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.
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)
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
What type of address is used in an Ethernet frame header?
MAC addresses only
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
How is synchronization achieved in gsm who is responsible for synchronization and why it is so important?
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. These fields can be used for synchronization. Each mobile device is doing its own synchronization due to these fields - which is important because of the time multiplexing to avoid overlapping data transmissions. But also the BSS has an important task in the synchronization: to make the guard times small, it measures the distance to each end device and calculates timing advances.
Which protocol is used to discover the destination address needed to be added to an ethernet frame?
ARP
6 Which type of address is used in an Ethernet frame header?
Mac address only!
3 Which type of address is used in an Ethernet frame header?
logical addresses only
