本文探讨了计算机科学中两种重要的缓冲区错误：缓冲区下溢与缓冲区溢出。缓冲区下溢发生在数据读取速度超过填充速度时，而缓冲区溢出则是因为写入的数据超出了缓冲区的边界。这两种错误都可能导致程序运行不稳定或安全漏洞。

Underrun(underflow)ide

In computing, buffer underrun or buffer underflow is a state occurring when a buffer used to communicate between two devices or processes is fed with data at a lower speed than the data is being read from it. This requires the program or device reading from the buffer to pause its processing while the buffer refills. This can cause undesired and sometimes serious side effects, since the data being buffered is generally not suited to stop-start access of this kind.ui

Overrun(overflow)this

A buffer overflow occurs when data written to a buffer, due to insufficient bounds checking, corrupts data values in memory addresses adjacent to the allocated buffer.c
