Answer:

True

Explanation:

A single file can be used to record/ store all the information regarding a transaction because in a transaction there are less complexities. a  simple transaction involves an exchange/communication between a buyer and a seller which involves exchange in finances between the buyer and the seller.  

An employee can be involved in several activities like work activities and multiple transactions while a single inventory part record is different from an employee's record and  any other form of transaction. hence separate files have to be created for each of these activities.

To have an easy access to this information when needed a master file is created to store all the individual files.

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

Consider a physical transmission medium of capacity C bits/sec between two stations that have I bits of information sent/receive
levacccp [35]

Answer:

Check the explanation

Explanation:

when calculating the total time to send the I bits of information or The packet delivery time or latency which can be said to be the amount of time from when the first bit leaves the point of transmission until the last is received. When it comes to a physical link, it can be computed or determined as: Packet delivery time = Transmission time + Propagation delay.

Kindly check the attached image below to get the step by step explanation to the above question.
