Answer:
A. an instance of the same data is stored in two or more places in the database.
Explanation:
Giving that Update Anomalies usually occur when the designated user person in keeping records or record master stored a particular data in more than one in a database. This is what is called duplication of data and is termed an irregularity on the part of the record keeper.
Hence, the correct answer to the question is " A. an instance of the same data is stored in two or more places in the database."

Match the definitions of different business communication to the type of document
Answer:
Convey more factual data that helps facilitate decision making - REPORTS
Reports are made with factual data to show the condition of the subject so convey more factual data that helps in decision making.
Are one page long - MEMORANDUMS
Memorandums are used to convey new information and are usually brief which means they take one or two pages.
Are written in a block style, with the body text aligned along the left margin - BUSINESS LETTERS
Business letters are to be as formal as possible and this includes writing them block style and aligning the text to the left margin.
Allow attachments of files, such as images - EMAILS
As emails are softcopy and computer based, they allow for the attachment of other files such as images, documents, audio, etc.
Answer:
emails -> allow attachments of files, such as images
reports -> convey more factual data that helps facilitate decision making
memorandums -> are one page long
business letters -> are written in a block style, with the body text aligned along the left margin
Explanation:
Hopes this helps.

Explanation:
Consider the classes Food, Cheese, and Velveeta where Cheese is a subclass of Food and Velveeta is a subclass of Cheese. State which of the following lines of code are legal.
Cheese c =new Food( );
Velveeta v =new Food( );
Cheese c =new Velveeta( );
Food f =new Velveeta( );
Food f =new Cheese( );
Answer:
Cheese c =new Velveeta( );
Food f =new Velveeta( );
Food f =new Cheese( );
Explanation:
The super-class is the parent class from which features and attributes are inherited from while the subclass or the child class is the class inheriting from the super or parent class.
In Java, the object instance of a class is created with the syntax;
class_name instance_name = new class_name();
Food is the super or parent class of Cheese (which makes Cheese its subclass) and Cheese is the parent class of Velveeta. The extends keyword is used to denote inheritance.

True or False: The major advantage of Arrays over ArrayLists in Java is the fact that while ArrayLists are fixed in size, an Array can increase or decrease in size as needed.
Answer:
False
Explanation:
It's the other way round actually. Arraylists do not have fixed size and can increase or decrease in size as needed. On the other hand, Arrays are fixed from when they are declared; they have a particular size that number of elements cannot go beyond.
An arraylist in Java is a class that is part of a Java collection framework(java.util) that can have variable sizes and only store objects, not primitive data like strings or integers. An array is a data structure in Java and can store both primitive data and objects, while having a fixed size at declaration.

(Numerical Data Representation) How many bits per word are required to represent the following positive decimal integers: a.0 through 100b.0 through 255c.0 through 256d.0 through 10,000,000
Answer:
a. 7 bits
b. 8 bits
c. 9 bits
d. 24 bits
Explanation:
Required
Number of bits per word
The formula to get the number of bits per word is:
[tex]2^n = N[/tex]
Where
n = bits
N = numbers
Solving (a) 0 to 100
There are 101 digits between 0 and 100 (inclusive)
So:
[tex]N = 101[/tex]
Substitute 101 for N in [tex]2^n = N[/tex]
[tex]2^n = 101[/tex]
101 can not be expressed as an exponent of 2.
So, we substitute 101 for the closest number greater than 101 that can be expressed as an exponent of 2.
So:
[tex]2^n = 128[/tex]
Express 128 as an exponent of 2
[tex]2^n = 2^7[/tex]
Apply law of indices
[tex]n = 7[/tex]
Hence, 7 bits are required
Solving (b): 0 through 255
There are 256 digits between 0 and 255 (inclusive)
So:
[tex]N = 256[/tex]
Substitute 256 for N in [tex]2^n = N[/tex]
[tex]2^n = 256[/tex]
Express 256 as an exponent of 2
[tex]2^n = 2^8[/tex]
Apply law of indices
[tex]n = 8[/tex]
Hence, 8 bits are required
Solving (c): 0 through 256
There are 257 digits between 0 and 256 (inclusive)
So:
[tex]N = 257[/tex]
Substitute 257 for N in [tex]2^n = N[/tex]
[tex]2^n = 257[/tex]
257 can not be expressed as an exponent of 2.
So, we substitute 257 for the closest number greater than 101 that can be expressed as an exponent of 2.
So:
[tex]2^n = 512[/tex]
Express 512 as an exponent of 2
[tex]2^n = 2^9[/tex]
Apply law of indices
[tex]n = 9[/tex]
Hence, 9 bits are required
Solving (d): 0 through 10000000
There are 10000001 digits between 0 and 10000000 (inclusive)
So:
[tex]N = 10000000[/tex]
Substitute 10000000 for N in [tex]2^n = N[/tex]
[tex]2^n = 10000000[/tex]
10000000 can not be expressed as an exponent of 2.
So, we substitute 10000000 for the closest number greater than 101 that can be expressed as an exponent of 2.
So:
[tex]2^n = 16777216[/tex]
Express 16777216 as an exponent of 2
[tex]2^n = 2^{24[/tex]
Apply law of indices
[tex]n = 24[/tex]
Hence, 24 bits are required
g Write a program that allows a user to input any text in your program. Using the tools that we have discussed, your program should output how many unique words were in the input and then output how many words were unique.
Answer:
Explanation:
The following function/program is written in Java. It asks the user for a sentence as an input and then splits that sentence into an array of words. Then it creates an arrayList for all of the unique words, comparing each word in the sentence with all of those in the ArrayList. If a word is found in the ArrayList it cancels the loop and moves on the next word in the sentence. Finally, it counts all of the unique words in the ArrayList and prints that total to the screen.
public static void uniqueWords() {
Scanner in = new Scanner(System.in);
System.out.println("Enter a sentence:");
String sentence = in.nextLine();
String words[] = sentence.split(" ");
ArrayList<String> uniqueWords = new ArrayList<>();
for (int x = 0; x < words.length; x++) {
boolean exists = false;
for (int i = 0; i < uniqueWords.size(); i++) {
if (words[x].equals(uniqueWords.get(i))) {
exists = true;
break;
}
}
if (exists == false) {
uniqueWords.add(words[x]);
}
}
System.out.println(uniqueWords.size());
}

You are a network technician for a small network. Your ITAdmin workstation just stopped communicating with all other computers in the network. You need to diagnose and fix the problem. The following IP addresses are used in this lab:
Location Computer Name IP Address
Networking Closet CorpServer 172.25.10.10
Office 1 Office 1 172.25.10.60
Office 2 Office 2 172.25.10.61
Support Office Support 172.25.10.62
IT Administration ITAdmin 172.25.10.63
Executive Office Exec 172.25.10.64
Answer:
Ping the other workstations from the IT Admin workstation to confirm that connection has been lost, check the status of the network interface card in the workstation with command ifconfig in the terminal, then reset the connection using ifdown and ifup commands. If the problem is not resolved, check the cable connection.
Explanation:
Ping is an ICMP echo message sent by a network host to another to check for connectivity. If they are connected, the other workstation responds with an ICMP response message.
The ifconfig in Linux systems displays the network adapters and their individual IP configurations. If there is no connection even after the network is reset, then the cable connectors could be the problem.
