Final answer:
Programmers use Integrated Development Environments (IDEs) to develop, modify, and test software. These environments include tools for version control, like GitHub, and practices such as unit testing to ensure software quality.
Explanation:
Applications that programmers use to create, modify, and test software are referred to as Integrated Development Environments (IDEs). An IDE is a powerful suite of software development tools in one single application. It enables programmers to write code, debug errors, and test their applications before deployment. Features like versioning allow developers to manage different stages of their software builds, and tools like GitHub facilitate collaboration and source code management among teams. Unit testing is a crucial process in an IDE that allows developers to validate each part of the code individually to ensure correct behavior.
Other types of applications, often referred to simply as apps, include software like word processors, media players, and accounting software, designed to perform specific tasks for end-users. However, it's the development apps like IDEs where software creation and modification occur.

a. Use the Euclidean algorithm to compute the GCDs of the following pairs of integers State how many iterations each one takes to compute, and the value of the potential s at each stage. Verify that indeed si+1≤2/3si. i. (77,143) ii. (90, 504) ii. (376, 475) iv. (987, 1597)b. Try to find pairs of inputs (x, y such that the number of iterations of Euclid(x, y) is "large", that is, as close as possible to the upper bound of loga3/2(x+y) that we derived in lecture. Can you come up with a hypothesis about what kinds of inputs yield the worst-case running time?
Answer:
Explanation:
(a). given GCD (77,143)
143 = 77.1 + 66
77 = 66.1 + 11
66 = 11.6 + 0
∴ the gcd (77,143) = 11
the number of iterations = 3
(ii). GCD(90,504)
504 = 90.5 + 54
90 = 54.1 + 36
54 = 36.1 + 18
36 = 18.2 + 0
∴ the gcd(90,504) = 18
the number of iterations = 4
(iii). GCD(376,475)
475 = 376.1 + 99
376 = 99.3 + 79
99 = 79.1 + 20
79 = 20.3 + 19
20 = 19.1 + 1
19 = 1.19 + 0
∴ the gcd(376,475) = 1
the number of iterations = 6
(iv). GCD(987,1597)
1597 = 987.1 + 610
987 = 610.1 + 377
610 = 377.1 +233
377 = 233.1 +144
233 = 144.1 + 89
144 = 89.1 + 55
89 = 55.1 + 34
55 = 34.1 + 21
34 = 21.1 + 13
21 = 13.1 = 8
13 = 8.1 9+ 5
8 = 5.1 + 3
5 = 3.1 + 2
3 = 2.1 + 1
2 = 1.2 + 0
∴ the gcd(987,1597) = 1
the number of iterations = 15
(b). the pairs of inputs for which the number of iterations is large is given thus;
1. gcd(8,5)
8 = 5.1 + 3
5 = 3.1 + 2
3 = 2.1 + 1
2 = 1.2 + 0
the number of iterations from this is 4
2. also gcd(8,13)
13 = 8.1 + 5
8 = 5.1 + 3
5 = 3.1 + 2
3 = 2.1 + 1
2 =1.2 + 0
the number of iteration from this is 5
→ from the examples given, the worst case scenario occurs when the inputs are conservative Fibonacci numbers.
cheers, i hope this helps.
When writing functions that accept multi-dimensional arrays as arguments, ________ must be explicitly stated in the parameter list.
Answer:
size of all dimensions but the first.
Explanation:
This is because of a certain thing known as addressing. Compiler, in order to access any data, needs to know its address in memory.
If we don't pass in the value for any dimension after the first, compiler can't calculate the address of given array location we may want to access inside a function.
E.g.
void Foo(int bar[][3]) {
bar[1][2];
}
In the above example, the compiler needs to know the no. of columns in "bar" array to figure out the address of bar[1][2] and access the data underneath.
Because, in order to go to 2nd row in the array, compiler needs to know how much memory allocation (columns) is in a row.

Write a Java method onlyDigits that takes a string as a parameter. The method should remove from the string all characters, which are not digits, and return a string that contains only digits.
Answer:
public static String onlyDigits(String in){
String digitsOnly = in.replaceAll("[^0-9]", "");
return digitsOnly;
}
A Complete program is wrtten in the explanation section
Explanation:
public class TestClass {
public static void main(String[] args) {
String a = "-jaskdh2367sd.27askjdfh23";
System.out.println(onlyDigits(a));
}
public static String onlyDigits(String in){
String digitsOnly = in.replaceAll("[^0-9]", "");
return digitsOnly;
}
}
The output: 23672723
The main logic here is using the Java replaceAll method which returns a string after replacing all the sequence of characters that match its argument, regex with an empty string
Create a step-by-step IT security policy for handling user accounts/rights for a student who is leaving prematurely (drops, is expelled, and so on).
