1.	Which of the following is similar to the high and low water marks at the coast?(a) minimum and maximum water level(b) low and high water mark(c) small and big water mark(d) medium and high water markThis question was posed to me in a national level competition.This interesting question is from Types of Buffers topic in chapter Buffering and other Data Structures of Embedded Systems
Answer» Right answer is (b) low and high water mark To ELABORATE: There are some errors in the linear buffering which includes the loss of data especially in the regular sampling. This can be avoided by the pointers that are checked against certain values and the result is used to fetch more data. These points are KNOWN as the low water mark and the high water mark. It is NAMED so because it is similar to the high and low water marks SEEN at the coast which INDICATES the maximum and minimum levels that the tidal water will fall and rise.
