The so-called generation of documents is to copy the relevant directory table of the file to the area specified in main memory, the establishment of a file control block, that is, the establishment of the user and the file connection.The so-called closed file is the user declared that the file is no longer in use, the system copies its contents of the file control block in main memory to a file directory entry on disk, and releases the file control block, thus cutting off the user's connection t

Interrupt:Interrupts caused by processor external events are called external interrupts, also known as interrupts. In x86, it is called an asynchronous interrupt, which is generated randomly with the CPU clock, and can occur in the execution of an instruction or after an instruction is executed. Includes I/O interrupts, external interrupts.Capture:Interrupts caused by internal processor events are called captures, which are referred to as anomalies in x86, also known as synchronous interrupts, i

Forced interruption:Such interruption events are not expected by the running program, but are caused by some kind of accident or external request signal.Voluntary interruption:A voluntary outage is an event that is expected by the running program, which is caused by a running program requesting an operating system service.Among the five major types of interrupts by function, input and output interrupts, external interrupts, machine failure interrupts, and procedural interrupts are forced interru

When I first approached, I thought the compiling principle would be very dull. But I'm browsing the information on the Internet. And let me have a new discovery, found that this course is really important. Baidu explains to us is that the compiling principle is a major professional course of computer science, which aims to introduce the general principle and basic method of compiling program construction. The content includes language and grammar, lexical analysis, parsing, grammar-guided transl

What is a construction method?The construction method is called when the new object is created. Each class has a constructor method, and if the programmer does not provide a constructor for the class, the Java compiler creates a default constructor for the class.What is a constructor method overload?Construction method overloading is similar to method overloading, where you can create multiple construction methods for a class, each of which must have

What does $ stand for in JavaScript?For example, I write a mouseover event: $(document).ready(function(){ $("p").mouseover(function(){ $("p").css("background-color","#333"); }); }); $ is just an ordinary character, because of the wide application of jquery, $ is used as the identifier of jquery. The rel= "stylesheet" attribute value is used to accommodate different browsers and add properties
