Answer: To be useful for most household applications, DC voltage is passed through a step-down transformer.

Explanation: Voltage coming through AC or DC outlets is typically far too high for most household appliances to handle, so the current is passed through a step-down transformer to reduce the voltage to a usable level.

Answers of blanks:

1. 3 bits

2. 20 bits

3. 64 MB

4. 16 MB

5. 64 KB

6. 64 MB

Explanation:

Following is the solution for question step-by-step:

Part 1:

No. of Tag bits = No. of bits to represent

Tag bits = Main memory - cache size bits -------- (A)

Given:

Main memory = 128 KB = $2^7 * 2^{10} = 2^{17}$

Cache Memory = 16 KB = $2^4 * 2^{10}= 2^{14}$

Putting values in A:

Tag bits = 17 - 14 = 3 bits

Part 2:

Tag bits = Main memory - cache size bits -------- (A)

Given:

Main memory = 32 GB = $2^5 * 2^{30} = 2^{35}$

Cache Memory = 16 KB = $2^5 * 2^{10}= 2^{15}$

Putting values in A:

Tag bits = 35 - 15 = 20 bits

Part 3:

Given:

Tag bits = 7

Cache Memory = 512 KB = $2^9 * 2^{10} = 2^{19}$

So from equation A

7 = Main Memory size - 19

Main Memory = 7 + 19

Main memory = 26

Main Memory = $2^6 * 2^{20} = 64 MB$

Part 4:

Given that:

Main Memory Size = $2^4 * 2^{30} = 2^{34}$

Tag bits = 10

Cache Memory Bits = 34 - 10 = 24

Cache Memory Size = $2^4 * 2^{20} = 16 MB$

Part 5:

Given that:

Main Memory Size = 64 MB = $2^6 * 2^{20}$

Tag bits = 10

Cache Memory Bits = 26 - 10 = 16

Cache Memory Size = $2^{16} = 2^6 * 2^{10} = 64 KB$

Part 6:

Cache Memory = 512 KB = $2^9 * 2^{10} = 2^{19}$

Tag Bits = 7

Main Memory Bits = 19 + 7 = 26

Main Memory size = $2^{26} = 2^6 * 2^20 = 64 MB$

Modify the program you wrote for Chapter 6 Exercise 6 so it handles the following

Basile [38]

Answer:

#try except

try:

#opening the file

read_file = open('numbers.txt', 'r')

#Store the numbers in the variable file_numbers.

file_numbers = read_file.read()

#close the file

read_file.close()

#Split the number of files in list_values.

list_values = file_numbers.split()

#how many numbers are there

list_length = len(list_values)

try:

#loop it up

for i in range(list_length):

list_values[i] = float(list_values[i])

#Add up all the numbers, put into list_sum

List_sum = sum(list_values)

#heres how we average it

Average_value = (List_sum)/list_length

#print

print(Average_value)

except ValueError:

print( "File must have only numbers. Try again." )

#handles IOError exceptions

except IOError:

#Display statement

print("Trouble opening file. Try again.")

Explanation:

The python program uses the try-except exception handling method to catch errors in the code. The IOError is used for catching input and output errors in the program like file handling while the ValueError keyword in the except statement is used to catch data type errors from a return statement, calculation or user input.

Determining Correct Date Function What function text would you use to put today's date and time in a cell? 0 =TODAYO =NOWO O NOW

Murrr4er [49]

Current date formula:

=TODAY()

Current time formula:

=NOW()

As you can see, the =TODAY() formula only includes the day, month and year. The =NOW() function displays more information, showing the day, month, year, hour and minutes (using a 24-hour clock)
