case. Linux has powerful networking capabilities and its TCP/IP code is the highest level. Linux provides full support for the current TCP/IP protocol, and includes support for the next generation Internet protocol IPv6. The Linux kernel also includes IP firewall code, IP anti-counterfeiting, IP service quality control, and many security features. These features are comparable to those of high-end routing devices provided by Cisco and other companies. These application cases prove that Linux is

fault), its usage bit is also set to 1. For the page replacement algorithm, the permutation algorithm is used for permutation of the candidate Page box collection (Current process: local scope; whole memory; global scope) is considered a circular buffer and has a pointer pin associated with it. When a page is replaced, the pointer pin is set to point to the next page box in the buffer. When a page needs to be replaced, the operating

answer message arrives and is passed to the customer. This technique, called at least semantics, guarantees that RPC executes at least once, but it is also possible to execute multiple times. ② A maximum of one semantics. Discard immediately and report the failure. It is the maximum semantics, ensuring that RPC executes at most once, but may not be executed. ③ does not make any warranties. When the server crashes, the customer does not get any help or assurance. RPC can not be executed or exe

The following seven parts describe what is the Android operating system? Through its open-source, demanding Activity, device debugging, application will never exit, developer collaboration, Java-success is also Xiao He, Intents (purpose, intention) these seven aspects are learned. The development of Android is indeed a thousand miles away, but many aspects are relatively immature to iPhone and Windows Mobil

Symbian is an operating system, and C + + is its native programming language. It provides software developers with the full functionality of the operating system. Of course, familiarity with C + + has a direct impact on the developers ' use of it, because development under Symbian OS will use the advanced features and

Mobile phone operating systems are generally only used on high-end smart phones. Currently, in the smartphone market, the Chinese market is still dominated by personal information-managed mobile phones. With more manufacturers joining the market, the overall market competition has begun to show a decentralized situation. From the perspective of market capacity, competition status and application status, the

concept of using a critical section to reflect mutex operations.3. Solutions for mutual exclusion-Disable Interrupt)In a single processor system, this is the simplest solution. That is, when a process enters the critical section, disable interruption and wait until it leaves the critical section before enabling. The premise that the CPU can switch the process is that the clock interruption or other interruptions can occur. This means that when a proc

. For an example of the above table, when the process pin is interrupted, Pou cannot access the shared variable count until the PIN process is finished before pout access, so the final result is correct.Third, summaryThe key to resolving the error between concurrent processes is to solve the shared variable access, and when multiple processes want to access shared variables, we must manage the rules of each process, otherwise the program will go wrong. With the PV operation, the related processe

If there is a small amount of IM base,develop their own agreements. These in the realization principle and the APNS/GCM have no essential difference, but have certain technical threshold. And most generally shouldTo use a push, the polling method is simply implemented. Of course there are a lot of third-party push platforms, such as the Aurora Push,Baidu's
