He could create foreign keys, which are basically columns in a table with values that identify a record from another table.

However, even without foreign keys you can construct queries that link data from multiple tables together.

Answer:

<em><u>The answer is</u></em>: <u>Importing, although you can also do it by copying and pasting, or creating a subreport.</u>

Explanation:

<u>If, for example, Lance</u>, you want to see customer data, but you also want to see information about customer orders at the same time. A subreport is a useful tool in Access to perform this task because it allows you to display the order information in the report with the customer information, in a logical and readable way. Access provides several ways to create subreports quickly.

He can also Import database objects to the current Access database. Access provides several ways to copy an object such as a table or form from one database to another. The simplest is to copy and paste an object, but importing an object from another Access database to the current database offers more options.

<em><u>The answer is</u></em>: <u>Importing, although you can also do it by copying and pasting, or creating a subreport.</u>

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
