completely. I would like to explain here why. Please note that this is not a promotion meeting, nor a chapter that you must read when developing your own operating system. I just want to talk about my personal experience and hope to inspire you, at the same time, I want to explain why the second edition has such a change.I was already using Linux when I was writing the first version, but I didn't use much of it. I felt that I was not used to it. Now,

interference, less in and out of the kernel state consumption, but not a good use of multi-core CPU, the current Linux pthread generally do so.Thread implementations can be divided into two categories: User-level threads (user-level thread) and kernel thread threads (kernel-level thread), which are also known as kernel-supported threads or lightweight processes. In multi-threaded operating system, the implementation of each system is not the same, in

Compared with other operating systems, the Linux desktop environment has advantages and disadvantages, but Linux is ready to enter the personal computer, and this advanced operating system will no longer be the exclusive of geeks. The latest graphic improvements indicate that the linux operating system can reach a new

Introduction to operating systems A computer system can receive and store information according to human requirements. It can process and provide the required results. The results (output information) depend on the received information (input information) and corresponding processing methods. 1. Learning Process: I used to learn some related operating system know

Simply put, x86 represents a 32-bit operating system x64 represents a 64-bit operating system. If your CPU is more than two cores, it certainly supports 64-bit operating systems. If your computer has more than 4G of memory, it will use a 64-bit system, because 32-bit Windows 7 or Vista, the largest only support 3.25G o

handle multiple tasks, not necessarily at the same time. The key to parallelism is the ability to handle multiple tasks at the same time.5. Synchronous and asynchronousSynchronization means that when a process executes a request, if it takes a while for the request to return the information, the process waits until the return message is received, and the process does not need to wait all the time, but continues to perform the following operations, regardless of the state of the other process.
