me through callback.The blocking mechanism is: when you wait for a response, you will suspend yourself until you get the result of this book.The non-blocking mechanism is: no matter whether the boss tells you, you play first, but check whether the boss has answered you later.Ii. Bio (Block Io blocking Io): the server will open a dedicated thread for each client link, that is, the relationship between 1vs1. The number of threads that a server can start is fixed, if a bunch of requests come in, t

channel. The channel differs from the flow where the channel is bidirectional and can be used for read, write, and simultaneous reading and writing operations.The channels of the underlying operating system are generally full-duplex, so full-duplex channel streams can better map the underlying operating system's APIs.There are two major types of channel:1.SelectableChannel: User network read/write2.FileChannel: For file operationThe Serversocketchannel and Socketchannel that follow the code are

The event separator waits for the completion of the Read event (compared with the reactor); When the event separator silently waiting for the completion of things to come, while the operating system has started to work, it read data from the target, put into the buffer provided by the user, and finally notify the incident separator, this thing I finished; event handler prior to notification by ev

Java Network IO Programming, from traditional bio (synchronous blocking) to NiO (synchronous non-blocking) to AIO (asynchronous non-blocking). Scenario: The client wants to send a request to the server, the server will set up a thread response for each client, the problem is, if the client has a delay and other exceptions, more network anomalies, so that the server for its established thread, has been in the waiting state, This thread takes a long ti

For SynchronizationI/O,WhenI/OOperation execution,The application must wait,Till nowI/OExecuted.Opposite,AsynchronousI/OOperation running in the background, I/OOperations and applications can run simultaneously,Improved system performance.Use asynchronousI/OWill improveI/OTraffic,If the application is operating on a bare Device,This advantage is more obvious. Therefore, similar to databases,Applications such as file servers often use AsynchronousI/O,Make multipleI/OOperation execution at the sam

You can change the AIO parameters for your system withChdevCommand onAio0Pseudo-device, or by runningSmitty AIOOn AIX 5.3 systems-You can even use the poorly encrypted entedAiooCommand. An important thing to remember though-is that you can set the values online, with no interruption of service-But-They will not take affect until the next time the kernel is booted. Some additional documentation is available at the locations below: Ht

That is, others may have to wait, but not at the scene, but go home and so on, you can do other things, water is full, the water union to inform them.This is actually very close to the current social division of labor refinement of the reality, but also the use of existing resources to achieve the concurrency effect of a very economic means, rather than to a parallel processing, although that is the simplest, but also the

HT to access it. If the user is not on this list, the user is denied. This is another form of access control. The users ' permissions and rights is based on their identity, clearance, and/or group membership. Access controls give organizations the ability to control, restrict, monitor, and protect resource availability, integrity , and confidentiality.Access control is a broad concept that includes several mechanisms for application in computer systems, networks, and information. Access control
