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

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!

Universal Containers has implemented a strict software architecture for their custom Apex code. One of the requirements is that

maxonik [38]

Answer:

The required coding for the architect to meet these requirement has been described below.

Explanation:

The following ways will help the architecture to meet the requirement.

Create a reusable SOQLQueries class; specify “With Sharing” on the methods that require user context and “Without Sharing” on the methods requiring system context.

Create a SystemSOQLQueries class and a UserSOQLQueries class; set the “With Sharing” keyword on the UserSOQLQueries class and “Without Sharing” on the SystemSOQLQueries class.

Assuming outFile is a file stream object and number is a variable, which statement writes the contents of number to the file ass

professor190 [17]

Answer:

Its outfile<<number.

However, before this we need to write

outfile.open("xyz.txt", ios;;out)

outfile<<number

And this code will do what is required in the question. This is going to write the number's content to the xyz.txt file which is the file associated with the outfile.

And remember this is in C++. And C++ is a imperative oriented programming language. Undoubtedly, Python and R are fully object oriented programming languages.

Explanation:

The answer is self explanatory.

How do you fix this windows 7 screen

tensa zangetsu [6.8K]

Try restarting it. If you can’t restart because the screen is frozen maybe just turn it off and back on. If you already tried restarting and it still didn’t fix the problem, just give it some time. The computer will reset itself eventually which should fix the problem.
