A large population of ALOHA users manages to generate 50 requests/sec, including both originals and retransmissions. Time is slo

krok68 [10]

Answer:

The answer is below

Explanation:

Given that:

Frame transmission time (X) = 40 ms

Requests = 50 requests/sec, Therefore the arrival rate for frame (G) = 50 request * 40 ms = 2 request

a) Probability that there is success on the first attempt = $e^{-G}G^k$ but k = 0, therefore Probability that there is success on the first attempt = $e^{-G}=e^{-2}=0.135$

b) probability of exactly k collisions and then a success = P(collisions in k attempts) × P(success in k+1 attempt)

P(collisions in k attempts) = [1-Probability that there is success on the first attempt]^k = $[1-e^{-G}]^k=[1-0.135]^k=0.865^k$

P(success in k+1 attempt) = $e^{-G}=e^{-2}=0.135$

Probability of exactly k collisions and then a success = $0.865^k0.135$

c) Expected number of transmission attempts needed = probability of success in k transmission = $e^{G}=e^{2}=7.389$

Select the two true statements about functions with parameters:

kondor19780726 [428]

Answer:

Option (B) and (C) is the correct option to the following question.

Explanation:

Because the function is the module of the program and we call that function again and again anywhere whenever we need that function in the program.

Function is used to carry out any operation which is used in the program many times and it creates the program short and simple.

<u>For example</u>: if we need to add or multiply two numbers many times in the program then, we create one or two functions for addition and subtraction or one program for both, when we need them we call them.

Packet loss is typically resolved by time-outs and retries. For applications where a duplicate operation doesn't matter this is acceptable.
