令在内存管理方面不得不说的 Linux is easily portable to most general-purpose 32-or 64-bit architectures as long as they have a paged memory management unit(PMMU) and a port of the GNU C compiler(gcc)(part of The GNU Compiler Collection, GCC). Linux has also been ported to a number of architectures without a Pmmu. although functionality is then obviously somewhat limited.

G GNU Operating System What is GNU? The GNU Project was launched in 1984 to develop a complete Unix-like operating system which is free software: the GNU System GNUs kernel wasn t finished. so GNu is used with the kerne Linux. The combination of gnu and linux is the gnuflinux operating system, now used by millions. (Sometimes this combination is incorrectly called Linux. There are many variants or"distributions" of GNU/Linux. We recommend the gnuflinux distributions that are 100% free Software, in other words, entirely freedom-respecting 2021/1/30 xlanchen: Linux Os Analysis 60 嵌入式系统实验室 EM日 EDDED SYSTEM LA日口 RATORY
