Each Ethernet frame contains a trailer with a cyclic redundancy check (CRC) of the frame contents. After reception of a frame, the receiving node creates a CRC from the bits in the frame to compare to the CRC value in the frame trailer. If these two CRC calculations match, the frame can be trusted as being received without error. The trusted frame will then be processed. A frame received with bad, nonmatching CRC's will be discarded.

What two key elements comprise error control?
Detection of errors and retransmission of frames that are received in error.
Advantage of error detection and correction?
To be able to detect or correct errors, we need to send some extra bits with our data. These redundant bits are added by the sender and removed by the receiver. Their presence allows the receiver to detect or correct corrupted bits

What is the purpose of the Frame Check Sequence field in a Data Link frame trailer?
The purpose of the FCS field is to transmit the extra checksum characters added to a frame in "xyz" protocol for error detection. The most popular algorithm I've used is the CRC (cyclic redundancy check) employed in things like ethernet or PPP on a routed network. Keep in mind that ethernet defines that the errored frame should be discarded, but ethernet takes no action to cause the frame to be retransmitted. Typically most tech's see it as unnecessary overhead and opt to rely on CSMA\CD or CSMA\CA if the route is not deemed to carry time sensitive data. Hope that clears things up a bit.
List and briefly explain the services provided by the network layer of the Internet on the scope of transport layer protocol?
hii frnds it provides framing error control, flow control and link management, error detection and correction
Used for error detection?
Used for error detection
Which field of an Ethernet frame is used for error detection?
c) Check frame sequence. The FCS (4 bytes in length) field is used to detect errors in a frame
Basic operation of collision detection in Ethernet?
The basic operation of collision detection in Ethernet is to allow any station to send a packet whenever it is ready. This transmission is known as unslotted ALOHA.
What is the difference between Error detection and error correction?
In error detection we detect the error.but in error correction we can detect as well as coreect the error both.in error detection we use parity multiplication system i.e even and odd parity.and in error correction we use hamming code as a example.
Which ethernet card can handle gigabit network traffic?
You would need the ethernet card can handle gigabit network traffic cable.
4 Give two reasons why network might use an error correcting code instead of error detection and retransmission?
1)Time taken to error correcting is less than doing detection and retransmission. Bandwidth use will be less. 2) In detection and retransmission if back messaging occurs the bandwidth will be more
How are synchros used in error detection?
Control systems are synchros which are used in error detection. They provide a voltage to be converted to torque through an amplifying method.
Why is collision detection more complex in wireless networks than in wired networks such as Ethernet?
because it is . ;)
I heard that the E76 error is a Ethernet problem but I dont have Ethernet what do you do?
You can try resetting your Xbox or just try connect your console via Ethernet cable? Maybe it just needs a required connection but it depends on what you were trying to do when the error came up.
What is an error handling error?
Error handling refers to the anticipation, detection, and resolution of programming, application, and communications errors.
What type of information is in an Ethernet frame trailer?
The information found in the Ethernet frame trailer would be the error checking code.
