In statistical mechanics, a microstate is a specific configuration of a system that describes the precise positions and momenta of all the individual particles or components that make up the system. Each microstate has a certain probability of occurring during the course of the system's thermal fluctuations .
In physics, a microstate is defined as the arrangement of each molecule in the system at a single instant. A macrostate is defined by the macroscopic properties of the system, such as temperature, pressure, volume, etc. For each macrostate, there are many microstates which result in the same macrostate.

Microstate: the state of a system specified by describing the quantum state of each molecule in the system. For a classical particle – 6 parameters (x i, yi, zi, pxi, pyi, pzi), for a macro system – 6N parameters.

The collection of states of all the constituents is the microstate. To keep things clear, we refer to the macroscopic, thermodynamic state as the macrostate. The vast disparity between the number of possible macrostates versus microstates is at the heart of thermodynamic behavior!

A microstate is a specific arrangement of the constituent parts of a system that produces an externally observable macrostate. For example, consider a box containing two particles and only one quantized unit of energy (meaning it can't be divided up; it must go entirely to one of the two particles).
microstate is specified by a given spin configuration (σ1,σ2,...,σN). We notice im-mediately that the possible numbers of microstates are huge numbers when N is large. A Simple Example of microstates: Suppose we have a 6×6 checkerboard. Each square of the board represents a localised spin-1/2 particle with two possible spin
