Program Specifications Write a program to calculate a course letter grade given score percentage using comprehension based on a letter grade dictionary and a mapping equation.
In this program, you are tasked to implement a function named grade_conversion that:
Takes in a dictionary containing student names and their corresponding percentage score for a course
Creates a dictionary with the student names from the passed dictionary and their corresponding letter grade using dictionary comprehension
Return the created dictionary
The function implements a conversion/mapping equation to find the letter grade corresponding to the score percentage. The mapping process will be implemented in the dictionary comprehension and is broken down to the following steps:
Identifying failing grades: a score that is below 50 is a fail, hence a score divided by 50 and floored resulting in 0 is a fail.
Mapping score to index: if the floor division does not result in a zero, you will convert the score to an integer value between 0 and 10. This is done through subtracting 50 from the score and then applying floor division by 5, for example:
score=63 is transformed as --> (63-50)//5 --> giving value 2
Letter grade mapping: the index created from the previous step is then used as a key in the following dictionary and corresponds to a letter grade
letter_grades={0:'D',1:'C-',2:'C',3:'C+',4:'B-',5:'B',6:'B+',7:'A-',8:'A',9:'A+',10:'A+'}
Steps of implementation
Define your function with dictionary parameter
Inside your function define the letter grade dictionary provided above
Use dictionary comprehension to create a dictionary using the previously stated rules (in one line)
The comprehension will fetch a pair (key and value) from the dictionary passed to it
Insert the key and the value converted to letter grade using the previously stated rules
In the main code, you will complete the missing sections based on the given comments.
Call your function
Print the returned dictionary in tabular format The output should look like this (use 28 dashes and a single tab between the student name and grade):

This is a question about the design of the spaghetti bridge.
The conditions are as follows:
1. Length 600mm or less
2. Width 50 mm or more
3.Integrated distance 500 mm
4.Weight 350g or less
Could you tell me the ideal truss bridge model and girder bridge model?
-Realistic Considerations for Spaghetti Bridge Construction
I would appreciate it if you could tell me why it is difficult to make girder bridges when making spaghetti bridges.
The ideal truss bridge model for spaghetti bridge construction within the given conditions is the **Warren truss bridge**. The Warren truss is a popular choice due to its ability to distribute loads evenly and efficiently.
It consists of diagonal members that form triangular patterns, providing strength and stability to the bridge structure. This design allows for optimal weight distribution and load-bearing capabilities while maintaining the required dimensions and weight restrictions.
On the other hand, constructing **girder bridges** using spaghetti can be challenging due to the inherent properties of spaghetti as a building material. Spaghetti is relatively weak and prone to bending or breaking under tension. Girder bridges typically require long, horizontal beams (girders) to support the load. Achieving the necessary rigidity and strength with spaghetti for such long spans can be difficult. Spaghetti's flexibility and limited tensile strength make it less suitable for long, continuous girders, as they are more likely to sag or collapse under the load.
In addition, constructing girder bridges with spaghetti may require intricate joint connections to ensure stability. Spaghetti's lack of structural integrity can make it difficult to achieve reliable connections between the girders and other bridge components. The construction process becomes more complex, and the risk of failure increases.
Considering these factors, truss bridges are generally preferred over girder bridges when using spaghetti as a construction material. Truss bridges offer a better balance between structural stability, load-bearing capacity, and the limitations of spaghetti's properties.

