(N/A) Accuracy refers to how close a measured value is to the true or actual value of the physical quantity.
Precision refers to the resolution or the limit to which a physical quantity is measured,determined by the least count of the measuring instrument.
Example: Consider a digital clock showing the time as $10:11:12 \text{ AM}$. The least count of this clock is $1 \text{ s}$,so it has higher precision. (Measurements taken with an instrument having a smaller least count are more precise.)
Now,consider an analog clock without a second hand showing the time as $10:13 \text{ AM}$. The least count of this clock is $1 \text{ min}$,so it has lower precision. However,if this analog clock is perfectly synchronized with the standard time,it may be more accurate than the digital clock if the digital clock is running slightly fast or slow.

Precise measurements of physical quantities are a need of science. For example,to ascertain the speed of an aircraft,one must have an accurate method to find its positions at closely separated instants of time. This was the actual motivation behind the discovery of radar in World War $II$. Think of different examples in modern science where precise measurements of length,time,mass,etc.,are needed. Also,wherever you can,give a quantitative idea of the precision needed.
