Answer: Validity

Explanation:Validity is the type of claim that is made towards the measuring of reliability of any element. The differences appearing in the measurement of the elements displays the validly factor is not up to the mark which indirectly implies that reliability is not high. Validity is the situation in which all the parameters appearing in the element is perfect. If validity is perfect then only perfect reliability is achieved.

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

List the three control problems associated with competingprocesses and briefly define each.
hjlf

Answer and explanation :

the three control problems associated with competing process are

  • MUTUAL EXCLUSION : We know that some resources are shareable and some are not shareable. which means only one process can access the resource at a time this type of resources are called critical resources this code can be access at only one process at a time. the other process if required to access should not be allowed
  • DEADLOCK: this hold the process without complete for example suppose there are two resources R1 and R2 and two process P1 and P2 and P1 use R1 and P2 use R2 but after some time when P1 needs R2 but R2 is not available as it is used by P2 so the all process will be on hold
  • STARVATION : when priorities are given to the process as high priorities and low priorities. And high priorities process always competing  then low priorities process have to wait for very long time this is called starvation
