What is OS Detection Tool?
Sometimes we want to know the operating system of a machine. When you know about the operating system accessing of system is easier as you can specifically search the internet for known security holes exists. Scan your system’s network to detect the OS type that will help you to see what a hacker will be able to see about your network. OS detection is a small tool that helps you to find and display your window version, type and whether its 32 bit or 64 bit.
Nmap performs multiple attempts to gather OS information if the attempts fail. By default it tries it 5 times but you can change this number. If you lower the value, you can speed up the scan, but you could eventually miss out on some information. On the other hand, raising this number will lead to slower but more sophisticated scans. But this is rarely done.