(a) (4 pts) Sketch the upper right quadrant for each constellation. I.e., plot the points ï in the constellation with Re[x] ≥ 0 and Im[x] ≥ 0. (b) (6 pts) Which constellation has better power efficiency? (You can answer this by computing the power efficiencies in each case, but there is an easier way. If you do decide to compute the efficiencies, it is possible to avoid large sums.)
The 25-QAM constellation has a minimum distance squared of 20, which is greater than the minimum distance squared of the 16-QAM and 9-QAM constellations. Thus, the 16-QAM and 9-QAM constellations have better power efficiency than the 25-QAM constellation.
Part A) Here are the sketches of upper right quadrant for each constellation, with the points in the constellation with Re[x] ≥ 0 and Im[x] ≥ 0. 16-QAM25-QAM9-QAM25-Point constellationPart B) Power efficiency refers to how efficiently a particular modulation scheme uses power. The power efficiency in a QAM constellation is defined as the minimum distance squared between any two points in the constellation. The minimum distance squared is inversely proportional to the power efficiency. The minimum distance squared for the standard 25-QAM constellation is `2d^2`, where `d` is the distance between two adjacent points in the constellation. The distance between the adjacent points in a 25-QAM constellation is `2*sqrt(10)`. Thus, `d
= square root(10)`. So, the minimum distance squared is `2(10)
= 20`.The minimum distance squared for the 16-QAM constellation is `2(2d^2)
= 8d^2`. Thus, the distance between adjacent points is `2d
= 2*square root(2)`. Thus, the minimum distance squared is `8(2)
= 16`.The minimum distance squared for the 9-QAM constellation is `2(2d^2)
= 8d^2`. Thus, the distance between adjacent points is `2d
= 2*sqrt(2)`. Thus, the minimum distance squared is `8(2)
= 16`.Therefore, the 16-QAM constellation and the 9-QAM constellation have the same minimum distance squared and thus have the same power efficiency. The 25-QAM constellation has a minimum distance squared of 20, which is greater than the minimum distance squared of the 16-QAM and 9-QAM constellations. Thus, the 16-QAM and 9-QAM constellations have better power efficiency than the 25-QAM constellation.

The partial fractions for the given equations are as follows:
2s²2s+6 = (1/2) (1/s) - (1/2) (1/(s+3))2 (S-1)(s² +3s+2)
= 1/(s-1) - 1/(s+2) + 1/(s+1)2s² + s - 2
= 2(s + 1)(s - 1/2)2 s² (s+1) 3s-1
= 2/s + 1/(s+1) - 2(s-1)
Partial fraction is the representation of a complex rational function as the sum of simple rational expressions. A partial fraction can be divided into three categories, namely: proper, improper and mixed.
In the first problem, we have: 2s²2s+6
Our first step is to factor the denominator as shown below: 2(s² + s + 3)
Using partial fractions, we write: 2s²2s+6 = A/s + B/(s+3)
Let's find A and B: 2s²2s+6 = A(s+3) + B(s)2s²2s+6 = As + 3A + Bs
Comparing the coefficients of s², s and the constants, we get:A = 1/2B = -1/2
Therefore,2s²2s+6 = (1/2) (1/s) - (1/2) (1/(s+3))
Next, we consider:2 (S-1)(s² +3s+2)
Factorize the denominator as shown below:
2(s-1)(s+2)(s+1)2 (S-1)(s² +3s+2) = A/(s-1) + B/(s+2) + C/(s+1)
Now, we solve for A, B and C as follows:
2 (S-1)(s² +3s+2) = A(s+2)(s+1) + B(s-1)(s+1) + C(s-1)(s+2)
When s = 1, we have:2 (1-1)(1² + 3(1) + 2) = A(1+2)(1+1)
Therefore, A = 1
When s = -2, we have: 2 (-2-1)(-2² + 3(-2) + 2) = B(-2-1)(-2+1)
Therefore, B = -1
When s = -1, we have: 2 (-1-1)(-1² + 3(-1) + 2) = C(-1-1)(-1+2)
Therefore, C = 1
So, 2 (S-1)(s² +3s+2) = 1/(s-1) - 1/(s+2) + 1/(s+1)
In the third problem, we have: 2s² + s - 2
This is a quadratic equation. To factorize it, we find its roots using the quadratic formula, which is given as:-
b ± √(b² - 4ac)2a
Hence, we have:
s1,2 = (-b ± √(b² - 4ac))/2a
On substituting the coefficients, we have:
s1,2 = (-1 ± √(1² - 4(2)(-2)))/2(2)s1 = -1s2 = 1/2
We factorize the equation as shown below:
2s² + s - 2 = 2(s + 1)(s - 1/2)
Finally, we have:2 s² (s+1) 3s-1
This problem can be solved by using partial fractions.
We write the equation as:
2 s² (s+1) 3s-1 = A/s + B/(s+1) + C(s-1)
Solving for A, B and C, we have:
A = 2C = -2B = 1
Therefore,2 s² (s+1) 3s-1 = 2/s + 1/(s+1) - 2(s-1)
Therefore, the partial fractions for the given equations are as follows:
2s²2s+6 = (1/2) (1/s) - (1/2) (1/(s+3))2 (S-1)(s² +3s+2)
= 1/(s-1) - 1/(s+2) + 1/(s+1)2s² + s - 2
= 2(s + 1)(s - 1/2)2 s² (s+1) 3s-1
= 2/s + 1/(s+1) - 2(s-1)

