application implements the operation of the computer by calling it. And most of the WIN32 subsystem APIs are implemented through NATIVEAPI. the settings for NATIVEAPI are based on version compatibility considerations. It enters into kernel mode by means of software interrupts. Here are a few important concepts:Virtual Memory Management: The concept of virtual memory is introduced into Windows, and then the physical memory and virtual memory are associated with some kind of mapping. Each process

execution path; the so-called execution path refers to the directory list where the operating system searches for a local executable file.The same level directory in Jdk\bin contains the Src.zip file, which is the source code for all public classesGet more source code (compilers, virtual machines, local methods, and private helper classes, etc.) with access to: Oracle.net.Here is the anatomy of the JDK section:The difference between the JDK and the JRE can be seen clearly:There are three types

done in the instrument device, with a band-pass filter to set the center frequency of 21.4MHz, filtering out other signals, extracting 21.4MHz if signal. The signal that is output through the IF filter is the signal that we want to detect.There are several factors in the operation of the filter: the center frequency is 21.4MHz, fixed, and its 30dB bandwidth can be changed. For example, for broadcast signal, its bandwidth is generally dozens of khz, if the signal bandwidth is 25kHz, if the bandw

in the test for about two months, has been purely manual testing, manual Writing use cases, manual testing, daily repetitive do some work, feel very boring, and super insecure, their alternative is too strong, any person can do my present work. In order to become more valuable, so determined to start learning automated testing. At present, mainly to see some online public class video, I feel that Wu old public lessons do quite good, you can learn, because PPT does not share, so will be the video
