Answer:
An LCD projector is a type of video projector for displaying video, images, or computer data on a screen or other flat surface. It is a modern equivalent of the slide projector or overhead projector.
It's different because in a computer display, the screen is the physical surface on which visual information is presented. This surface is usually made of glass.
Explanation:
A digital projector is a device that projects video or images onto a large screen, suitable for shared viewing in larger settings. It differs from a computer screen in terms of size, portability, shared viewing capabilities, image quality, source connectivity, and adjustments.
A digital projector is a device that takes a video or image signal from a computer, DVD player, or other multimedia source and projects it onto a large screen or surface.
The key differences between a digital projector and a computer screen:
Size: The most obvious difference is the size of the display.
Portability: Computer screens are generally fixed and not easily portable, whereas digital projectors are often designed for mobility.
Shared Viewing: A computer screen is designed for individual or small group viewing at close distances, while a digital projector is meant for larger audiences.
Image Quality: Digital projectors vary in imagequality, and high-quality projectors can offer impressive resolution and brightness suitable for movie screenings or professional presentations.
Source Connectivity: Both a computer screen and a digital projector can receive input from computers and other multimedia sources.
Placement and Adjustment: Digital projectors often provide manual or automatic keystone correction and focus adjustments to ensure the projected image remains proportional and clear on the screen or surface.
Hence, a digital projector is a device used to project large-scale images or video onto a screen or surface, suitable for shared viewing in larger settings.

b) source address
c) type of application
The most significant protocol at layer 3, often known as the network layer, is the Internet Protocol, or IP.The IP protocol, the industry standard for packet routing among interconnected networks, is the source of the Internet's name. Thus, option C is correct.
Application-layer firewalls operate at the TCP/IP stack's application level (all browser traffic, or all telnet or ftp traffic, for example), and thus have the ability to intercept any packets going to or from an application. They stop different packets (usually dropping them without acknowledgment to the sender).
Firewalls are frequently positioned at a network's edge. An external interface is the one that is located outside the network, while an internal interface is the one that is located inside the firewall.
Therefore, The terms “unprotected” and “protected,” respectively, are sometimes used to describe these two interfaces.

The answer is c) type of application
Answer:
White spaces or WHITESPACE
calc_average - this function should accept 8 test scores as arguments and return the average of the scores per student
determine_grade - this function should accept a test score average as an argument and return a letter grade for the score based on the following grading scale:
90-100 A
80-89 B
70-79 C
60-69 D
Below 60 F
In this exercise we have to use the computer language knowledge in python to write the code as:
the code is in the attached image.
In a more easy way we have that the code will be:
def calc_average(name):
score = []
sum = 0
for j in range(8):
inp = int(input("Test Score"+str(j+1)+": "))
score.append(inp)
sum = sum + inp
if inp>=90 and inp<=100:
print("A")
elif inp>=80 and inp<90:
print("B")
elif inp>=70 and inp<80:
print("C")
elif inp>=60 and inp<70:
print("D")
else:
print("F")
avg = sum/8
print("Result Details of "+name)
print("Average Score: "+str(avg))
return avg
def determine_grade(result):
if float(result) >= 90.0 and float(result) <= 100.0:
print("Letter Grade: A")
elif float(result) >= 80.0 and float(result) <90.0:
print("Letter Grade: B")
elif float(result) >= 70.0 and float(result) < 80.0:
print("Letter Grade: C")
elif float(result) >= 60.0 and float(result) < 70.0:
print("Letter Grade: D")
else:
print("Letter Grade: F")
print(" ")
for i in range(2):
name = input("Student Name: ")
result = calc_average(name)
determine_grade(result)

Answer:
The program doesn't make use of comments (See Explanation)
Also the source code is attached as image to enable you see the proper format and indexing of the source code
The program using python is as follows
def calc_average(name):
score = []
sum = 0
for j in range(8):
inp = int(input("Test Score"+str(j+1)+": "))
score.append(inp)
sum = sum + inp
if inp>=90 and inp<=100:
print("A")
elif inp>=80 and inp<90:
print("B")
elif inp>=70 and inp<80:
print("C")
elif inp>=60 and inp<70:
print("D")
else:
print("F")
avg = sum/8
print("Result Details of "+name)
print("Average Score: "+str(avg))
return avg
def determine_grade(result):
if float(result) >= 90.0 and float(result) <= 100.0:
print("Letter Grade: A")
elif float(result) >= 80.0 and float(result) <90.0:
print("Letter Grade: B")
elif float(result) >= 70.0 and float(result) < 80.0:
print("Letter Grade: C")
elif float(result) >= 60.0 and float(result) < 70.0:
print("Letter Grade: D")
else:
print("Letter Grade: F")
print(" ")
for i in range(2):
name = input("Student Name: ")
result = calc_average(name)
determine_grade(result)
Explanation:
def calc_average(name): -> Declares the function calc_average(name); It accepts local variable name from the main function
score = []
-> Initialize an empty list to hold test scores
sum = 0
-> Initialize sum of scores to 0
for j in range(8):
-> Iterate from test score 1 to 8
inp = int(input("Test Score"+str(j+1)+": "))
-> This line accepts test score from the user
score.append(inp)
-> The user input is then saved in a lisy
sum = sum + inp
-> Add test scores
The following lines determine the letter grade of each test score
if inp>=90 and inp<=100:
print("A")
---
else:
print("F")
avg = sum/8 -> Calculate average of the test score
The next two lines prints the name and average test score of the student
print("Result Details of "+name)
print("Average Score: "+str(avg))
return avg
-> This line returns average to the main method
The following is the determine_grade method; it takes it parameter from the main method and it determines the letter grade depending on the calculated average
def determine_grade(result):
if float(result) >= 90.0 and float(result) <= 100.0:
print("Letter Grade: A")
elif float(result) >= 80.0 and float(result) <90.0:
print("Letter Grade: B")
elif float(result) >= 70.0 and float(result) < 80.0:
print("Letter Grade: C")
elif float(result) >= 60.0 and float(result) < 70.0:
print("Letter Grade: D")
else:
print("Letter Grade: F")
print(" ")
for i in range(2):
-> This is the main method
name = input("Student Name: ") -> A local variable stores name of the student
result = calc_average(name) -> store average of scores in variable results
determine_grade(result)-> Call the determine_grade function

Answer: A) Battery backup
Explanation:
A battery backup are used to provide the source of power backup to various hardware components and desktop computers. In many cases, the devices are plugged into UPS ( uninterruptible power supply) for backup power and it is also depend upon the size of the UPS.
All the battery backups are located inside so that is why, the devices are heavy in weight. Usually, the battery backup front required additional button for performing various functions.
And the battery backup devices are manufacture by using the varying degree of backup abilities.
