Answer:
B. Create a lookup relationship to indicate that a person has an employer
Explanation:
Programmers are professional who build computer softwares.
Creating a lookup relationship to indicate that a person has an employer is the data model used to track the data of a developer creating an enhancement to an application that will allow people to be related to their employer. This data model allows for 25people per object.
C.) New discoveries make the current model inaccurate. Since
science is all about observation and experimentation, it is logical that
whenever new findings are gathered, scientific models must be modified to adapt
to the information. As new ideas and concepts are uncovered, models should be
updated to make them correct.
Explanation:
A.)
we have two machines M1 and M2
cpi stands for clocks per instruction.
to get cpi for machine 1:
= we multiply frequencies with their corresponding M1 cycles and add everything up
50/100 x 1 = 0.5
20/100 x 2 = 0.4
30/100 x 3 = 0.9
CPI for M1 = 0.5 + 0.4 + 0.9 = 1.8
We find CPI for machine 2
we use the same formula we used for 1 above
50/100 x 2 = 1
20/100 x 3 = 0.6
30/100 x 4 = 1.2
CPI for m2 = 1 + 0.6 + 1.2 = 2.8
B.)
CPU execution time for m1 and m2
this is calculated by using the formula;
I * CPI/clock cycle time
execution time for A:
= I * 1.8/60X10⁶
= I x 30 nsec
execution time b:
I x 2.8/80x10⁶
= I x 35 nsec

Answer:
Option (d) is correct
Explanation:
Previously saved capture files can be read using Wireshark. For this, select the File then open the menu. Then Wireshark will pop up the “File Open” dialog box.
Wireshark capture files, like the DemoCapturepcap file found in this lab, have a .pcapng extension, which stands for packet capture, next generation.
