The story about Linux is actually a battle between the two ends. In the cloud, the operating system has become a top player. While in the enterprise, Linux is eroded the exclusive territories of Unix systems, but if you want to talk about the operating system, still Microsoft's Windows in the enterprise dominate.

I. Introduction We often see some similar in the program disassembled code 0 × 32118965 this address, the operating system called linear address, or virtual address. What is the use of virtual address? Virtual address is how to translate into physical memory address? This chapter will give a brief account of this. 1.1 Linux Memory Addressing Overview Modern operating systems are in 32-bit protected mode. Each process can generally address 4G of physical space. But our physical memory is generally hundreds of M, the process can get 4 ...
