Complete Question:
What will the following segment of code output?
Assume the user enters a grade of 90 from the keyboard.
cout << "Enter a test score: ";
cin >> test_score;
if (test_score < 60);
cout << "You failed the test!" << endl;
if (test_score > 60)
cout << "You passed the test!" << endl;
else
cout << "You need to study for the next test!";
Answer:
You failed the test!
You passed the test!
Explanation:
With the assumption that test_score has been declared as an int variable
The output of: You failed the test! You passed the test! May be unexpected since the test_score is greater than 90 so it looks like the code has a logical error somewhere.
This error is as a result of putting a semi colon at then end of the first if statement if (test_score < 60);
An if statement does not end a thought as such there should'nt be a semi colon ending it. Take the semi-colon out and the program will give the expected output of You passed the test! since test_score of 90 is greater than 60

Write a statement that declares a PrintWriter reference variable named output and initializes it to a reference to a newly created PrintWriter object associated with a file named "output.txt".
Answer:
PrintWriter variable = new PrintWriter("output.txt");
Explanation:
There are two ways of declaring a reference variable in programming.
One way is
Reference Variable-name = new Reference ("some texts here");
While the other is
Reference Variable-name;
Variable-name = new Reference ("some texts here");
Both ways are valid ways of reference variable declaration.
In the question above, the reference is PrintWriter, it points to output.txt and the question says "write a single statement";
Hence, we make use of
PrintWriter variable = new PrintWriter("output.txt");
A reference variable is declared to be of a specific type and that type can never be changed.

Which installation changes from the old information system to the new one incrementally, starting with one or a few functional components and then gradually extends the installation to cover the whole new system?
Answer:
Phased installation
Explanation:
The name of this strategy is phased installation. Phased installation (or phased implementation) occurs when an existing system is replaced by a new one. However, unlike most implementations, this takes place in stages. This has several advantages. First, it allows you to test the system. If there is a problem with it, it is easier to revert back to the old strategy. Moreover, if employees need to adopt this new system, it allows them to get used to it slowly while still being able to access the previous one.
Final answer:
Incremental implementation is a method that replaces an old information system with a new one in a gradual manner, beginning with a few components and then extending to the entire system, which is part of the incremental design process.
Explanation:
The installation method where the old information system is replaced by the new one incrementally, starting with one or a few functional components and then gradually extending the installation to encompass the entire new system, is known as incremental implementation. This approach allows for portions of the system to be updated and enhanced piece by piece, providing a controlled transition from old to new systems and minimizing disruptions. It's a part of the overall incremental design process, where design is done in pieces, and each piece can be modified or enhanced as needed to gradually improve the entire system. Throughout the project, as design efforts increase, the necessary infrastructure, including supply chains for components and manufacturing facilities, must be established to support the production and distribution of the newly designed product or system.

You have two LANs connected via a router. Network 1 has a DHCP server with a single Ethernet interface. Network 2 does not have a DHCP server. You want the hosts on Network 2 to be able to get IP addresses from the DHCP server on Network 1. What should you configure
Answer:
You can connect to the DHCP using manual addressing if there is only one interface for ethernet on Network 1
Explanation:
For a device to connect to the Internet, it requires an IP Address, Subnet Mask, Default Gateway and DNS.
So, to connect to the Internet for Network 2, you need to manually change the IP addressing but leave other settings the same.
Let's say Network 1 is connected to this network
IP Address: 192.168.1.2
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.1.1
DNS: 192.168.1.1
Then, Network 2 has to be manually configured to
IP Address: 192.168.1.3
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.1.1
DNS: 192.168.1.1
Every other thing remains the same except a little change to the IP Address
Answer:
Configure a DHCP relay agent on the network 2 router interface and configure the hosts in the network 2 to receive IP address dynamically.
Explanation:
DHCP is an application layer protocol which is used to assign IP addresses and other configuration parameters dynamically.
DHCP relay agents are devices configured to allow networks with no DHCP server access other networks with DHCP for it's services. Without this relay agent, the host can not access the DHCP server in other networks because the router interface is a broadcast and will not broadcast to other interfaces.
Hosts in the network can only send DHCP request broadcast messages if configured for dynamic IP addressing.

Explanation:
Advanced analytics refers to a set of techniques that are designed to model internal and external data to gain valuable insights and predict future trends. Unlike traditional data analysis, which may focus only on explaining past events, advanced analytics dives deeper into data, especially Big Data, to provide a predictive outlook on future events or trends. It employs sophisticated methods such as statistical algorithms, predictive models, machine learning techniques, and what is known as data mining.
Big Data is vast in volume and includes structured, semi-structured, and unstructured data from different sources. The analysis goes beyond simple data aggregation; it involves inspecting, cleaning, transforming, and modeling data to discover useful information. Advanced analytics uses quantitative methods extensively, which is evident in practices such as regression analyses and applying multi-variate statistical techniques to discern patterns within large datasets.
Moreover, tools like SPSS, Stata, R, and Python facilitate the analysis of Big Data. The impact of Big Data and advanced analytics extends across different fields, revolutionizing the way we understand and utilize data. Particularly in political science, these waves of advanced analytics and machine learning are profoundly influencing the analysis of extensive political data.
