path vector and distacne vector

path vector routing protocol --> it consider the AS(autonomous system) as hop and there is only BGP routing protocol that is path vector routing protocol .
for distance vector routing protocol --> it considers the router as hop , for example :RIP routing protocol

Distance-vector：for exmple, rip, when it exceed 16, the route will be invalid.
Path vector: for exmple.BGP

@Amr_Fayrouz_Elattar hello sir, the path vector maintains the path information that gets updated dynamically, unlike distance vector routing, every entry in the routing table contains the destination network, the next router and the path to reach the destination, while the distance vector determines the best route based on distance, which means that distance vector doesn't learn the whole topology, it selects the path with the minimum hops.
