Answer:
To convert the binary values to decimal, you can use the following steps:
Start with the rightmost digit and assign it the value of 0.
For each subsequent digit moving from right to left, double the value of the previous digit and add the current digit.
For example, to convert the first binary value, 11111101, to decimal:
10 + 02 + 04 + 08 + 016 + 132 + 164 + 1128 = 253
So the first binary value, 11111101, corresponds to the decimal value 253.
Using this method, you can convert the other binary values to decimal as well. To find out what colours these values correspond to, you can use the Colour names' handout or look up the RGB values online.
To determine which European country this flag belongs to, you can try looking up the colours and seeing if they match any known flags. Alternatively, you could try searching for flags of European countries and see if any of them match the colours you have identified.
A table student consists of 5 rows and 7 columns. Later on 3 new attributes are added and 2 tuples are deleted. After some time 5 new students are added. What will be the degree and cardinality of the table?
Answer:
The degree of a table refers to the number of attributes (columns) it has. In the case you described, after the 3 new attributes are added, the degree of the table would be 7 + 3 = 10.
The cardinality of a table refers to the number of rows (tuples) it has. In the case you described, after 2 tuples are deleted, the cardinality of the table would be 5 - 2 = 3. After 5 new students are added, the cardinality would increase to 3 + 5 = 8.
How did the case Cubby v. CompuServe affect hosted digital content and the contracts that surround it?
Although CompuServe did post libellous content on its forums, the court determined that CompuServe was just a distributor of the content and not its publisher. As a distributor, CompuServe could only be held accountable for defamation if it had actual knowledge of the content's offensive character.
What is CompuServe ?As the first significant commercial online service provider and "the oldest of the Big Three information services," CompuServe was an American company. It dominated the industry in the 1980s and continued to exert significant impact into the mid-1990s.
CompuServe serves a crucial function as a member of the AOL Web Properties group by offering Internet connections to budget-conscious customers looking for both a dependable connection to the Internet and all the features and capabilities of an online service.
Thus, CompuServe could only be held accountable for defamation if it had actual knowledge of the content's offensive character.

Write a program that will calculate the internal angle of an n-sided polygon from a triangle up
to a dodecagon. The output to the console should show what the random number chosen was
and the value of the internal angle. Remember to find the internal angle of a polygon use:
360°
n
The program that will calculate the internal angle of an n-sided polygon from a triangle upto a dodecagon is given below
import random
def internal_angle(n):
angle = 360 / n
return angle
n = random.randint(3, 12)
print("Random number chosen:", n)
angle = internal_angle(n)
print("Internal angle of a", n, "-sided polygon:", angle, "degrees")
What is the Python program about?The program uses the formula for calculating the internal angle of a polygon, which is 360° divided by the number of sides (n). It also generates a random number between 3 and 12 to represent the number of sides of the polygon, and uses this value to calculate the internal angle.
The program starts by importing the random library, which is used to generate a random number. Then, it defines a function called "internal_angle" that takes one parameter, "n", which represents the number of sides of the polygon.
Inside the function, the internal angle of the polygon is calculated by dividing 360 by n and storing the result in the variable "angle". The function then returns this value.
Therefore, It's important to note that the internal angle of a polygon would be correct as long as the number of sides is greater than 2.

