I,
For me, the best thing about Linux is that it is not only an operating system with huge ecosystem support, but also can be easily implemented by embedded. The combination of the two creates infinite possibilities.
Compared with the development method of single-chip microcomputer that has to be written from scratch, if you want to use any peripherals now, as long as there is a driver, it can be used to connect, and what software you want to use is the same.
This is exactly the significance of Beaglebone, Raspberry Pi, cubieboard, and other open-source hardware.
II,
On the surface, I learned about Linux. I actually learned about computer components, network technology, operating system principles, and Script Programming ......
I always think that Linux is used to "work", rather than surfing the Internet, reading documents, and playing games. Therefore, learning Linux is not as simple as learning Windows. In the Windows world, it can be used very well without understanding the above knowledge. But in Linux, it is as hard to understand this knowledge without legs.
