In an Ethernet frame, the field used for synchronization is the preamble. The preamble consists of 7 bytes of alternating 1s and 0s, followed by a 1-byte Start Frame Delimiter (SFD). This sequence allows the receiving device to synchronize its clock to the incoming signal, ensuring proper interpretation of the subsequent data in the frame.
What else can I help you with?
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 is the function of the FCS field in an Ethernet frame explain how it is used how it is used to make a header?
In an Ethernet frame, FCS stands for "Frame Check Sequence". It is a four-octet field used to verify that the frame was received without loss or error. The method used for verification is known as a Cyclic Redundancy Check (CRC).
Which encapsulation must be used to enable Ethernet II frame type on your Ethernet?
Arpa encapsulation must be used to enable Ethernet II frame type on your Ethernet.
How large is the FCS field of an Ethernet II frame?
The Frame Check Sequence (FCS) field of an Ethernet II frame is 4 bytes (32 bits) in size. It is located at the end of the frame and is used for error checking to ensure data integrity during transmission. The FCS helps detect any corruption that may occur in the frame as it travels across the network.
What is preamble in Ethernet?
The preamble is a 64-bit (8 byte) field that contains a synchronization pattern consisting of alternating ones and zeros and ending with two consecutive ones. After synchronization is established, the preamble is used to locate the first bit of the packet. The preamble is generated by the LAN interface card.(http://docs.hp.com/en/98194-90053/ch02s03.html)
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.
How is synchronization achieved in gsm?
A BSS has to generate the frame structure, which starts and ends with a tail field, and which has a training sequence in the mid. This fields can be used for synchronization. Each mobile device is doing its own synchronization due to this field, which is important because of time multiplexing to avoid overlapping data transmission, but BSS also has an important task to do in the synchronization: to make guard times small, it measures the distance to each end of device and calculates timing advances.
What addresses is used as a destination address for an Ethernet broadcast frame?
255.255.255.255
Can you change the frame type of an Network Interface card in an Ethernet network be used in a token ring network?
no. The differences between ethernet and token ring are greater then the frame type. Ethernet uses CDMA and token ring uses.....well a token. Token ring adapters have an on-board processor for source route bridging which uses a RIF field and ethernet has nothing of the sort. There are many more examples, but the simple answer is it will not work. fm
What type of address is used in an Ethernet frame header?
MAC addresses only
3 Which type of address is used in an Ethernet frame header?
logical addresses only
6 Which type of address is used in an Ethernet frame header?
Mac address only!
