Question

In which case, the buffer is used by two software task?

(a) single buffer

(b) linear buffer

(c) double buffer

(d) directional buffer

I have been asked this question in class test.

Enquiry is from Types of Buffers in section Buffering and other Data Structures of Embedded Systems

Answer 1

Right option is (a) single buffer

To elaborate: In the single buffer, the buffer is used by two software tasks to insert or extract information. The problem with this buffer is that the water level is above or below, and the free space that is used to fill the buffer does not lie in the correct location.
