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

OR

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

i hope it will help you!

Fix thos code:Error using spm_check_installation>check_basic (line 93) You do not appear to have the function search path set

grandymaker [24]

Answer:

addpath C:\Program Files\MATLAB\ToolBoxes-20181106T221851Z-001\ToolBoxes\SPM\spm12

savepath

Explanation:

The error clearly indicates that the SPM is missing and is not properly installed. In order to correct this, the following commands are required to be run in the command line of the MATLAB.

These commands will do following.

The first command is the addpath, this will add the path of the toolboxes in the working directory path of the MATLAB

addpath C:\Program Files\MATLAB\ToolBoxes-20181106T221851Z-001\ToolBoxes\SPM\spm12

The second command is the savepath, this will save the additional added path of the working directory for future use.

savepath

Selecting missing puppies 1 # Select the dogs where Age is greater than 2 2 greater_than_2 = mpr [mpr. Age > 2] 3 print(great

anygoal [31]

Answer:

# the dog dataframe has been loaded as mpr

# select the dogs where Age is greater than 2

greater_than_2 = mpr [mpr. age > 2]

print(greater_than_2)

# select the dogs whose status is equal to 'still missing'

still_missing = mpr[mpr. status == 'Still Missing']

print(still_missing)

# select all dogs whose dog breed is not equal to Poodle

not_poodle = mpr [mpr.breed != 'Poodle']

print(not_poodle)

Explanation:

The pandas dataframe is a tabular data structure that holds data in rows and columns like a spreadsheet. It is used for statistical data analysis and visualization.

The three program statements above use python conditional statements and operators to retrieve rows matching a given value or condition.
