Human intelligence knows no limits when it comes to advancing technologies. One of such inventions is the internet. Now we cannot imagine a world without the INTERNET. The power of Internet communications and access is very well known to us by now. From pigeon messengers to optic fiber and wireless connectivity overseas, man has come a long way.
The concept of the internet seems easy to you just type, google search, send and receive. But behind the scenes of the internet are incredible. You would really want to dive in. What strikes your mind is how the internet exactly works? Here is an article for you to know the working of the internet.
What is the Internet?
The internet is a connection between all the computers worldwide. The computers are connected within the same configured internet, which helps in learning and communication via information available. The computers use standardized protocols to share and communicate from any part of the world. The data transferred over the seas through the internet has to follow communication protocols like TCP.
When data transfer networking between two ends, the information is enclosed in packets that run across the connected computers. The internet is a secure place, and no third-party intervention is allowed while transmitting data.
The internet does have some loopholes, which hackers take advantage of to rob users’ confidential data. To prevent these mishappenings, the internet is a web designed with protocols that are to be followed by every receiver and sender.
1. Types of Internet Protocols:
FTP– The file transfer protocols used for transferring loads of files across the Internet. This type of protocol involves enormous data files, data sheets that flow safely from computer to computer. Many sites that offer downloadable applications use the FTP protocol.
File retrieval protocols– This type of service was one of the earliest ways of retrieving information from computers connected to the Internet.
TELNET-This type of protocol requires particular types of software to use it. This allows remote computers to use the other big servers’ computers into your own host machines.
2. Components of the Internet:
- Hardware: The hardware includes cables, routers, modems, cell phones used to connect the internet devices. The optic fibers are robust transmission lines that allow the speedy transfer of data packets via an internet connection to your homes and workplaces.
- Softwares: Every individual computer has got pre-installed, configured software. This software includes protection from third-party invaders, checking the data transferring keys from sender to receiver. Make the process of data transfer flexible and secure.
- Senders and Receivers: The sender is one who initiates the line of the transfer. The data can be of a type such as media files, encrypted data, work files, pictures, and messages through messaging apps, etc.
The one who gets the data from the sender is called the receiver. There is end-to-end encryption between every denser and receiver. The receiver confirms the identification key of the senders’ data and accepts it. If the receiver does not identify the data packets, the data is discarded or considered false data.
The Workflow of the Internet:
The Internet has become an indispensable part of our lives. Above mentioned components work in a specific manner to perform the information trade among the users. Internet connections are accessible in some cities, and in some, you will have to pay for the connectivity. The internet works with intern protocols, which ensures the data transfer is secured and fast.
The data transferred over the internet is known as the message. Any information to be shared or received is broken down into small packets to transfer with ease. These packets have accurate information or, let’s say, the message. These packets ensure the safety of data, and each packet is uniquely identified. These packets are taken care of by the protocols. The protocols prevent data loss and packet disruption by other parties.
Every device has its identification known as an IP address. These addresses help identify the servicer for packet transfer. The sender and receiver IP addresses work like source to detention identification. When you surf over the internet, search for some information your device often refers to as a client connected to the web servers.
The client devices can be your computer, phones connected to cellular networks, and servers are computers containing web services, webpages, etc. The web service providers send the client’s requested URL of websites to servers, and after accepting the request, the webpage copy from the server is displayed to the clients for use within the secured services. The 200 ok is sent on approval of the client’s request. Otherwise, the 400 error is shown on the client’s website. Each web page on the internet is safeguarded with certificates.
Conclusion:
Everything comes with its own advantages and disadvantages. The use of the internet is increasing day by day. Not only is the young generation addicted to its uses and features, but every age group is undoubtedly somehow engaging themselves with the internet connection. Even if the human brain has no limitations in reaching the heights of advancements, it is necessary to keep a hold of your internet activities.
