I'm trying to understand networking concepts and I came across 
ETH MTU size. I'm curious to know what ETH MTU size is and how it affects network performance.

    The MTU, or Maximum Transmission Unit, for Ethernet networks is typically set at 1,500 bytes.

    This figure represents the maximum amount of data that can be transmitted over the physical link in a single frame.

    It is important to note that the 1,500-byte limit does not include the Ethernet header.

    The Ethernet header itself can be either 18 or 20 bytes in length, depending on the specific configuration.

    Higher-level protocols, such as IP, must ensure that their data packets fit within the 1,500-byte MTU limit.
