ans of q1 is wrong ,
right asn is Option C: 20,000 bits

time =(10^-6*200*10^3 )/200
= 10^-3 sec
there fore no of bit =20Mbps*10^-3
=20,000 bit

IP is responsible for ____ communication while TCP is responsible for ____ communication.
Option A: host-to-host ; process-to-process
Option B: process-to-process; host-to-host
Option C: process-to-process; node-to-node
Option D: node-to-node; process-to-process
Your Answer: A
Correct Answer: B
IP at Network Layer layer uses IP of Source and destination i.e host level, TCP (Tranport Layer) uses Source Port and Destination ports i.e Application/process level. MAC has a Node level function as it changes at every hop. I think the answer A is the correct it..........
