So, here's a summary of the two data types of the master key for a comparison.Advantages of using the INT key:1, need very small data storage space, only need 4 byte.2, insert and UPDATE operations use INT for better performance than GUIDs, so using int will improve the performance of your application.3, index and join operations, INT is the best per

The full duplex of a switch means that the switch can receive data while sending data. It cannot directly connect the input/output ports with different rates and is prone to packet loss, in particular, it supports switching between ports at different speeds to ensure collaboration between high-speed ports and low-speed ports. With the gradual development of network applications, telecom-grade switches, especially layer-3 switches, have become the focus of competition in today's market. However,

(1) circuit switching: Before communication, a physical channel exclusive to both parties must be established between the two parties (composed of the switching devices and links of both parties ), therefore, it has the following advantages and disadvantages. Advantages: ① Because the communication line is dedicated to users of both parties, the data transmission latency is very small. ② Once a physical path is established between the communication pa

Original article translated from: Simplified. If the database can run continuously, of course, it is best. However, this is often costly. Sometimes it is even more advantageous than what it gets. In the sqlserver2008 database, there are many high availability solutions. For example, you can use failover clusters, database images, log transmission, replication, and other means to improve the high availability of the database. Because there are many solutions, the database administrator has to m

I. Ordinary table (Heap table): For most design scenarios, there are advantages and disadvantages. Advantages:1. Simple and convenient grammar2. Suitable for most scenes Disadvantages:1. Update log cost is large2.Delete Unable to free space (HWM high Water mark does not fall)3. Table record too large retrieval too slow4. Index back to table read overhead very much5. Even if the orderly insertion, it is di

"Abstract" Linux User Configuration device-driven development: Not all device drivers are written in the kernel, and in some cases, writing drivers in user space can better address the problems encountered. This paper analyzes the advantages and disadvantages of user-driven drivers.1. Advantages of User space driver1, can be linked with the entire C library.2, in the drive can use floating point number, in some special hardware, may need to use floati

Some CPUs are already integrated graphics in the inside, before buying can understand the integration of the graphics card in the inside, according to their own needs to buy. Below I tell you a simple introduction of the advantages and disadvantages of integrated graphics. Method/Step 1, here first to say that the 1th, some motherboards are not supported to install independent graphics, which are relatively early motherboards, or a very

The advantages of Ajax The advantages that Ajax brings to us are basically deeply appreciated, and here I just briefly say a few things: 1, the biggest point is the page does not refresh, in the page with the server communication, to the user experience is very good. 2, the use of asynchronous way to communicate with the server, do not need to interrupt the user's operation, with more rapid response capabilities. 3, can put some of the previous server burden to the client, the use of idle cl

U disk partition format is good or bad, directly affect the file transfer performance, speed and so on. So everyone in the U disk partition, you should carefully choose what type of u disk format. But we do not know which kind of U-disk format is good, which is bad, below we will focus on the 4 most common U disk format: FAT16, FAT32, NTFS, exFAT, and the 4 kinds of U disk format, each of the advantages and disadvantages are different. FAT16 format:

better than an array:1. Insert and delete operations. If an element is inserted in the middle of an array, the memory address of all the elements behind the element will be moved backwards. The same is true of the deletion. Only when the last element of the data is inserted and deleted. . The list only needs to change the node information within the node that is necessary to change it. You do not need to change the memory address of the node.2. Memory address utilization. No matter how much spa

Thread synchronization: Multiple threads accessing the same resource at the same time, waiting for resource access to end, wasting time, inefficientThread Async: Access other resources while idle waiting while accessing resources, implement multithreading mechanismAsynchronous processing is, you ask me questions now, I can not answer you, wait for me to take the time to deal with your problem. Synchronization is not the reverse, the synchronization information is processed immediately-until the

performance requirements are high, programmers may be required to replace them with other similar algorithms to ensure performance is preferred, but in some cases, replacing recursion with other algorithms may not necessarily improve the performance of the algorithm, but recursion is the best algorithm (which generally refers to fewer recursive hierarchies).In short, the use of recursion has its advantages, there are disadvantages, whether the progra

described by the assembly, you can get the details of the attribute at run time, or as an indirect way of instantiating a class or invoking a method, if the class name on the method is specified as a string (the class name is a parameter), you may choose to instantiate the method so that it is called at run time. Instead of being called at compile time.64bit support, generics and iterators, anonymous methods, partial classes, nullable types.Third, disadvant
