Therefore, the difference is not as the majority thinks it is related to fame but the reason is in several points:

System architecture: 

Linux architecture makes the latter protect itself from malware attacks and viruses. Routine permissions are difficult for malware to compromise and therefore can not cause real harm to the operating system. Linux and this refer to the system of powers in the latter. Where the power settings are divided into three main sections:

First: user privileges itself (User permission)

Second: Group Permission.

Third: Powers of other individuals who may or may not have direct access to the system (Everyone Else's Permission).

As a result, file permissions can also be divided into three types:

1) Read permission and symbolized by the letter r

2) Write permission and symbolized by the letter w

3) Execute permission and symbolized by the letter x

Therefore, even in the case of the congestion of a virus is harmful to the system remains subject to the authority of the user of the system, so for example in the smart phones running Android, many people get the powers of routines in their phones and this is dangerous for the security of their phones, because the Android system is built on Linux.
