Both bacon and sausage come from the same animal which is a pig.
So bacon and sausage are essentially the same meats but bacon and ham are different in the fat content and calories.
Sausage tends to have more calories and more fat content than bacon does so when it comes to the healthier meat from a pig it would be better to eat a few slices of bacon over a few links of sausage.
Still eating too much bacon could be unhealthy as well because of all the bacon grease.
But both sausage and bacon is healthy in moderation.
Pork would be better as it's less greasy than sausage or bacon although pork is also pig meat.
The difference between pork, ham and bacon is that the ham is usually cut from the hind leg of a pig or from other parts of the carcass.

The difference between pork, ham and bacon is not all that much as it's all the same meat cut from the same animal which is a pig.
Ham and bacon are pork but it's just cut from different parts of the animal which gives it a different flavor.
