- - - - The first three octets(24 bits) of a MAC ADDRESS are known as Organizationally Unique Identifier
        
        Assigned to the individual hardware manufacturers by the IEEE
    - - OCTET
        
        8 BITS = 1BYTE
- - - - Find the length of the divisor L
        
        Append L-1 bits to the original message
        
        Perform binary division operation
        
        Remainder of the division = CRC
        
        :<3: CRC must be of L-1 bits
        :star: CRC is appended at the end of the data
    - - The receiver simply applies division in the data by the divisor(common to both sender and the receiver) if he gets
        all ZEROS -> :check: Accepted else :green_cross: Rejected
  - - - Single bit error Detection
        
        Can detect burst error only if the number of errors is odd.
