What does FCS stand for? |
FCS stands for Frame check sequence. |
|
|
What function does FCS perform? |
FCS performs the function of verifying that the data has arrived intact. |
|
|
How does the FCS verify that the data has been sent correctly? |
The FCS verifies that the data has been sent correctly by using a binary math called CRC or cyclic redundancy check. |
