You have a large text file of people. Each person is represented by one line in the text file. The line starts with their ID number and after that, has the person's name. The lines are sorted by ID number in ascending order. There are n lines in this file. You write a search function that returns the name of a person whose ID number is given The simplest way to do that would be to program a loop that goes through each line and compares the ID number in the line against the given ID number. If there is a match, then it returns the name in that line. This is very inefficient, because the worst-case scenario is that this program needs to go through almost everyone the person we are looking for could be last. using the fact that he tli s sored wil greany speed up the processbus to use a birarysearch alkrhm We go to the middle line of the file first and compare the ID found there (P) to the given ID (Q). (f the number of lines is even, we go above or below the arithmetic middle.) if P=Q then our algorithm terminates . we have found the person we are looking for. If P is less than Q, that means that the person we are looking for is in the second half of the file. We now repeat our algorithm on the second half of the file. If P is greater than Q, that means that the person we are looking for is in the first half of the file. We now repeat our algorithm on the first half of the file.

Required:

Assume a 64KB cache with four-word block size (a word is 4 bytes) and a 32-bit address. If a block has 28 tag bits, what is the type of this cache

Answers

Answer:

Fully associative

Explanation:

Fully associative cache is a type of cache in which after retrieving the data from memory, it subsequently allows data to be deposited in the available but unused cache block. This is to ensure that the storage of cache is done without forcing each memory address into one specific block.

Given the following

address = 32 bits,

tag = 28 bits, as a block is 4 words that are, 4x4 bytes,

offset = 4 bits, which equates to index = 0 bits.

Hence, it can be concluded that the type of cache is FULLY ASSOCIATIVE.

b. QAM is a modulation technique in which both carrier amplitude and phase angle changes represent logical data
c. with QAM, two carrier waves of the same frequency, but separated by π/2 radians, are used to represent logical data
d. all statements are correct

Answer:

The answer is "Option d".

Explanation:

The electronic firmware synchronization was its method where even the series of bytes is amplified even before the transmission process into to the sound waves and, thus, and in conceptual "1s" and "0s" represented by large font, wavelengths, or switching frequency.

QAM utilizes both magnitudes of the transporter and adjustments in the phase shift. Rational data is represented by [tex]\frac{\pi}{2}[/tex] cartesian coordinates for both the carries waves of the same wavelengths and represents the result in total.

The Beaufort Wind Scale is used to characterize the strength of winds. The scale uses integer values and goes from a force of 0, which is no wind, up to 12, which is a hurricane. The following script first generates a random force value. Then, it prints a message regarding what type of wind that force represents, using a switch statement. You are to rewrite this switch statement as one nested 150 CHAPTER 4: Selection Statements if-else statement that accomplishes exactly the same thing. You may use else and/or elseif clauses.

ranforce = randi([0, 12]); switch ranforce case 0 disp('There is no wind') case {1,2,3,4,5,6} disp('There is a breeze') case {7,8,9} disp('This is a gale') case {10,11} disp('It is a storm') case 12 disp('Hello, Hurricane!') end

Answers

Answer:

ranforce = randi([0, 12]);

if (ranforce == 0)

     disp('There is no wind')

else  if(ranforce>0 && ranforce <7)

     disp('There is a breeze')

else  if(ranforce>6 && ranforce <10)

     disp('This is a gale')

else  if(ranforce>9 && ranforce <12)

     disp('It is a storm')

else  if(ranforce==12)

     disp('Hello, Hurricane!')

end

Explanation:

Replace all switch case statements with if and else if statements.

An instance is:

case {7,8,9}

The trigonometry book says: sin^2(t) + cos^2(t) = 1 Write a Python program that verifies the formula with the help of the Python Math module. Note that the trigonometric functions in the module act on the angles in radians. Your program should perform the following steps 3 times: 1. Pick a random number between 0 and 180 degrees representing an angle in degrees, say Dangle 2. Convert the angle from degrees to radians, say Rangle 3. Use the Math module to find and print the values of sin(Rangle) and cos(Rangle), and 4. Compute and print the value of the above expression: sin^2(Rangle) + cos^2(Rangle). You can then visually verify if the result printed is 1 (or close to it).

Answers

Answer:

If you open your python-3 console and execute the following .py code you will have the following output. (Inputing 20 e.g)

Write the angles in degrees: 20

radian angles is:  0.3490658503988659

cosene( 0.3490658503988659 ) =  0.9396926207859084

sine( 0.3490658503988659 ) =  0.3420201433256687

sin^2( 0.3490658503988659 ) + cos^2( 0.3490658503988659 ) =  1.0

Explanation:

Code

import math

for i in range(1,4):

   angle = int(input('Write the angles in degrees: '))

   #mat library better works with radians

   angle_radians = (angle*math.pi)/180

   #print output

   print('radian angles is: ',angle_radians)

   print('cosene(',angle_radians,') = ',math.cos(angle_radians))

   print('sine(',angle_radians,') = ',math.sin(angle_radians))

   res = (math.sin(angle_radians))**2 + (math.cos(angle_radians))**2

   print('sin^2(',angle_radians,') + cos^2(',angle_radians,') = ',res)

Write a program with a car's miles/gallon and gas dollars/gallon (both floats) as input, and output the gas cost for 10 miles, 50 miles, and 400 miles. Ex: If the input is 20.0 3.1599, the output is: 1.57995 7.89975 63.198 Note: Small expression differences can yield small floating-point output differences due to computer rounding. Ex: (a + b)/3.0 is the same as a/3.0 + b/3.0 but output may differ slightly. Because our system tests programs by comparing output, please obey the following when writing your expression for this problem. First use the dollars/gallon and miles/gallon values to calculate the dollars/mile. Then use the dollars/mile value to determine the cost per 10, 50, and 400 miles. Note: Real per-mile cost would also include maintenance and depreciation.

Answers

Answer:

The Following are the code to this question:

def cost(miles, milesPerGallon, dollarsPerGallon):##defining a method cost that accepts three parameter

   return miles / milesPerGallon * dollarsPerGallon# calculate cost and return it value  

milesPerGallon = float(input('Enter miles/Gallon value: '))#defining variable milesPerGallon for user input  

dollarsPerGallon = float(input('Enter dollars/ Gallon value: '))#defining variable dollarsPerGallon for user input

print('{:.5f}'.format(cost(10, milesPerGallon, dollarsPerGallon)))#call method and print its value

print('{:.5f}'.format(cost(50, milesPerGallon, dollarsPerGallon)))#call method and print its value

print('{:.3f}'.format(cost(400, milesPerGallon, dollarsPerGallon)))#call method and print its value

Output:

Enter miles/Gallon value: 20.0

Enter dollars/ Gallon value: 3.1599

1.57995

7.89975

63.198

Explanation:

In the above-given code, a method "cost" is defined, that accepts three value "miles, milesPerGallon, and dollarsPerGallon" in its parameter, and use the return keyword for calculating and return its value.

In the next step, two variable "milesPerGallon, and dollarsPerGallon" is declared, that use the input method with float keyword for input floating-point value.

After input value, it uses a print method with different miles values, which are "10,50, and 400", and input value to pass in cost method to call and print its return value.

W. Edwards Deming used the phrase "continuous improvement" to refer to general processes of improvement and to embrace "discontinuous" improvements, or many diverse ways addressing various topics.

A subset of continuous improvement, with a more narrow focus on linear, incremental change inside an already-existing process, is continuous improvement.

Some practitioners also believe that statistical process control techniques are more closely related to continuous improvement. Constant improvement, often known as continuous improvement, is the continued enhancement of goods, services, or procedures through both small-scale and significant advancements.
