Final answer:
Ethernet frames consist of various fields such as the CRC field for error-checking, the source address field to identify the sender, the data (payload) field for storing transmitted data, and the type field to indicate the protocol of the payload data. There is no sequence number field in a standard Ethernet frame.
Step-by-step explanation:
The question relates to the various fields in an Ethernet frame and their functions. Here's a brief overview:
Cyclic redundancy check (CRC) field: This field is used for error-checking the data. It helps ensure data integrity by detecting errors that might have been introduced during transmission.
Source address field: This field contains the address of the sender of the frame. It's used to identify the network interface card from which the frame originated.
Data (payload) field: This is the main content of the frame, where the actual data being transmitted is stored.
Type field: This field indicates the protocol of the data in the payload, allowing the receiving system to understand how to process the received packet.
The question mistakenly mentions a Sequence number fie which does not exist in a standard Ethernet frame. Perhaps it refers to a different protocol or context.
Ethernet frames are a fundamental part of network communications, ensuring that data packets are correctly formatted for transmission over network media.
