By the Port Number.
How can a bridge know whether to forward frames? Answer: The bridge builds a list of MAC addresses on either side of the bridge. Therefore, it knows which packets should be forwarded to the other side and which should not. In the example of a packet that uses a MAC address not in its table it can err on the side of caution by forwarding the packet.
who knows, maybe call skittles
So that the Free Service knows who you are when you come back to use it (the service knows you) also it is used by the service provider to monitor use of the service and perhaps tailor advertising to you.
A CRC is used to check for integrity of some information, for example, a data packet. The CRC is calculated, according to some formula, from the remaining bytes in the packet, before sending the packet. The receiving end recalculates the CRC; if any of the bytes have become corrupted (say, through electrical noise during the transmission), the CRC will no longer match, and the receiver knows that the packet has been damaged.

Francis Hopkins is known to have presented the committee with a flag as an example, but no one really knows who designed the current flag.
The originating system knows whether or not a packet was received through acknowledgment (ACK) mechanisms used in communication protocols. When a packet is sent, the receiving system is expected to send back an acknowledgment to confirm receipt. If the originating system does not receive this acknowledgment within a specified time frame, it assumes that the packet was lost or not received and may retransmit it. This process is fundamental in protocols like TCP, which ensures reliable data transmission.
I'm sure Roberto Mitchel knows, or even try Eric.
No one really knows but i hope all you guys do good on your north America packet! (if ur working on that)
Hello , Does anybody knows how to reset the service message on E430 MB 199. Thanks Denis Hello , Does anybody knows how to reset the service message on E430 MB 199. Thanks Denis
If she knows and you haven't confessed to her I think you should since she knows and then expect her to dump your butt
if no one knows about a job then how should we know
