Even when unplugged, a CRT (Cathode Ray Tube) monitor can store a lot of electricity. The capacitors within CRT monitors can store enough power to be fatal, thus you should never open one.
What does CRT stand for?An electron beam striking a phosphorescent surface creates images in a cathode-ray tube (CRT), a specialized vacuum tube. CRTs are typically used for desktop computer displays. The "picture tube" in a television receiver is comparable to the CRT in a computer display.
What characteristics does CRT have?Flat screen, touch screen, anti-reflective coating, non-interlaced, industrial metal cabinet, and digital video input signal are typical features of CRT monitors. As opposed to the typically curved screen found in most CRT displays, the monitor's screen can be (almost) flat.

Answer:
CRT monitor
Explanation:
A cathode ray tube (CRT) monitor can store large amounts of electricity, even when unplugged. You should never open a CRT monitor, as the capacitors within the CRT can store enough electricity to be lethal.
LCD monitors do not use large capacitors and are much safer to work on than CRT monitors (although the CCFL backlight has mercury vapor in it, which could be harmful if the tube is broken).
DVD optical drives and hard disk drives do not store electricity in sufficient quantity to be harmful.
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.
Write a program that will ask the user to enter the amount of a purchase. The program should then compute the state and county sales tax. Assume the state sales tax is 5 percent and the county sales tax is 2.5 percent.in python
Answer:
This program first prompts the user to enter the amount of the purchase. It then defines the state and county sales tax rates as constants. It calculates the state and county sales tax amounts by multiplying the purchase amount by the appropriate tax rate. Finally, it calculates the total sales tax by adding the state and county sales tax amounts together, and prints the results.
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.
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.")

In the flag, the RGB values next to each band indicate the band's colour.
RGB: 11111101 10111001 00010011
RlGB: 00000000 01101010 01000100
RGB: 11000001 00100111 00101101
First, convert the binary values to decimal. Then, to find out what colours these values correspond to, use the Colour names' handout (ncce.io/rep2-2-hw) or look up the RGB values online. Which European country does this flag belong to?
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.

solve the MRS y,x = 12 mean?
Answer:
Explanation:
The MRS (Marginal Rate of Substitution) is a concept from microeconomics that describes the rate at which one good (in this case, y) can be substituted for another good (in this case, x) while still maintaining the same level of utility or satisfaction for the consumer.
The equation you provided, MRS y,x = 12, tells us that in order for a consumer to maintain the same level of satisfaction, they would be willing to give up 12 units of good y in exchange for 1 unit of good x. This means that, in this specific case, the consumer values good y 12 times more than good x.
It's important to keep in mind that the MRS is a concept that can vary depending on the context and the consumer. The value of the MRS can change depending on the consumer's preferences, the availability of the goods, and the prices of the goods, among other factors.
On this equation alone, I can't confirm what exactly it refers to as more information about the context and the goods themselves is needed, also to make this equation valuable, it's should be done in a utility function or optimization problem in order to give some meaning to the number 12.

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.

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.

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.
