Venom, or the Venom Symbiote, is a sentient alien Symbiote, with a gooey, almost liquid-like form. It requires a host, to bond with for its survival. When the Venom Symbiote bonds with a human, that new dual-life form itself is also often called Venom. The Symbiote's first known host was Spider-Man. Its second host, Eddie Brock, went on to become the villain, Venom, one of Spider-Man's archenemies.