Write Python code for the following: a) Car Class: Write a class named Car that has the following data attributes: _year_model for the car's year model) __make (for the make of the car) -speed (for the car's current speed) The Car class should have an __init_method that accepts the car's year model and make as arguments. These values should be assigned to the object's __year_model and__make data attributes. It should also assign 0 to the speed data attribute. The class should also have the following methods: Accelerate: The accelerate method should add 5 to the speed data attribute each time it is called. • Brake: The brake method should subtract 5 from the speed data attribute each time it is called get_speed: The get_speed method should return the current speed. Next, design a program that creates a Car object then calls the accelerate method five times. After each call to the accelerate method, get the current speed of the car and display it. Then call the brake method five times. After each call to the brake method, get the current speed of the car and display it
The Python code defines a Car class with attributes and methods for acceleration and braking. It creates a car object, accelerates it five times, displays the current speed after each acceleration, then applies brakes five times, displaying the current speed after each brake.
Following is the python code for Car Class that has _year_model, __make, and -speed data attributes:
class Car:
def __init__(self, year_model, make):
self._year_model = year_model
self.__make = make
self.__speed = 0
def Accelerate(self):
self.__speed += 5
def Brake(self):
self.__speed -= 5
def get_speed(self):
return self.__speed#
car1 = Car(2022, "Tesla")
for i in range(5):
car1.Accelerate()
print(f'Car\'s current speed is: {car1.get_speed()}')
for i in range(5):
car1.Brake()
print(f'Car\'s current speed is: {car1.get_speed()}')
The above program creates a car object, accelerates five times, displays the current speed after each acceleration, then applies brakes five times, displaying the current speed after each brake application.

The Information Sequence Is A Sequence Of Independent Equiprobable Binary Symbols Taking Values Of +1 Or -1. This Data Sequence Modulates The Basic Pulse G(T). The Modulated {A} Is Signal X(T) Is As Follows: Ost≤27 X(T)=[Ang(T-N7) Otherwise I) Find The Power Spectral Density Of X(T). Ii) If We Use A Precoding Of The Form Bn-An-An-1,Determine The Power
i) To find the power spectral density of x(t), we need to follow the below steps:
Given x(t) = Ao g (t) = Ao (t + 4) (1 + δ (t)) + Ao (t - 4) (1 + δ (t))
Given that, A0 = 1 & G (f) = sin2πfT/T(πfT)/(πfT) = (sinπfT)/(πfT) (In rectangular form)
From this, we can obtain the power spectral density of x(t)P(f) = [A0/2G(f)]2
Thus, P(f) = [1/(2*(sinπfT)/(πfT))]2
On simplification, P(f) = [(πfT)/2]2Thus, the power spectral density of x(t) is P(f) = (πfT)2/4.
ii) If we use precoding of the form bn-an-an-1, the power is given by:
P = [(Ao)2 + (Bo)2 + (Co)2 + (Do)2]P = [A02 + (A0 - A1)2 + (-A1)2 + (-A1)2]P = 3 (A0)2 + 2 (A1)2
We know A0 = 1So, P = 3 + 2 (A1)2
Hence, we got the power using precoding.

Suppose that strl, str2, and str3 are string variables, and strl = "English", str2 = "Computer Science", and str3= "Programming". Evaluate the following expressions. a. strl> str2 b. strl = "english" C. str3= "Chemistry"
strl > str2, where 'E' has a higher ASCII value than 'C', the expression strl > str2 evaluates to true. strl = "english" , so here the expression strl = "english" evaluates to false. str3= "Chemistry" evaluates as false.
strl > str2: The expression "English" > "Computer Science" is evaluated based on lexicographic order. In lexicographic order, each character is compared based on its ASCII value. Since 'E' has a higher ASCII value than 'C', the expression strl > str2 evaluates to true. strl = "english": The expression compares the string variable strl with the string literal "english". The comparison is case-sensitive, so "English" and "english" are considered different. Therefore, the expression strl = "english" evaluates to false. str3 = "Chemistry": The expression compares the string variable str3 with the string literal "Chemistry". Since the value of str3 is "Programming" and not "Chemistry", the expression str3 = "Chemistry" evaluates to false.

