What is an example of a composite key in a database table?
InvoiceID
CustomerID
ProductID
OrderID + ProductID
Answer:
b
Explanation:
OrderID + ProductID is an example of a composite key in a database table. The correct option is 4.
What is composite key?A composite key is a key in a database table that consists of two or more columns that uniquely identify each row.
In a database table, a composite key is the combination of OrderID and ProductID in a table that tracks sales transactions.
Because a single order can contain multiple products and multiple orders can contain the same product, neither column can uniquely identify a row by itself.
However, by combining the two columns, each row can be uniquely identified, ensuring that the data is accurate and complete.
Similarly, a combination of CustomerID and ProductID might be used in a sales system to track the products purchased by each customer.
Thus, the correct option is 4.

Which element should be used only when the content simply references the element
a. nav

c. hgroup
d. article
The element that should be used only when the content simply references the element is figure. The correct option is B.
What is element of referencing?The four components of the author, date, source, and title are all included in reference list entries.
There are four referencing conventions that are frequently used. They go by the names of the Modern Languages Association (MLA), American Psychological Association (APA), Harvard, and Modern Humanities Research Association (MHRA) systems.
In computer programming, a reference is a value that allows a program to access a particular piece of data indirectly, such as the value of a variable or a record, in the computer's memory or in another storage location.
As a result, accessing the data is referred to as dereferencing the reference, and the data is referred to as the reference's referent.
Thus, the correct option is B.

Assume the existence of a Window class with integer data members width and height. Overload the << operator for the Window class-- i.e., write a nonmember ostream-returning function that accepts a reference to an ostream object and a constant reference to a Window object and sends the following to the ostream: 'a (width x height) window' (without the quotes and with width and height replaced by the actual width and height of the window. Thus for example, if the window had width=80 and height=20, << would send 'a (80 x 20) window' to the ostream object.) Don't forget to have the function return the proper value as well. Assume the operator has been declared a friend in the Window class.
Answer:
Following are the code to the given question:
#include <iostream>//header file
using namespace std;
class Window //defining a class Window
{
private:
int width, height;//defining integer variable
public:
friend ostream& operator << (ostream& stm, Window& width)//defining a friend function that takes two parameters
{
return stm<<"a ("<<width.width<<" x "<<width.height<<") window"; //use return keyword that return its values
}
Window(int width, int height): width(width), height(height)//defining parameterized constructor that inherit width and height in its parameters
{}
};
int main() //Main method
{
Window w(80,90);//calling class constructor
cout<<w;//print object value
return 0;
}
Output:
a (80 x 90) window
Explanation:
In the above code, a class "Window" is defined that uses a friend function "ostream& operator" is declared that uses the "ostrea&" as a data type to hold two-variable "stm and w" in its parameter, and declared the parameterized constructor to hold value by inheriting width and height in its parameters.
Inside the main method, a class object is created that calls the constructor and uses the print method to print object value.

How does a filmmaker decide which events to include in a documentary?
Answer:
A documentary is a film based on facts in which the maker tries to portray an aspect of reality, such as politics, science, society or history, nature or the personal perception of the documentary maker.
Documentaries are informative in nature. Sometimes documentaries attempt to provide an objective picture of a subject. There is a lot of debate about what is objective, because the documentary maker chooses his images from reality, which is in itself a subjective act. In a creative author's documentary, the emphasis is on the subjective vision of the filmmaker.
Therefore, the documentary maker will select the events to include in the documentary according to the approach he or she wants to give to it, be it objective or subjective.

Difference between Hollerith and Burroughs machine
Explanation:
The tabulating machine was an electromechanical machine designed to assist in summarizing information stored on punched cards. Invented by Herman Hollerith, the machine was developed to help process data for the 1890 U.S. Census. Later models were widely used for business applications such as accounting and inventory control. It spawned a class of machines, known as unit record equipment, and the data processing industry.
Herman Hollerith (February 29, 1860 – November 17, 1929) was an American businessman, inventor, and statistician who developed an electromechanical tabulating machine for punched cards to assist in summarizing information and, later, in accounting. His invention of the punched card tabulating machine, patented in 1884, marks the beginning of the era of mechanized binary code and semiautomatic data processing systems, and his concept dominated that landscape for nearly a century.
Hollerith founded a company that was amalgamated in 1911 with several other companies to form the Computing-Tabulating-Recording Company. In 1924, the company was renamed "International Business Machines" (IBM) and became one of the largest and most successful companies of the 20th century. Hollerith is regarded as one of the seminal figures in the development of data processing.

nadine is the systems administrator for a network with a single subnet. The subnet uses 192.168.1.0 with a mask of 255.255.255.0. The network has 10 servers running Windows Server. Srv1 currently provides both DHCP and DNS services. Nadine wants to increase the fault tolerance for her DHCP servers. She installs a new server, Srv11, and configures it for DHCP. She configures a scope on Srv11 to match the scope on Srv1 and then excludes half of the addresses in the scope on Srv1 and the other half of the addresses on the Srv11. Nadine decides to test her solution and shuts down Srv1. As a test, she forces a workstation to release its IP address and request a new one. She finds that the workstation has the IP address 169.254.0.15 with a mask of 255.255.0.0. What should Nadine do to fix the problem?
Answer:
Authorize Srv11
Explanation:
In order to fix this problem, Nadine should Authorize Srv11. The problem is most likely being caused due to failure of authorization of the server. This would prevent this server from being on the same scope as Srv1 and therefore, it is why the IPaddress being given is different. DHCP is an automatic protocol and would not be able to provide an IP address in the same scope if the server is not Authorized to do so.

What is code?Computer code, or a set of instructions or a system of rules defined in a specific programming language, is a term used in computer programming (i.e., the source code). It is also the name given to the source code after a compiler has prepared it for computer execution.
Code, often known as source code, refers to text that a computer programmer has created in a programming language. Programming languages like C, C#, C++, Java, Perl, and PHP are examples.
Another less formal term for text produced in markup or style languages, such as HTML and CSS, is code (Cascading Style Sheets)
