Answer:
Carrier Sense Multiple Access / Collision Detection abbreviated as CSMA/CD, is known as a set of rules that determines how a network devices tends to respond when devices attempt to use data channel simultaneously. It tends to work by detecting a collision in the medium and backing off as necessary. Consider a LAN with several hosts. When one of them transmits a frame, it tends to listens on medium in order to check whether medium is busy.
What are data structures and algorithms? Why are they important to software developer?
Explanation:
Data structure is a way of gathering and organizing the data in such a way that we can perform operation on the data very efficiently.There are different types of data structures such as :-
ArraysLinked listStacksQueuesTreesGraphsThese are the basic data structures.
Algorithm:-It is a finite set of instructions written to accomplish a certain task.An algorithm's performance is measured on the basis of two properties:-

c++ 2.30 LAB: Phone number breakdown Given a long long integer representing a 10-digit phone number, output the area code, prefix, and line number, separated by hyphens. Ex: If the input is: 8005551212 the output is: 800-555-1212 Hint: Use % to get the desired rightmost digits. Ex: The rightmost 2 digits of 572 is gotten by 572 % 100, which is 72. Hint: Use / to shift right by the desired amount. Ex: Shifting 572 right by 2 digits is done by 572 / 100, which yields 5. (Recall integer division discards the fraction). For simplicity, assume any part starts with a non-zero digit. So 999-011-9999 is not allowed. LAB
Answer:
#include <iostream>
using namespace std;
int main()
{
//declare variable to store phone numbers,its area code, prefix and line number.
long phone_number;
int area_code, prefix,line_number;
cout<<"Enter 10-digit phone number:"<<endl;
//input 10-digit phone number
cin>>phone_number;
//logic to find area_code, prefix, and line_number.
area_code = phone_number/10000000;
prefix = (phone_number/10000)%1000;
line_number = phone_number%10000;
//output phone number in asked format.
cout<<area_code<<"-"<<prefix<<"-"<<line_number<<endl;
return 0;
}
Output:
Enter 10-digit phone number:
8005551212
800-555-1212
Explanation:
In the above program 10 digit phone number entered by user will be stored in the variable phone_number.
Then using this phone_number variable area_code, prefix, and line number are calculated using the following logic:
area_code = phone_number/10000000;
prefix = (phone_number/10000)%1000;
line_number = phone_number%10000;
Finally these area_code, prefix, and line_number are displayed with hyphen in between using cout statement.
The C++ program reads a 10-digit phone number, then extracts and prints its area code, prefix, and line number, separated by hyphens. It uses division and modulo operations to isolate the desired digits, ensuring non-zero starting digits for simplicity.
Here's a C++ solution for your problem:
```cpp
#include <iostream>
using namespace std;
int main() {
long long phoneNumber;
cout << "Enter a 10-digit phone number: ";
cin >> phoneNumber;
int areaCode = phoneNumber / 10000000;
int prefix = (phoneNumber / 10000) % 1000;
int lineNumber = phoneNumber % 10000;
cout << "Phone number breakdown: " << areaCode << "-" << prefix << "-" << lineNumber << endl;
return 0;
}
```
This C++ program reads a 10-digit phone number as a long long integer. It then extracts the area code, prefix, and line number using the given hints and prints them separated by hyphens.

How are IP addresses usually written?
Explanation:
There are two versions of Internet Protocol(IP) present in which the IP address are written which are IPv4 and IPv6.The numbers in IPv4 are 32 bit long while in IPv6 the numbers are 128 bits long.
So let's see IPv4 addresses
IP addresses are written in human readable form.There are 4 groups of 8 bits which represent the corresponding decimal numbers.These groups are separated by (.) .Since there are 8 bits hence the numbers range is 0-255.
for ex:- 124.45.65.210
There are 3 dots the numbers are in the range of 0-255.There should be no leading zeroes present in the IP address.

If your database is in archivelog mode, how can you force an archive?
A. Issue an alter database switch logfile command.
B. Issue an alter system switch logfile command.
C. Issue an alter system log_archive_start command.
D. There is no command to force an archive; they happen automatically.
Answer: (B) Issue an alter system switch logfile command.
Explanation:
When the database is in the archive log mode then, the issue in the alter system switch logfile command force the particular switch. It basically produce achieve redo log which is smaller in the size by the dedicated size of the parameter log buffer.
It also govern the particular size of the RAM (Random access memory) buffer by redo log. This command is basically faster to return in the program by the use of redo log.
On the other hand, all the options are incorrect as this command only alter the system and does not alter the database. Therefore, Option (B) is correct.

