Answer:
Insertion query for first row :
INSERT into Invoice_Line_Items (invoice_sequence, account_number, line_item_amount, line_item_description) Values (1, 160, '$180.23', "Hard drive Exchange");
Insertion query for second row :
INSERT into Invoice_Line_Items (invoice_sequence, account_number, line_item_amount, line_item_description) Values (2, 527, '$254.35', "Server update");
Explanation:
* In SQL for insertion query, we use INSERT keyword which comes under DML (Data manipulation Language).
* Statement is given below -
INSERT into Table_name (column1, column2, ....column N) Values (value1, value2, .....value N);
* With the use of INSERT query we can insert value in multiple rows at a same time in a table which reduces our work load.

Java programing:
Add two more statements to main() to test inputs 3 and -1. Use print statements similar to the existing one (don't use assert)
import java.util.Scanner;
public class UnitTesting {
// Function returns origNum cubed
public static int cubeNum(int origNum) {
return origNum * origNum * origNum;
}
public static void main (String [] args) {
System.out.println("Testing started");
System.out.println("2, expecting 8, got: " + cubeNum(2));
/* Your solution goes here */
System.out.println("Testing completed");
return;
}
}
__________
Answer:
import java.util.Scanner;
public class UnitTesting {
// Function returns origNum cubed
public static int cubeNum(int origNum) {
return origNum * origNum * origNum;
}
public static void main (String [] args) {
System.out.println("Testing started");
System.out.println("2, expecting 8, got: " + cubeNum(2));
System.out.println("3, expecting 27, got: " + cubeNum(3));
System.out.println("-1, expecting -1, got: " + cubeNum(-1));
System.out.println("Testing completed");
return;
}
}
Explanation:

What is a function?Simply said, a function is a "chunk" of code that you may reuse repeatedly so instead of having to write it out several times. Software developers can divide an issue into smaller, more manageable parts, which can each carry out a specific task, using functions.
A function, according to a technical definition, is a relationship between an amount of parameters and a set of potential outputs, where every other input is connected to precisely one output.
All the functions are to be written in uppercase:

