What Are The Two Sizes (Minimum And Maximum) Of An Ethernet Frame? (Choose Two.)

What are the two sizes (minimum and maximum) of an Ethernet frame? (Choose two.)

• 56 bytes.
• 1324 bytes.
• 1518 bytes.
• 64 bytes.
• 128 bytes.

Answer: The lowest frame for the Ethernet is 64 bytes while the maximum frame for the Ethernet is 1518 bytes. For the recognition of the runt and jumbo frames, the technician has to know about the maximum and the minimum frames.

Ethernet frames

With Ethernet, the data are shared in the form of data packets. The packets have many items in them such as the ethernet frames. The Ethernet frames are the protocol of the data link layer and use the Ethernet physical transport layer transport mechanism. In Ethernet data transmission methods, the responsibility of Ethernet frames is to ensure proper throttling and successful data packets.

The Ethernet frames are present at the data link layer of the OSI model and ensure the successful transmission of the data and the bitstream separation. The size of the ethernet is defined by the standard of ethernet 802.3 which is from 64 bytes to 1518 bytes. The least size is 64 bytes and the maximum size is 1518 bytes.

The frame of ethernet is discovered a long time ago and the first version is based on the 16-bit field which does not have its own defined types whereas modern Ethernet frames are used in Ethernet II.

Elements of the ethernet frames

The frames are categorized into several data sets. Records are maintained in which binary code is included which have the essential information such as address information, control, payload data, etc. Moreover, the Ethernet frames have 3 parts: Ethernet header which includes: preamble, SFD, Destination, source, and types, encapsulate data contains: Data and pad, and the Ethernet trailers.

Let’s see the further explanation of the ethernet frames elements in the following section:

Permeable: Its work is to provide information about the beginnings of the frame and it enables synchronization to the receiver.

Start Frame Delimiter (SFD): It tells theta the destinated MAC address filed begins with the next byte. The length of the SFD is 1 byte.

Destinated MAC: The destination device MAC address is saved in the MAC address. The field length is 6 bytes.

Source MAC: The MAC address for the source is contained in the Source MAC. The size of the field is 6 bytes. It can identify the source device as well.

Type field: the length of the type field is 2 bytes .in the IPV4 and IPV5 the protocol types are defined by it.

Data and pad: the least size of the field is 46 bytes. And the highest is 1500 bytes. The payload data is present in Data and pad. The data with less or high than the size limit in one data packet and cannot be packed by the network layer.

Frame Check Sequence: the length of the field is 4 bytes. The value with a length of 4 bytes is present in this field which ensures whether the frame is complete or not. The 32-bit cyclic redundancy check is present in it which allows the detection of the corrupted data.
