Q. Whats the difference between Linux and Windows?
Would you highly reccomend Linux?
What are some of the features?

What are some of the features?
A. 1: Full access vs. no accessHaving access to the source code is probably the single most significant difference between Linux and Windows. The fact that Linux belongs to the GNU Public License ensures that users (of all sorts) can access (and alter) the code to the very kernel that serves as the foundation of the Linux operating system. You want to peer at the Windows code? Good luck. Unless you are a member of a very select (and elite, to many) group, you will never lay eyes on code making up the Windows operating system.
#2: Licensing freedom vs. licensing restrictionsAlong with access comes the difference between the licenses. Iâm sure that every IT professional could go on and on about licensing of PC software. But letâs just look at the key aspect of the licenses (without getting into legalese). With a Linux GPL-licensed operating system, you are free to modify that software and use and even republish or sell it (so long as you make the code available). Also, with the GPL, you can download a single copy of a Linux distribution (or application) and install it on as many machines as you like. With the Microsoft license, you can do none of the above. You are bound to the number of licenses you purchase, so if you purchase 10 licenses, you can legally install that operating system (or application) on only 10 machines.
#3: Online peer support vs. paid help-desk supportThis is one issue where most companies turn their backs on Linux. But itâs really not necessary. With Linux, you have the support of a huge community via forums, online search, and plenty of dedicated Web sites. And of course, if you feel the need, you can purchase support contracts from some of the bigger Linux companies (Red Hat and Novell for instance).
However, when you use the peer support inherent in Linux, you do fall prey to time.
On the other side of the coin is support for Windows.
#4: Full vs. partial hardware supportOne issue that is slowly becoming nonexistent is hardware support. Years ago, if you wanted to install Linux on a machine you had to make sure you hand-picked each piece of hardware or your installation would not work 100 percent. I can remember, back in 1997-ish, trying to figure out why I couldnât get Caldera Linux or Red Hat Linux to see my modem. After much looking around, I found I was the proud owner of a Winmodem. So I had to go out and purchase a US Robotics external modem because that was the one modem I knew would work. This is not so much the case now. You can grab a PC (or laptop) and most likely get one or more Linux distributions to install and work nearly 100 percent. But there are still some exceptions. For instance, hibernate/suspend remains a problem with many laptops, although it has come a long way.
With Windows, you know that most every piece of hardware will work with the operating system. Of course, there are times (and I have experienced this over and over) when you will wind up spending much of the day searching for the correct drivers for that piece of hardware you no longer have the install disk for. But you can go out and buy that 10-cent Ethernet card and know itâll work on your machine (so long as you have, or can find, the drivers). You also can rest assured that when you purchase that insanely powerful graphics card, you will probably be able to take full advantage of its power.
#5: Command line vs. no command lineNo matter how far the Linux operating system has come and how amazing the desktop environment becomes, the command line will always be an invaluable tool for administration purposes. Nothing will ever replace my favorite text-based editor, ssh, and any given command-line tool. I canât imagine administering a Linux machine without the command line. But for the end user â not so much. You could use a Linux machine for years and never touch the command line. Same with Windows. You can still use the command line with Windows, but not nearly to the extent as with Linux. And Microsoft tends to obfuscate the command prompt from users. Without going to Run and entering cmd (or command, or whichever it is these days), the user wonât even know the command-line tool exists. And if a user does get the Windows command line up and running, how useful is it really?
#6: Centralized vs. noncentralized application installationThe heading for this point might have thrown you for a loop. But letâs think about this for a second. With Linux you have (with nearly every distribution) a centralized location where you can search for, add, or remove software. Iâm talking about package management systems, such as Synaptic. With Synaptic, you can open up one tool, search for an application (or group of applications), and install that application without having to do any Web searching (or purchasing).
Windows has nothing like this. With Windows, you must know where to find the software you want to install, download the software (or put the CD into your machine), and run setup.exe o

How to treat tingling and numbness in foot due to Sciatica.?
Q.
A. you can try phDiagnosis and Treatment
Because of the many conditions that can compress nerve roots and cause sciatica, treatment options often differ from patient to patient. Treatment of the underlying cause of the compression is often the most effective course. When the cause is due to a prolapsed or lumbar disc herniation research has shown that with supportive treatment to help relieve pain 90% of disc prolapse will recover with no specific intervention. Genetics appear to influence the risk of developing disc herniation.
Imaging methods such as MRI neurography may help diagnosis and treatment of sciatica. MR neurography is a modified MRI technique using MRI software to provide better pictures of the spinal nerves and the effect of compression on these nerves. MR neurography may help diagnose piriformis syndrome which is another cause of sciatica that does not involve disc herniation. MR neurography is considered experimental and is not covered by insurances.
Most cases of sciatica can be effectively treated by physical therapy or massage therapy and appropriate changes in behavior and environment (for example cushioning, chair and desk height, exercise, stretching). Other conservative treatment options include anti-inflammatory medications (i.e. NSAIDs or oral steroids), pain medications, and epidural steroid injections (however the latter carries the risk of possible side effects and complications from the needle puncture and medications used).
"Alternative" and "complementary" treatments include chiropractic manipulation (although there is no scientific consensus for chiropractic's effectiveness) and somatics. Acupuncture has no effect beyond placebo in treating sciatica.

usb dont work for my laptop?
Q. for my laptop when i plug in a usb cable to it to load my portable hard drive it doesnt work and when u go to the desk top it load is there something wrong with my laptop usb ?and how do i fix it ?
A. The problem is your OS, you should try some GNU/Linux flavor, like LinuxMint.
Most GNU/Linux based OSes have very sophisticated software package management, which keeps track of installed software, resolves dependencies, verifies authenticity, resolves conflicts between packages, etc., relieving the user from those tasks, and providing an easy to manage and secure environment :), so things rarely broke, but if they do, it can be repaired without reinstallation.
When upgrading, you don't have to reboot it unless you're upgrading the kernel (which doesn't happen often), and even if you do, it doesn't keep bothering asking to rebot, you'll only see a ballon telling that and a icon change on the update manager, that's all :).
Also, in the case of a kernel incompatibility after a upgrade, you can always boot with the previous kernel, something not available on Windows, in fact, if you install a broken driver on Windows, the system can become unusable, and require a reinstallation.
