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.
How does Wi-Fi differ from shared Ethernet in terms of topology media access control and error control?
The logical and physical topologies of Wi-Fi are the same as those of shared Ethernet. Detecting collisions is more difficult in radio transmission than in transmission over wired networks, so Wi-Fi attempts to avoid collision to a greater extent than the traditional Ethernet.

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
What Ethernet(II) frame field is used for error detection?
The Ethernet (II) frame uses the Frame Check Sequence (FCS) field for error detection. This field is a 4-byte cyclic redundancy check (CRC) value that is calculated based on the frame's contents before transmission. When the frame is received, the receiving device calculates the CRC again and compares it to the FCS value; if they do not match, an error is detected, indicating that the frame may have been corrupted during transmission.
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 Ethernet controller?
An Ethernet controller is a hardware component that manages the communication between a computer or device and a network over Ethernet. It handles tasks such as framing data for transmission, error detection, and flow control. Ethernet controllers can be integrated into the motherboard or exist as standalone network interface cards (NICs). They are essential for enabling wired network connectivity in both personal and enterprise environments.
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.
Aspects of Ethernet have remained relatively unchanged over the years?
Ethernet has maintained key characteristics such as its frame structure, which includes a preamble, destination and source MAC addresses, and a frame check sequence for error detection. The use of a shared communication medium and the concept of collision detection (in earlier versions) have also persisted. Additionally, Ethernet's adaptability to various physical media and speeds, from 10 Mbps to 100 Gbps and beyond, has allowed it to remain relevant while retaining its foundational principles. These enduring aspects contribute to Ethernet's robustness and widespread adoption in networking.
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
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.
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 . ;)