What is the effect of multiplying by (-1)x+y the spatial-domain image before applying the 2-D DFT? Explain briefly.
Multiplying by (-1)^(x+y) the spatial-domain image before applying the 2-D DFT results in the image being shifted by half a pixel both horizontally and vertically. This is known as the centering operation, and it has several benefits.
Firstly, centering the image prior to applying the DFT ensures that the DC component of the frequency spectrum (i.e., the component with zero frequency) is located at the center of the transformed image, rather than at one of the corners.
This helps to reduce the occurrence of aliasing artifacts in the transformed image .
In summary, multiplying by (-1)^(x+y) before applying the 2-D DFT centers the image, ensuring that the DC component of the frequency spectrum is located at the center of the transformed image and reducing the effects of aliasing.

The outermost loop is executed n times, the second loop is executed n times for each execution of the outermost loop. Hence, the second loop is executed n*n = n² times.
Similarly, the innermost loop is executed n times for each execution of the second loop, giving a total of n*n*n = n³ iterations of the innermost loop. Each iteration of the innermost loop involves one addition and one modulus operation. Therefore, the total number of operations can be calculated as n x n² x (2 x 1) = 2n³.
Thus, the big O running time of the myMethod() method is O(n³).

A causal linear invariant system is represented by the following difference equation M[n]-[n-1]+[-2] = x[n] Find the transfer function of the system; If the system input is x[n] = (u[r]. find the response of the system y[r].
The response of the system y[n] is given asy[n] = δ[n] - (1 / 2^n) u[n] - δ[n - 1] + (1 / 2^(n - 1)) u[n - 1]
From the question above, difference equation isM[n] - M[n - 1] + M[n - 2] = x[n]
The transfer function H(z) of a system is defined as the ratio of the Z-transforms of the output Y(z) to the input X(z) when all initial conditions are zero.
Thus, the transfer function H(z) of a system is given as
H(z) = Y(z) / X(z)
The Z-transform of the input signal x[n] isX(z) = 1 / (1 - z^(-1))
The Z-transform of the output signal y[n] isY(z) = H(z) X(z)
Thus, the Z-transform of the difference equation is given asY(z) = H(z) X(z) = H(z) / (1 - z^(-1))
Therefore, the transfer function H(z) of the system can be obtained as follows:
M(z) - z^(-1) M(z) + z^(-2) M(z) = X(z)H(z) = Y(z) / X(z) = M(z) / [1 - z^(-1) + z^(-2)]
Substituting x[n] = (u[n]) in difference equationM[n] - M[n - 1] + M[n - 2] = x[n]M[n] - M[n - 1] + M[n - 2] = u[n]
The input signal x[n] = (u[n]) can also be written asx[n] = u[n] - u[n - 1]
Using Z-transform of x[n],X(z) = 1 / (1 - z^(-1)) - z^(-1) / (1 - z^(-1))
Taking Z-transform of the difference equation,M(z) - z^(-1) M(z) + z^(-2) M(z) = X(z)M(z) (1 - z^(-1) + z^(-2)) = X(z) (1)M(z) = X(z) / (1 - z^(-1) + z^(-2))M(z) = [1 / (1 - z^(-1) + z^(-2))] / [1 / (1 - z^(-1))]M(z) = (1 - z^(-1)) / (1 - 2z^(-1) + z^(-2))
Thus, the transfer function of the system isH(z) = (1 - z^(-1)) / (1 - 2z^(-1) + z^(-2))
Substituting the value of x[n], x[n] = (u[n]), in the difference equation,M[n] - M[n - 1] + M[n - 2] = u[n]
Therefore, the difference equation of the system can be written asM[n] - M[n - 1] + M[n - 2] = u[n]M[n] = M[n - 1] - M[n - 2] + u[n]
The output signal y[n] can be obtained by convolving the input signal x[n] with impulse response h[n]y[n] = x[n] * h[n]
Where, h[n] is the inverse Z-transform of the transfer function H(z)
.h[n] = (1 / (1 - z^(-1))) - (1 / (1 - 2z^(-1) + z^(-2)))
Taking inverse Z-transform of H(z),h[n] = δ[n] - (1 / 2^n) u[n]
Thus, the output signal y[n] can be written asy[n] = x[n] * h[n]y[n] = (u[n] - u[n - 1]) * h[n]y[n] = δ[n] - (1 / 2^n) u[n] - δ[n - 1] + (1 / 2^(n - 1)) u[n - 1]

