CONCEPT OF INTERNET

As the internet turns 50, experts weigh future advances and emerging issues | Network World

The INTERNET is a ‘network of networks’ that links computer systems around the world . It allows communication across networks , i.e., communication can take place between one network and another . This allow people to have access to information from different Web sites , locations and machines . It virtually makes accessible a sea of information and a nearly worldwide audience at the click of a button.

It was the Sputnik’s launch and the subsequent cold war , space race and the development of ARPANET (Advance Research Projects Agency NETwork ) in 1950 , that led to the establishment of the internet. However , it actually gained momentum in the 1980s when ARPANET was used by the National Science Foundation to connect the five supercomputers at its regional centres . Thus emerged a high speed Internet service that enabled access to many universities , networks , bulletin board systems , commercial online services and institutions . The decade closed with the introduction of the World Wide Web or WWW , which proclaimed the emergence of an independent platform of communication that was further augmented by a relatively easy-to-use and pleasant graphical interface .

Important Features

Some of the facilities that are available on the Internet are as follows :

  • World Wide Web : The Internet application that is currently drawing maximum attention is the WWW . It has dramatically influenced the online world and continues to grow in popularity .
  • Direct Communication : Through e-mail , messages can be sent to or received from any part of the world within a few minutes.
  • Round-the-Clock Availability : Information on the Internet is available to users 24 hours a day .
  • Wide Area Networks : Using the Internet , organizations can collect and compile information from offices spread over large geographical areas .

Internet For Students And Children

We live in the age of the internet. Also, it has become an important part of our life that we can’t live without it. Besides, the internet is an invention of high-end science and modern technology. Apart from that, we are connected to internet 24×7. Also, we can send big and small messages and information faster than ever. In this essay on the Internet, we are going to discuss various things related to the internet.

Reach of Internet

It is very difficult to estimate the area that the internet cover. Also, every second million people remain connected to it with any problem or issue. Apart from that, just like all the things the internet also has some good and bad effect on the life of people. So the first thing which we have to do is learn about the good and bad effect of the internet.

Good effects of the internet mean all those things that the internet make possible. Also, these things make our life easier and safer.

Bad effects of the internet mean all those things that we can no longer do because of the internet. Also, these things cause trouble for oneself and others too.

You can access in any corner of the world. Also, it is very easy to use and manage. In today’s world, we cannot imagine our life without it.

Uses Of InternetFrom the time it first came into existence until now the internet has completed a long journey. Also, during this journey, the internet has adopted many things and became more user-friendly and interactive. Besides, every big and small things are available on internet and article or material that you require can be obtainable from internet.

Tim Berners-Lee can be called one of the main father of internet as he invented/discovered the WWW (World Wide Web) which is used on every website. Also, there are millions of pages and website on the internet that it will take you years to go through all of them.The Internet can be used to do different things like you can learn, teach, research, write, share, receive, e-mail, explore, and surf the internet.

Convenience Due To Internet

Because of internet, our lives have become more convenient as compared to the times when we don’t have internet. Earlier, we have to stand in queues to send mails (letters), for withdrawing or depositing money, to book tickets, etc. but after the dawn of the internet, all these things become quite easy. Also, we do not have to waste our precious time standing in queues.Also, the internet has contributed a lot to the environment as much of the offices (government and private), school and colleges have become digital that saves countless paper.Although, there is no doubt that the internet had made our life easier and convenient but we can’t leave the fact that it has caused many bigger problems in the past. And with the speed, we are becoming addict to it a day in will come when it will become our basic necessity.

Is the internet software or hardware ?

To come to some conclusion first we need to know about how the internet originally came into the existence, how it works, how we people are evolved with it, and then we are able to decide/answer the very question – is internet software hardware or what??

ARPANET ‘s initial logical map

The need…

Way Before the internet we know today there was a precursor ARPANET. ARPANET was funded by the US defence department to connect all research institutions and colleges through a big wire. by using this they can transfer or interact with each of these institutions very easily and fast. it was a really big breakthrough in computer or world history! later this tech was shared with many big companies later this network becomes so big that we now call it the internet! but in 1990 ARPANET stopped and the internet was unaffected by it ( tells how big internet became).
With time we have seen many advancements in tech too with lay down the path to normal users and made all this infrastructure so feasible that even a normal household can have a connection with the network, thanks to the introduction of WIFI and win98 in the 90s.

we and our peripherals all connected with internet today

Internet and us: today

When we entered the 21st-century internet started becoming a big deal started using in many sectors and helped professionals even students! with tech it impacted on our lifestyle too, from space exploration department to personal AI in our phones …all this developed with help of the internet! millions of developers/contributors around the world contributed to making it in reach of every human! In the 2000s nearly 6.5 % of earth’s population was using the internet ( which is HUGE ngl) but this number became 50.8%! in 2018 and still growing at a faster rate than before too! when we talk about the internet and its working we think of few things like phone or pc which connected with WIFI/broadband network then that WIFI connected with some wire (ex.- fibre wire) coming from ISP(in case of broadband, it connected with some tower initially then ISP) …yeah that’s it, until which we able to visualize .. let us see this and understand in more detail.

world shares one big network

It’s all connected …

Internet is very much the same as it was in ARPANET days. different system(ex- computer) connected with one common server which acts as a message counter aka help connect each other . back then all this connection used to happen only through wires but now we have wireless modems/routers which help us connect with the same network at on close range ( so no need to connect each of them with different wire !) . so communicate with others we need to identify each other by something unique name to all here comes IP addresses and make it happen some rules introduced called TCP. When ARPANET decommissioned and the internet growing rapidly to different nations connected through the big wire ( all way from oceans ) WorldWideWeb was introduced at the same time. through the browser, we can connect with all these IP addresses and request for things ( like this blog itself!) but as you noticed IP address look very different and numeric but what we use is are in more readable. this is because of DNS protocol all IP addresses have some word associated with them like http://www.facebook.com is associated with 69.63. 181.15 IP  address


From the user side( called client ) when we enter some URL / website our HTTP request for that website goes to ISP(Internet Service Provider) then DNS servers identify the IP address and where that website is stored, yes you heard it right! websites are files just like your word or excel ones and similarly, it stored somewhere someplace ( called data centers ) . so this HTTP request rhea there and all this info comes to you all the way from there in packets and tada! Each and every website works like these even video ones where the same packets come… in the case of live interaction it comes continuously. These data centres/web servers are a bit different they are not connected with the internet as your client one is through isp but they are connected with the internet network directly!

SO… is it ?..

Now the big answer time! The answer is as you already figured out reading all this.. Internet is a mix of both!

The Internet consists of many interconnected networks. Those networks are composed of hardware and software. The systems connected to the network must have hardware network interfaces, which are either wired or wireless. Software is required to regulate those interfaces, to compose, send, receive, and decode packets of knowledge using several standard protocols. Routers, switches, firewalls, and other devices are required to attach systems and networks together. a number of these devices are purely hardware, but many perform some level of processing, which needs that they contain an embedded computer running software. The systems connected to the network also typically have some type of package running on them, and a software system is a software. Web servers, management systems, web browsers, web-enabled applications, etc. are all required likewise, and people are all samples of software.

So, the net consists of both hardware and software
