A buffer in a computer is place where information is stored whilst being moved from one electronic device, to another. Or from on process to another. A buffer can only really get too 'full' if the information coming from one place overwrites the contents of the buffer, before the destination device or process reads it. That would occur if either device were to stop responding.

In a computer program a buffer over flow can occur when the memory in a position near the buffer get's too full and information get's written to the buffer by mistake, this is known a Buffer Overflow the source of many software crashes and security vulnerabilities.
