- Cache 和 Buffer 都是缓存，主要区别是什么？ - 知乎
Buffer的核心作用是用来缓冲，字面意思缓慢冲击。 比如你每秒要写100次硬盘，对系统冲击很大，浪费了大量时间忙着写处理，用个buffer缓冲区暂存起来，变成每秒要写10次硬盘，对系统冲击极大程度缓解了，因为写入效率变高了。
- terminology - What does it mean by buffer? - Stack Overflow
Here, the buffer array is used to store the data read by read (2) until it's written; then the buffer is re-used There are more complicated buffer schemes used, for example a circular buffer, where some finite number of buffers are used, one after the next; once the buffers are all full, the index "wraps around" so that the first one is re-used

- How to determine the size of an allocated C buffer? [duplicate]
Since buffer is a pointer (not an array), the sizeof operator returns the size of a pointer, not the size of the buffer it points to There is no standard way to determine this size, so you have to do the bookkeeping yourself (i e remember how much you allocated )
- ORA-06502: PL SQL: numeric or value error: character string buffer too . . .
PL SQL: numeric or value error: character string buffer too small is due to the fact that you declare a string to be of a fixed length (say 20), and at some point in your code you assign it a value whose length exceeds what you declared
- Uncaught ReferenceError: Buffer is not defined - Stack Overflow
It turns out that there is third-party plugin that provides all node js polyfills (not just Buffer) out of the box: node-polyfill-webpack-plugin It brings all polyfills as its own dependancies, so you should use excludeAliases config property to define what polyfills you do not want to be included