What are the advantages and disadvantages of using wireless communications? What are the advantages and disadvantages of using wired communications? Under what conditions is a wireless channel preferred over a wired channel? [Hint: use a table to compare and contrast the advantages and disadvantages of wired versus wireless communications.] Please give sources if possible
Answer:
Advantages of wireless communication:-
Flexibility in transferring the message through communication for which the sender and receiver can be in any place.Speed of the communication is accurate and fastDue to no wiring , the cost of the wireless communication is less.Disadvantages of wireless communication:-
The security is less as the data can be accessed by unauthorized sources at times.The setting up of wireless communication complex and expensive.Advantages of wired communication:-
Simple configurationHigher bandwidth is present in the cableHigh reliabilityDisadvantages of wired communication:-
Mobility is present for communicationInstallation requires lot of time due to cablingRequires extra devices for covering large areas for communicationWireless communication is more preferable than wired communication in the conditions like communication connection that should face low damage and longer life which is not present in cable connection as they break or get disrupted.The flexibility of moving while communication is required by most people so, they use wireless communication .
The advantages and disadvantages of wireless communications include portability, ease of installation, and flexibility as advantages, while they suffer from potential security issues, interference, and varying reliability. On the other hand, wired communications boast high stability, speed, and security but lack the mobility and ease of deployment that wireless offers. Wireless channels are preferred over wired when mobility, ease of setup, or physical cabling constraints are considerations.
Wireless communications offer the key advantages of mobility, ease of installation, and the ability to connect multiple devices without the need for physical cables. However, disadvantages include security concerns, as wireless communications can be more susceptible to unauthorized access, interference from other devices or physical barriers that can disrupt signals, and potentially less reliability in terms of consistent connectivity.
Wired communications, by contrast, offer greater security, as physical access to the network is required for connectivity, and are typically more stable and faster, as they are less likely to be affected by interference. The main disadvantages include the lack of mobility, as devices are tethered to specific locations by cables, and challenges in the installation process, especially in areas where running cables is difficult or impractical. Wireless channels are often preferred in situations where mobility is necessary, such as in conference rooms or public spaces, where devices are frequently moved or added, and where installing cables would be difficult or costly.
What is the difference between a class and an object?
Explanation:
The difference between a class and an object is very simple a class is a template for objects.A class contains objects,methods,constructors,destructors. While an object is a member of the class or an instance of the class. for ex:-
#include<iostream>
using namespace std;
class car
{
public:
string color;
int numgears;
int engine capacity_cc;
bool ispetrol;
car(string color,int numgears,int engine capacity_cc,bool ispetrol)
{
this->color=color;
this->numgears=numgears;
this->capacity_cc=capacity_cc;
this->ispetrol=ispetrol;
}
};
int main()
{
car volvo = new car("red",6,2500,false);
return 0;
}
In the example we have class car and it's object is volvo.
Final answer:
In object-oriented programming, a class is a blueprint for creating objects that share similar properties and behaviors. An object, on the other hand, is an instance or a specific occurrence of that class. It represents a real-world entity and holds the values for the attributes defined in the class.
Explanation:
In object-oriented programming, a class is a blueprint for creating objects (instances) that share similar properties and behaviors. It defines the attributes (data) and methods (functions) that objects of that class will have. A class is like a template or a cookie cutter, while an object is an instance or a specific occurrence of that class. It represents a real-world entity and holds the values for the attributes defined in the class.
Let's take a car as an example. The class for a car would define its properties, such as color, brand, and year, as well as its behaviors, such as accelerating, braking, and turning. An object of this car class would be a specific car, like a red Toyota Camry from 2020, which has its unique values for the properties defined in the class.
How many strings of eight lower-case English letters are there that contain the two letters bg, in that order, with the further constraint that no letters can be repeated?
Answer: 678,363,840
Explanation:
Hi!
The "bg" part of the string could be in 7 possible positions within the string. If we number the characters in the string from 0 to 7, the "b" of "bg" could be in positions 0 to 6.
We need to count the possibilities for the other 6 characters. They can be any of the 26 lower-case letters, but not b nor g, because no letters can be repeated. So we can choose 6 letters from 24 letters, without repetition, and the order is important. The number of such combinations is:
[tex]n = 24,\; m = 6\\\frac{n!}{(n-m)!} = \frac{24!}{18!} = 96,909,120[/tex]
For the total number of strings, we have to multiply with the 7 possible position of "bg". Then, the final number is 678,363,840