PLS answer correctly...i will mark u as brainlyst!!!!!
Answer:
Explanation:
The biggest question now is how do we attract more women into the computer science field. Women need more encouragement, especially from teachers of both sexes and fellow students. Mentoring is a definite means to attract and keep women more interested in the field. Even just the support of other females present in a classroom setting can help boost the confidence in each other. Multiple studies have shown that the lack of women in computer science is very likely to start before college (Cohoon). They need this encouragement not only while taking college courses but also early on in their education. Females tend to be just as interested in science as men when they are young but their teachers and schools, who would have the most influence on them, aren’t doing their job in nurturing and identifying these women (Gurian). A possible solution to improving their confidence would be to have more mentors who can help attract and keep women interested in the field. The shortage of women in the computer science field has made it more difficult to have women in high positions. This makes it important for women who are in high positions to be mentors to all women interested. According to Joanne Cohoon a professor at the University of Virginia “CS departments generally retained women at comparable rates to men when the faculty included at least one woman; was mentored, and supervised female students; enjoyed teaching; and shared responsibility for success with their students”. It is also found that departments with no female faculty lost female students at high rates relative to men (Cohoon). Seeing other women in computer science can definitely raise confidence in women to continue or begin studying the subject. “In a new survey, 40 percent of women in the STEM fields… report that they were discouraged from their career choices, typically in college and often by their professors” (Downey). This data shows how we need more mentors willing to support women and that we are lacking teachers to help inspire young women into entering the field.
Since the beginning of computing most software and programs have been male-oriented. Video games were originally targeted at males with sport and violent themes with mostly male lead characters and limiting female roles like women who need to be rescued (Lynn). Early experiences with computers are important in shaping someone’s willingness to explore technology. “Playing with computer, console, and arcade games and educational ware can provide an introduction to computer literacy, creating familiarity and building confidence in skills” (Lynn, 145). Because computer science is so dominated by men, the software tends to be more male- friendly. To make software more appealing to girls, it should have low frustration levels, be challenging and be interactive (Lynn). By having more women in the field, women can create much more women-friendly software. Girls tend to prefer games where they can make things, rather than destroy them(Lynn). Recently more and more games have been produced that are more girl-friendly, like simulation games. The Sims is a video game where you create humans, animals and homes and has proved to be a big success with a female audience. A strategy to get more women to break outside the stereotype of women being less competitive than men would be to take games designed for boys and demand comparable female characters to empower them to be more competitive and assertive. Video games often become involved with computing as a byproduct of wanting to master gaming (Lynn).
Many boys tend to have more experience with computers at a younger age because of video games, when boys and girls are put together in a class to learn about computers the boys are already at a higher level, which is not encouraging to the women beginning at a lower level in the same class. Making more computer classes mandatory both in high school and at the college level will not only help women because of the increasing number of other female peers, but it can spark interest in women early on, helping teachers to identify students with aptitude.

Since you now have a good understanding of the new situation, write a new num_of_paths function to get the number of ways out. The function should take in a map of maze that Yee Sian sent to you and return the result as an integer. The map is a tuple of n tuples, each with m values. The values inside the tuple are either 0 or 1. So maze[i][j] will tell you what's in cell (i, j) and 0 stands for a bomb in that cell.
For example, this is the maze we saw in the previous question:
((1, 1, 1, 1, 1, 1, 1, 1, 0, 1),
(1, 0, 0, 1, 1, 1, 0, 0, 1, 1),
(0, 1, 1, 1, 0, 0, 1, 1, 1, 0),
(1, 1, 0, 1, 1, 1, 1, 0, 1, 1),
(0, 1, 0, 1, 0, 0, 1, 0, 1, 0),
(1, 0, 1, 1, 1, 1, 0, 1, 1, 1),
(0, 1, 1, 1, 1, 1, 1, 1, 1, 0),
(1, 0, 1, 0, 0, 1, 1, 0, 1, 1),
(1, 0, 1, 1, 1, 0, 1, 0, 1, 0),
(1, 1, 0, 1, 0, 1, 0, 1, 1, 1))
Note: You should be using dynamic programming to pass time limitation test.
Hint: You might find the following algorithm useful:
Initialize an empty table (dictionary), get the number of rows n and number of columns m.
Fill in the first row. For j in range m:
2.1 If maze[0][j] is safe, set table[(0, j)] to be 1 because there's one way to go there.
2.2 If maze[0][j] has a bomb, set table[(0, k)] where k >= j to be 0. Since one cell is broken along the way, all following cells (in the first row) cannot be reached.
Fill in the first column. For i in range n:
3.1 If maze[i][0] is safe, set table[(i, 0)] to be 1 because there's one way to go there.
3.2 If maze[i][0] has a bomb, set table[(i, 0)] and all cells under it to be 0. The reason is same as for the first row.
Main dynamic programming procedure - fill in the rest of the table.
If maze[i][j] has a bomb, set table[(i, j)] = 0.
Otherwise, table[(i, j)] = table[(i - 1, j)] + table[(i, j - 1)]
Return table[(n - 1, m - 1)]

