5.Data Encapsulation OSI TCPIP

[@Tee-e4i]

Never give up on searching on you-tube you will find the teacher that is made just for you and this one is that teacher for me

[@authman-alshibly]

I have watched many videos related to the OSI and TCP/IP MODELS topic, but this was the most explanatory one!

[@fr4nzy1113]

This vid is so clear for me no sarcasm, good explanation and no unnecessary archaic terminologies of some kind, Thank You ♡

[@lifeofhansmuller5244]

This is the best explanation I've seen so far, I just wonder why someone had to dislike this video...

[@vickysniper8346]

simply superb. Actually this guy has not copied instead he knows what he is talking. keep it up bro !!!

[@joker808dk]

Awesome! Perfect explanation I can recommend for others learning about tcp/ip and using correct terminology!

[@ruiddyyuma]

This is a simple and one of the best way to pas on information. I love it.

[@my-network9743]

i respect you from my heart. thank you very much

[@proxyiostream1511]

Thank you, finally someone could explain it clearly

[@giantjam4918]

Thank you so much for your efforts a d tutorial , i have really learned too much from them , keep it up

[@AnshumanKumar007]

10:00 in case someone only cares about TCP IP encapsulation

[@azallday5]

lolol

[@tariqal-hadyan8499]

You made it clear and simple to me, thank you very much.

[@amitshrestha1456]

Thank you so much! You made me clear about each & every thing.

[@ginoruperez]

Excellent explanation. Thank you.

[@Marcelo-gk1le]

Excellent explanation! Thank you.

[@TheDejectedangel]

Excellent job! It was explained so well that even I can understand ( - ; . Thank you.

[@thomash7247]

Very good explanation thanks !

[@arvindKUMAR1608]

Wonderful explanation, lot to take from it

[@codewithmarwan]

you are a saviour, great explaination

[@waiphyotun7633]

best explanation out there!

[@theworldisyours2241]

best explanation on the net

[@preethinatarajan6948]

Wonderful explanation

[@MaureenAlphonce]

Nice explanations,,🤗🤗

[@HenryBuild-sp6or]

Man, you have made my day !

[@junjungatbos3548]

You're the best bro. Thx!😎

[@varunsharma3485]

Best of the best

[@johnorbe764]

very informative! thank you so much!

[@ziadammouri7789]

Do you have a channel? If not you should make one. I like the way you present knowledge

[@ujammapresllc]

Exactly........

[@franceleeparis37]

Great… an OSI presentation for IT engineers rather than for school kids…. Would have been good if you explained how many bits/bytes each layer adds… presumably a frame can be 48 bits long.. but it’s a mystery..😏

[@ngoquangao9351]

Thanks a lot! Great video.

[@avengerdarkness8402]

this is so good omg!

[@randb9378]

hello, great explanation but what are some benefits from encapsulation?

[@unclewatie3099]

perfect explanation

[@DragonFlyJonez]

Thank You!!

[@weslaycock466]

I love you thank you

[@ma9pie]

Where is the number 4 video?

[@affinityarts1]

wow .amazing work

[@muhammadanandam8430]

[@fakfatkids1812]

Very nice 👍 thank you for making this

[@miyalys]

Great video! I'm curious what happens at the intermediate steps between the sender and destination. Do they "de-encapsulate" all the way up to figure out the next destination? I guess that at least some would need the Mac Address and some the IP, but maybe not further up than that.

[@chris_hawk]

From what I learned, the frames are de-encapsulated at each router so that the router can view the IP address of the destination and send the message in the proper direction (usually the next router in the chain). Since routers operate at layer 3, they are concerned with IP addresses and connecting separate networks together, while switches only deal with MAC addresses, therefore, they would inspect the frame header and send the message either to the end device or to the default gateway.

[@m.alaiady3627]

which data stored in header & trailer ?

[@calebmwaura8631]

guess am ready for my CAT now....impressive

[@nicodemusaboki4789]

Thanks so much.

[@killjaqular]

1second in; DONT YELL AT ME

[@m.mamun2020]

As I learned, In OSI Model at Application Layer, Presentation Layer and Session Layer Data is called as Data. After that at Transport Layer Data is called Segments, Network Layer Packets, Data Link Frames and Finally Physical Layer Bits or am i messing with something else?

[@sirencall1736]

my summary: data encapsulation: whenever data is transmitted between 2 devices (whenever we add a header and then send it below) each layer adds its header to the packet (control + management information) data and header tohether are called: protocol data unit (pdu) the data link layer is the only one that not only adds header but also a trailer! (except for the physical: nothing added) how does the same_layer interaction happens? it's when pc2 uses the header of pc1 on a specific layer!!

[@sirencall1736]

the header is not neccesarily made by 1 protocol, for exmple layer 4 header couls be ftp or http not pdu, but: segment: in transport packet: in internet layer frame: in data link layer

[@sirencall1736]

when talking about tcp ip model, dont say pdu! the term is SEGMENT (data+header)

[@zakariehaji]

how is the examining done what does pc2 look for

[@tijsko]

I wonder what happened to 4.OSI Model, seems to be missing from your KZbin channel. Any chance you can upload it?

[@hillmyrnarose]

I! Love! You!

[@seetsamolapo5600]

Don't mind just making myself some notes: - what is the purpose of each header of each layer in the OSI model: Each header has some control information

[@sazger]

So when data is sent, it starts at the application layer and moves down to the physical layer? Then when data is received it starts at the physical layer and moves to the application layer?

[@pipgator4271]

Yea exactly.

[@anthonyterry8162]

Makes sense to me. Thanks!

[@reoteuray9823]

what programe is used to encapsulate data ? after data is encapsulated it will travel to where ? in java have jnetpcap libary , is it to support encapsulate data , sr my bad english @@

[@davetriplett8109]

EXcellent😎

[@harounted]

thank you

[@checkmate6732]

That's a nice one.

[@haokeat7120]

looking for answer of quiz week 9

[@MrBrownpotato]

So if I'm sending an image over the network, this explanation means the image is transmitted over the wire as a sequence of bits encoding the six headers followed by a sequence of bits encoding the image and ending with the sequence of bits encoding the trailer. But this is not exactly how things work, is it? An entire image certainly doesn't fit inside a single ethernet frame, so the data must be split into multiple frames. But then where the headers go? Also, without any concrete examples it is difficult to know what these headers and data actually mean in practice, especially for the layers above the Transport Layer.

[@Wydad_forza]

I just wanna know what is this "header" thing in reality in the physical sense

[@DubsCheckum]

it's like what you use for a letter. where you put sender and receiver and stuff like that

[@armanrexlee3351]

came here because of online class

[@majiddehbi9186]

why the trailer is addede at data link thx sir for u re time Sir

[@suoyidl2654]

Never heard of Internet or Network Acess Layer...

[@suoyidl2654]

Do you mean the Network Layer a. Link Layer of the OSI Model instead?

[@tennenyt5311]

Why does every tutorial no matter when it was made have awful mic quality, that includes my university lecture videos

[@valentinionita4798]

Minute 12 when the Packet is passed down and becomes a Frame, you forgot to mention the MAC address.

[@TigeroL42]

Whole lot of gibberish.

[@fmartinez004]

please stop breathing and sighing in your mic, its annoying, thumbs down use an filter

[@defkrogeldiz3197]

Thank you for a great video!