A small publishing company that you work for would like to develop a database that keeps track of the contracts that authors and publishers sign before starting a book. What fields do you anticipate needing for this database
Answer:
The database can include the fields related to the Author such as name and address, related to Publisher such as publisher's name and address, related to book such as title and ISBN of the book and related to contract such as payment schedule, contract start and end.
Explanation:
The following fields can be needed for this database:
Author First_NameAuthor's Last_NameAuthors_addressPublisher_namePublisher_addressBook_titleBook ISBNcontract date : this can be start_date (for starting of contract) and end_date ( when the contract ends) payment_made: for payment schedule.Suppose you have 9 coins and one of them is heavier than others. Other 8 coins weight equally. You are also given a balance. Develop and algorithm to determine the heavy coin using only two measurements with the help of the balance. Clearly write your algorithm in the form of a pseudocode using the similar notation that we have used in the class to represent sorting algorithms
Answer:
Following are the algorithm to this question:
Find_Heavier_Coins(Coin[9]):
i) Let Coin[] Array represent all Coins.
ii) Divide coin[] into 3 parallel bundles and each has three coins, example 0-2, 3-5, 6-8 indicate a1 a2 a3
iii) Randomly select any two bundles and place them in balance [say a1 and a2]
iv) If Weigh of a1 and a2 has same:
// checking that if a3 has heavier coin
Choose any two 6-8 coins and place them onto balance [say 6 and 8]
If those who weigh has the same weight:
Third coin is coin heavier [say 7]
else:
The coin [6 or 8] is the one which is heavier on the balance
else:
//The coin has the package which would be heavier on the balance [say a1]
Select any two coins on balance from of the heavier package [say 0 and 1]
If they weigh the same weight:
Third coin is coin heavier [say 2]
else:
The coin that is heavier on the balance is the [or 0]
Explanation:
In the above-given algorithm code, a method Find_Heavier_Coins is declared which passes a coin[] array variable in its parameters. In the next step, if conditional block is used that checks the values which can be described as follows:
In the first, if block is used that checks a1 and a2 values and uses another if block in this it will print a3 value, else it will print 6 to 8 value. In the another, if the block it will check third coins value and prints its value if it is not correct it will print first coin valueYou are working at the Acme company that has the following environment: 400 Windows Servers 2. 8000 Windows client devices (laptops running Windows os) 40 Linux servers Active Directory Domain Services to provide dns services to all the hosts, both Windows and Linux. Acme acquires a small research company, Uni-Tech that uses Unix servers for all of its applications. For host resolution they use BIND
a. Describe what BIND is and what the acronym stands for? BIND stands for Berkley Internet Name Domain. BIND allows you to pick one of your computers to act as the DNS server.
b. This acquisition happens very quickly and on day one the business needs people at Uni-Tech to connect to hosts at Acme using hosts names that can be resolved by Active Directory. Describe a method for integrating the two environments that does not require too many individual tasks that will take many hours. (10) Describe how you would test to make sure your integration is working correctly.
Answer: Provided in the explanation section
Explanation:
(a). BIND is a type of DNS server used on the internet, actually it is reported to be most widely used DNS server on the internet. Also BIND is the de-facto standard on Unix like operating systems and Linux. Thus it can be used to locate computers on a network using domain names instead of their IP addresses. BIND was originally programmed at the University of California, Berkeley in the 1980s, this was made possible by a grant from US based DARPA program.
Originally, BIND stood for Berkeley Internet name daemon, but nowadays it is called Berkeley Internet name domain.
(b). In some of the clients in windows and Windows servers we will install LDP. By the LDP.exe we can test tDNS, Active directory woking , even we can add or modify. LDP is used to test and verify the Active Directory objects. We will install in windows machine then open the software, then from the menu we will select connect and type the IP adress of the Active Directory then we will select or type the objects of Active directory. For Linux system we have to openldap and can search the AD.
From Linux or Unix we can use the nmap tool which can test the network connectivity between all the computers whether it is windows or Linux. By nmap we can test by ICMP protocol to verify the network connectivity. By nmap we can scan all the port which are required to open from client to the server. We can also use nslookup to test DNS server from the client. By nslookup we can check that client can connect the server.
In this assignment, you will develop a C++ program and a flowchart that calculates a cost to replace all tablets and desktop computers in a business. Customers paying cash get a ten percent discount applied to the total cost of the computers (desktop and tablets). Customers financing the purchase incur a fifteen percent finance charge based on the total cost of the computers (desktop and tablets). Tablets costs $320.00 each and desktops costs $800.00 each. The tax is 75% (.075).
Requirements:
⦁ Use the following variables of the appropriate type: name of company selling the computers, the cost per each type of computer, number of computers to be purchased, discount if paying cash, sales tax rate. Tablets =$320 each and desktop computers = $800.00 each. Sales Tax Rate = .075, Discount Percent = .10, and Finance Charge = .15.
⦁ Variable names must be descriptive.
⦁ Use additional variables to hold subtotals and totals.
⦁ For customers paying cash, the discount should be subtracted from the total computer cost.
⦁ For customers financing the purchase, the finance charge should be added to the total computer cost.
⦁ The body of your program must use variables only; there should not be any "hard coded" values in the output statements. An example of hardcoding is
***Cost of tablets = 4 * 320****.
⦁ Use cout to output the values of the variables to the console. Your cout statement MUST use the variables to display the values
⦁ Display the cost of the computers, tax and average cost per computer. The average cost will be the total cost divided by the number of computers purchased. Display the discount if the customer decides to pay cash or the finance charge if the customer finances the purchase.
⦁ Output must be labelled and easy to read as shown in the sample output below.
⦁ Program must be documented with the following:
⦁ // Name
⦁ // Date
⦁ // Program Name
⦁ // Description
⦁ Develop a flowchart
Hints:
Total cost of computers = cost per tablet * number of tablets purchased + cost per desktop * number of desktops purchased
Calculate the cost if paying cash or financing
Calculate the tax
Average cost per computer = Total computer cost divided by the number of computers purchased

The degree of a point in a triangulation is the number of edges incident to it. Give an example of a set of n points in the plane such that, no matter how the set is triangulated, there is always a point whose degree is n−1.
Answer:
squarepentagonExplanation:
The vertices of a square is one such set of points. Either diagonal will bring the degree of the points involved to 3 = 4-1.
The vertices of a regular pentagon is another such set of points. After joining the points in a convex hull, any interior connection will create a triangle and a quadrilateral. The diagonal of the quadrilateral will bring the degree of at least one of the points to 4 = 5-1.

Which of the following meanings of the plus sign, +, are built-in to the language (and/or standard libraries or classes that we have been using with the language)?
A. Numeric subtraction
B. Numeric addition
C. string concatenation
D. The logical "or" operation
Answer:
Numeric Addition
Explanation:
Literally, the + sign is an arithmetic operator used to perform addition operation between numeric datatypes (integer, float, decimal, double, long integer, etc...)
Its default built in function of the plus is sign is to add variables, constants and/or expressions.
The plus sign is used as follows;
a = 5;
b = 3;
c = a + b
-------------
a + b = 5 + 3 = 8
8 will be saved in variable c. This is only possible using the plus sign.
The plus sign also has other function such as string concatenation but this function is language dependent (i.e. some programming languages do not use + for string concatenation).
Conclusively, the built in function of the plus sign is for numeric addition

