It explains how data is transferred across networks, the role of IP addresses in identifying machines, and the function of different layers in the internet protocol suite. The video also touches on application layer protocols like HTTP, FTP, and DNS.

  • TCP/IP is a main protocol for internet communication.
  • IP addresses are crucial for identifying machines on the internet.
  • IPv6 was introduced to overcome the limitations of IPv4 address space.
  • Transport layer manages data segmentation and reassembly.
  • Application layer protocols like HTTP, FTP, and DNS serve specific functions.

Introduction to Internet Protocols

The video introduces the concept of internet protocols as standards that different machines on the internet must follow to communicate with each other. It encourages viewers to subscribe for more content on internet connectivity and networking.

TCP/IP Protocol

TCP/IP is highlighted as one of the primary protocols used for communication on the internet. The discussion touches on transport layer functionalities and the use of different applications. For web browsing, TCP is used, while file transfer utilizes active protocols. The importance of data transfer from one place to another via wireless or wired mediums is emphasized. The process of converting data into electrical signals or light signals for transmission through various media like optical cables is also mentioned.

Internet Layer and IP Addresses

The internet layer is responsible for connectivity, ensuring that data reaches its destination by routing information between computers using IP addresses. Each machine has a unique IP address that allows for communication with remote machines. The internet layer determines the path for data to reach its destination and return. IP addresses are crucial for identifying machines on the internet, enabling the delivery of information to the correct recipient.

IPv4 and IPv6

The video explains that initially, the internet used IPv4 addresses, which are 32-bit addresses. However, IPv4 has limitations in the number of unique addresses it can provide, with a maximum of around 4 billion addresses. To overcome this limitation, IPv6 was introduced, which uses 128-bit addresses, significantly increasing the address space. Both IPv4 and IPv6 are currently in use.

Transport Layer Protocols: TCP

The transport layer is discussed in relation to the internet layer, focusing on how data is segmented and transferred. When a webpage is accessed, the transport layer breaks the data into smaller segments for efficient transfer. TCP (Transmission Control Protocol) is used to ensure reliable and ordered delivery of data packets. TCP guarantees that packets are received in the same order they were sent, providing a reliable connection, but it also has some overhead.

Transport Layer Protocols: UDP

In scenarios where speed is more critical than reliability, such as video streaming, UDP (User Datagram Protocol) is used. UDP allows for some disruption and does not guarantee the order or completeness of data delivery.

Application Layer Protocols

The application layer protocols are used to decide how applications communicate over the network. HTTP (Hypertext Transfer Protocol) is used for web browsing, and HTTPS (HTTP Secure) is used for secure web browsing. FTP (File Transfer Protocol) is used for transferring files. Additionally, protocols related to email and DNS (Domain Name System) are mentioned. DNS is responsible for finding the IP addresses of websites. When a user types a website name, a request is sent to a DNS server to find the corresponding IP address.

0:00 In this article we will add about internet protocol. There are internet protocols. Now internet marketing is different types of machines which are set up in different ways and if they want to communicate with each other then they have to follow their standards. So in a way we have to drop a text like cricket in a video. So for internet connectivity subscribe our channel. TCP IP is one of the main

0:46 protocols which is used for communication on internet. If we subscribe in fact networking course but now we try to subscribe one more time then internet protocol and let's do a small thing. But mostly we have a link to

1:32 play in which we can have net messages. If you have n't done it then please have a mobile phone or hate internet on it where our subscribe and networking related questions can be written on it. So we have transport layer

2:17 subscribe. Now we will switch on different types of applications on it. In this way for wrap we will use tcp for file transfer. For this we will use active protocol which does not have any side effect passport coach, we use that application, the latest report is that after the tester link and after that specifically we are responsible for transferring the information over and that medium to the wireless medium, this can happen to you if - that you have server transfer

3:03 and you need information through the wireless medium, the main thing is that the data is going from one place to the same place, so the link is possible, so converting that tractor into the previous difference and how that electricity or we have through the page or we have through the signals of light, if we have optical cable, then it will be transmitted over the medium, in this we also have an important thing of executing that on the link share we can produce that if a packet has come to the chandelier then the information has come, now we have to be reliable, it is not in gender discrimination, above this we have internet layer and it is basically

3:48 responsible for connectivity that our one computer Of IP address and we want to do a main gate with a remote machine, in that the remote machine has its own IP address, so what we should do with the internet players is that we should feed that part that will be responsible for which route the information that we have will reach our destination and then from there the information is coming back home, so for that also I have an internet layer, which responds to receive that information because the most important thing inside the internet layer is we have an IP address,

4:34 IP address is very important to terminate on the internet, it is through the IP address that we get to know that to which machine we have to send the information, initially inside the internet we were showing the path and by dividing it in Bigg Boss, so this sample IP address will be more people, so we

5:24 can do this network very well which is my plus The limitations of 32 bit IP address were that the maximum you can sign is in tourist places and this is with us, the retained Pintu alias Ballia Express of this type, so you cannot have more than that address, now in this way if we talk about talk about internet thanks, inside this we had even whoever you are taking in this dress, we have pimples Shesha, we also have our own questions from the potency test, so now we have limitations there and many these ipv4 addresses so that again here one button cannot limit the fact, so to

6:12 reduce this limitation, then Idea TV has six pieces that were proposed and now both the pieces are in the panel and you subscribe to this channel, we have dress power 128 subscribe behind now we will start doing 138 in this in the same way we will do egg white that from sixteen point now we would make 360 ​​feet that we would have a We create a computer that we have a passcode above the internet layer and we have a protocol related to it, the

6:57 MP transport layer is attached to it so that when we paste a separate cell, then if we do that, then we will not get the entire webpage in the form of a file, if there is an opportunity, it will break it up * Shift [ __ ] transfers can be done in the Molar pot, specific transfers can be done, from the subscriber to you, you can get the information you want,

7:49 now score in order to send that subscribe, we have a PC and we have a written guarantee of its painter, the data is sent to the hotel, we receive it in the same order, whatever packets we send to the server side, we have the same number of packets on the right side and in the same order we send it, the protocol is on its lips, but

8:35 it has its own overhead duck that when we set up on a website, we want to download any file, then inside it we will definitely have a PCO, but at times I do not need now this spoon Fennel sequence and destruction of completeness of if you are making a video now if you have a little start in it then subscribe 101 share and if you get a little option then it becomes so this is where we will

9:24 use some disruption in between we will use application protocol to decide subscribe Quanchou request came that it will come in the sperm of MP so at the application level which is related to on protocol and we have hyper text transfer protocol apart from this for secure inspection I have word protocol by using both of these we can do city SP that which is text and we have chop pass of parts which is happening by going to the website we can transfer that channel apart from this we have application double protocol activities for

10:11 piles together we have stall amazing this protocol is related to email that and then we have a domain name system responsible For all the findings of the IP address of the website, in this way if we write about the corrupt party then we have to send a request that a machine should not know its interest, till then it is responsible for the white color subscribe to
