Question

Which buffer will lose data when it is full?

(a) linear buffer

(b) circular buffer

(c) directional buffer

(d) double buffer

I had been asked this question during an interview.

This intriguing question originated from Types of Buffers in division Buffering and other Data Structures of Embedded Systems

Answer 1

Right choice is (a) linear buffer

For explanation: The linear buffer has a single piece of contiguous memory which is controlled by the pointers whose address increments linearly and it will lose data when it is full and fail to provide data when it is empty.
