It is an operating system that supports multi-user, multi-tasking, multi-threading and multi-CPU. It can run major UNIX software tools, applications and network contracts. It supports 32-bit and 64-bit hardware. Linux inherits the network-centric design philosophy of Unix and is a multi-user network operating system with stable performance.

Linux advantages:

1 High security - Unless the user logs in as root under Linux system, it is difficult for the program to modify the system settings and configuration. For this reason, the downloaded files/malware will have restricted permissions.

2 High availability - Linux is very stable and not easy to crash.
