Answer:
Lowest Level; Machine Language.
Explanation:
The lowest level of a computer is machine language, which are strings of 0's and 1's in bits, and it's possible to perform tasks at this level. It's however difficult to do and humans created <em>Assembly</em>; a type of low level programming language to be readable, and converts to machine language so that we don't have to work in binary.
Depends really. Have you got prior coding experience? The semantics of certain languages are much easier to pick up if you've had prior experience, but it might seem impossible to someone who has minimal experience.
Assuming that you're no older than 15 or 16, I'm going to suggest Python. It's a simple, high-level language that's easier to understand than most languages. If you think you've got enough experience to quickly understand and pick up things, then I'd probably say R is a good language to start with. It's very well-suited for AI and tends to be a favourite for AI researchers.
