system's interprocess communication mechanism reveals their similarity: the Synchronized method or block provides functionality similar to the operating system primitives, and their execution is not interfered by the multithreading mechanism, which is equivalent to block and wake up Primitives (this pair of methods are declared as synchronized). Their combination allows us to implement an array of sophisticated inter-process communication algorithms (such as semaphore algorithms) on the operati

until the process has unblocked the signal and executes the recursive action.DrawingWhen a signal is sent to a process, the Process control block PCB controls the direction of the signal, the pending set (readable only, not writable), the blocking set (readable writable) are 64 digits, because there are 64 signals, each bit corresponds to a signal, a signal to pass through these two sets to arriveThe initial state of the pending set is all 0, the sig

currently running thread can invoke the join () method of another thread, and the currently running thread will go to the blocking state until another thread finishes running before it goes to the ready state for a chance to resume running.Through one of several ways, a thread can be from a blocked state to a running state.1. The thread is put to sleep, and the specified number of milliseconds has elapsed.2. The thread is waiting for the I/O operation to complete and the operation has completed

characteristics of the wait () and notify () methods determine that they are often used with synchronized methods or blocks.A comparison between them and the operating system's interprocess communication mechanism reveals their similarity: the Synchronized method or block provides functionality similar to the operating system primitives, and their execution is not interfered by the multithreading mechanism, which is equivalent to block and wake up Primitives (this pair of methods are declared a

causes the unblocked thread to be randomly selected from the thread that was blocked by calling the wait () method of the object, and we cannot predict which thread will be selected, so be careful when programming and avoid problems with this uncertainty. (2) In addition to notify (), there is also a method Notifyall () can also play a similar role, the only difference is that the call to the Notifyall () method will be called by the Wait () method

Today, when you open a page in the browser, suddenly eject the "Network Connection Error" dialog box, display "Network connection error (error code 118), please use 360 Network emergency box to check the Internet", but with the first aid box checked the network, or can not be resolved, shuxin still can not solve, The repeated tests finally solved the problem.

First: Check the physical connection is unblocked. Configure the IP address on the network adapter connected to the client and the server to ensure that the IP address gigabitethernet1/0/0 the server-side interface is on the same network segment. Ping gigabitethernet1/0/0 interface from the client IP address, if you can ping, then the connection is unblocked, then the physical line failure can be excluded

In this regard, we may wish to open the local workstation's IE browser window, and in the window address bar to enter the wireless router's background management address, click the ENTER key to open its background login interface, and then correctly enter the administrator account and password, access to the wireless router background management in

of the synchronization feature class EventWaitHandle (subclass AutoResetEvent, ManualResetEvent), Semaphore and mutexes inherit from WaitHandle, so the underlying principle is consistent, maintaining a system kernel handle. But we still need to simply distinguish between the three types of classes. The EventWaitHandle maintains a Boolean type object (called a "block State") produced by the kernel, and if its value is false, the thread waiting on it is blocked. You can call the type's set met