You will need to consider specialized student scenarios, such as a student who works as an assistant to a faculty member or as a lab assistant in a computer lab and may have access to resources most students do not.
Answer:
Step 1
IT security policies for handling user accounts or rights for a student
IT security is simply protecting computer systems from being robbed or damaged in terms of
Misdirection for service they produce Software'sHardware andinformationStep 2:
Account/Right is one of the security policies IT provides.Policies that can be written for handling user accounts includes
User account must reside within the system authorized by IT teamUser account protection User account responsibility User account and their access must agree to condition of usage established by IT.Policies for students who are leaving prematurely:
Expiry and deletion of user account:
When a course is finished or when a particular student withdraws from the course then user account gets terminated or deleted automatically.Achieving this can be through changes in authorization or deleting the account itself if no privileges are on the account
Step 4
Responsibilities of user account
A working assistant for the faculties who is a student would be given extra privileges compared to a normal student.For these category of students while exiting from the university they should hand over the responsibility , user account and password to the authority as required.
The access to other servers within the intranet or other resources are terminated.
Step 5
Privilege user account:
When assistant who are students drop out of a course,they should temporarily handover their user account to the concerned office.Now when they rejoin the the faculty he or she has the ability to take up the responsibility for handling the user's account
Step 6
Protection of user account
Assistants who are students or normal students ,while leaving at any time or for any reason should not relate their login ID's and password.IT polices do not request for user ID's under any circumstance.Hence it is he job of the student to maintain secrecy of their login ID and their password.
Explanation:
The above answer is an outline of an IT policy in order gain an insight on it let first define the term IT policy
IT policy
An IT policy can be defined as a lay down rule or a course of action adopted by an IT organisation to guild their activities in order to arrive at a particular outcome.this policies are implemented as a procedure or a protocol.
Some of the function of an IT policy include
1 To make available an IT infrastructure that would help the user identify opportunities , improve performance and understand business environment.
2 To evolve and archive information as corporate resource and to offer infrastructure to ensure coherent access for user to complete, concise and timely information.
The above answer provides a student with the necessary information to be able to make use of the resource on the faculties network.and be guided on outcome of some situation and conditions
Final answer:
To manage the IT security for user accounts of departing students with special access, one should follow a strict protocol involving notification, access review, revocation of rights, audits, documentation, continuity planning, and regular policy updates.
Explanation:
Step-by-Step IT Security Policy for Handling User Accounts/Rights
When a student who has been granted special access to certain resources (such as a faculty assistant or a lab assistant) leaves a college or university prematurely, it is crucial to follow a structured approach to revoke their access and secure the institution's systems. Here is a detailed step-by-step IT security policy to handle such scenarios:
Audit: Perform further audits on systems and services that were accessible to the student to ensure no security breaches or data manipulations.
Continuity Planning: Assess the need for a replacement or redistribution of the student's previous responsibilities to ensure continuity.
Policy Review and Update: Regularly review and update the IT security policy to incorporate new challenges and technologies.
Ensuring that explicit rules like the ones contained within a Student Handbook are diligently enforced is vital for maintaining the integrity of the institution's IT infrastructure, particularly when dealing with cyberbullying, identity theft, and other emerging issues.

An advertising company wishes to plan an advertising campaign in three different media: television, radio, and magazines. The purpose of the advertising program is to reach as many potential customers as possible. The results of a market study are given:
Answer:
It all depends on the demand for the product and address the area of coverage.
Explanation:
First, of all, there should be demand for the product and which area segment will be covered and the advertising company has to do a proper system before starting advertisement through media television and radio and magazines.
Mostly advertisement companies prefer to advertise on television were watching or view of television is more compare to reading a magazine or listening to the radio.
