OSPF is a link-state routing protocol.
OSPF is a classless link-state routing protocol. RIP version 1 and IGRP are both classful distance vector routing protocols, EIGRP is a hybrid protocol that supports classless addressing.
There are actually two OSPF and IS-IS
In a distance vector routing protocol, such as RIP or EIGRP, each router sends its routing table to neighboring routers. The routers don't know the topology, i.e., how other routers are interconnected. In a link state routing protocol, such as OSPF or IS-IS, routers first exchange information about connections within the network (or an area of the network), and build a topology table. Then each router uses Dijkstra's algorithm to calculate the best route to each destination.
OSPF stands for open shortest path first. OSPF is an exterior routing protocol. OSPF uses Path vector routing algorithm.
OSPF is short form of open shortest path first. OSPF is based on linked state routing.

OSPF
That would be a distance-vector routing protocol. Examples (taught at Cisco Academies) include RIP, IGRP (obsolete in the new version of the curriculum), and EIGRP - but those are only for IP, and there are also distance-routing protocols for other networking protocols, for example, RIP for IPX.
Both uses Distance vector algorithm...... . updates the routing table for every 30 seconds. and in OSPF requires hoping reneval of routing table

Distance-vector algorithms refer to routing protocols - protocols used by routers to inform each other about available routes. In distance-vector algorithms, such as RIP or EIGRP, the routers inform each other about their routing tables, and each router adds a metric (or distance) to the route - however, the routers don't know about the topology of the network (unlike the link-state protocols, such as OSPF).
OSPF is a link-state routing protocol that helps Routers exchange IP routes. OSPF Adjacencies is the established "neighborship" between two OSPF routers in order to make the exchange of routes. In this case, Adjacency means the same as "peering", that the OSPF speakers (routers) are able to "talk" to each other.
