Why linux os better than windos os?


         Linux is an open-source Operating System. People can change codes and add programs to Linux OS which will help use your computer better. Linux evolved as a reaction to the monopoly position of windows. you can't change any code for windows OS. You can't even see which processes in windows. Linux user's can edit its OS and design new OS.


All flavors of Windows come from Microsoft. Linux come from different companies like LIndows , Lycoris, Red Hat, SuSe, Mandrake, Knopping, Slackware.The most important thing is Linux is freely available for desktop or home use but Windows is expensive.

Linux And Windows Top 5 Os Distribution:


Top 5 linux os distribution:
  1. Ubuntu.
  2. Debian.
  3. Fedora.
  4. CentOS.
  5. Red Hat.

Top 5 windows os distribution:
  1. Windows 95.
  2. Windows XP.
  3. Windows 98.
  4. Windows 7.
  5. Windows Millennium Edition. 

Lets us see the major 10 reasons linux is best..:


1. Software repositories

Having all the software you need in one place saves you having to trawl the web to find the program you're missing. It also means the software has been independently checked and digitally signed by the distro's developers, making it almost impossible to pick up a root-kitted version.



2. Powerful shell

While some criticise Linux for its use of the shell, this really is a powerful advantage. Easy GUIs are good, and we need to be able to carry out standard administration and configuration tasks using a GUI, but sometimes a shell can be so much faster and more flexible, unlike a DOS box.


3. Multiple desktops

Have you ever watched a Windows user trying to juggle several programs and windows on screen at once, assuming they have enough resources to run several programs? Multiple desktops makes it easy to have many programs and windows open all at once, but only have to deal with the ones you are using right now.
For example, you could have your email and internet on one desktop, a game on another, and the work you're supposed to be doing on another. A flick of the mouse is all that's required to switch between them.


4. Drivers included

Some claim that Windows 7 supports more hardware than Linux. In fact, the reverse is true. Windows 7 supports very little hardware – most hardware requires you to install drivers from the manufacturer.
On the other hand, the majority of hardware is supported directly by the Linux kernel, so you can just plug and play – this is one of the reasons live CDs work so well.


5. Runs on any platform

Linux runs on just about any hardware you can name, from mobile phones to supercomputers. The open source nature of the kernel and software means it can be ported to another architecture by a third party if the existing developers see no need. The end user doesn't need to care about the underlying hardware.


6. Security

Linux is inherently more secure than Windows, because security is a feature of the core system, not a boltedon afterthought. With a firewall at the heart of the kernel and the virtual impossibility of slipping malware into the software repositories, a Linux computer can devote all its resources to running your programs, rather than being bogged down with security programs running all the time.


7. Lack of malware


Malware is virtually unheard of on Linux. This is mainly down to the open source nature of the software. If you install from your distro's repositories, you know the software has been checked by them.


8. Thousands of programs included

A Linux distro is not just an operating system; it comes with thousands of free applications. While other systems consider a desktop, web browser and mailer to be all you need, a typical Linux distro includes everything you could possibly want: internet tools, office software, multimedia and games. If it's not on the installation disc, there are thousands more available for download.


9. No reinstallations

When problems occur in Linux, they can be fixed directly. You don't even need to reinstall when you want to update to the latest version of your distro.

10.Server Security

Linux and open-source applications are popular in the Internet-facing extranet of the enterprise, Cox notes. And Linux has become a kind of industrial technology for vendors which use it in a wide range of products and services — for instance Amazon's EC2 computing environment data centers rely on Xen-based Linux servers.

Apple's iphone 5



        The iPhone 5 is real and nearly ready to ship and we got a bit of hands-on time with it today. The new phone is just a bit longer than the current iPhone 4S and far speedier. Maps and photos flew by and the various apps popped up in a few seconds.
It’s not as earth-shatteringly different than the iPhone 4S, to be sure. While the real benchmarks and games aren’t quite available yet, folks who haven’t used the 4S will notice a bump.
The screen is the real draw here and I’m really interested to see how it improves the experience in real-world conditions. Obviously you’re getting just a bit more real estate and the Lightning connector allows for far more room for battery and processor. Again, it’s far too early to tell right now, but if you’re looking for something in the sweet spot between monsters like the Galaxy S III and the arguably bordering-on-too-small (at this point) iPhone 4, this may be a good compromise.


Build quality is quite nice and the solid aluminum is quite unique and quite solid. Hopefully this will reduce some damage if it falls on a hard surface.

The iPhone 5 will be available in both black and white at the same price points as the previous generation: $199 for the 16GB model, $299 for the 32GB version and $399 for the 64GB variant.




We’ll know far more about these phones when we get to really use them later this month but until then I can report that this is a solid and interesting improvement to a solid and interesting phone. Is it a blockbuster launch? Probably not, but it is an interstitial launch that allows Apple to update the screen size and dock connector while still hiding some tricks up its sleeve.