Suppose a machine has two caches, an Ll cache and an L2 cache. Assume the following characteristics of cache performance: The processor is able to execute an instruction every cycle, assuming there is no delay fetching the instruction or fetching the data used by the instruction. An L1 cache hit provides the requested instruction or data immediately to the processor (i.e. there is no delay). An L2 cache hit incurs a penalty (delay) of 10 cycles. . . Fetching the requested instruction or data from memory – which happens when there is an L2 miss – incurs a penalty of 100 cycles. That is, the total delay is 100 cycles on an L2 miss, don't add the 10-cycle delay above. The L1 miss rate for both instructions and data is 3%. That is, 97% of instruction and data fetches result in an L1 cache it. The L2 miss rate for instructions is 1% and for data is 2%. That is, of those instruction fetches that result in an Ll cache miss, 99% of them will result in an L2 cache hit. Similarly, of those data fetches that result in an Ll cache miss, 98% of them will result in an L2 cache hit. 30% of instructions require data to be fetched (the other 70% don't). Given a program that executes I instructions, how many cycles would the program take to execute, under the above assumptions? Be sure to show your work. b. Suppose you are manufacturer of the above machine and, in the next release, you have the option of increasing the size of the Ll cache so that the Ll miss rate is reduced by 50% for both data and instructions or increasing the size of the L2 cache so that the L2 miss rate is reduced by 50% for both data and instructions. If your only goal was to make the above program faster, which option would you choose? Show your work. a.
Total number of cycles required to execute the program under option 2= 0.10639I + 1.2917I = 1.39809I. Therefore, we would choose option 2 which is to increase the size of the L2 cache so that the L2 miss rate is reduced
A given program that executes I instructions, under the given assumptions, the number of cycles it would take to execute it are; Number of instructions that require data to be fetched = 0.3I;Number of instructions that do not require data to be fetched = 0.7I;L1 miss rate for both data and instructions = 3%;L2 miss rate for instructions is 1% and for data is 2%;Number of instruction fetches that result in an L1 cache miss = 0.03 x I = 0.03I;Number of instruction fetches that result in an L1 cache hit = 0.97 x I = 0.97I;Number of data fetches that result in an L1 cache miss = 0.03 x 0.3I = 0.009I
Number of data fetches that result in an L1 cache hit = 0.97 x 0.3I = 0.291I;Number of instruction fetches that result in an L1 miss and an L2 cache hit = 0.99 x 0.03I = 0.0297I;Number of data fetches that result in an L1 miss and an L2 cache hit = 0.98 x 0.009I = 0.00882I;Therefore, the total number of cycles required to execute the program is: Number of cycles required for instructions that require data to be fetched = (0.03I x 10) + (0.009I x 110) + (0.0297I x 10) = 0.468I.

A continuous rectification column is to be designed to seperate a mixture of 33.45 % (w/w) methanol and water into an overhead product containing 95.5% (w/w) methanol using a reflux ratio 1.3 times the minimum value. A bottom product contains 3.25 % (w/w) water. The distilate product rate is 1745 kg/h. The feed is a mixture of two-thirds vapor and one third liquid. Methanol and water can be considered as ideal system with a relative volatility of about 3.91. Design a rectification column using parameters above.
A rectification column with approximately 6 theoretical stages is required to achieve the desired separation of methanol and water using the given specifications and design parameters.
To design the rectification column, we need to determine the number of theoretical stages required and the reflux ratio based on the given specifications. Here's the design process:
1. Determine the minimum reflux ratio (Rmin):
The minimum reflux ratio can be calculated using the Fenske equation:
Rmin = (L/D)min = (V/F)min = α / (α - 1)
where α is the relative volatility of the key component, which is 3.91 in this case.
Rmin = 3.91 / (3.91 - 1) = 1.955
2. Calculate the actual reflux ratio (R):
R = Rmin * 1.3 = 1.955 * 1.3 = 2.5395
3. Determine the key component compositions:
Overhead Product (Distillate): 95.5% methanol, 4.5% water
Bottom Product: 3.25% methanol, 96.75% water
4. Calculate the key component flow rates:
Distillate flow rate (D): 1745 kg/h * 0.955 = 1666.975 kg/h (methanol)
Bottom flow rate (B): 1745 kg/h * 0.0325 = 56.70625 kg/h (water)
5. Determine the feed flow rate (F):
The feed consists of two-thirds vapor and one-third liquid, so:
F = D / (α - 1) + B / (1 - α) = 1666.975 / (3.91 - 1) + 56.70625 / (1 - 3.91)
F = 958.3125 kg/h (total feed)
6. Calculate the reflux flow rate (L):
L = R * D = 2.5395 * 1666.975 = 4232.784 kg/h
7. Determine the key component compositions at various stages:
At the top stage (overhead product):
Xmethanol = 0.955 (given)
Xwater = 1 - Xmethanol = 1 - 0.955 = 0.045
At the bottom stage (bottom product):
Xmethanol = 0.0325 (given)
Xwater = 1 - Xmethanol = 1 - 0.0325 = 0.9675
8. Determine the number of theoretical stages (N):
N = log((Xbottom - Xtop) / (Xtop - Xfeed)) / log(R)
N = log((0.9675 - 0.045) / (0.045 - 0.0333)) / log(2.5395)
N ≈ 5.83
Since the number of theoretical stages should be an integer value, we round up to the next whole number:
N = 6
Therefore, a rectification column with approximately 6 theoretical stages is required to achieve the desired separation of methanol and water using the given specifications and design parameters.

