What side of the brain are childhood memories stored?

This is a debatable question. However, memories are stored throughout the entire brain by neurons. However, the area memories are stored in, is the hippocampus. Hence, both sides of the brain are responsible for storing childhood memories. (Long-term memory).

Ican only answer your first question, a machine is like a human body because it's a little similar. they both almost work like the same.
