What is the Internet?
We understand the Internet to be involved in any work online through any browser by turning on the mobile data connection or WiFi.
But what exactly is this internet thing? What does this mean?
Internet is simply being connected to a network. Connecting to a network with a computer or any device is called internetworking or the internet.
In the case of the Internet, every computer is connected to each other through a huge network. It is a worldwide network and all computers in the world can be connected to each other through the Internet.
What exactly is the internet?
Internet is basically the abbreviation of Interconnected network. The communication system that is formed by combining multiple networks is called the Internet.
The Internet is a special gateway that is formed by connecting computer networks to each other through special routers. It is also called NET for short.
It is the largest network in the world. Because you can connect to the internet from anywhere in the world through any device.
In other words, many computers are connected together to form a network, and connecting a network to another network is the Internet.
We can also call it a network of networks. Moreover, the internet is also called internetworking.
Numerous devices can communicate with each other through the Internet, and thus we have the entire world at our fingertips, sitting at home.
What is internet money?
The full interconnected network of the Internet is an Inter-connected network in English.
In Bengali, it is called Antarjal.
The word Internet consists of two words. Inter means inside and net means net.
That is, the main meaning of the Internet is the intranet or the inner network.
Moreover, the Internet has more meaning. The abbreviated Internet is called as Net.
How the Internet Works.
We have already known or come to know what the Internet is.
But have you ever asked your mind how the internet works?
You might think that the Internet probably works via satellite. But you are lying.
98% of Internet communication in the world is through Optical Fiver.
Computers or devices scattered around the world connect themselves first through various types of local area networks.
There are different types of Local towers to connect to the local network.
These networks of local computers are later connected to each other with the help of another network and that network is the Internet. It works through the undersea optical fiber.
Explain how the internet works.
Let us explain to you how the internet works with a small example.
The device with which you are browsing the Internet is first connected to an ISP (Internet Service Provider) or an Internet service provider through its own modem or LAN.
Here, various sim companies or Wi-fi Broadband companies receive services from internet service providers or ISPs.
That ISP is then connected to a larger ISP.
Now the question comes of how the ISP connects to another larger ISP.
Here comes the talk of Optical Fiver.
A country's ISPs are connected to other countries or larger ISPs through a fiber optic backbone.
An optical fiber or fiber optic backbone is a thin transparent glass cable that connects one country to another through the seabed.
Countless information or signals from each computer are constantly being sent from one place to another through this optical fiber. This is how the Internet works by sharing information.
And this exchange of information happens within the blink of an eye.
This is basically how the Internet communicates from your computer to the IPS, then from the IPS to the larger IPS, then back to another computer or server.
This is how networks are built. And the Internet spread worldwide. This is basically how the internet works. This is how the Internet has created a web of networks all over the world and has brought the world into our hands.
What is an internet server?
You already know what the Internet is and how the Internet works. Internet is basically a special gateway through which one computer is connected to another computer.
The Internet works by exchanging information from one computer to another.
Now the question is what is the Internet server?
The Internet service is a special type of computer that only collects data. Whenever a computer needs to know any information, if it requests the server, the server displays the information by responding.
As such, our website is hosted on a hosting server. Now if any computer wants to enter our site then it has to write the address of our website and request the server.
And the server in it will display our website to you. Thousands of such data are stored in different servers.
Anyone can connect to the internet and make server requests.
What is Arpanet?
In 1960, the US military's Advance Research Projects Agency (ARPA) experimentally developed a communication system between some universities and laboratories in the United States.
This packet switching network was known as ARPANET.
This quality has 2 parts.
One is ARPA by which an organization is known. And the word NET stands for the flame which means communication system.
It was then called ARPAnet because this communication was restricted to the US military research agency ARPA.
But when it started spreading worldwide, it was named the Internet.
What are the types of internet?
The Internet can be of many types.
Internet in the overall sense is of 2 types. Namely:
- Online Internet
- Offline internet
But based on usage again 6 types of internet are known.
They are 1. Dial-up 2. DSL 3. Satellite 4. Cable 5. Wireless 6. Cellular
The Internet was invented in which country?
The first network communication was established between the University of California, Los Angeles, and the Stanford Research Institute.
So we can say that the internet was first discovered in the United States or America. The first name of this internet was ARPANET.
It was named Internet in December 1974.
In what year was the internet invented?
The Internet was first discovered on January 14, 1969. At the beginning of its discovery, it was called ARPANET, but later it was named the Internet in 1974.
In fact, the Internet was not invented in a day.
Therefore, it is not possible to specify the time when the internet was invented.
But it is believed that during the post-World War II US-Soviet Cold War, the USA created a computer network for its military as an alternative to telegraph telephones in order to ensure that their communications system would not be completely destroyed in the event of a possible war.
They named it 'MILNET'.
It later evolved into the ARPANET and the Internet.
However, the year of discovery of the value of the Internet is considered to be 1969.
Who invented the internet first?
