Maximum Transmission Unit
<networking> (MTU) The largest number of bytes of "payload"
data a frame can carry, not counting the frame's header
and trailer.
A frame is a single unit of transportation on the {data link
layer}. It consists of header data plus data which was passed
down from the network layer (e.g. an IP datagram) plus
sometimes trailer data.
An Ethernet (V2) frame has a MTU of 1500 bytes but the size of
the frame can be up to 1526 bytes (22 byte header, 4 byte CRC
trailer).

Maximum transmission unit
In computer networking, the maximum transmission unit (MTU) is the size of the largest protocol data unit (PDU) that can be communicated in a single network layer transaction. The MTU relates to, but is not identical to the maximum frame size that can be transported on the data link layer, e.

In telecommunications, transmission is the process of sending or propagating an analog or digital signal via a medium that is wired, wireless, or fiber-optic.

Maximum transmission unit
In computer networking, the maximum transmission unit (MTU) is the size of the largest protocol data unit (PDU) that can be communicated in a single network layer transaction. The MTU relates to, but is not identical to the maximum frame size that can be transported on the data link layer, e.g. Ethernet frame.
Larger MTU is associated with reduced overhead. Smaller MTU values can reduce network delay. In many cases, MTU is dependent on underlying network capabilities and must be adjusted manually or automatically so as to not exceed these capabilities. MTU parameters may appear in association with a communications interface or standard. Some systems may decide MTU at connect time, e.g. using Path MTU Discovery.