Advertise company has to select the which media will be useful to promote the product of a company
Using your favorite imperative language, give an example of each of the following. (a) A lexical error, detected by the scanner (b) A syntax error, detected by the parser (c) A static semantic error, detected by semantic analysis (d) A dynamic semantic error, detected by code generated by the compiler
Explanation:
a. int foo+; (foo+ is an invalid identifier because + is not a valid char in identifiers)
b. foo int; (Syntax error is any error where the syntax is invalid - either due to misplacement of words, bad spelling, missing semicolons etc.)
c. Static semantic error are logical errors. for e.g passing float as index of an array - arr[1.5] should be a SSE.
d. I think exceptions like NullReferenceException might be an example of DME. Not completely sure but in covariant returns that raise an exception at compile time (in some languages) might also come in this category. Also, passing the wrong type of object in another object (like passing a Cat in a Person object at runtime might qualify for DME.) Simplest example would be trying to access an index that is out of bounds of the array.
What Linux services can pose a problem when attempting to reach remote host on a network?
Answer:
NFS configuration
Explanation:
The Linux server runs the Linus open source operating system that provides a stable, secure and more flexible environment to carry out more challenging jobs like network and system administration, database management and web hosting.
The NFS or Network file system configured on the Linux server only supports Linux servers communication. It mounts the storage of the server on the network for central access.
Answer:
NFS Configuration
Explanation:
The Network File System (NFS) is a way of mounting Linux discs/directories over a network. An NFS server can export one or more directories that can then be mounted on a remote Linux machine. Note, that if you need to mount a Linux filesystem on a Windows machine, you need to use Samba/CIFS instead.
The NFS enables a UNIX workstation to mount an exported share from the server into its own filesystem, thus giving the user and the client the appearance that the sub filesystem belongs to the client; it provides a seamless network mount point.
Which of the following is the binary translation of signed decimal -33 ?
a. 11011111
b. 10101011
c. 11001100
d. 11100011
A. 11011111
Explanation:To convert -33 to a signed binary number, a 2's complement representation of the number is used. Signed numbers are stored on the computer using 2's complement notation.
(i) First convert 33 to binary
2 | 33
2 | 16 r 1
2 | 8 r 0
2 | 4 r 0
2 | 2 r 0
2 | 1 r 0
2 | 0 r 1
Therefore writing the remainders from bottom to top, we have that
33 in binary is 100001
(ii) Since the options are all in 8 bits, convert the binary to its 8-bit representation by padding it with zeros(0s) at the left.
=> 100001 = 00100001
(iii) Now, convert to 2's complement by
(a) flipping all the bits in the binary number. i.e change all 1s to 0s and all 0s to 1s
=> 00100001 => 11011110
(b) and then adding 1 to the result as follows;
1 1 0 1 1 1 1 0
+ 1
1 1 0 1 1 1 1 1
Therefore, -33 to binary is 11011111
Hope this helps!
Final answer:
The binary translation of signed decimal -33 in two's complement representation is 11011111, which corresponds to option (a).
Explanation:
To find the binary translation of the signed decimal -33, we use the two's complement method which is a way of encoding negative numbers in binary. First, we find the binary representation of the positive number, then invert all the bits (change 0s to 1s and 1s to 0s), and finally, add 1 to that inverted number.
The binary representation of 33 is 00100001. Inverting the bits gives us 11011110. Adding 1 to that gives us 11011111, which is option (a).

design a 4-bit even up-counter using D flip flop by converting combinational circuit to sequential circuit. The counter will only consider even inputs and the sequence of inputs will be 0-2-4-6-8-10-0.
1. Draw the State diagram.
2. Generate State & Transition Table.
3. Generate simplified Boolean Expression.
4. Design the final Circuit diagram.
Answer:
Below is a possible implementation using D-flip-flops.
Explanation:
Creating a counter that only counts even numbers is easy, just add a dummy bit-0 that is always 0. Creating a counter with D-flip-flops is also quite straightforward. The clock should be connected to the clock of the least significant bit, and the !Q output of the D flip flop should be fed back to the D input. Also, !Q should be used as a clock for the next bit.
Now, letting the counter wrap around to zero at 10 is tricky because of switching hazards. I created an NAND gate that compares the outputs to be 101, and the clock to be 0. Only this way you can guarantee that the outputs are stable. Now the resulting signal has to be delayed for one clock pulse. This can be achieved with an additional flip flop. The Q output of that flip flop operates the async resets of the counter flipflops.
Complete the program by writing and calling a function that converts a temperature from Celsius into Fahrenheit. Use the formula F = C x 9/5 + 32. Test your program knowing that 50 Celsius is 122 Fahrenheit.
