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

I love this guy, he makes it look so easy

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.

Great video. Thank you for the clear explanations

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

[alesrx]

Salut Professeur! La video est excellente! Merci beaucoup !

[simonmcgraw]

thanks Sunny! I really like this stuff

[Brian-nzns]

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...?

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?
