AS = Autonomous System (see Wikipedia). This is the corporation or entity to which an IP prefix (min /24) is registered, and which shows up in queries on sites like ipinfo.io.
BGP Path to Target IP prefix = ordered list of autonomous systems to reach target IP prefix
The point of BGP is to find the shortest AS path to an IP. Each AS has at least one router, and each router has at least one other AS peer. A router will forward the packet as far as it can given the peers it knows, until the AS list is length 0, at which point the controlling AS routes traffic to its destination.
