Internet Protocol (IP)

 }  Internet Protocol (IP) is the principal set (or communications protocol) of digital message formats and rules for exchanging messages between computers across a single network or a series of interconnected networks, using the Internet Protocol Suite .

}  Messages are exchanged as datagrams, also known as data packets or just packets.

}  The main purpose and task of IP is the delivery of datagrams from the source host (source computer) to the destination host (receiving computer) based on their addresses.

}  The most prominent component of the Internet model is the Internet Protocol (IP). IP enables internet working and, in essence, establishes the Internet itself.

}  ·  The Internet Protocol (IP) is the method or protocol by which data is sent from one computer to another on the Internet.

}  ·   Each computer (known as a host) on the Internet has atleast one IP address that uniquely identifies it from all other computers on the Internet.  Two versions of the Internet Protocol exist, IPV4 and IPV6.

}  ·   IP has the task of delivering packets from the source host to the destination host solely based on the IP addresses in the packet headers.

}  For this purpose, IP defines packet structures that encapsulate the data to be delivered.

}  Definition: The Transmission Control Protocol (TCP) is a core protocol of the Internet protocol suite. It originated in the initial network implementation in which it complemented the Internet Protocol (IP). Therefore, the entire suite is commonly referred to as TCP/IP.

}  The TCP/IP model, and hence the Internet, is based on two structures, one for the data being transmitted and the other for the routing computers that would make up the core of the network:

}  Data is broken down into smaller packets for transmittal through the network.

The Network is essentially composed of a number of routing computers (or routers) that route the packets towards their destination computer by passing them to the next router that is
