Internet Protocol

The Internet Protocol also call an IP, is one of the system protocol by which

data is sent from one computer to another computer on the Internet. As the

Internet and technology evolve, there has been an increasing demand for IP

addresses. Each computer is known as a host on the Internet. And each

computer has at least one IP address (example: 129.41.38.1 which is an

example of an IPv4 address, commonly use) that uniquely identifies it from all

other computers on the Internet. The good news is that we don’t have to know

anything about what our computer IP means in order to use network devices.

For example, our laptop and phone use IP addresses, but we don’t have to deal

with the technical side in order to make them work.

 

However, it is also good to learn how the technical side of our computer work,

how for example two devices (Laptop, Cell Phone, Desktop, TV, Radio…) can

communicate through a networking system(cabling, hub, bridge, switch,

router, WiFi).

              The main purpose and task of IP is the delivery of datagrams from the

source host to the destination host based on their addresses. To achieve this,

IP includes methods and structures for putting tags within datagrams. To

better understand this, let us think of an analogue with the postal system. IP is

similar to the U.S. Postal System in that it allows a package (a datagram) to be

addressed (encapsulation) and put into the system (the Internet) by the sender

(source host). However, there is no direct link between sender and receiver.

Routing is one of the main functions of the IP protocol. And it consists of

forwarding IP packets from source to destination machines over a network,

based on their IP addresses.

 

An IP is just one type of protocols the Internet and networks use to

communicate. There are dozens of other protocols that are also used for

communication between other programs and devices (SMTP, HTTP, Telnet,

NetBEUI, FTP, SSH, TCP, UDP, IMAP, Apple Talk, ICMP…). For example, SMTP

(Simple Mail Transfer Protocol) is a protocol used to send e-mail from one

computer to another computer. FTP (File Transfer Protocol) provides a

method for copying files over a network from one computer to another. It is an

old protocol and is used less than it was before the World Wide Web came

along. Today, it is primary use is uploading files to a Web site.
