What will be the order of the following fields in a frame relay 'frame format’?
A. Flag
B. FCS
C. Address
D. Information
Choose the correct answer from the options given below:

Correct option is A

Frame relay is a standardized wide area network technology that specifies the physical and logical link layers of digital telecommunications channels. The frame format in Frame Relay consists of several fields arranged in a specific order to ensure proper data transmission and error checking.
Flag (A): The flag field marks the beginning and the end of a frame. It is used to synchronize the frames.
Order: This field comes first in the frame.
Address (C): The address field contains the data link connection identifier (DLCI), which identifies the virtual connection.
Order: This field follows the flag field.
Information (D): The information field contains the actual data being transmitted.
Order: This field comes after the address field.
FCS (B): The Frame Check Sequence (FCS) field is used for error detection. It contains the CRC value for error checking.
Order: This field comes at the end of the frame.
