开发接口标准

ABI

    Application  binary  interface,应用程序核和操作系统之间的底层接口,涉及到 strace这个命令,系统调用

API

    Application programming interface,源代码和库之间的接口。开发关心这个多些,运维遇到想甩锅给你的开发学学还是有必要。涉及到的命令是 ltrace,库调用

POSIX

    Portable Operating System Interface X 是凑数的

    IEEE在操作系统上一系列API标准

运行程序格式

    Windows:.exe,dll(dynamic link library),lib

    Linux:ELF,so(share object),a

Linux内核

涉及命令
uname -r
lsb_release(6版本)

3.10.0-693.el7

3是指主版本号,系统变动大才会修改这个
10是指次版本号,一般有新功能这个才会变
0是指出现一些bug,纠正后这个就会变
693是指打包修订次数
el7这个是红帽厂商写的些东西,不清楚什么用途

开源协议

GPL最严格,MIT最宽松
