top 7 linux distributions

SCREENSHOT

Microsoft proves that seven is indeed a lucky and magical number. It would be too, for a company which decided to skip a version 13 for their Office suite to avoid bad luck.

Despite the criticism and negative publicity, Windows Vista was a significant Windows release, and a step forward in the evolution of the Windows operating system.Windows 7 is a marked improvement over Vista all around, and its new features and improvemnts make it a strong competitor for Windows XP as well.

Ironically, Windows 7, isn’t even Windows 7.0! It runs a slightly improved kernel of Windows Vista with a version number of 6.1 much like Windows XP ran an improved Windows 2000 kernel with a version of 5.1 (Windows 2000 was 5.0). However as Microsoft has painfully pointed out on several occasions, this makes Windows 7 no less significant.

Windows 7 will support both 32-bit and 64-bit systems. The bare minimum requirements for the 32-bit include a 1GHz processor, 1GB RAM, 16GB available hard-disk space, and a DirectX 9 graphics device with WDDM 1.0 or higher driver. 64-bit systems will require at least a 1 GHz processor, 2GB RAM, 20GB of free space on your hard drive, and a DirectX 9 graphics device with WDDM 1.0 or higher driver. A touch-screen monitor is required to take advantage of the native touch features. Do note that some users have claimed to have limited success running the Windows 7 beta with less than 1GB of RAM, but that’s not recommended.

What’s Good
Windows 7 is the biggest step forward in usability since Windows 95. In fact, over half of what makes it better than Vista boils down to user interface improvements and enhancements, not so much actual new features.

Its fancy new user interface—the heart of which is Aero Peek, making every open window transparent except the one you’re focusing on at the moment so you can find what you’re looking for—actually changes the way you use Windows. It breaks the instinct to maximize windows as you’re using them; instead, you simply let windows hang out, since it’s much easier to juggle them. In other words, it radically reorients the UI around multitasking. After six months of using Aero Peek and the new launcher taskbar, going back to Vista’s taskbar, digging through collapsed app bars, or even its Peek-less Alt+Tab feels barbaric and primitive. I wouldn’t mind an Mac OS Exposé ripoff to complete the multitasking triumph, though.

Windows 7 brings back a sense of a tightness and control that was sometimes missing in Vista—there’s a techincal reason for this relating in part to the way graphics are handled—moments where I’ve felt like I wasn’t in control of my PC have been few and far between, even during the beta and release candidate periods. The more chaste User Account Control goes to that—the frequency with which it interrupts you was grating in Vista, like standing under a dripping faucet. But it actually works as Microsoft intended now, with more security, since you’re less likely to repeatedly hammer “OK” to anything that pops up, just so it leaves you the hell alone.

Other super welcome improvements are faster, more logical search—in the Music folder for instance, you can narrow by artist, genre or album—and more excellent file previews, though they’re not quite as awesome as what OS X offers up. (And why aren’t they on by default?) There are lots of little things that make you say, “finally” or “that’s great,” like legit codec support baked in to Windows Media Player, Device Stage when you plug in your gadgets, or the retardiculously awesome background images.

In short, Windows 7 is what Windows should feel like in 2009.

1.U torrent

U torrent is the most popular and efficient bit torrent client available today.  uTorrent has all the functions a torrent downloader will ever need, and it only requires 1 MB of  memory.It has better seeding and downloading options and better interface.

2.Vuze

Even though vuze has better options and   settings  than the counterparts it takes more CPU space and not so advisable.One of the best features about Vuze is the  availability of various cool plugins and add-on features.it has options for  managing  multiple downloads simultaneously from a single GUI window, detailed real-time download status and info with export to XML, advanced download and seeding management rules etc

3.Bit torrent

It was written in python by Bram Cohen, who invented and developed the BitTorrent file-sharing protocol.cross-platform, with builds for Windows, Mac OS X, Unix and Linux. Bandwidth management, queuing and network optimization features are all excellent and easy to use.However compared to the counterparts it has no plug-in support, no advanced file management within torrents, no pretty 3-D visualizations and so not popular like u torrent or vuze.

1. OpenVZ is an operating system-level virtualization technology based on the Linux kernel and operating system.It can take care of more than one os at a tim e like other virtualization technologies.
2. 
3. VirtualBox is an x86 virtualization environment , made by  Sun Microsystems as part of its Sun xVM virtualization platform. A lot of  host operating systems like Linux, Mac OS X, OS/2 Warp, Windows XP or Vista, and Solaris, are supported in this. Supported guest operating systems include FreeBSD, Linux, OpenBSD, OS/2 Warp,linux Kernal 2.4/2.6, Windows and Solaris.It is great for home use and for testing programs which may other wise interfere with the os.
4. 
5. Kernel-based Virtual Machine (KVM) is a Linux kernel virtualization infrastructure. KVM currently supports native virtualization using Intel VT or AMD-V. A wide variety of guest operating systems work with KVM, including many flavours of Linux, BSD, Solaris, and Windows etc. KVM is included with Debian, OpenSuse and other Linux distributions.
6. Xen is a virtual machine monitor for 32 / 64 bit Intel / AMD (IA 64) and PowerPC 970 architectures. systems to be executed on the same . XEN is included with most popular Linux distributions such as Debian, Ubuntu, CentOS, RHEL, Fedora and many others.It is very pleasant in its appeaance and easy to work with.It supports running several machines at the same time.
7. 
8. Linux-VServer is a VPN  implementation done by adding operating system-level virtualization  to the Linux kernel making it an integral part of the operating system.
9. 
   User Mode Linux (UML) was the first virtualization technology that was available  for the Linux Operating system.It has less performance and stability compared with others . Coming version support for x86 virtualization to UML may reduce this disadvantages.
10. VMWare is one of the leaders of virtualization technologies.It has extended to linux platforms .It is known for its advanced features.But a hefty price tag always follows.
