Computer network MSS and MTU
Are these definations of MSS and MTU correct?? MSS is maximum payload of TCP segment. TCP segment (MSS + TCP header) For IPpacket, it consists of (MSS + TCP header + IP header) And payload of IP packet means (TCPheader + ... fragmentation always done at router?? Can it be done by source?? I am really confused about these terms. Plz verify.

Pipelining and CPI
Consider a nonpipelined processor design which has a cycle time of 10ns and average CPI of 1.4. If each pipeline stage adds extra 20ps due to register setup delay. The pipeline stalls 20% of the time for 1 cycle and 5% of the time for 2 cycles (these occurrences are disjoint). What is the new CPI?
