problems that just shouldn't happen. Yet, with so many organizations increasingly trying to do more with less, having to monitor security, guard against spyware, viruses and network intrusions and manage other administrative challenges, an administrator's workday is quickly consumed. Fortunately, newer Windows server operating systems simplify managing the amount of network storage space users receive. Here’s how to set warning messages and disk quotas using both the Windows Server 2003 and Windows Small Business Server 2003 operating systems. Windows Small Business Server 2003 To configure disk quota warnings and limitations for an individual user in Windows Small Business

But largely in the computing world, there are the Big Three, with Microsoft leading the pack, Apple making a strong second, and Linux coming up from the rear. On the server side, Solaris and BSD have some light numbers (though they’re adapting to the desktop presently). But when you want to establish yourself as UBER-leet, check out one of these arcane systems and you will forever have bragging rights as one who ventured far off the beaten path.
Plan 9 From Bell Labs - What a tangled history it has! Created by the same visionaries who made Unix, this was an experimental venture to try to re-define the multi-tasking system. Bell Labs orphaned the project and then sold the lab out to Lucent technologies, which killed it completely. If it hadn’t been released as open source, it would be dead today, but instead it has a very tiny cultish following. Arcane in the extreme, it doesn&r
By Tonami PlaymanOver the years operating systems have been raising their standard in graphics so much that to run a current OS like windows vista, you need a hardware bolstering a minimum of 512mb - 1 GB of RAM. Such requirements are extremely high and limited to only a few.Yes most hardware has gotten faster and cheaper, following Moore's law well, but the software keep getting heavier with every new generation agreeing with Gate's law. This is all good progress if we just want to stick with business as usual. Every competitor in the computer industry are tied up in a power struggle, with each one vying for the most sales by offering more and more of speed and overloading graphics.I see this as a blind trail, because no one pauses to asses the situation. What if we take a new look at the way we think we want our software and hardware to be. The One laptop per Child program initiated by Nicholas Negroponte has shed some light on what could be done with the PC. It was designed for
