Talk about the interview and the idea of the last week (with plump panel)

A lot of small partners still in the public private messages asked me last week why suddenly no more, I also have in the public number promised that you will reply later. Well, let's just say it briefly.

In the past week, I mainly went out to find a job-the past week, noodles 4 companies, from small to large, and finally won 3 offer. After a struggle, I decided in Tuesday morning to choose the plump with relatively poor welfare benefits.

Mainly because plump's interviewer impressed me very much, I am delighted to be able to join a factory with so honest technical atmosphere.

So, since then, your lovely southern dust is a scholar, but also become a plump!!!

Relatively large companies, the face of the question may be more of a reference, so the southern dust on the interview last week plump and the United States to share the questions to everyone, may not be complete, some problems may be forgotten.

    Principle is: Based on the principle of locality, when the program is loaded, the part of the program can be loaded into memory, while remaining in the rest of the external memory, you can start the program execution, when the program executes, when the information that is accessed is not in memory, the part of the operating system needs to be transferred into memory, and then continue to execute the program The operating system then swap out the contents of the memory temporarily unused to external memory, freeing up space for the information to be transferred into memory.
