Why to use LINUX ?

There has been a surge of renewed interest in using Linux, in both the server and desktop spaces but still most of the people are scared of using linux.

                               In a majority of other operating systems, configuring your system so that it looks, acts and feels just the way you want it to isn’t always easy. For example, in Windows, say you wanted to have a taskbar at the top of the screen, but keep the start menu and such at the bottom. From what I have been able to tell, that isn’t possible yet. However, Linux’s two main rival desktop environments, GNOME and KDE, allow you to do this. Not only that, but you can have the clock on the left, in the middle, the program menus up there… The possibilities are endless. Also, configuring how pretty much every little detail looks is quite easy, I’ve found. Title bar buttons, scrollbars, screen savers (plenty of those), mouse cursors, login screens… A very long list.

1. The very basic thing is its Cost. It is freely available & u can download it free of cost from its individual websites. Whereas if u are preferring for windows & all, they will cost u at least 2000.00 rupees.
2. If u are good Linux use then it is very much powerful than other OS in all aspects except GUI.
3. The third important thing is Security; Linux is Open Source Software, while Windows is not. The simplest benefits of Open Source Code to demonstrate are increased security, reliability and functionality.
4. Virus, This reason is always at the top of my list. We all know kids are prone to opening and installing things they shouldn’t. Because you can’t watch your children 100 percent of the time, you can’t know where they’re getting those applications or attachments from. You can make sure those machines have antivirus and anti-spyware, but why even take the chance? When your kids are using the Linux operating system, this concern becomes moot.
5. Maintenance Cost, for companies & organizations, who use client server mechanism, they can save their maintenance cost up to 80% by switching to Linux.
6. It Doesn't Crash, Linux has proved to be so reliable and secure that it is commonly found in dedicated firewall and router systems used by high-profile companies to secure their networks. For more than ten years, it has not been uncommon for Linux systems to run for months or years without needing a single reboot.
7. Not Single Source Software - Linux is distributed by several companies, giving consumers to pick and choose the flavor that best suits their needs. Windows is the product of a single company, Microsoft Corporation. Windows users have no choice but to accept what Microsoft offers.                                                                                                                                        

One more good point to make here, you will end the constant late night computer assistance calls from your “buddy.” He calls because “you’re the computer pro, right?” When he telephones you next, tell him, “Sorry, I use Linux.” You’ll never hear from him again. Even better, he will now start calling someone else with Windows8 and bug them! The pleasures with Linux laptops are endless.

So howz linux? what u think?

Which Operating system is not Hacked Yet? ......That is mainframe

Hello friends,

The only operating System & server which is not hacked yet, & not possible  in feature also is MAINFRAME. That is why almost all the banks, Insurance companies, & those who are dealing with money, use to prefer mainframe only. That is the most secured server in the world. 

        As it is most secured. on the other hand it is very very much costly. In the survey it is found that banks spend nearly 70% of their expenditure on IT infrastructure.

                 Windows is an operating system started off as being meant for one user only, and they could run only one program at a time, and it was written to manage real devices in the PC, that is, it was limited to what the PC had.

                       When it was realised that this approach meant that programs which required more hardware capacity (like memory) could not be written, special routines that virtualised hardware had to be written. However, the underlying operating system files etc were all open to anyone who wanted to install software, that is, any programmer could overwrite system software causing malicious or unintended damage.The operating system grew organically and tries to mimic multi- user environment, virtualisation and allowing multiple programs at the same time etc, but this has been developed as additions and not designed from ground up. Hence the stability issues and issues of hacking because the entire system software etc was open for anybody to overwrite with their own code.

                                Mainframe OZ (zOS) on the other hand was written ground up to be virtual,multi user system, multi program system. The hardware was always virtualised and programmers do not deal with physical limitations of the system.

 Next, Operating system files and production code always was protected by the creation of a strict discipline and the creation of special libraries from which they could be run. This is controlled by system programmers.

          Application programs never replace operating system files unlike in Windows or UNIX (to a lesser extent).

         This created this environment never to be hacked to date.

                   If you want proof of this claim, consider what you can find by searching news archives and trade journals, looking for references to mainframes and data loss, hacking, security breaches, and similar topics. Recent research included checking the archives of ComputerWorld, InformationWeek, and The Wall Street Journal for reports of unauthorized access of any traditional mainframe environment via userid/ password exploitation, corruption of a mainframe-based networking resource, or contamination of a mainframe sys- tem software component.
