Memory management is the heart of operating systems; it is crucial for both programming and system administration. In the next few posts I'll cover memory with an eye towards practical aspects, but without shying away from internals. While the concepts are generic, examples are mostly from Linux...
在上面的例子中,Firefox使用了相当多的虚拟地址空间,因为它是传说中的吃内存大户。地址空间中的各个条带对应于不同的内存段(memory segment),如:堆、栈之类的。记住,这些段只是简单的内存地址范围,与Intel处理器的段没有关系。不管怎样,下面是一个Linux进程的标准的内存段布局: 当计算机开心、安全、可爱、正常的运...

Each process in a multi-tasking OS runs in its own memory sandbox.This sandbox is thevirtual address space, which in 32-bit mode isalways a 4GB block of memory addresses.These virtual addresses are mapped to physical memory bypage tables, which are maintained by the operating system kernel a...