Transaction is an action or series of actions the execution of which should lead to a consistent database state from another consistent database state. Discuss which properties that transactions should have for their correct executions. Provide two examples to support your answer.
Explanation:
A transaction is a very small system unit that can contain many low-level tasks. A transaction in a database system should maintain, Atomicity, Consistency, Isolation, and Durability − these are commonly known as ACID properties − in order to ensure accuracy, completeness, and integrity of the data.
An example of a simple transaction is as below, Suppose a bank employee transfers Rs 500 from A's account to B's account.
A’s Account
Open_Account(A)
Old_Balance = A.balance
New_Balance = Old_Balance - 500
A.balance = New_Balance
Close_Account(A)
B’s Account
Open_Account(B)
Old_Balance = B.balance
New_Balance = Old_Balance + 500
B.balance = New_Balance
Close_Account(B)
A(n) ________ is a server-based operating system oriented to computer networking and may include directory services, network management, network monitoring, network policies, user group management, network security, and other network-related functions.
Answer:
Network Operating System (NOS)
Explanation:
A network operating system (NOS) is an operating system that makes different computer devices connect to a common network in order to communicate and share resources with each other using a server. A network operating system can be used by printers, computers, file sever among others, and they are connected together using a local area network. This local area network which they are connected to works as the server.
The NOS also acts as a network security because it could be used as an access control or even user authentication.
There are two types of NOS
1) Peer to peer network operating system.
2) Client/server network operating system
A network operating system (NOS) is a server-based operating system oriented to computer networking and may include directory services, network management, network monitoring, network policies, user group management, network security, and other network-related functions.
Array A is not a heap. Clearly explain why does above tree not a heap? b) Using build heap procedure discussed in the class, construct the heap data structure from the array A above. Represent your heap in the array A as well as using a binary tree. Clearly show all the steps c) Show how heap sort work in the heap you have constructed in part (b) above. Clearly show all the step in the heap sort
Answer:
Sorted Array A { } = { 1, 4, 23, 32, 34, 34, 67, 78, 89, 100 }
Explanation:
Binary tree is drawn given that the binary tree do not follow both minimum heap and maximum heap property, therefore, it is not a heap.
See attached picture.
Output values below an amount
Write a program that first gets a list of integers from input. The input begins with an integer indicating the number of integers that follow. Then, get the last value from the input, and output all integers less than or equal to that value.
Ex: If the input is 5 50 60 140 200 75 100, the output is:
For coding simplicity, follow every output value by a space, including the last one.
Such functionality is common on sites like Amazon, where a user can filter results.

Explanation:
You are a network technician for a small corporate network that supports 1000 Mbps (Gigabit) Ethernet. The manager in the Executive Office says that his network connection has gone down frequently over the past few days. He replaced his Ethernet cable, but the connection problem has continued. Now his network connection is either down or very slow at all times. He wants you to install a new 1000 Mbps Ethernet network card in his workstation to see if that solves the problem.
If the new card does not resolve the issue, you will need to perform troubleshooting tasks to find the cause of the issue and confirm that the problem is fixed after you implement a solution. Following are some troubleshooting tasks you can try:
• Use the Network and Sharing Center and the ipconfig command on the Exec workstation to check for a network connection or an IP address.
• Look at the adapter settings to see the status of the Ethernet connection.
• Use the ping command to see if the workstation can communicate with the server in the Networking Closet. (See the exhibit for the IP address.)
• View the network activity lights for all networking devices to check for dead connections. In this lab, your task is to complete the following:
1. Install a new Ethernet adapter in one of the open slots in the Exec workstation per the manager's request.
2. Make sure that the new adapter is connected to the wall outlet with a cable that supports Gigabit Ethernet.
3. Resolve any other issues you find using the known good spare components on the Shelf to fix the problem and restore the manager's internet connection.
After you replace the network adapter and resolve the issues you found while troubleshooting, use the Network and Sharing Center to confirm that the workstation is connected to the network and the internet

Answer:
The step by step explanation
Explanation:
Before doing anything, the first thing to do is to select the 100BaseTX network adapter and reconnect the Cat5e cable. The 100BaseTX network adapter supports Fast
Ethernet which is all that is required.
Now do the following steps:
Step one
In Office 2, switch to the motherboard view of the computer (turning off the workstation as necessary).
Step two
On the Shelf, expand the Network Adapters category.
Step three
Identify the network adapter that supports Fast Ethernet 100BaseTX. Drag the network adapter from the Shelf to a
free PCI slot on the computer.
Step four
To connect the computer to the network, switch to the back view of the computer.
Step five
Drag the Cat5 cable connector from the motherboard's NIC to the port of the 100BaseTX network adapter.
Step six
To verify the connection to the local network and the Internet, switch to the front view of the computer.
Step seven
Click the power button on the computer case.
Step eight
After the workstation's operating system is loaded, click the networking icon in the notification area and click
Open Network and Sharing Center. The diagram should indicate an active connection to the network and the
Internet.
For one to be able to confirm the speed of the connection, it can be done by clicking the Local Area Connection link in the Network and
Sharing Center.
