buffer flush

A buffer flush is the transfer of computer data from a temporary storage area to the computer's permanent memory. Here's one example of a buffer flush: When you make changes in a Word document, the changes you see on your computer screen are stored temporarily in a buffer. When you save your work, the changes that you've made to your document since the last time you saved it are flushed from the buffer to permanent storage on the hard disk.
