king one of three actions: (1) Toss the frame/packet; (2) asking to resend he frame/packet that was in error; (3) correct the error without retransmission. Discuss the requirement and advantages/disadvantages for each of these scenarios. What is the single greatest advantage of having a checksum only for the IP header? Why is cyclic redundancy checksum (CRC) implemented for Ethernet and for wireless frames as an error control technique? Please use your own words to answer these questions, do not copy answers from the internet. Write about 1-2 pages. Thank you.
