What is an ethernet frame characterized by?

An Ethernet frame is characterized by a structured collection of information, which is essential for the proper transmission and reception of data over a network. Each Ethernet frame is composed of several key parts: a header, which contains source and destination MAC addresses; a payload, which carries the actual data being transmitted; and a trailer, which typically includes error-checking information.

The header ensures that the data is directed to the correct recipient, while the trailer helps verify the integrity of the data received, making it a well-defined and organized package of information rather than a random assortment of bytes. This structure is crucial for ensuring reliable communication within a network, particularly in identifying where the data should go and confirming that it has arrived without errors.

Furthermore, the other options do not accurately characterize an Ethernet frame. For instance, a random set of bytes lacks the organized format needed for effective communication. A single binary digit does not represent an entire frame and is instead the most basic unit of data. A temporary data store suggests a variable holding area, which does not align with the defined structure and purpose of Ethernet frames in data transmission.