List 2 or 3 visual aids that you might use during a speech on "Technology in the Classroom" (or a topic of your choosing) to illustrate your main points, and explain exactly how you plan to use them. (Site 1)
Answer:
Graphs or charts: I would use graphs or charts to illustrate the trend of technology usage in the classroom over time. For example, I could show a line graph that compares the percentage of classrooms that had no technology, limited technology, or full technology access in the past decade. This would allow the audience to see the increasing trend of technology adoption in the classroom and better understand the impact that technology is having on education.
Photos or videos: I would use photos or videos to provide concrete examples of how technology is being used in the classroom to enhance teaching and learning. For example, I could show a video of a teacher using a virtual reality headset to take her students on a virtual field trip to a museum, or I could show a series of photos of students using tablets or laptops to complete assignments and collaborate with their peers. These visual aids would help the audience to better understand the specific ways in which technology is being used in the classroom and how it is benefiting students and teachers.
Infographic: I would use an infographic to present a summary of the main points of my speech in a visually appealing and easy-to-understand format. The infographic could include bullet points or graphics that highlight the key benefits of technology in the classroom, such as increased engagement, improved learning outcomes, and enhanced collaboration. By presenting the information in this way, I could help the audience to quickly grasp the main points of my speech and better retain the information.

Create a program that asks the user to input three integers. After saving the values, the
program should identify the maximum and minimum from the three numbers. The output
should read
The minimum number entered was….
The maximum number entered was….
Here is a Python program that asks the user to input three integers and then outputs the minimum and maximum number:
The user is able to input grades and their weights, and calculates the overall final mark. The program should also output what you need to achieve on a specific assessment to achieve a desired overall mark. The program should be able to account for multiple courses as well.
I have done some pseudocode. So to double check, please provide pseudocode and python code.
I do plan to use homework, quizzes and tests for the grades portion and using the exam as part of the desired mark portion.
Answer:
Here is some pseudocode that outlines the steps for creating a program that calculates overall final marks and outputs the necessary grades for a desired overall mark:
DEFINE a function called "calculate_final_mark"
INPUT: grades (list), weights (list), desired_mark (float)
CREATE a variable called "overall_mark" and set it to 0
FOR each grade and weight in the grades and weights lists:
MULTIPLY the grade by the weight
ADD the result to the overall_mark
IF overall_mark equals the desired_mark:
OUTPUT "You have already achieved the desired mark."
ELSE:
CREATE a variable called "needed_mark" and set it equal to the desired_mark minus the overall_mark
OUTPUT "You need a" needed_mark "on your next assessment to achieve a" desired_mark "overall mark."
END the function
Here is the equivalent code in Python:
def calculate_final_mark(grades, weights, desired_mark):
overall_mark = 0
for grade, weight in zip(grades, weights):
overall_mark += grade * weight
if overall_mark == desired_mark:
print("You have already achieved the desired mark.")
else:
needed_mark = desired_mark - overall_mark
print(f"You need a {needed_mark} on your next assessment to achieve a {desired_mark} overall mark.")

Involving or based on a hypothesis: conjectural; involving or based on a postulated concept or theory. speculative arguments a fictitious circumstance.
How should a hypothetical example be written?The words or abbreviations "for instance," "for example," "i.e." or "e.g." are frequently used after a hypothetical example, albeit the latter two, as you are probably aware, will only come after a comma and won't initiate a new sentence like "for instance" or "for example." Use hypothetical examples with caution.
What is a fictitious person?The human whose existence is implied by other data rather than directly attested. theoretical individual hypothetical (adj.) is a 1580s term that means "based on or defined by a hypothesis, conjectural," from the Latinized form of the Greek word hypothesis, which means "pertaining to a hypothesis."

