7 parts of an Ethernet Frame

In plain English, a frame is a data packet or a data unit. Technically, a frame is a protocol data unit or PDU at the data link layer of the OSI model. The PDU at the different layer of the OSI model is named differently.
At the transport layer, for example, the PDU is called a TCP segment or a UDP datagram. Most applications use TCP, and thus a segment is often used to represent the PDU at this layer. At the network layer, the PDU is called a packet, or an IP packet. At the data link layer, the PDU is called a frame.
Different TCP/IP technologies use different frames in terms of the header information, and the maximum transmission unit of the data, or the payload capability.
An Ethernet frame has seven main parts: preamble, recipient MAC address, sender MAC address, type,data, pad, and FCS.

I like Sunny videos because even though this stuff can be really complicated to understand...he makes it easy too understand and the end music makes u feel good :P

[@sunnyclassroom24]

Thank you for watching!

[@davemcarthy8471]

I love this guy , he makes it look so easy

[@sunnyclassroom24]

Thank you a lot.

[@zes3813]

no such thing as easy or ignorex or lx etc, any infix relatex any nmw

[@0128501221]

I just wanna tell you something, I have watched many videos and done a lot of thing but unfortunately, I didn't get anything, after watching your video I did got it, and for the first time I found it understandable, so thanks a lot for your efforts and keep going, you're such an spectacular teacher.

[@yournamehere5554]

doing the google it support cert and someone tried to explain this for an hour and couldnt grasp it but this took 4 min, thanks a lot from Sweden

[@Alex-hu8gj]

Finally a good frame explanation

[@robotguard614]

I'm literally writting a test tomorrow and this was perfect and on point

[@jamesj9744]

Sunny, you are awesome. Thank you for putting this information online.

[@narindermittal6772]

thanks Sunny for excellent videos. I watched each and every video. It was really helpful in my CISSP preparation.

[@sunnyclassroom24]

Thanks a lot for watching my videos. I hope they would be helpful for your CISSP.

[@taddy666]

Awesome - lots of detail that I was curious to know. Cheers dude.

[@bensonmaingi5814]

hello sunny thank you for your well presented and vividly explained videos.keep it up

[@sunnyclassroom24]

thanks a lot.

Yes he is excellent...his présentations are pédagogie,calm ,precise,funny,short but excellent...Thank you

[@sunnyclassroom24]

Thank you for your comments!

[@bhavya2301]

Thanks For This Video.Short & Understanding.Hope You Continue To Make More & More Videos.

[@asoteico9528]

Awsomely explained Sunny...!!! 🥇🎖🏅

[@theworldisyours2241]

a breezy day with Sonny. Thank you

[@jeffyneedsanap]

You made this simple to understand. Thank you very much!

[@jessepitman2994]

Great explanation

[@arunpc8789]

Very Informative..

[@alesrx]

Salut Professeur! La video est excellente! Merci beaucoup !

[@gitarooman4397]

Great video. Thank you for the clear explanations

[@kapilramanujancbse]

Hi sunny, How about a data payload greater than 1500 bytes is transmitted. So how does the fragmentation happen?.

[@Phleemflam]

Sunny you're a real g

[@faridyama97]

Very well explained, Thank you !

[@sunnyclassroom24]

Glad it was helpful!

[@faridyama97]

Sunny Classroom Respect !

[@simonmcgraw7994]

thanks Sunny! I really like this stuff

[@davidblake2344]

thank you Sunny, this helped!

[@virajmodi6353]

Thank you :)

Sonny is the best.

[@lallu1122]

amazing.... best on youtube

[@alialiraqi2664]

thank you

[@aminesemlali6199]

Best teacher !

[@sunnyclassroom24]

Thanks!

[@Brian-nz6ns]

So the Packet and Segment are inside the data portion of the frame? And the frame gets broken down into these different PDU's as it goes up the OSI model from switch to router to application, etc...?

[@itzboyon6983]

seems like it was nothing to understand. thanks Sir, I really appreciate your such great effort

[@sunnyclassroom24]

You are welcome!

[@SysTechs]

Perfect!

[@sunnyclassroom24]

Thank you for watching!

[@kungfungify]

i think im in love

[@abhijeetnikam894]

Plz make video on ldap working

[@huyintang8407]

hello Sunny thank you for your videos. I have a question about the name of the Packet. I found some books called it Datagram.

[@sunnyclassroom24]

packet is a general term. Datagram is for UDP

[@aliihsansenel]

Thank you again for another informative video, I wonder where tcp/udp packets are stored? Are they also located in the data part of the mac frames? If it doesn't how are src/dst ports are linked to IP and MAC.

[@TheKlopdokter]

tcp/udp packets are called segments which are stored in the IP packets

[@curtiswillis4454]

At time stamp 3:25 in this video, you said the minimum payload in the "Data Section" is 64 bytes. The Official Cisco Cert Guide CCNA 200-301says the minimum payload is 46 (page 50). Which is right? Does anyone else have an answer to this?

[@jbizzle1966]

Ethernet has a minimum frame size of 64 bytes, comprising an 18-byte header and a payload of 46 bytes. It also has a maximum frame size of 1518 bytes, in which case the payload is 1500 bytes.

[@jibnathgautamhy1280]

Please make a video on ppp vs pppoE

[@worldtreeboy8712]

Does a frame have/contain IP address in it?

[@silveradopunked8329]

Is this Jian Yan ?

[@Ta___]

is payload is static?

[@sunnyclassroom24]

payload is the data the frame carries. It is static in this sense. but different frame can carry different payloads.

[@Ta___]

@@sunnyclassroom24 ok sir,this question was asked during an interview,that during packet transmission payload will be static,i have replied yes,let me know i am correct?

[@Ta___]

@@sunnyclassroom24 one more question sir,why centralized system more reliable than decentralized system?

[@sunnyclassroom24]

@@Ta___ It depends. Blockchain technology is decentralized technologies, but it is reliable, like bitcoin.

[@sunnyclassroom24]

@@Ta___ but in general, centralized systems can be controlled, but what if the central point fails? That is why my answer is "it depends".

[@chrispainter3602]

Isnt a preamble of an ethernet frame 56 bits? 7 octets 8 bits each = 56 bits

[@kungfungify]

yes, 56 bits, also known as seven bytes

[@einarsdandens8961]

Hello vhat open wrong internet adress

[@kyliestaraway2492]

Preamble I am coming to u yea u coming to u and im telling u where it starts and i am 64 bits recipient mac adress i am telling where to go i am not very slow sender mac adress i am telling where i came from but u dont really have to know type i am not racist but im telling u everything about me anyway data field i carry on and on and have IP secrets 1500 bytes Pad im just fill :( and i make it fatter so it reach 64 bites just like a plastic surgeon pad FCS and im a cop i check check for errors and verify the frames

[@bensonmaingi5814]
