    They are different protocols for communication over and between LANs. Ripv2 is Distance-Vector (hop count), OSPF is Link-State (Cost), IGRP and EIGRP are Cisco propriety, and BGP is the the protocol used to exit the default gateway. Wikipedia has a lot of information on all of these.

    You'd better look them up, because I just learned them myself, and so you'll want to double check what I just said... in other words, I can't yet give you a complete and detailed answer.

    They are routing protocols. Look up routing protocol on wiki.

    They exist to help routers figure out where traffic should go. BGP is used on the internet, and the rest are used on internal networks. Without these protocols, a human would have to manually enter all of the networks the router can connect to using static routes (imagine doing that for the internet - it wouldn't work). These protocols exist so routers can share information about places traffic can go without human intervention. The ability of routers to share this information is needed to make the internet work.
