(Numerical Data Representation) How many bits per word are required to represent the following positive decimal integers: a.0 through 100b.0 through 255c.0 through 256d.0 through 10,000,000

Answer:

Question (1) the statements (i) and( iv) are logically equivalent and statements (ii) and (iii) are logically equivalent. Question (2) the statements (i) and (iii) are logically equivalent.

Explanation:

Solution

Question (1)

Now,

Lets us p as puppy in the house, and q as i am happy

So,

p : puppy in the house,  and q : i am happy

Thus,

The Statements

(i) so if there is a puppy in the house, I feel happy :  p -> q

(ii) If I am happy, then there is a puppy in the house : q -> p

(iii) If there is no puppy in the house, then I am not happy.   : ~ p -> ~q

(iv) If I am not happy, then there is no puppy in the house : ~q -> ~p

Hence, the statements (i) and( iv) are logically equivalent and statements (ii) and (iii) are logically equivalent.

Question (2)

Let us denote p as i am in school today, and q as i am in CSC231 class, and r as i am in civics class,

So,

p: i am in school today, q: i am in CSC231 class, r: i am in civics class,

Now,

(i) if I am in school today, then I am in CSC231 class  :p -> q

(ii) If I am not in school today, then I am not civics class  :~p -> ~r

(iii) If I am not in CSC231 class, then I am not in school today  :~q -> ~p

(iv) If I am in CSC231 class, then I am in school today  : q -> p

Therefore, the statements i) and iii) are logically equivalent.

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.

#SPJ3

the answer is Language

Answer:

Essayons

Explanation:

Answer:

x = input("Input a number ")

print(eval("x"))

print ("Type is:",type(x))

#Taking an float input

y = input("Input a number ")

print(eval("y"))

print ("Type is:",type(y))

#Taking an complex input

z = complex(input("Input a number "))

print(eval("z"))

print ("Type is:",type(z))

#Taking an List input

L_num = raw_input().split(",")

print(eval("L_num"))

print ("Type is:",type(L_num))

#Taking an tuple input.

T_num = raw_input().split(",")

print(eval("T_num"))

print ("Type is:",type(T_num))

Answer:

The screen protector may be interfering with the touch response

Explanation:

Screen protectors or commonly called screen guards are used to protect phone screens. In case they fall to the ground, these protectors act as shields to keep the phone screen from getting damaged. However screen protectors if not positioned or fixed properly may also cause hindrance to effective touch response as they become barriers to the touch screen.

Answer:

pkt = int(input("Pocket Number: "))

if pkt == 0:

   print("Green")

elif pkt >= 1 and pkt <=10:

   if pkt%2 == 0:

       print("Black")

   else:

       print("Red")

elif pkt >= 11 and pkt <=18:

   if pkt%2 == 0:

       print("Red")

   else:

       print("Black")

elif pkt >= 19 and pkt <=28:

   if pkt%2 == 0:

       print("Black")

   else:

       print("Red")

elif pkt >= 29 and pkt <=36:

   if pkt%2 == 0:

       print("Red")

   else:

       print("Black")

else:

   print("Error")

Explanation:

The program was written in Python and the line by line explanation is as follows;

This prompts user for pocket number

pkt = int(input("Pocket Number: "))

This prints green if the pocket number is 0

if pkt == 0:

   print("Green")

If pocket number is between 1 and 10 (inclusive)

elif pkt >= 1 and pkt <=10:

This prints black if packet number is even

   if pkt%2 == 0:

       print("Black")

Prints red, if otherwise

   else:

       print("Red")

If pocket number is between 11 and 18 (inclusive)

elif pkt >= 11 and pkt <=18:

This prints red if packet number is even

   if pkt%2 == 0:

       print("Red")

Prints black, if otherwise

   else:

       print("Black")

If pocket number is between 19 and 28 (inclusive)

elif pkt >= 19 and pkt <=28:

This prints black if packet number is even

   if pkt%2 == 0:

       print("Black")

Prints red, if otherwise

   else:

       print("Red")

If pocket number is between 29 and 36 (inclusive)

elif pkt >= 29 and pkt <=36:

This prints red if packet number is even

   if pkt%2 == 0:

       print("Red")

Prints black, if otherwise

   else:

       print("Black")

Prints error if input is out of range

else:

   print("Error")
