It is a thermodynamic property and is a measure of disorderliness or randomness of a system, i.e, greater the disorder in a system, higher is the entropy of that system.

Entropy is a state function. It does not depend on path. $$\Delta S = {S_2} - {S_1} = \frac{{q(reversible)}}{T}$$
$q=$ amount of heat (At temperature T) absorbed by the system in a reversible way.
