Type-ahead
<operating system> The facility where the user can type more characters before the system has fully responded to those already typed.
Type-ahead is common on most current systems. It allows the user to type without worrying that the computer may miss input because it is temporarily busy, e.g. reformating a page, checking spelling, or simply suffering from network latency.
There is usually some limit to the amount of input the system can buffer, beyond which it _will_ lose input.
