Lniux release, Gun:gun/linux.
Source code: Must be compiled to run, so the release is already the source code has been compiled to complete the things, together, formed a release version.
Fedora: It's a desktop version for Redhat, which is mostly used for enterprise testing.

The three major distribution editions of the mainstream

Release version
1.Redhat (Centos)
2.SUSE (the best-looking Enterprise Edition is SUSE)
3.Debian (Ubuntu is the Debian distribution, Mint) the most difficult to use, to make the least limit, the master use.

Gentoo
LFS (Linux from scratch starting line) Strictly speaking, LFS is not a distribution, but a book.
teach you to compile Linux and find software components. There are not many people on the market who play LFS, if you can this, you can fully understand the Linux ~

Question: What does compilation mean?

Compiling the source code into binary code that can be executed on the CPU
The Redhat release is already compiled and is compiled in a common format (compiled on older CPUs, compatible with older versions).
If we want to play the performance of a program, on this platform, such as the Redhat on the compilation, on this platform to install the configuration. Will play a better role in program performance
So compile and compile their own good, the advantage is that you can better play the CPU features, but also more trouble, time is longer, and compiled good, is relatively simple.

such as product development
. Java is the source code, and after compiling, the suffix becomes. class.
The. class file is not directly editable
Different development languages, the source code is a non-pass suffix, for example, C language is. C
