What is Ethernet ?
Ethernet is the name of LAN standard defined by IEEE 802.3. It was basically introduced as a LAN technology.With the introduction of Gb Ethernet. Now It is MAN and WAN standard.
Shared access network technology
Link layer technology
Use CSMA/CD
Backoff Algorithm
Low Cost
Easy to implement
Easy to manage
History
Aloha
Developed by Bob Metcalfe and others at Xerox PARC in mid-1970s.
If receive Ack then communication success otherwise send again. It was designed for 3Mb/s.
Slotted Aloha
Delay of transmission of collided packet for a random time.
DIX Ethernet in 1980
DIX was developed by three organizations Digital, Intel, and xerox. In 1980 DIX Ethernet v.1 was introduced with the speed of 10Mb/s.
Project 802 of IEEE
In 1985 IEEE started a project 802. Named for the year and month ('80 Feb). Its goal was to set standards to establish communication between devices. It defines a family of protocols at Data link and physical layers. Ethernet10BaseT was introduced. Manchester encoding.
802.1--overview of project 802, including higher layers and internetworking
802.2-logical link control (LLC)
802.3- Ethernet - carrier sense multiple access with collision detect (CSMA/CD.
802.4-token bus
802.5-token Ring
802.6-metropolitan area network
802.7-broadband technology
802.8-optical fiber technology
802.9-voice/data integration on LANs
802.10-standard for interoperable LAN security
IEEE 802.3 Data Link Layer = LLC + MAC
In ethernet architecture, data link layer is divided into two parts
LLC (Logical link control)
Upper layer communication
Flow control
Link establishment and termination
Framing
Interconnectivity between data link layer of different LAN.
MAC(Media access control)
Error Checking
Media access control
Frame transmission and its recovery in case of failure.
Interaction with physical layer
IEEE 802.3 CSMA/CD
CSMA = First listen then speak.
CD= While speaking, listen also. If someone speaking, stop.
Backoff Algorithm
Ethernet Frame.
Minimum packet size is 64 bytes.
18 header bytes and 46 data bytes.
Preamble:
CRC:
Signaling method (base, broad).
Baseband.
Broadband.
Twisted pair
10-BaseT twisted pair standard
Coaxial cable
10Base2 Thin coaxial standard.
10Base5 Thick coaxial standard
Fiber Optic
10Base-FL
100Base-Sx
100Base-Lx

The original Ethernet IEEE 802.3 standard defined the minimum Ethernet frame size as 64 bytes and the maximum as 1518 bytes. (mention your video is 46 bytes minimum )

One thing more you are talking about ethernet frame size on layer 2 but you are showing packet size. Confused. 64 and 1518 byte is the size of frame or packet ?
