The development of the Internet has become explosive and it seems impossible to avoid the continuous bombardment of the www.com heard on the radio, is heard on the radio, and is seen in magazines.
Since the internet has become such a big part of our lives, a good understanding is required to use this new tool in the most effective manner.
This white paper tells the underlying infrastructure and technologies that work on the Internet.
It does not go deeper but provides enough coverage of each area to give a basic understanding of the concepts involved.

Since the Internet is the global network of computers, every computer connected to the Internet should have a unique address.
Internet addresses are in nnn.nnn.nnn.nnn where nnn should be a number from 0 – 255. This address is known as an IP address. (IP stands for Internet Protocol)
Your computer have IP address 184.108.40.206 and the second computer have IP address 220.127.116.11. Between the Internet is represented as an intangible object.
Internet service providers may be easy to guess the physical connection through the phone network, but there may be some clarification beyond that.
ISP maintains a modem pool for its dial-in customers. It is managed by some type of computer (usually a dedicated), which controls data flow from the modem pool in the spinal cord or dedicated line router. (How Does the Internet Work | Know about it right now)
This setup can be presented as a port server, as it provides access to the network. Billing and usage information is usually collected here too.
After crossing your packet phone network and your ISP’s local device, they are sent to the spinal cord buying ISP’s spinal cord or ISP bandwidth.
The Internet spinal cord is made up of several large networks that connect with each other. These large networks are known as network service providers or NSPs.
Some big NSPs are Utilities, SerfNet, IBM, BBN Planet, SprintNet, PSINET, as well as others. These networks are colleagues for exchange of packet traffic with each other.
Each NSP needs to connect to three network access points or NAP. In NAP, packet traffic can jump from the backbone of one NSP into the backbone of the second NSP. NSPs also join each other in Metropolitan Area Exchange or MAE.
MAEs provide similar aims to NAP but are privately owned. NAPs were the basic Internet interconnect points. Both NAP and MAE are known as Internet Exchange Points or IX.
NSP sells bandwidth to small networks, such as ISPs and small bandwidth providers.
This is not the true representation of the real piece of internet. This is because the spinal cord infrastructure of an NSP itself is a complex figure.
Most NSPs publish their network infrastructure maps on their website and can be easily found. To draw the real map of the Internet, it will be almost impossible due to size, complexity and sometimes changing structure.
As the protocol stack was first indicated in the section about the stack, one can estimate that many protocols are used on the Internet.
