OS (Operating System) Fingerprinting is a process to find out victim’s Operating
System(Windows, Linux, UNIX)

Your reaction to discovering a printer may be very different than to finding a router, wireless access point, telephone PBX, game console, Windows desktop, or Unix server.

Finer grained detection (such as distinguishing Mac OS X 10.4 from 10.3) is useful for determining vulnerability to specific flaws and for tailoring effective exploits for those vulnerabilities.