W k=⎩⎨⎧2/(Kπ)02k Is Odd K Is Even And K=0k=0Let W(T) be the input to an LTI system with a frequency response H(Ω)=ΩTsin(ΩT) To find the Fourier Transform (FT) of the signal, we use the formula :FT={2πW k(e^(-jωk))}The signal is even and so we can simplify the Fourier Transform further :FT={2πW0/2 + Σ (2πW k/2) (cos(kω))}From the given function, we can get the value of Wk. For k=0, W0 = 2/0π = ∞.
Hence, we can rewrite the function as: W k=⎩⎨⎧2/(Kπ)02k Is Odd K Is Even And K=0k=0, k≠0Wk=0, k=0Therefore,FT={2πW0/2 + Σ (2πW k/2) (cos(kω))} can be rewritten as: FT={π + Σ (2πW k/2) (cos(kω))}For the given signal, W(T), we can write its Fourier Transform as: W(Ω) = {2πW0/2 + Σ (2πW k/2) (δ(Ω - kω) + δ(Ω + kω)))}We can get the values of W0 and W k for the given signal, W(T).
Thus ,FT of W(T) = {π + Σ (2πW k/2) (cos(kω))} * H(Ω) = {π + Σ (2πW k/2) (cos(kω))} * ΩTsin(ΩT)We have the Fourier Transform of the given signal, W(T).

A zenith angle of 101°33'40" is equivalent to a vertical angle of: O +11°33'40 -11°33'40" O +78 26 20 O-78°26'20" O258°26'20"
A zenith angle of 101°33'40" is equivalent to a vertical angle of approximately -11°33'40".
To convert a zenith angle of 101°33'40" to a vertical angle, we need to subtract it from 90 degrees. The vertical angle represents the angle between the line of sight and the horizontal plane.
Given:
Zenith angle = 101°33'40"
To convert it to a vertical angle:
Vertical angle = 90° - Zenith angle
Vertical angle = 90° - 101°33'40"
To subtract the values, we need to perform the conversion of minutes and seconds to decimal form.
1 minute (') = 1/60 degree
1 second (") = 1/60 minute = 1/3600 degree
101°33'40" can be written as:
101 degrees + 33/60 degrees + 40/3600 degrees
Vertical angle = 90° - (101° + 33/60° + 40/3600°)
Performing the calculation:
Vertical angle = 90° - (101° + 0.55° + 0.0111°)
Vertical angle ≈ -11°33'40"
Therefore, a zenith angle of 101°33'40" is equivalent to a vertical angle of approximately -11°33'40".

The value placed in the page table to redirect linear address 20000000H to physical address 30000000H is B, 30000000H.
What is paging?Paging is a memory management method that uses a page table to map logical addresses to physical addresses. The logical address space of a program is divided into pages of a fixed size, and the physical address space of the computer is also divided into frames of the same size.
A logical address is divided into two parts: the page number and the offset within the page. A page table is used to map the page number to a physical frame number and an offset within that frame.
Suppose we have a linear address of 20000000H that needs to be redirected to a physical address of 30000000H. The page size is assumed to be 4KB. In this scenario, the page number would be 20000000H divided by 4096, which is equal to 4D91H.
The value placed in the page table to redirect linear address 20000000H to physical address 30000000H would be the frame number of the physical page, which is equal to 30000000H divided by 4096, which is equal to 7380H.
So, the value placed in the page table to redirect linear address 20000000H to physical address 30000000H is B, 30000000H.
