One of the greatest programmers, Donald Knuth, describes programming not as telling a computer how to do something, but telling a person how they would instruct a computer to do something.
In our case, the kernel is Linux. Now, the kernel all by itself won't do anything. You can't even boot up a computer with just a kernel. Think of the kernel as the water pipes for a house. Without the pipes, the faucets won't work, but the pipes are pretty useless if there are no faucets. Together, the users applications (from the GNU project and other places) and the kernel (Linux) make up the entire operating system, GNU/Linux. (查看原文)
Source code is the human-readable form of a program. In order to transform it into a program that a computer can run, we need to assemble and link it.
The first step is to assemble it. Assembling is the process that transforms what you typed into instructions for the machine. The machine itself only reads sets of numbers, but humans prefer words. An assembly language is a more human-readable form of the instructions a computer understands. Assemble transforms the human-readable file into a machine-readable one.To assemble the program type in the command
as exit.s -o exit.o
as is the command which runs the assembler, exit.sis the source file, and-o
