Question:
In the _____ approach to integration through linking data collection and analysis methods, the two databases are brought together for analysis
Answer:
Mixed Methods Approach: connecting, building, merging, embedding
Explanation:
The mixed methods approach in research occurs when the researcher combines collection and analysis of data in one study. In other words, the researcher collects both qualitative and quantitative data(from surveys for example) and integrates and analyzes all in one study. The connecting, building, embedding and merging are methods used in the database to achieve mixed methods approach. Connecting links databases, building notes different databases in data collection, merging brings them all together for analysis, and embedding combines data collection and analysis at different points.
What are the advantages of using a database management system (DBMS) over using file-based data storage?
Answer:
Advantage of DBMS over file system
No redundant data: Redundancy removed by data normalization. No data duplication saves storage and improves access time.
Data Consistency and Integrity: As we discussed earlier the root cause of data inconsistency is data redundancy, since data normalization takes care of the data redundancy, data inconsistency also been taken care of as part of it
Data Security: It is easier to apply access constraints in database systems so that only authorized user is able to access the data. Each user has a different set of access thus data is secured from the issues such as identity theft, data leaks and misuse of data.
Privacy: Limited access means privacy of data.
Easy access to data – Database systems manages data in such a way so that the data is easily accessible with fast response times.
Easy recovery: Since database systems keeps the backup of data, it is easier to do a full recovery of data in case of a failure.
Flexible: Database systems are more flexible than file processing systems

Modify the solution to PP 11.1 such that it catches and handles the exception if it is thrown. Handle the exception by printing an appropriate message, and then continue processing more strings.
Answer:
Explanation:
The following code is written in Java. After finding the PP 11.1 file online I added the try/catch to the code as requested by the question. The program takes the input from the user, checks it's length, and if it contains more than 20 characters it throws the exception. This exception states that "the string has more than 20 characters" and then continues processing more strings until the user enters "DONE". The program has been tested and the output can be seen in the attached image below. Due to technical difficulties I have added the code as a txt file below.

Your new trainee is interested in ACLs (access control lists). He asks you want they can be used for. What should you tell him? A. Protect hosts from viruses.B. Classify network traffic.C. Provide high network availability.D. IP route filtering.
Answer:
B. Classify network traffic.
D. IP route filtering.
Explanation:
An access control can be defined as a security technique use for determining whether an individual has the minimum requirements or credentials to access or view resources on a computer by ensuring that they are who they claim to be.
Simply stated, access control is the process of verifying the identity of an individual or electronic device. Authentication work based on the principle (framework) of matching an incoming request from a user or electronic device to a set of uniquely defined credentials.
Basically, authentication and authorization is used in access control, to ensure a user is truly who he or she claims to be, as well as confirm that an electronic device is valid through the process of verification
Hence, an access control list primarily is composed of a set of permissions and operations associated with a network or file.
In Computer networking, access control lists (ACLs) can be used to perform the following tasks;
I. Classify network traffic: it can be used to classify the different networks on a router and define whether packets are rejected or accepted.
II. Internet protocol (IP) route filtering: any internet protocol (IP) address that's is not on the accept list would be refused permission into accessing a network. Thus, ACLs can either deny or accept IP addresses depending on the routing table configured on the router.

If we were ever to use this pizza ordering program again, we would want to use mainline logic to control its execution. The way it is written, it will automatically execute as soon as it is imported.
Re-write this program, enclosing the top level code into the main function. Then execute the main function. Enter appropriate input so the output matches that under Desired Output.
# Define Function
def pizza(meat="cheese", veggies="onions"):
print("You would like a", meat, "pizza with", veggies)
# Get the User Input
my_meat = input("What meat would you like? ")
my_veggies = input("What veggie would you like? ")
# Call the Function
pizza(meat=my_meat, veggies=my_veggies)
desired output:
What meat would you like? cheese
What veggie would you like? onions
You would like a cheese pizza with onions
2) We want to generate 5 random numbers, but we need the random module to do so. Import the random module, so the code executes.

The process of providing only the essentials and hiding the details is known as _____. a. algorithm b. data structure c. abstraction d. optimization
The process of providing only the essentials and hiding the details is known as abstraction.
What is abstraction?Abstraction in its main sense is a conceptual process wherein general rules and concepts are derived from the usage and classification of specific examples, literal ("real" or "concrete") signifiers, first principles, or other methods.
"An abstraction" is the outcome of this process—a concept that acts as a common noun for all subordinate concepts and connects any related concepts as a group, field, or category.
Conceptual abstractions may be formed by filtering the information content of a concept or an observable phenomenon, selecting only those aspects which are relevant for a particular purpose. For example, abstracting a leather soccer ball to the more general idea of a ball selects only the information on general ball attributes and behavior.
Therefore, The process of providing only the essentials and hiding the details is known as abstraction.

Ramjac Company wants to set up k independent file servers, each capable of running the company's intranet. Each server has average "uptime" of 98 percent. What must k be to achieve 99.999 percent probability that the intranet will be "up"?
Answer:
k = 3
Explanation:
K independent file servers
Average "uptime" of each server = 98%
To achieve 99.99% probability by the intranet
given that each server has an uptime = 98%
For the intranet to achieve 99.99% probability we have to choose more than 2 servers ( i.e. 3 servers ) incase any of the server goes down.
As each server posses an uptime of 98% it is almost impossible for all 3 servers to go down at the same time hence value of K = 3
It should be noted that the value of k to achieve 99.99 percent probability will be 3.
How to solve the probabilityFrom the information given, k is simply the independent file servers.
Also, the average uptime of each server is given as 98%. For the intranet to achieve 99.99% probability, it should be noted that more than 2 servers will be chosen.
In this case, it'll be impossible for the three servers to go down.

Presentation of the data abstracted from the database must take one of two forms: graphs and tabular forms. True False
Answer:
False.
Explanation:
There is also a third way of presenting data. Data can be presented in textual form, using paragraph structures. The other two are using graphs and tabular forms. Presenting data in a graph or pie chart gives a pictorial representation of the data, making the numbers easier to visualize and understand. Using tables also makes data presentation to be easily communicated. Text remains the method for explaining findings, outlining trends, and providing context, a table represents both quantitative and qualitative information, while a graph displays data for comparison.
