Node. js uses Buffer to encode and decode binary data. JavaScript is good at processing strings, but it is not very good at processing binary data because it was originally designed to process HTML documents. JavaScript has no byte type, no structured type (structured types), or even no byte array, only numbers and strings. (Original: JavaScript doesn't have a byte type-it just has numbers-or structured types, or http://skylitecellars.com/even byte ar

Buffer in Java NiO is used to interact with the NIO channel. As you know, the data is read from the channel into the buffer, written from the buffer to the channel. A buffer is essentially a piece of memory in which data can be written and then read from it. This memory is packaged into a NiO

As you know, there is a layer in PHP called the output buffer. This article is to explain what it really is? How does PHP internally implement it? And how do I use it in a PHP program? This layer is not complex, but it is often misunderstood, and many PHP developers do not have it in their hands. Today, let's get this together and figure it out. What we're going to talk about is based on PHP 5.4 (and above), and the OB layer in PHP has changed a lot

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

Buffer and CacheBuffer and Cache the definitionA buffer is something that have yet to being "written" to disk.A cache is something that have been "read" from the disk and stored for later use.CacheCache: Caching is a small but high-speed memory that sits between the CPU and the main memory.Because the CPU speed is much higher than the main memory, the CPU accesses the data directly from the memory to wait f

line buffering . In this case, the standard I/O library performs I/O operations when a newline character is encountered in the input and output. This allows us to output one character at a time, but only after a row has been written does the actual I/O operation. Row buffering is typically used when a stream involves a terminal. First example: (Hello World) Here, when we are not behind the Hello world, there is no Hello world in the results; And when we add to it, The result is this:

Company projects are often designed to serial communication, TCP communications, and most are real-time large data transmission, and then we all know that protocol communication must be related to, sealing, unpacking, sticky, check ... What ghost concept a lot of, say simple is to have an efficient reusable buffer.
