Chip ethernet serial

Although bits and bytes might be sent over the wire serially, software neither knows nor cares. It just knows that some short time after one controller is fed a packet and told to send it, another controller will report that a packet is available, and allow software to read it.

A "serial port" is guaranteed to transmit bytes of data in the chronological sequence that software supplies them, and make them available to software in the chronological sequence they are received; it would be rather useless if it did not. All Ethernet and Internet systems guarantee that when a packet is sent from one node to another the arrangement of bytes made available to the recipient will match the arrangement of bytes supplied by the sender, but there is no common specification requiring that the chronological order in which data are transmitted have any relation to their arrangement within a packet.

Further, there only guarantees that can be made with regard to chronological sequencing of packets relative to each other are highly vague.

If packet X is delivered Sunday at am and packet Y is delivered the next day at pm, one can safely assume that Y was sent after X.

On the other hand, if X is delivered at and Y is delivered at , it's entirely possible that Y was sent first but X took longer to arrive. In fact it can work as a parallel communication medium, but we'd be getting into the murky waters of Internet routing here. It's not all that unusual for one packet to go one way and for another to go another way for some part of the transit between two computers on the Internet, so it can be parallel one part of the way.

There are even ways for accessing Internet that allow use of several network interfaces and that would allow for fully parallel communication. The question you asked is very tricky since on one side Internet operates on a completely different level from simple RS port. Even that Show 1 more comment. Overall it's a whole lot more complicated that a serial connection. Kevin Vermeer Silas Moeckel Silas Moeckel 71 1 1 bronze badge. You can certainly send one byte on an Ethernet line.

It's just as meaningless as a single byte on an rs line. Both need a higher layer protocol to make sense of the byte. Add a comment. From Wiki about the Internet protocol suite : The Internet protocol suite is the set of communications protocols used for the Internet and similar networks, and generally the most popular protocol stack for wide area networks.

From lowest to highest, the layers are: The link layer commonly Ethernet contains communication technologies for a local network. The internet layer IP connects local networks, thus establishing internetworking. The transport layer TCP handles host-to-host communication.
