Today tips : Know about What is the Internet? What is the use of internet!

The Internet is a unique and integral part of our daily lives. It is difficult to imagine our daily life without internet for a moment. The internet has completely changed the pace of our work. The Internet has made our lives easier. The impeccable contribution of the Internet can be summed up in one sentence. The Internet is slowly becoming a blessing in disguise for our lives.

What is the Internet

What does internet mean?

What is internet?

The Internet has become a lifelong friend. But do we know what the Internet is? Who brought the Internet in front of us? Let’s not know about the internet. Internet is an English word. Originally the word Internet originated from Ethernet. The word Internet means “Internet” . The medium that connects the whole world through a network is called the Internet. The Internet has connected the whole world through a network. Today the whole world is established as a family due to the outstanding contribution of internet.

Who is the father of internet?

The Internet has changed the course of our lives, making our lives brighter and easier. There is no denying the contribution of the Internet in everyday life. We all know the benefits of this on the internet. But do we know who invented the Internet that changed the course of our lives? For this, millions of people have worked day and night to bring him to where he is today.

When it comes to Internet discovery, the names of two people come first. They are Robert E. Kane and Winton G. Curfew. These two talented people invented the Transmission Control Protocol (TCP) and the Internet Protocol (IP). These two protocols made the journey of Internet discovery easier. As established before us.

Does the internet actually work?

The job on the internet is actually very simple, he just transfers and provides data from one place to another, diameter. The main function of the machines that have come together to create the Internet is to exchange and provide data. In fact, the Internet can be compared to a postal service.

Letters are exchanged from one place to another in the Postal Service. But it doesn’t matter who the letter came from or what is written inside the letter. Again, even if the letter is completely blank, the postal service does not come. His job is to deliver the letter. The Internet works the same way.

Like the postal service, the Internet also carries a lot of information and transmits it from one place to another. This means that if any data is exchanged, the Internet will complete it. Now whether you send emails or massage someone has nothing to do with the internet. However, the task of exchanging data is the only thing that will help to complete the Internet, diameter. We are now exploring new uses based on this data exchange formula. For example, when two European investors created Skype, they brought telephone conversations into the net. They created a program where our conversations could be turned into data and conversations could continue. But it was never possible to create a separate internet for Skype by exchanging our words directly.

What is the use of internet?

Internet is the name of a word without which it is impossible for us to have a moment. At present it is difficult to think of our life without internet for a moment. It is not possible to say in one sentence what is the use of internet in our life. But not without saying something. But do we really know what the Internet is all about in our lives? Let’s find out now from the Internet of Things.

How is this internet data exchanged?

internet data exchanged

The Internet basically works like a telephone network. But carrying data on the Internet and making telephone calls is a different matter. When you ring a friend, a direct connection (or circuit) opens between you and your friend on your telephone. As long as you are connected to the telephone, the circuit is open. The method of connecting one telephone to another  is called circuit switching  . Electronic telephone exchange systems control who can be heard and who will be sent.

But if you think about it, your friends will realize that circuit switching is a really inefficient way to set up a network. No one else will be able to connect with you on that line whenever you are connected to your friend on the phone. (Suppose you are typing an email to someone, it may take hours to type, and if no one else can send you any mail at this time?) Suppose you are talking too slowly on the telephone or taking a long gap He left the phone and went to fetch a mug of coffee. So you are not sending any information then,

Packet switching

The Internet still sometimes uses circuit switching methods to carry its data. For example, if you use a dial-up connection (where your computer dials a telephone number to reach your Internet provider, and it works like a normal phone call) to connect to the Internet. Here you use the circuit switching method to get online. So no one can call you as long as I’m connected. And you have to pay for every second you stay connected. And instead your net connection will work at a snail’s pace.

But most of the internet data is carried in a completely new way called packet switching. Suppose you want to send an email to an Indian friend. So here is your Indian friend and you don’t need to be directly connected to get this complete mail at once. After sending your mail in packet switching, it is divided into many parts. And each of these pieces is called packets. Each packet is tagged as having to go their separate ways and they can travel in different directions. When the pieces reach their destination, they are reassembled so that they can be displayed as mail.

Packet switching methods tend to be much more efficient than circuit switching methods. You will never need to be completely connected to anyone. So you are not closing someone’s line at all. Someone else may use the same line at the same time. And the specific packets will reach your address just like that. Since the packets travel in different directions, there is no obstruction. As a result, many fast speeds can be seen.

How does packet switching work?

Before you can understand how packet switching works, you need to understand how circuit switching works. Suppose you live in America and plan to move to Bangladesh. Imagine that you are not only thinking about your belongings but also about your building and moving, but think of a nightmare where you are carrying your whole house from one end of the earth to the other. So what do you have to do?

First of all you have to look for a road that you can travel easily. Then you will need some trucks. And to cross the sea you will need a special ship. Think about how difficult the whole thing became. And you will go back a few days to carry so much together. Because your destination will be much slower. Again, if someone else tries to come on the same road, he will also get stuck. In fact the circuit switching method works this way. And this is how telephone calls are made.

Now imagine another situation. Suppose you opened your building and numbered every brick. Fill each brick with an envelope and send it to your destination one by one. Some of them may have gone by ship and some of them may have gone by air. Then when all the bricks have arrived together, the numbers of the bricks will be matched and the previous building will be made again. Since the bricks have traveled on different roads, there will be no traffic jams. And others will be able to use the same road at the same time.

And this is exactly the way packet switching works. When you email or browse a site with a browser, all the data is split into many packets and spread on the Internet.

