speed than the single-server mode speed can be faster.E) low cost: different from the HTTP mode, the server does not necessarily put a high-quality computer room, can only a small number of room. Many servers can be used in the United States low-cost servers, 1G bandwidth one months on more than 1000 yuan, this price seconds to kill a lot of domestic computer room. Before 2008, I also saw someone renting some houses and putting on some ordinary computers to do peer-to speed. Especially looking

makes the design of Web page more complicated. Relative to the Table layout (table) in the HTML4.0, css+div although not high, but at least more complex than the table positioning, even for the site design experts are also prone to problems, not to mention beginners, which has affected the application of the XHTML website design language to a certain extent.2, the CSS file exception will affect the normal browsing of the entire site. CSS Web site design elements are usually placed in one or sev

that proves to be an application problem is not the thread's disadvantage.The advantages of line threads for processes:1. Low Overhead2. Sharing of resources is good.Line threads disadvantages for the process:1, shared resources need to spend a certain amount of lock resources, synchronization is relatively complex.2. A thread crash can cause the entire process to crash, which of course is problematic for its own application==========================

A comparison between sequential storage structure and chain-type storage structure Advantages and disadvantages in order to store, adjacent data elements are also adjacent to the storage address (logical and physical unity); The address of the available storage units in memory must be contiguous. Advantages: Large storage density (=1), high storage space utilization. Disadvantage: inconvenient when inserting or deleting elements. When chained storag

Now the trend is multi-language blending programming, so this article is for mixed programming. 1,c++ Advantages: 1.1, performance advantages. 1.2, evolutionary (reusable), evolving the team's convenient class library. 2,c++ a small advantage or suspected advantage: 2.1, "Snake Balm". In the era of mixed programming, the value of "Snake Balm" is small. 3,c++ Fundamental disadvantages: Difficult to learn. Novice by the pointer to die, in hand (about

Singleton mode: A singleton pattern means that there is only one instance. The singleton pattern ensures that a class has only one instance, and instantiates it and supplies the instance to the entire system. This class is called a single instance class. The single case model has three kinds: the lazy type single case, the A Hungry man type single case, the registration type single case. 1. The lazy type single case Advantage: The first call is initialized to avoid a waste of memory. Disadvan

The usage and advantages and disadvantages of anonymous function in JS Anonymous functions are effective in ensuring that JavaScript is written on the page without causing global variables to be contaminated.This is very effective and graceful when adding JavaScript to a page that is not very familiar. One, what is the anonymous function. There are generally three ways to define a function in javascript: Functions keyword (function) statement:functi

action is taken on the values in a and b memory, which means that you are working on another two separate memory spaces that are not associated with a and b, so naturally you cannot swap the values of A and B. So why is the first method possible? Since the F () function is invoked at this time, the incoming formal parameter is a and b, so that is to say x=a,y=b, then obviously *x and a are a concept, and the operation *x and *y are actually the * (a) and * ( b), so when swapping *x and *y, the

The advantages offered by Oracle Resilient Cloud and data warehousing are obvious, first of all, that a single vendor provides all the underlying components: Oracle's one-stop approach helps simplify licensing, support, upgrades, and consolidation, all handled by a single vendor. This may help to prevent the frequent prevarication between vendors on technical issues. It is easier to configure, upgrade, and consolidate with a single vendor, simplifying the contact and validation paths of these is

DatabaseType Characteristics Advantages Disadvantages relational databaseSQLite, Oracle, MySQL 1, relational database, refers to the use of a relational model to organizeDatabase of data;2, the most characteristic of relational database is the consistency of affairs;3, in simple terms, the relational model refers to the two-dimensional table model,A relational database is a data organization composed of two dimensional tabl

C/s also known as client/server or client/server mode. Servers typically use High-performance PCs, workstations, or minicomputer, and use large database systems, such as Oracle, Sybase, Informix, or SQL Server. Clients need to install dedicated client software. b/S is the abbreviation for Brower/server, as long as the client installs a browser (Browser), such as Netscape Navigator or Internet Explorer, the server installs Oracle, Sybase, Informix, or Databases such as SQL Server. The browser i

The pointer is the C language only so successful one of the important reasons, of course, anything, is often a two-sided, essentially one, looks is both sides, the key is to ingenious, not more than the distinction between advantages, disadvantages. C language is mainly for the hardware and system of the underlying programming, in the hardware and system-level programming, the flexibility of the data requirements, in other words, the meaning of the d

Advantages and disadvantages of indexing Why do you want to create an index? This is because creating an index can greatly improve the performance of the system. First, you can guarantee the uniqueness of each row of data in a database table by creating a unique index. Second, you can greatly speed up the retrieval of data, which is the main reason to create indexes. Third, you can speed up the connection between tables and tables, especially in term

A Disadvantages: 1. Portability is the biggest drawback of stored procedures and triggers. 2, occupy the server side too many resources, to the server caused a lot of pressure 3, can not do DDL. 4, the trigger scheduling error is difficult, and the data is easily inconsistent, late maintenance inconvenient. Advantages: 1, precompiled, has been optimized, high efficiency. Avoids the inefficiency of SQL statements being transmitted over the network a

1. Distinction between Ngui and Ugui 1) Ugui Canvas has world coordinates and screen coordinates 2) Ugui image can be used material 3) Ugui through mask to cut, and Ngui through the panel clip 4 Ngui rendering sequence is through the depth of the widget, and Ugui render order according to the hierarchy order, the more below rendering at the top level. 5) Ugui do not need to bind Colliders,ui can automatically intercept events 6 Ugui Anchor is relative to the parent object, does not provide advan