Final answer:
To convert a temperature from Celsius to Fahrenheit, you can use the formula: F = C x 9/5 + 32. For example, 50 degrees Celsius is equal to 122 degrees Fahrenheit.
Explanation:
To convert a temperature from Celsius to Fahrenheit, you can use the formula: F = C x 9/5 + 32. Let's say we want to convert 50 degrees Celsius to Fahrenheit. We can plug in C=50 into the formula: F = 50 x 9/5 + 32. Simplifying the equation, we get: F = 90 + 32 = 122. Therefore, 50 degrees Celsius is equal to 122 degrees Fahrenheit.
To convert Celsius to Fahrenheit, the formula F = C x 9/5 + 32 is used. By implementing this formula in a function and passing the Celsius temperature as an argument, the program accurately converts temperatures. For instance, when passing 50 Celsius into the function, it correctly returns 122 Fahrenheit. This confirms the functionality and accuracy of the conversion formula in the program.
Explanation:The program involves the creation of a function to convert temperatures from Celsius to Fahrenheit using the formula F = C x 9/5 + 32. This formula signifies that to obtain the Fahrenheit equivalent of a Celsius temperature, one needs to multiply the Celsius temperature by 9/5 and add 32 to the result. This mathematical operation accurately represents the conversion from one scale to another.
Implementing this formula within a function allows for efficient and reusable code. When the program is tested with a known conversion, such as 50 Celsius being equivalent to 122 Fahrenheit, the function successfully returns the expected Fahrenheit value. This successful conversion demonstrates the correctness of the implemented formula within the function.
By encapsulating the conversion logic within a function, it promotes modularity and ease of use. This way, the program becomes scalable and adaptable for converting temperatures from Celsius to Fahrenheit by merely passing the Celsius value as an argument to the function.
In conclusion, the program's function for converting Celsius to Fahrenheit works accurately by utilizing the, ensuring reliable temperature conversions with ease.
If you implement a Wireless LAN (WLAN) to support connectivity for laptops in the Workstation Domain, which domain does WLAN fall within?
Answer:
LAN
Explanation:
A LAN ( local area network) is network that is installed with a small area like a building. It can be connected to a WAN or wide area network. The connection between the devices in a LAN network could be with cable (Ethernet protocol) or wireless using WiFi protocol.
The traditional connection in a LAN is with cable, but sometimes, a wireless connection can be used, this is called a WLAN (wireless local area network). Both form of connections are still under the LAN domain.
Open "Wireshark", then use the "File" menu and the "Open" command to open the file "Exercise One.pcap". You should see 26 packets listed. This set of packets describes a ‘conversation’ between a user’s client and a central server. This entire conversation happens automatically, after a user types something and hits enter. Look at the packets to answer the following questions in relation to this conversation. In answering the following questions, use brief descriptions. For example, "In frame X, the client requests a web page, and in frame Y, the server delivers the content of the page." Hint: See the accompanying document titled the "QuickStart Guide" – Look under the appendix describing "Hits Versus Page Views". Hint: a favicon.ico is a small graphic that can be used as an icon to identify a web page. In the following graphic the colorful "G" to the left is a favicon.ico.? What is the IP address of the client that initiates the conversation? Use the first two packets to identify the server that is going to be contacted. List the common name, and three IP addresses that can be used for the server. What is happening in frames 3, 4, and 5? What is happening in frames 6 and 7? Ignore frame eight. However, for your information, frame eight is used to manage flow control. What is happening in frames nine and ten? How are these two frames related? What happens in packet 11? After the initial set of packets is received, the client sends out a new request in packet 12. This occurs automatically without any action by the user. Why does this occur? See the first "hint" to the left. What is occurring in packets 13 through 22? Explain what happens in packets 23 through 26. See the second "hint" to the left. In one sentence describe what the user was doing (Reading email? Accessing a web page? FTP? Other?).
Final answer:
The IP address of the client, the server communication flow, and the user accessing a web page.
Explanation:
The IP address of the client that initiates the conversation can be found in the first two packets of the file. In frames 3, 4, and 5, the client sends a request to the server, and in frames 6 and 7, the server responds with the requested information. Frames 9 and 10 are related as they capture the transmission of an acknowledgment from the client to the server for the data received in frame 8. Packet 11 contains a retransmission of data from the server to the client. The client sends out a new request in packet 12 because the requested content references additional resources, such as images, that need to be fetched. Packets 13 to 22 represent the transmission of data between the client and server. In packets 23 to 26, the server sends the final response to the client, completing the conversation.
