*/ Write Efficiency test results:After adding a custom buffer, the test found that its efficiency was 100 times faster than the non-self-defined buffer, and that the write rate of the marked C was several multiples faster. If the buffer size is appropriate, its efficiency will increase even more. So when we change Buf_szie to a larger value (buf_szie=50000), after recompiling, the test results are as follows:This efficiency is improved, so choosing a suitable buffer is especially import
Operating System Concepts Learning note 15 memory management (i) backgroundMemory is the center of modern computer operation. Memory has a very big group of words or bytes, and each word or byte has its own address. The CPU extracts instructions from memory based on the value of the program counter (PC), which can cause further reads and writes to a specific memory address.A typical instruction execution cy

I like to work based on web apps. It is very attractive to implement an application that can be run from anywhere and on any device. Over the past few months, I've been trying to get some basic lightweight machine learning algorithms that run on JavaScript and then use them to build " smart " Web apps. With the advent of node, it is possible to train the model on the server side and then use these models to make predictions on the client. I've researc

is the Lyx/texmacs is not necessarily bad. For a software engineering similar to the computer professional learning, learn Linux This tool, coupled with their own language skills, so that can have a better development. In some large-scale internet companies, as an operations engineer, there may be limitations in future development, if we have our own development of some operations tools capabilities, we will be able to have a better value embodiment.
I'm going to learn a course called operating system this semester. The operating system is a very important thing, because each electronic device needs to have an operating system to operate properly. According to my understanding, the operating system is the management of computer systems of all hardware resources, in

Now we start with a summary of the three methods for Uc/os-ii to handle critical section code. The reason why I wrote so many big paragraphs before, mostly I don't understand why uc/os-ii in the implementation of the critical section of the problem is only to use the
