That means that if an IP packet is sent, there is no guarantee that it will arrive. If it doesn't arrive, IP will do nothing to re-send it. If it is necessary to re-send lost packets, higher-level protocols (usually TCP) take care of that.
No TCP a reliable protocol whereas UDP is unreliable.
The IP protocol creates all IP packets.
IP stands for Internet Protocol and it is is a numerical label that is assigned to devices participating in a computer network that uses the Internet Protocol for communication between its nodes.

The protocol field, in the IP header, identifies what kind of data is in the IP packet - the upper-layer protocol. For example, if the code is 6, that means that the data is a TCP segment.

Internet Protocol (IP)
ANSWER According to W. Richard Stevens's book, TCP/IP Illustrated, Volume 1, UDP stands for User Datagram Protocol. It is unreliable, in the sense that there is no retrying defined in the protocol. This is in contrast to TCP, which stands for Transmission Control Protocol. TCP creates a connection layer on top of the unreliable Internet Protocol (IP), by retrying the transmission of sequence-numbered packets so that the receiver can correctly reconstruct the data as it was sent. UDP just transmits the packet, and if any attempt at guaranteeing that a packet was received is needed, it must be done by the application level, not at the protocol level. Note that although it seems like an application should never use an unreliable protocol, the overhead involved in creating TCP connections is often deemed unnecessary, especially for operations done on LANs (ARP, BOOTP, etc).

IP means Internet Protocol
A "protocol" is a set of rules used in networking, for a particular purpose. IP (the Internet Protocol) is the protocol used to transmit packets over various networks.TCP (the Transmission Control Protocol) is the protocol which (among other things) ensures a high degree of reliability over inherently unreliable networks. That is, individual IP packets may be lost, but TCP ensures that they are retransmitted. TCP/IP is a protocol suite - in other words, a group of related protocols. It is named after two important protocols, explained, above, but it actually includes various other protocols as well.
TCP is a sub-protocol within the IP protocol. Think of TCP as one of the instruments in a band.
TCP-IP is a protocol, not a transmission medium. Bandwidth doesn't affect it.
