, but its redundancy is 0, when the hard disk damage, The data is also damaged. In the production environment of the server, the most used is RAID5 or RAID6, which provides read and write performance, but also provides redundancy. RAID1 are often used in situations where the accuracy of the data is required and strictly.Let's summarize the pros and cons of each of these 4 commonly used RAID levels: RAID level Speed Redundancy of Disk Utilization RAID

The so-called custom-made delete is to provide the target template with a free choice of the destructor interface, the advantage is that the smart pointer template can no longer only manage memory separately, we can also use it to manage the file pointers and other things. There are two ways to implement it, here we take the share pointer for example.1. Pass the template parameter of a class and give the vacancy a value, the template sets the class as a member variable, which is instantiated by

Sessionid=request.getrequestedsessionid ();When a client sends a request, the server automatically checks to see if the client has cookies enabled based on the information submitted to the client browser and, if enabled, no longer URL rewriting. If not, continue with URL rewriting.URL rewriting can be done through the Encodeurl (String url) method of the Response object.public string encodeurl (string url);Encodes the URL that contains the SessionID. If the encoding is not required, the URL is

In general, it is relatively simple to horizontally center a fixed-width block element, and we only need to set the width of the block element and set margin:0 Auto. However, for block elements that cannot be set to a fixed width, this trick does not work.Let me introduce the three commonly used methods to set the horizontal center of an indefinite wide block element.First: horizontal centering with float+relativeCSS code:.