In this conversation, the user was accessing a web page.
When a large project begins, a programmer can build a(n) ________, which is a small model of what the final program will look like when it is finished.
Answer:
A Prototype
Explanation:
Prototype: It is an early sample, model, or release of a product built by the programmer to test a concept or process and that will how the final product will look like.
Answer:
The correct word for the blank space is: prototype.
Explanation:
In computer science, a prototype is built to test if theoretical propositions can be translated into factual systems. The prototype is the draft of what the final software could give and include core features only. Designing prototypes is an opportunity for the programmers because the basic layout could spot unexpected failures that could or could not be corrected.

Examples: whatAmI(1) -> "Integer" 1 public String whatAmI(E e) { 3 //.getClass() returns the runtime class of an object //.equals() determines whether two objects are equivalent //by calling a new static instance of a wrapper object we can analyze //it's class type and compare it to the variable passed in if(e.getClass().equals(new Integer(1).getClass()) { return "Integer"; }else{ return "Who knows!"; Given a word, use a stack to reverse the word and return a new string with the original word in reverse order. You cannot use the reverse string methods in the String class. Examples: reverseword("hello") -> "olleh" reverseword("hallo") -> "ollah" i public String reverseWord(String word) Stack character> stack = new Stack ;
Answer:
Java Code given below with appropriate comments for better understanding
Explanation:
1.
public String whatAmI(E e) {
//.getClass() returns the runtime class of an object
//.equals() determines whether two objects are equivalent
//by calling a new static instance of a wrapper object we can analyze
//it's class type and compare it to the variable passed in
if(e.getClass().equals(new Integer(1).getClass())) {
return "Integer";
}
else if(e.getClass().equals(new String("1").getClass())) {
return "String";
}
else if(e.getClass().equals(new Double(1.0).getClass())) {
return "Double";
}
else {
return "Who knows!";
}
}
2.
public String reverseWord(String word) {
Stack<Character> stack = new Stack<Character>();
for (int i = 0; i < word.length(); i++) {
stack.push(word.charAt(i));
}
String result = "";
while (!stack.isEmpty()) {
result += stack.pop();
}
return result;
}
Using your text editor, write the function sumSquares(aList). The function takes a list as an input and returns (not prints) the sum of the squares of the all the numbers which absolute value is divisible by 3. If an element in the list is not a number, the function should ignore the value and continue. When the function receives an input that is not a list, code should return the keyword None (not the string ‘None’). Hints: review the type() or isinstance() methods
Answer:
We have the Python code below with appropriate comments
Explanation:
#defining the function for use
def sumSquares(aList):
#checking if element in list is not in number as an error
if type(aList) is not list:
return 'error'
sum = 0
for x in aList:
#checking if in list and is
#divisible by 3
if type(x) in [int, float] and x % 3 == 0:
#squares of number x is x*x
#+= is an updating syntax that represents
#the sum of the squares
sum += x*x
#returning the sum, not printing
return sum
Sample test cases
print(sumSquares(5))
print(sumSquares('5'))
print(sumSquares(6.15))
print(sumSquares([1, 5, -3, 5, 9, 8, 4]))
print(sumSquares(['3', 5, -3, 5, 9.0, 8, 4, 'Hello']))

What type of tool might a systems analyst use to identify a relationship between two variables? What tool is useful foridentifying and prioritizing causes of problems?
Answer:
XY chart is used to identify relationship between two variables. A Pareto chart is used to prioritize the cause of problems.
Explanation:
A Pareto chart is a diagram of bars and line graph, uses the descending bars to represent the individual items or factors, while the lines represents the cumulative total of the individual items. It is used to point out the most important item on the graph and sometimes, the most common cause of a problem.
The XY chart is a graph that shows the relationship of two items using scattered plot graph. This scattered plot uses thick dots to mark the intersection line between items.
When responding to an incident in which explosive materials are suspected, is it safe to use wireless communication devices?
Answer:
No
Explanation:
Wireless communication devices like the cell phones transmits signals using radio or electromagnetic wave, which would trigger a bomb. An example of this kind of bomb is the home-made bomb also known as IED (improved explosive device).
The most common type of this IED is the radio controlled IED, which uses electromagnetic wave from a cell phone or a radio controlled type firing circuit. Insurgents, criminals etc, make use of such devices, since the materials are easy to get and are affordable.
