Linux and Windows are often compared with one another, being both computer operating systems. Apparently this cannot be helped since Windows is the most prominent operating system released under a proprietary software license while Linux is its equivalent in prominence under a free software license. They have found themselves competing for user-base in the personal computer market as well as the server market.
Each has its own philosophy and differs in cost, ease of use, versatility, stability and their perceived weak areas. Windows tend to dominate the desktop and personal computer markets while Linux captures a large share of the web server, render farm and supercomputer markets. Their differences may probably be the reason why both continue to exist in spite of the other.
