Self_doubt
How computation actually occurs in these type of questions? For ex: If I declare a=10,b=20 and pass them f(a-b,a*2,b-a); Where f has signature like f(int *p,int *q,int *r).How actually things works out if i manipulate are there any temprary variables involved?

Ethernet
Consider two nodes A and B on the same Ethernet, and suppose the propagation delay b/w the two nodes is 225-bit times. Suppose at the time both nodes A and B begin to transmit a frame.Both nodes transmit a 50-bit jam signal after detecting collision. For 10^7 bit/set find the time at which both nodes A and B sense idle channel?