The inventor or father of the Internet is called Vinton Gray Cerf (Vinton Gray Cerf).
But actually, the inventors of the internet are Bob Kahn and Vint Cerf
Vinton Gray Cerf was the co-inventor of TCP/IP. While working at DARPA, he played a major role in the creation of the Internet.
When did the internet start in Bangladesh?
The Internet was launched in the world in January 1969.
But, internet usage in Bangladesh was introduced in late 1993.
And it was opened to the public in Bangladesh in 1996.
In late 1993 some local service providers introduced a system called the Bulletin Board System (BBS).
In this way, they created the opportunity to use e-mail with the help of dial-up.
But there was a problem that more than 500,000 users did not have this facility to use email.
As a result, in 1995, the internet was first used in a limited form in this country through offline e-mail. And it was completed in 1996.
In 1996 Vista was first installed for the internet in Bangladesh.
And online Internet connections began to proliferate through an ISP called ISN.
It is good to know here, that the full form of ISP is Internet Service Provider which means Internet service provider.
Although the online internet in Bangladesh started in 1996, the number of mobile phone users in the country was low.
History of the Invention of the Internet
You have already known what is the Internet and what is the Internet called and what are its functions.
But know the history of the invention of the Internet?
In fact, the invention of the Internet began in the 1950s with the advancement of electronic computers.
But when a message was sent via Arpanet from the University of California to the Stanford Research Institute, the public was first introduced to the Internet.
In the late 1960s and early 1970s, Arpanet was further developed using packet switching networks or protocols.
It was further expanded in 1981 when the National Science Foundation (NSF) and the Computer Science Network (CSN) developed access to the Arpanet.
Later in 1982 the word "Internet" was used for the first time.
Commercial Internet Service Providers (ISPs) began to emerge in the early 1990s. Since then, optical fiber cables have been laid under the sea, providing Internet connectivity from one country to another.
In this way, internet services spread all over the world and we can easily communicate from one country to another through the internet while sitting at home.
Today in 2021 we can run the internet at 5g speed.
Maybe it will improve more as technology improves.
What is the number of internet users across the country?
How many people use the internet?
As of January 2021, there were 4.66 billion active internet users worldwide which is about 59.5 percent of the world population.
Of this total, 92.6 percent or 4.32 billion use the Internet through mobile devices.
What is the number of internet users in Bangladesh?
How many people in Bangladesh use the Internet?
There were 47.61 million internet users across Bangladesh in January 2021, an increase of 7.7 million or 19% from 2020.
Internet penetration in the country was 28.8% in January 2021
Why do you have to pay if you use the Internet?
We all use the internet.
You have to spend money to buy data to use this internet.
Ever wondered why you have to pay to use the internet?
Actually using the internet does not cost any money.
Information is transmitted freely from one place to another through optical fibers under the seabed.
So why do we spend behind the Internet?
Companies that lay optical fiber under the sea and submarine cables have to pay for the cost and maintenance of the submarine cables.
The cable they built the internet with is constantly charging people for the cost of the cable.
Moreover, these cables are repaired with the internet money received from people.
The Internet has brought the world to our fingertips.
We take the help of the internet in our daily life.
It can be said that we don't have a single moment without the internet. Because this internet has many advantages.
Some of them are mentioned below:
The internet has made it easy for us to communicate. Now you can directly video call anywhere in the world while sitting at home.
Moreover, conferences of different countries are also conducted through the internet.
The Internet has really given an incredible shape to the communication system.
The Internet is also called a repository of information. Because all known and unknown information is stored on the internet.
Whenever someone needs to know any information, after browsing the internet, he can know the information instantly.
Before the invention of the Internet, television was the only form of entertainment. Then you had to sit and wait for something interesting to watch on other televisions.
But, since the invention of the internet, we can search for any type of entertainment at any time.
Moreover, there are Facebook, YouTube, and Twitter as social media for entertainment.
Playing online games using the internet can be one of the ways to pass the time.
Now we can play online games at home connected to the internet, and see other's score, profile and activity.
It can be a means to pass the time and enjoy the time.
But be careful that you and your child do not get addicted to online games.
In today's age, you don't have to go to the office to get a job or office work. Rather, any office work can be done at home.
This reduces travel expenses and office expenses.
There are thousands of e-commerce websites on the internet, just like bazaar stores in the digital age. You can order various products from these websites at home.
And after ordering and paying, the company will deliver the ordered product to your home.
This is an extreme advantage of the Internet you might say.
The Internet has changed the life of many unemployed boys.
Many people now make money using the internet.
They choose youtube, blogging, online marketing, freelancing, etc. as their livelihood.
Newbies Freelancers Earn Money Online Through Fiber. Again blogging can earn a good amount of money every month.
Blogging is actually a way to earn money by creating a website.
Asha Rakhi got to know what is internet and many things about the internet. Without the internet, our lives would have been extremely difficult in the present age.
So we should give credit to the invention of the internet.
A request to you is don't abuse this internet. And be safe from various fads.
