IPX, IP, and NetBEUI - Network+ Certification Tutorial

IPX: Internetwork Packet Exchange. IPX is a Novell designed protocol which has packet sizes of approximately 1500 bytes for Ethernet and 4KB for Token Ring. Performs addressing and routing functions. Resides in Network Layer. Requires some configuration.

IP: Internet Protocol. IP was based on two models, the DOD Model (4 layers) and the OSI Model (7 layers). IP was designed by the DOD for ARPAnet. IP is the default protocol for Windows NT and Unix during installation. IP is a connectionless protocol responsible for addressing and routing packets between hosts. IP functions at the Internet layer in the DOD model and on the Network layer in the OSI Model.

NetBEUI: NetBIOS (Network Basic Input Output System) Enhanced User Interface. NetBEUI is a Microsoft designed protocol for fast packet delivery on small networks. It is not routable, but doesn't take much configuration. It operates on the Network and Transport layers in the OSI Model.
