Definition from
WTCS.ORG:
A temporary storage place for data, designed to compensate for a difference In transmission speeds or to hold data when there is a difference in timing of events. It can be a software program, a storage facility or a hardware device, ensuring the data always has somewhere to go, even if it has to be held up for while in the buffer until it can be transmitted to the destination.
Example sentences:
Circular Buffers are use for data transfer between two processes. The Producer process places items into the Circular Buffer and the Consumer process removes them. The variable capacity of the Circular Buffer accommodates timing differences between the Producer and Consumer processes. (NET Code)
The buffer editor is one of the most unique and powerful features of the EPROM+ system. Allowing full access to the system's buffer, the editor provides you with a full screen display of the contents in both hex and ASCII formats. (arlabs.com)
It is generally accepted that On-Line Transaction Processing (OLTP) systems benefit from large database memory buffers. (Portal)

缓冲区，一个用于存储速度不同步的设备或优先级不同的设备之间传输数据的区域。通过缓冲区，可以使进程之间的相互等待变少，从而使从速度慢的设备读入数据时，速度快的设备的操作进程不发生间断。
Example sentences:
在刻录过程中出现“Buffer Under Run”(缓冲区数据不足)的错误，无法完成刻录，造成盘片报废 (QQread)
cache 和 buffer的区别： Cache：高速缓存，是位于CPU与主内存间的一种容量较小但速度很高的存储器。由于CPU的速度远高于主内存，CPU直接从内存中存取数据要等待一定时间周期， Cache中保存着CPU刚用过或循环使用的一部分数据，当CPU再次使用该部分数据时可从Cache中直接调用,这样就减少了CPU的等待时间,提高了系统的效率。Cache又分为一级Cache(L1 Cache)和二级Cache(L2 Cache)，L1 Cache集成在CPU内部，L2 Cache早期一般是焊在主板上,现在也都集成在CPU内部，常见的容量有256KB或512KB L2 Cache。 Buffer：缓冲区，一个用于存储速度不同步的设备或优先级不同的设备之间传输数据的区域。通过缓冲区，可以使进程之间的相互等待变少，从而使从速度慢的设备读入数据时，速度快的设备的操作进程不发生间断。 (DDVIP)
