| connection oriented protocols | protocols that require a host establish a connection or session before information can be transfered. Also called stateful protocols, they are more reliable |
| connectionless protocols | protocols that do not require a session be established; they rely on the best effort. Aso known as stateless protocols |
| routable protocols | protocols that can pass through a router. TCP/IP is an example of this protocols |
| nonroutable protocols | protocols that use predefined, or static routes that cannot be changed. Examples are LAT and DLC |
| TCP/IP | the defacto standard for LAN and WAN, used as the primary or sole communication protocol on nearly all new computer network installations. |
| Transmission Control Protocol TCP | protocol that ensures reliable communication and uses ports to deliver packets, connection oriented,fragments and reassembles messages |
| Internet Protocol IP | connectionless protocol responsible for providing addresses of each computer and performing routing |
| User Datagram Protocol UDP | connectionless protocol that allows information to be sent without using a handshake process |
| Internet Control Message Protocol ICMP | this protocol is included in IP and is used for troubleshooting connectivity between systems as well as sending error control messages between routers and switches |
| IPX/SPX | a protocol suite rather than a single protocol developed by Novellsupported by Unix systems. |
| Internetworking Packet Exchange IPX | connectionless protocol that resides at the network layer and is responsible for network addressing and fowarding packets to their destination. Similiar to IP |
| Sequenced Packet Exchange SPX | connection oriented transport layer protocol that ensures that packets arrive intact at their destination and provides reliability to IPX. |
