ideal machine is originally an hypothetical mechanical system in which energy and power are not lost or dissipated through friction, deformation...... the output energy is equal to the input energy. Therefore, mathematically we can express it as input=output
difference:-
1 the efficiency of ideal machine should be 100% but the efficiency of a practical machine is always less than 100% because of the second law of thermodynamics
2 Ideal machines are said to have parts which are weightless and frictionless but practical machines have parts which have weights and friction

Answer:
Ideal machines are said to have parts which are weightless , frictionless and strings if any are inextensible. Practical machines have parts which have weights, friction and it causes some loss of work done. So these are the differences between Ideal Machine and Practical Machines.
