Final answer:
The standard Ethernet frame can carry a maximum payload of 1500 bytes of data; this size limit is referred to as the Maximum Transmission Unit (MTU).
Step-by-step explanation:
According to the standard Ethernet protocols, each Ethernet frame is designed to carry a maximum payload of 1500 bytes of data, not including the frame header and trailer. This size limitation is known as the Maximum Transmission Unit (MTU), which is the largest physical packet size that can be communicated in a single network layer transaction. To transmit data packets larger than the MTU, a technique known as fragmentation is used, where the data is split into smaller frames that conform to the network's MTU limit.