What is a milestone? Provide a few examples of milestones.
Answer:
A milestone is a significant progress point within your project. Milestones' main purpose is to set goals you have to achieve in order to succeed and complete your project
Explanation:
-Example 1-
You have to write a report for your project. This report contains introduction, problem background, results, and recommendations. The milestones for writing your report could be:
Milestone 1: introduction section is completed
Milestone 2: problem background section is completed
Milestone 3: results section is completed
Milestone 4: recommendations section is completed
-Example 2-
You have to design a webpage that allows the user to login, enters his/her name, and logout. The milestones in this case could be:
Milestone 1: login functionality is completed
Milestone 2: text field for typing the name is placed
Milestone 3: submit name button functionality is completed
Milestone 4: logout button functionality is completed
Milestone 5: all components of the webpage are fully integrated
You might think the goals in these examples can be set differently, and that is true. The definition of the milestones is in general subjective and it depends on how you design the steps you want to follow to complete your project. You might also want to add these milestones to a timeline so you have an estimated schedule of the development of your project.
A milestone is a significant event or stage that marks progress in development, used to evaluate skill or project achievement. Examples include motor skills like walking, language development like the first word, and project management deliverables.
A milestone is a significant event or point in development that marks an important stage in a project, process, or a person's life. They often serve as indicators of progress and can be used to evaluate achievement or skill level in various domains.
Examples of Milestones:
Motor milestones: These refer to crucial developmental steps in an individual's motor skills, like sitting up, crawling, and walking.
Language milestones: These are critical steps involved in the development of language skills, such as the onset of babbling, the first word, and the combining of words.
Project milestones: These might include deliverables established, a timeline for when remaining work will be completed, and noting any problems that may affect project scope or direction.
Milestones are also used in different contexts, such as educational achievements (like graduating from school), professional development (like receiving a promotion), or personal growth (like buying a first home). In project management, they often involve establishing a direct reference to milestones or deliverables, scheduling the completion of remaining tasks, and identifying any issues that could impact the project's trajectory. Effective use of milestones helps in keeping projects on track and allows for the evaluation of progress over time, which is crucial for success.

What is the reason of non-deterministic (indeterminate) behavior of concurrent programs?
Answer: Concurrent programs are the programs that execute at the same point of time. They are simultaneous in nature with other concurrent programs.They are executed with the help of threads to achieve the concurrency without the issue of scheduling. They are consider long running programs.
The program that has the low execution time compared with all other programs gets executed first.If the case of no progress is seen then another thread is executed.This type of execution gives the non- deterministic situation in which the possibility of leading completion of any particular program cannot be determined.

Explanation: System development life cycle is the cycle that is responsible for the functioning of the system's operation.The steps of the system's cycle are development, evaluation,testing,analysis ,designing,documentation and implementation.These steps are necessary for the successful conduction of the system.
The accomplishment of the these steps are dependent on each other. The software or hardware components have to go through each step to get evaluated properly. Thus the accomplishment of each step is based on the complete cycle.Thus the statement given is false.
Write a program that takes as input two opposite corners of a rectangle: (x1,y1) and (x2,y2). Finally, the user is prompted for the coordinates of a third point (x,y). The program should print Boolean value True or False based on whether the point (x,y) lies inside the rectangle. If the point lies on the rectangle, the program should print False.
Answer:
A python3 script is given below
Explanation:
Hi there!
In this program it is assumed that the rectangle will always be parallel to the x and y axis
# First we define three lists where the coordinates will be stored
# The notrect variable will help us if the p1 and p2 coordinates are along the same axis and therefore the will not make a rectangle,in the assumed sense
p1, p2, p3 = [],[],[]
notrect = False
# In this for cycle we ask the user for the coordinates and check if the first two make a rectangle
for i in range(3):
if i<2:
x = float(input('Please write x'+str(i+1)+': '))
y = float(input('Please write y'+str(i+1)+': '))
else:
x = float(input('Please write x: '))
y = float(input('Please write y: '))
if i==0: p1 = [x,y]
elif i==1: p2 = [x,y]
else: p3 = [x,y]
# If they do not make the rectangle we no longer ask for the third and exit the program
if p1 and p2:
if p1[0] == p2[0] or p1[1] == p2[1]:
notrect = True
print('These ponits does not make a rectangle')
break
#If notrect = True we say Bye to the user and nothing else happens
if notrect:
print('Bye')
# If they do make the rectangle we save the x and y coordinates of the rectangle separately, and sort them
else:
x = [p1[0],p2[0]]
y = [p1[1],p2[1]]
x.sort()
y.sort()
# If the x and y coordinates of the third point are between the x and y coordinates of the vertices of the rectangle the last point is indeed inside the rectangle, and print a True. Otherwise, we print a False
print((p3[0]>x[0] and p3[0]<x[1]) and p3[1]>y[0] and p3[1]<y[1])
The required codes are attached below:

