process as shown in the figure: If the cache implementation is not ideal, it will produce a high percentage of misses, because each cache misses will take additional time, resulting in system performance degradation. The term used to describe the relative accuracy of the cache is called the cache hit ratio, which is the result of the cache hit count divided by the total I/O requests. For open systems servers, such as UNIX, Win NT, and NetWare systems, the hit rate is usually no more than 50. I

Tags: input output file stream get custom fail--Standard code derivationThe C + + standard library encapsulates a buffer class streambuf for use by input and output stream objects. Each standard C + + output stream object contains a pointer to streambuf that the user can obtain by calling the Rdbuf () member function to directly access the underlying Streambuf object. Therefore, you can read and write data directly to the underlying

Java NIO BufferJava NiO buffers is used when interacting with NIO Channels. As you know, the data is read from channels to buffers, and written from buffers to channels.A buffer is essentially a block of memory to which you can write data, which you can then later read again. This memory block was wrapped in a NIO Buffer object, which provides a set of methods that makes it easier Memory block.Basic

This article mainly introduces the Buffer module in NodeJS, which is very detailed. For more information, see I. Opening Analysis The so-called Buffer refers to the "temporary storage zone", which is a memory block that temporarily stores input and output data. The JS language only has the String data type and does not have the binary data type. Therefore, NodeJS provides a global constructor

As we all know, buffer overflow is a common and extremely dangerous loophole, which exists widely in various operating systems and applications. The use of buffer overflow attacks can lead to the failure of programs, system restarts, and other consequences.More seriously, it can be used to execute non-authoritative instructions, and even gain system privileges to perform various illegal operations.Buffer ov

For the buffer zone, the most important operation is the read/write operation. The buffer provides two methods to read and write data in the buffer: Get, put, and array. The get and put methods can read and write data in three ways: read and write a single data in order, read and write a single data block at a specified position. In addition to the preceding meth

This blog is still based on Google's official document as the main line, the code example is completely taken from a demo project we are developing, through a period of previous attempts, the feeling that this combination of ways is more conducive to training and internal technical exchange. Or the words, there is no best, only the most suitable. I want to write a blog is also this reason, different technical topics may need to adopt a different style. Well, let's cut to the chase as soon as pos

What Are Protocol buffers? Protocol buffers are Google ' s language-neutral, platform-neutral, extensible mechanism for serializing structured C1>think XML, but smaller, faster, and simpler. Define how do you want your the data to being structured once, then you can use special generated source code to easily write a D read your structured data to and from a variety of data streams and using a variety of Languages–java, C + +, or Python.