Use routers, Switches and Hubs to design a simple network for Maendeleo Institute of Technology having 240 employees. The Institute has five departments: Computer Science has 100 employees, Information Technology 60 employees, Accounts 40 employees, Human Resource has 20 employees and Marketing has 20 employees.
Required:
• Network topology showing five network that corresponds to five departments.
• Use Class C IP addresses (example 192.168.10.0/24) to show the subnet ID and broadcast ID of each department, the IP address must not overlap
• Consider Scalability
• Give reasons for your choice/ decisions
Answer:
To design a simple network for Maendeleo Institute of Technology with 240 employees, we could use a combination of routers, switches, and hubs.
Our network would consist of five separate networks, one for each department at the institute. We would use class C IP addresses, with a subnet mask of /24, to create the following subnets:
Computer Science department: 192.168.10.0/24
Information Technology department: 192.168.11.0/24
Account department: 192.168.12.0/24
Human Resource department: 192.168.13.0/24
Marketing department: 192.168.14.0/24
Each department would be connected to the network via a switch, which would allow for communication within the department and with other departments as needed. A router would be used to connect the individual department networks to the wider internet, and would also serve as a firewall to protect the network from external threats.
We would also include a hub in the network to allow for communication between devices within a department, as well as to provide additional connectivity and scalability.
Overall, our network design would provide each department with its own separate network, with the ability to communicate with other departments as needed. It would also be scalable, allowing for the addition of new devices and departments as the institute grows. The use of class C IP addresses and a /24 subnet mask would ensure that IP addresses do not overlap, ensuring efficient and reliable communication within the network.
Which computers were the first PCs with a GUI
MS-DOS
Linux
Windows
Mac
The earliest GUI-equipped PCs were Linux and Mac-based. These are the right answers to the question that was asked.
Which PCs had a graphical user interface (GUI) first?The first computer to employ a mouse, the desktop metaphor, and a graphical user interface (GUI), concepts Douglas Engelbart first introduced while at International, was the Xerox Alto, developed at Xerox PARC in 1973. It was the first instance of what is now known as a full-fledged personal computer.
When was the GUI added to Windows?Windows is based on what is known as a graphical user interface (GUI), which was created by Xerox in 1975 but was never used. The "window, icon, menu, and pointing device" (WIMP) combination will make up the majority of a typical GUI.

How do networks help protect data?
A) by shutting down at 5:00 p.m. each evening
B) by restricting access to department chairs
C) by scheduling regular backups
D) by preventing access by more than one person at a time
D) by preventing access by more than one person at a time
Networks use authentication and authorization to control access to data. They require that a person entering the network has valid credentials, such as a username and password, before they can access any data on the network. Once the credentials have been provided and verified, the user is typically given limited access to the data that is based on authorization rules set up within the network. This helps ensure that data is securely accessed by only those users that need to access it, preventing unauthorized access by multiple persons at once.
Write a Java program for user defined exception that checks the internal and external marks; if the internal marks is greater than 30 it raises the exception “Internal mark exceeded”; if the external marks is greater than 70 it raises the exception and displays the message “External mark exceeded”, Create the above exception and test the exceptions.
Answer:
class MarksException extends Exception {
public MarksException(String message) {
super(message);
}
}
public class Main {
public static void main(String[] args) {
try {
checkMarks(35, 80);
} catch (MarksException e) {
System.out.println(e.getMessage());
}
}
public static void checkMarks(int internal, int external) throws MarksException {
if (internal > 30) {
throw new MarksException("Internal mark exceeded");
}
if (external > 70) {
throw new MarksException("External mark exceeded");
}
}
}
