Five I/O models under Linux1) Blocking I/O (blocking I/O)2) non-blocking I/O (nonblocking I/O)3) I/O multiplexing (SELECT and poll) (I/O multiplexing)4) Signal-driven I/O (signal driven I/O (SIGIO))5) asynchronous I/O (asynchronous I/O (the POSIX aio_functions))The first four types are synchronous, and only the last is asynchronous IO.blocking I/O Model:Summary: The process will block until the data copy is completeThe application c

, the function has a result notify me (callback notification)3. Blocking is called me (function), I (function) did not receive the data or did not get the results, I will not return.4. Non-blocking, just call me (function), I (function) immediately return, via select Notify callerThe difference between synchronous IO and asynchronous IO is that the process is blocked when the data is copiedThe difference between blocking IO and non-blocking IO is that the application's call returns immediatelyIn

don't care if the boss tells you that you're going to play on your own, and of course you have to check in a few minutes occasionally to see if the boss has returned the results. Here the blocking is independent of the non-blocking and whether synchronous asynchronous. It has nothing to do with how the boss responds to your results. The main difference between synchronous and asynchronous is that it will not cause the request process (or thread) to block . Synchronization causes the re

to return directly or wait for the ready; While synchronous and asynchronous refers to the mechanism of accessing data, synchronization generally refers to the active request and wait for the completion of the I/O operation, when the data is ready to read and write must block (difference between ready and read and write two stages, synchronous read and write must block), asynchronous refers to the active request data can continue processing other tasks, and then wait for I/ Notification that th

the custom lighting model in Surface shaderWhen you're writing surface Shaders, you're describing the properties of a surface (reflection color, normals ...). ), and the interaction of light is calculated by a light model. The built-in lighting models have Lambert (diffuse illumination) and blinnphong (specular illumination).Sometimes, you might want to use a custom lighting model, which is possible in surface shader. The illumination model is actuall

At present, the most important thing in the object-oriented thinking is "abstraction", and the most important thing in the software design goal is "to respond to changes in demand (increase or change)".Think about it, whether it is "layered" thinking, or "design pattern" thinking, or "generic" ideas, etc., it should be said that the ultimate goal is to "respond to changes in demand", and are filled with "abstraction."Stratification is to make "big change small, easy to change", and for different

In fact, the design of concurrent network programs in Linux, has always been a lack of methods, such as the typical Apache model (Process per Connection, refe

Most Silverlight-based applications are written in managed code and take full advantage of the Silverlight application model. However, you can choose to use a simplified programming model. Silverlight provides the following two distinct models for application development: Silverlight's managed API, which uses code that runs on the common language runtime (CLR) of Silverlight. You can use the managed APIs for compiled languages such as Visual Basic a

Brief introduction In part 1th of this series, you will create an application that combines the advantages of the canvas API and the HTML/CSS two models. The canvas API is an ideal choice for WEB applications that require high-performance, low load graphics. However, it is short-sighted to overlook the advantages of the traditional HTML/CSS model by simply designing the entire application around canvas. Rather than taking it for granted, learn some f

server| Backup | recovery | data | database There are countless ways to back up a database in SQL Server 2000. No matter how big your database is or how frequently you change it, you have a backup strategy that meets your needs. Let's look at a few basic backup strategies that work in different environments. This article assumes that you have permission to back up the database. In other words, you are either a system administrator, or a db_owner or a backupadministrator. Also, we assume that you

Reference: http://blog.csdn.net/u013341524/article/details/19557597 The type of database is divided according to the data model, and any DBMS is designed according to the data model, which means that the database must be organized into a data model conforming to the DBMS. At present, the data models used in the database system are: Hierarchical model, network model and relational model. The fundamental differenc

1 Questions model selection Problem: There are several models to choose from for a learning problem. For example, to fit the sample points of a group, you can use linear regression or polynomial regression. So what is the best model to use (to be able to achieve a balance between deviations and variances). There is also a class of parameter selection problems : If we want to use a regression model with weights, then how to choose the parameters in th
