Linux can be installed on a variety of computer hardware devices, such as mobile phones, tablets, routers, desktops, mainframes, supercomputers, and so on.

2 , Linux What can I do?

because Linux is easy to access, and cheap, most of the servers are now using Linux systems, also can be used on our personal computers, now the core of the Android smartphone is also using Linux . Routers in our network are also using Linux, andLinux uses a wide range of applications.

Do servers (websites, games, storage), etc.

Pc

Cell phone

Access control system

ATM Teller Machines

Router

Intelligent terminal
