Suppose we have a network in which 3 nodes share a common transmission media. The length of the frame sent by every node is fixed to 1. We also suppose that every node has the probability of 0.6 to generate a frame to be sent in any time period of length 1. Please answer the following questions.

a) When pure ALOHA is adopted, what is the probability that a node successfully transmits a frame?
b) When slotted ALOHA is adopted, what is the probability that a node successfully transmits a frame?

Suppose nodes A and B are each behind their own NAT firewall (9.7 Network Address Translation). A ──── NAT_A ──── Internet ──── NAT_B ──── B A and B attempt to connect to one another simultaneously, using TCP. A sends to the public IPv4 address of NAT_B, and vice-versa for B.

ABC common stock is expected to have have dividends in year 1 of $3/share, year 2 of $3/share,year 3 of $3.2/share, year 4 of $3.4/share, and in year 5 of $3.6/share. Then dividends will grow at a constant rate of 6%. If the discount rate is 15% , what should be the current share price? Hint: The growing perpetuity (Gordon growth model) should be put into year 5 along with the year 5 dividend before taking the present values. $31.16 $31.80...
