What is a flush?

Answer 1

It is a construct to minimize traffic between layers.
So uday kiran told you that not every key is directly sent to program but first gathered and transported on demand.
That idea is used in different contexts.

Especially in graphics programmming not each change is sent to front end. That would lead to very high traffic between backend and front end.
All changes go to front end on flush.

Also in real life:
If u buy on Amazon u dont directly buy each single item but put it into a basket.
Only if you click buy, you buy all your basket.
That buy click is similiar to flush.

Answer 4

I wish to add that flushing a keyboard buffer, a data stream, or an interprocess communication pipe means to empty the queue without processing any pending data.

An example would be the "Press any key to continue" prompt. Before showing the prompt, the program should flush any keypresses held in the keyboard buffer. Otherwise, the next key waiting in the queue will close the prompt immediately.

Answer 8

A buffer flush is the transfer of computer data from a temporary storage area to the computer's permanent memory. For instance if we make any changes in a file, the changes we see on one computer screen are stored temporarily in a buffer.