How many types of internet and what are they?

many types of internet

The Internet has made our daily lives easier and simpler. We can do the work that we used to have to wait for day after day, sitting at home through the Internet. The Internet has easily taken over various obstacles in our way of life. But many of us are unaware of the types of internet. Let’s find out now from our favorite internet types.

The Internet is basically divided into 6 parts. There are 6 divisions:

  • Dial up.
  • DSL.
  • Satellite.
  • Cable.
  • Wireless.
  • Cellular.

Learn more about the types of internet:

Dial up:

The type of internet connection that is usually available from a standard phone line is called dial-up. Through this process, the internet connection to the mobile starts within 10 seconds.


DSL has come to the market due to the omission of this service due to the slowness of dial up. DSL is basically a cable connection that is 100 times faster than dial up.


Satellite is one of the examples of high speed internet service. Satellite has been able to provide maximum wireless internet service.


Broadband connection via cable provides internet connection between computer or laptop. It is very popular. A medium that is faster than any other medium.

Wireless :

Wireless is the means by which two media can communicate with each other at close distances.

Cellular :

Cellular is the mobile phone that uses the internet. This is a very popular medium.

How do computers do different things on the Internet?

different things on the Internet

There are hundreds of millions of computers across the Internet. But not all of them do the same thing. Some of these computers only store information and send it when requested. And these machines are called servers. The machines that store any documents are called file servers. The servers that hold your mail are called mail servers. And the servers that contain webpages are called web servers. There are millions of servers on the Internet.

Computers that collect information from servers are called client computers. When you enter the Internet to check mail, your computer is the client, your ISP (Internet Service Provider) is the server and the mail comes from the mail server. The Internet has more clients than servers, about a billion.

When two computers exchange information with each other, it is called peers. If you do instant messaging or photo sharing with your friends, this is peer-to-peer (P2P) communication. P2P sometimes behaves as your computer client and sometimes as your computer server. Suppose you send a photo to your friend, then your computer serves as the server (sent the photo). And your friend’s computer will act as the client (access the photos). When your friend sends a photo, his computer will act as the server (sent the photo) and your computer will act as the client (access the photo).

In addition to just servers and clients there is another medium computer which is another part of the internet. And its name is router. It just helps to connect different systems. If you have multiple computers at home or at school or in the office, the router will help you connect to the Internet.

TCP / IP and DNS:


The real thing is to exchange data on the internet but it is not as easy as carrying a house in a brick envelope. Internet data cannot be controlled by any human being like you or me. Numerous data transfers are made on the net every day — drafting nearly 3 billion emails and huge amounts of traffic downloading and uploading various data across 250 million websites around the world. Now the question is if all this data is sent in packets and if no one has any control then how can everyone get to the real destination without losing these packets?

The answer is  TCP / IP or Transmission Control Protocol / Internet Protocol . This system helps to deliver all the packets to the destination. It can be called a two-in-one system. In the world of computers, “protocol” means a standard that everyone believes in and ensures that everything is delivered. Now you must be wondering, does TCP / IP actually work? Let’s find out.

Internet Protocol or IP  is a simple addressing system. All the machines on the internet have a different IP. When each machine has a different IP, it is easier to identify which machine and which packets can be sent accordingly. IP addresses are basically a number of entries. And the numbers are separated using commas.

In the case of websites, things are a little different. Names are used on the website for easy remembering instead of IP. Such as (Techwave.Asia). The name of this system is DNS or Domain Name Server. After entering the domain name into the browser, the computer starts looking for this IP and when it finds the IP, the site opens from the web server.

There are basically two types of IP. One is IPv4 and the other is IPv6. IPv4 contains four digit digits. Such as or . It is basically made up of binary numbers but is expressed by a 32 bit numeric number for the convenience of human understanding which can be from 0 to 255 but in today’s fast growing internet world there are no new IPv4 addresses left today. So a new system has been invented which is called IPv6. It is 128 bit and much longer than IPv4. 3ffe: 1900: 4545: 3: 200: f8ff: fe21: 67cf . Here is an example of IPv6.

Another part of this control system is the  transmission control protocol or TCP . This system determines how to send packets from one IP to another. And this system aggregates the received packets. If any packet is lost while sending the packet again, it is re-sent.

Use of internet in education

The Internet is influencing our daily lives in many ways. Education is no exception. Since the invention of the Internet, the study of students has become quite easy. Let’s find out how the Internet is contributing to the field of education.

  •  Home teachers used to understand the reasons why students did not understand many things to study like before, but with the invention of internet, students are still getting the opportunity to study at home without the help of teachers.
  • If you want to know something unknown, it is very easy to know that unknown thing sitting at home for the benefit of internet.
  • As a result of internet, students are able to earn as much as they want while studying at home.
  • Sitting at home as well as the opportunity to participate in the test.
  • You can study at home as well as read books from anywhere in the world.
  • The convenience of learning one’s own unknown subject as well as spreading one’s knowledge to others is possible only through internet.

Internet access from computer to mobile Internet from mobile to computer :

At one time the Internet was used only on computers. But over time, that is likely to change. Before, the Internet could only be used on computers, but over time, the Internet is now being used on laptops. Because laptops are easy to carry, people nowadays feel more comfortable using laptops than computers. But the uninterrupted portability of mobile phones has resulted in people using the internet on mobile phones nowadays.

As a result of using mobile internet, people can easily know about unknown countries, as well as go to unknown countries and find their way using internet. Also, due to the easy availability of internet on mobile phones, people seem to be far away.

Last words:

The Internet has changed the way we live our daily lives. The use of internet in our daily work has emerged as a very helpful friend in many ways. Not too far away when our world will run on the Internet. In a nutshell – how many people can you call in one place? But it is possible to put billions of people at the negotiating table at once through the internet.