. double x = 5; declares that x is a...............variable.
Answer:
x is a double type variable.
Explanation:
Here is x is a variable of type double which stores the value 5. The main purpose of a double datatype is storing the decimal point values. The precision of double datatype is two times more than the precision of float datatype. So on displaying the value of x in c++ it prints "5".
Following are the program of double datatype in c++
#include <iostream> // header file
using namespace std; // namespace
int main() // main function
{
double x=5; // variable declaration
cout<<x; // displaying the value of x
return 0;
}

What is back propagation?
Answer:
Back propagation is the algorithm which is basically used o improve the accuracy in the machine leaning and data mining. It is one of the most important tool in the mathematics to check the prediction with high accuracy.
The back propagation is also known as backward propagation and it is mainly used in the ANN (Artificial neural network).
The important features of the back propagation is that it has high efficiency for improving the networks. It is also recursive and iterative methods and ability to perform various tasks.
Final answer:
Back propagation is an algorithm used to train neural networks by minimizing the output error through gradient descent. It involves adjusting the weights of neurons based on the error gradient, which is calculated using the chain rule. The process leverages activation functions to allow the learning of complex patterns.
Explanation:
Back propagation is a fundamental algorithm used in the training of artificial neural networks. It is a supervised learning technique that adjusts the weights of the neurons in the network. The main goal of back propagation is to minimize the error in the output of the neural network by propagating the error backward through the network and updating the weights accordingly.
The process begins by feeding the network an input and letting it pass through the layers to produce an output. This output is then compared with the desired output, and the difference between them is the error. Back propagation takes this error and calculates the gradient of the loss function with respect to each weight in the network using the chain rule of calculus. The weights are then adjusted in the opposite direction of the gradient to reduce the error. This is typically done using an optimization algorithm like gradient descent.
An important component of back propagation is the use of activation functions which add non-linear properties to the network, allowing it to learn more complex patterns. During back propagation, derivatives of these activation functions are vital as they are involved in calculating the gradients.
Overall, back propagation is an iterative process, where multiple epochs of training may be necessary to reach the desired level of accuracy.
Define and implement a method that takes a string array as a parameter and returns the length of the shortest and the longest strings in the array
Answer:
#HERE IS CODE IN PYTHON
#function to find length of shortest and longest string in the array
def fun(list2):
#find length of shortest string
mn=len(min(list2))
#find length of longest string
mx=len(max(list2))
#return both the value
return mn,mx
#array of strings
list2 = ['Ford', 'Volvo', 'BMW', 'MARUTI','TATA']
# call the function
mn,mx=fun(list2)
#print the result
print("shortest length is:",mn)
print("longest length is:",mx)
Explanation:
Create an array of strings.Call the function fun() with array as parameter. Here min() function will find the minimum string among all the strings of array and then len() function will find its length and assign to "mn". Similarly max() will find the largest string and then len() will find its length and assign to "mx". Function fun() will return "mn" & "mx".Then print the length of shortest and longest string.
Output:
shortest length is: 3
longest length is: 5
Final answer:
The problem involves writing a Java method to find the lengths of the shortest and longest strings in an array. The method iterates through each string to update and find the minimum and maximum lengths. It returns these lengths as an integer array.
Explanation:
To tackle the problem of finding the lengths of the shortest and longest strings in an array, we'll use a programming approach. Let's assume we are using Java for this solution. The method will iterate through the array, comparing the lengths of each string to find the minimum and maximum lengths.
Here is a simple Java method that accomplishes this:
public static int[] findShortestAndLongestStringLen(String[] array) {
if (array == null || array.length == 0) return new int[] {-1, -1}; // Handle empty or null array
int minLength = Integer.MAX_VALUE;
int maxLength = Integer.MIN_VALUE;
for (String str : array) {
if (str.length() < minLength) {
minLength = str.length();
}
if (str.length() > maxLength) {
maxLength = str.length();
}
}
return new int[] {minLength, maxLength};
}
This method initializes two variables, minLength and maxLength, with the maximum and minimum values an integer can have, respectively. It iterates through each string in the array, updating these values based on the length of each string. Finally, it returns an array of two integers: the shortest length found (minLength) and the longest (maxLength).
The ________ maps the software architecture created in design to a physical system architecture that executes it. (Points : 3) architectural diagram
sequence diagram
deployment diagram
state chart diagram
Answer:Deployment diagram
Explanation: Deployment diagram is the diagram that is used for displaying the hardware parts upon which the software architecture works.The main purpose of the diagram is showing the function and operations taking place through the deployment of the software system with the hardware.
These diagrams are made up of the nodes , interface, artifacts and other components. Other given options are incorrect because architectural diagram is for designing of the architecture of a system,sequence diagram is used for the sequential order display of system components and state chart diagram is the diagram that shows the status of the parts of the operating system.
Therefore, the correct option is deployment diagram.
