Questions With Verified Solutions
A frame ends with a special bit called the frame check sequence (FCS). What does the FCS do?
A. Cycles data across the network
B. Verifies that the MAC addresses are correct
C. Verifies that the data arrived correctly

D. Verifies that the IP address is correct☑️Correct Ans-Verifies that the data arrived correctly;
