Explanation / Answer

Answer of question 1 is 3(x.25). because it was designed to optimized 64 kb/s transmission over poor-quality telephone land lines..

Answer of question 2 is 1(5). atm transfer data in fixed sizes these are said to be cells and the total cells is 53(53bytes). in which 5 bytes are used for header or addressing

anser of question 3 is 1(48). as in above question total cells is 55 bytes and in which 48 bytes are used for data in atm cell.

answer of question 4 is 3(atm). atm is used for error detection at a frame level and the Hamming code is used for error correction at the cell level. this is to improve error protection.

Answer of question 6 is 3(Segmentation and Reassembly).
