- 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

- What is a buffer overflow and how do I cause one?
In this context, a buffer is a portion of memory set aside for a particular purpose, and a buffer overflow is what happens when a write operation into the buffer keeps going past the end (writing into memory which has a different purpose)

- How do you implement a circular buffer in C? - Stack Overflow
Do you need a circular buffer or a queue? The required operations make it sound like queue I admit that with the requirement of a fixed size using a circular buffer make sense, but I'm not sure the question title reflects your actual question
- 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 )
- What is the Python buffer type for? - Stack Overflow
The buffer in this case is a sub-string, starting at position 6 with length 5, and it doesn't take extra storage space - it references a slice of the string This isn't very useful for short strings like this, but it can be necessary when using large amounts of data
