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.
