two stroke enginge: they are called so because they complete the thermodynamic cycle in two strokes; up and down.they do not have any valves to open up the ports. fuel efficiency is very low, wastage of fuel is inevitable, scavenging can prevent only very little fuel loss.flywheel needed can be smaller in comparison to the four stroke engine.here there is an extra port called the transverse port. they are mostly used in low power applications.
four stroke engine :
they are so called because they complete the thermodynamic cycle in four strokes;two ups and two downs. they have valves to open the port at the appropriate time. fuel efficiency is good as there is no wastage of fuel here. huge flywheel needed especially in 'single cylinder' four stroke engines as a single power stroke has to supply power for two ups and one downs of the piston stroke. they are mostly used in high power applications.
Internal engine has its energy ignited in the cylinder. like 99.9% of engines today An external combustion example is a steam engine where the heating prosses is done in an boiler out side the engine.

If I had two cars and they both had engines, I would look at the two engines (part) and compare them to one another - which is a better engine? Then maybe I would do that with the two steering wheels, seat liners, transmissions etc. This would be a part to part comparison. If I had two cars and I compared them to one another OVERALL by looking at general functioning or general consumer's guidelines of each one, this would be a specific comparison or a comparison.
