A computer’s memory is composed of 8K words of 32 bits each. How many bits are required for memory addressing if the smallest ad

victus00 [196]

Answer:

The minimum number of bits necessary to address 8K words is 13.

Explanation:

You have the number of words to address that is 8000 words, a word is the smallest addressable memory unit.

8000 words can be addressed with $2^{n}$ units. Now you have to find the value of n that approximates to the number of words.

$2^2=4\\2^4=16\\2^7=128\\2^{10}=1024\\2^{12}=4096\\2^{13}=8192$

So you can see that 13 bits are needed to address 8K words.

11.19 LAB: Max magnitude Write a function max_magnitude() with two integer input parameters that returns the largest magnitude v

AlekseyPX

Answer:

# the user is prompt to enter first value

user_val1 = int(input("Enter first value: "))

# the user is prompt to enter second value

user_val2 = int(input("Enter second value: "))

# max_magnitude function is defined

# it takes two parameters

def max_magnitude(user_val1, user_val2):

# if statement to compare the values

# it compare the absolute value of each

if(abs(user_val2) > abs(user_val1)):

return user_val2

elif (abs(user_val1) > abs(user_val2)):

return user_val1

# max_magnitude is called with the

# inputted value as parameter

print(max_magnitude(user_val1, user_val2))

Explanation:

The code is written in Python and well commented. A sample image of program output is attached.

A company is performing an analysis on the computers at its main office. The computers are spaced along a single row. The analys

harina [27]

Answer:

array = input("Enter the list of computer memory: ").split(',')

int_arr = [int(x) for x in array]

segment = int(input("Enter the length of segment to analyze: "))

list_len = len(int_arr)

segList = []

mini = []

for x,i in enumerate(int_arr):

seg = int_arr[i-1:segment+i-1]

if len(seg) == segment:

segList.append(seg)

for x in segList:

mini.append(min(x))

result = mini.index(min(mini))

print("Segment with the minimum memory is: ",segList[result])

Explanation:

The python program prints out the segment after analysis, with the smallest disk memory space. The code gets the array of computer rows from the user input and segments the array with the number of segment input, then the minimum is compared for all segments in the network.
