Explain cross talk and what is needed to reduce it? Effect of one wire on another is called as cross talk. One wire will be the sending antenna and the other wire will be the receiving antenna. We can use the shielded twisted pair cable or coaxial cable for transmission, which contains metal foil to reduce cross talk. What are the responsibilities of data link layer? Specific responsibilities of data link layer include the following.
