The minimum Ethernet frame size that will not be discarded by a network is 64 bytes. This includes the frame header and CRC (cyclic redundancy check) trailer. Any frame that is smaller than this will be considered as an error and will be discarded.

Ethernet
Basics of Ethernet
Ethernet is a family of computer networking technologies commonly used in local area networks (LAN), metropolitan area networks (MAN) and wide area networks (WAN). It was commercially introduced in 1980 and first standardized in 1983 as IEEE 802.3, and has since gone through multiple revisions. The name comes from the physical concept of ether.
Ethernet Covers both wired and wireless connections
IEEE 802.3 is the standard for wired Ethernet, which includes twisted pair cabling (UTP, STP), coaxial cable, and fiber optic cable. The standard covers speeds up to 10 Gbit/s and can be used in LANs, MANs, and WANs.
There are three common types of Ethernet: twisted pair Ethernet, fiber optic Ethernet, and wireless Ethernet:
-Twisted pair Ethernet: Also known as 10BASE-T or 100BASE-TX, this is the most common type of Ethernet today. It uses an 8P8C connector (also called an RJ45 connector) with four pairs of copper wires (twisted around each other to minimize interference). One pair is used for sending data and the other for receiving data. Twisted pair Ethernet can reach speeds up to 100 Mbit/s or 1 Gbit/s over short distances (up to 100 meters).
-Fiber optic Ethernet: Also known as 100BASE-FX or 1000BASE-X, this type of Ethernet uses fiber optic cables instead of copper wires. It can reach speeds up to 1 Gbit/s over long distances (up to 10 kilometers). Fiber optic cable is less susceptible to electromagnetic interference than copper wire, so it is often used in environments where there is a lot of electrical interference (such as factories).
-Wireless Ethernet: Also known as Wi-Fi or WLAN, this type of Ethernet uses radio waves instead of wires to connect devices. It can reach speeds up to 1 Gbit/s over short distances (up to 100 meters). Wireless Ethernet is often used in homes and small businesses where it would be difficult or expensive to run wires between devices.
Ethernet Frame Types
There are three types of Ethernet frame: Type I, Type II, and Type III.
The minimum Ethernet frame size is 64 bytes, which includes the 14-byte header and the 42-byte trailer (FCS). Any frame less than this will be discarded by the network.
Minimum Ethernet Frame Size
The minimum Ethernet frame size is 64 octets. If less than this amount of data is sent, it will be padded to reach this minimum. Any frames larger than the maximum permitted 1518 octets will be discarded. There are two types of padding used with Ethernet frames: inter-frame gap (IFG) and end-of-frame delimiter (EoF).
Inter-frame gap (IFG) is used to provide time for the receiver to process the received frame and prepare for the next one. The gap consists of 12 octets of all ones. This ensures that the transmitted signal does not have any false starts or runts.
End-of-frame delimiter (EoF) is used to mark the end of the frame. It consists of 4 octets of all zeros, followed by a 32-bit CRC value. The EoF helps the receiver to align the bits in the next frame correctly.
What is the Minimum Ethernet Frame Size That Will Not Be Discarded by?
There is a minimum Ethernet frame size that will not be discarded by. This is known as the minimum Ethernet frame size. The minimum Ethernet frame size is 64 bytes. This includes the preamble, start frame delimiter, destination address, source address, data, Cyclic Redundancy Check (CRC), and the Inter-Frame Gap (IFG).
Discarded Frames
Discarded frames are Ethernet frames that are considered to be invalid and are therefore dropped by the receiving device. There are several reasons why a frame might be considered invalid, but the most common reason is that the frame is too small.
The minimum Ethernet frame size is 64 bytes, which includes the 14-byte Ethernet header and the 46-byte minimum data payload. If an Ethernet frame is smaller than this, it will be discarded by the receiving device.
There are two main reasons why small frames might be sent on an Ethernet network. The first is that some devices incorrectly calculate the checksum for smaller frames, which causes them to be rejected by other devices on the network. The second reason is that devices may deliberately send smaller frames in order to save bandwidth. However, this can cause problems because smaller frames are more susceptible to corruption and may be dropped more often than larger ones.
Minimum Frame Size
The Ethernet frame size is the number of octets contained in the data field of an Ethernet frame. The minimum Ethernet frame size is 64 octets, but the actual frame size can be any multiple of these octets, up to the maximum value. The maximum value is 1,518 octets, which includes the 14-octet Ethernet header and 4-octet CRC.
Why Frames Are Discarded
Ethernet is a packet-based technology that encapsulates data in frames for efficient transmission over the network. Each frame has a specific format that includes a header and a payload. The header contains information about the frame, including the source and destination MAC addresses, which are used to deliver the frame to its intended destination. The payload is the actual data being sent.
If a frame is too small, it will be discarded by the network because it cannot contain all of the necessary information. The minimum Ethernet frame size that will not be discarded by the network is 64 bytes. This includes the header and payload. Anything smaller than this will not be able to properly communicate over the network and will be discarded.
How to Avoid Discarded Frames
Ethernet transmits data in units called frames. If a frame is smaller than the minimum allowed by the standard, it will likely be discarded by the receiving node. To avoid this, you need to make sure that the minimum Ethernet frame size is used.
Use a Larger Frame Size
It is important to remember that the use of a larger frame size does not guarantee that your Ethernet frames will not be dropped. If you are using a congested network, your frames may still be dropped. The only way to guarantee that your Ethernet frames will not be dropped is to use a network with no congestion.
Use a Smaller Frame Size
One way to avoid having your Ethernet frames discarded is to use a smaller frame size. If you are able to segment your data into smaller packets, you can reduce the likelihood of your frames being discarded.
Another way to reduce the likelihood of your frames being discarded is to use a more reliable Ethernet connection. If you are using a Wi-Fi connection, for example, there is a greater chance that your frames will be discarded than if you are using a wired connection.
Use a Fragmentation Technique
There are two main techniques that can be used in order to avoid having Ethernet frames discarded by a receiving system:
1) Use a fragmentation technique – this involves breaking up larger frames into smaller ones that can be more easily processed by the receiving system;
2) Use an error-correction technique – this involves adding extra information to the frame that can be used by the receiving system to correct any errors that may have occurred during transmission.
Conclusion
The minimum Ethernet frame size that will not be discarded by is 64 bytes.
