Fill in the missing fields based upon the properties of a direct-mapped cache. Click on "Select" to access the list of possible answers Main Memory Size Cache Size Block Size Number of Tag Bits 3 1) 16 KiB 128 KiB 256 B 20 2) 32 GiB 32 KiB 1 KiB 3) 64 MiB 512 KiB 1 KiB Select] 4 KiB 4) 16 GiB 10 Select ] Select ] 5) 10 64 MiB [ Select ] 6) Select] 512 KiB 7

For convenience, the table form of the question is attached in the image below.

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:

<u>Part 1:</u>

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

<u>Part 2:</u>

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

<u>Part 3:</u>

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

<u>Part 4:</u>

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

<u>Part 5:</u>

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

<u>Part 6:</u>

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!

Why do attackers tend to target public or private Wi-fi networks?
Anika [276]

Answer:

The answer to this question is given below in this explanation section.

Explanation:

A free WiFi connection in a public space can seem like a lifesaver when you are on the go.But if you decide to use public WiFi just be aware that you could be making yourself an easy target for hackers and putting your information and more at risk.

one of the dangers of using a public WiFi network is that data over this type of open  connection is often encrypted and  unsecured ,leaving you vulnerable to a man in the middle attack.It when a cyber criminal exploits a security  flaw in the network to intercept data

  • Avoid connecting to public WiFi connection. i if you must use a public WiFi hotpots also use a virtual privater network to secure your connection.
  • Do not  log in to password protected websites that contains sensitive information when using a public WiFi connection for example banking and social networking sites or even email.
  • Keep your software patched and up to date and all your devices even your mobiles ones to avoid any potential infection by viruses or malware if you do use unsecured public WiFi.

When creating a spreadsheet, there's no need to worry about design and how it will be organized; the program will take care of t
Rainbow [258]
False: a computer program do many things, but it can't read your mind. It doesn't know what kind of formatting you need for your spreadsheet. There are so many potential layouts of a spreadsheet, that the computer couldn't decide what to lay it out for you. Eventually the computer can see what you're trying to lay it out as and can help that way, but it needs to e started first. Having a uniform sheet that is well organized by you, is much easier to read than gobbledegook that has been spewed everywhere.

I hope this was helpful!
