How are internet data transmitted ?

The Internet works largely like a telephone network. But there is a separate call on the Internet to carry data and telephone lines. When you ring a friend, a direct connection (or circuit) is opened between you and your friend on your telephone. As long as you are connected to the telephone, the circuit is open immediately. Circuit switching is a method known to connect another telephone with a telephone. The electronic telephone exchange system controls who will be heard and who will be sent.

But friends will think a little bit and understand that circuit switching is a really inefficient method for setting up a network. Whenever you are connected to your friend on the phone, you will not be able to relate to anyone on that line. (Remember, you're typing an email, typing hours, and if you can not send any mail to anyone at this time?) Think you're talking too much on the telephone or taking a long time to talk or To talk, he went to bring coffee mugs to the phone. So you are not sending any information, but then your phone is connected to your friend's phone. You are charging the bill for every second and you do not have to speak or say that the phone is connected and no one else can call it on that line. So circuit switching can never be an ideal network. What kind of internet carries data using the Internet?

Packet switching:
The Internet uses the circuits switching method to carry its data. For example, if you use Dial-Up Connection (where your computer dials a telephone number to reach your internet provider, and it works like a normal phone call) use the Internet to connect. Here you use the circuit switching method to come online. So no one can call you till I'm connected. And you have to pay for every second to stay connected. And instead your net connection will work at the turtle speed.

But most of the internet data is carried out in a completely new way called packet switching. Imagine that you want to send an email to any of your Indian friends. So here you are your Indian friend and you do not have to be connected directly to get this full mail once. After sending your mail to packet switching, it is divided into several chunks. And each of these pieces is called packets. Each packet is tagged on the face which must go to their words and they can travel to Alda Alda. When the fragments reach their destination they merge again, so that they can appear as mails.

Packet switching process is much more efficient than circuit switching method. You will never need to be absolutely connected with anyone. So you're not closing anybody's line. Anyone else can use the same line at the same time. And certain packets will reach your address exactly. Since packets reach different routes, there is no obstruction in obstruction. As a result, many fast speeds are seen.

How does packet switching work?
Before understanding how packet switching works, you need to understand how circuit switching works. Suppose you live in America and plan to come to Bangladesh. Imagine that you are thinking of getting your building up and not just with your accessories ? But think of a nightmare where you are carrying your entire house from one end of the world to another. What do you have to do?

First you have to see a road that allows you to easily travel. Then you will need some trucks. And you will need a special ship to cross the sea. Think how difficult it is to get the whole thing. And you'll be back for a few days to carry so many things together. Because your destination will be a lot of slo Again if the other person tries to come to the same street, he will also get stuck. Actually the circuit switching method works the same way. And this method is called a telephone call.

Now imagine another situation. Imagine that you took off your building and every brick numbered. Each brick stuffed the envelope and sent it on your way to your destination. Some things might have happened on the ship, maybe some of them went on the way in the sky. Then when all the bricks reached together, then the number of bricks will be created again and again the previous building will be created. Since the bricks have traveled on different roads, no street jam will be created on the street. And others can use the same road at the same time.

And just this way packet switching works. When you email or browse a site with a browser, all the data is divided into many packets and spreads over the internet.
