Consider a processor with a 2 ns clock cycle, a miss penalty of 20 clock cycles, a miss rate of 0.05 misses per instruction, and a cache access time (hit time) of 1 clock cycle. Assume that the read and write miss penalties are the same.

a. Find the average memory access time (AMAT).
b. Suppose we can improve the miss rate to 0.03 misses per instruction by doubling the cache size. However, this causes the cache access time to increase to 1.2 cycles. Using the AMAT as a metric, determine if this is a good trade-off.
c. If the cache access time determines the processor’s clock cycle time, which is often the case, AMAT may not correctly indicate whether one cache organization is better than another. If the processor’s clock cycle time must be changed to match that of a cache, is this a good tradeoff?

Assume that the processors in part (a) and (b) are identical, except for the clock rate and the cache miss rate. Assume 1.5 references per instruction (for both I-cache and D-cache) and a CPI without cache misses of 2. The miss penalty is 20 cycles for both processors.

Answer:

Clear out unused files

Explanation:

The reason whay the hard drive is so slow is probably because it full of junk. The recycle bin, old update files, cached data, etc. can easily fill up the hard drive, thus slowing it down.

1.3 million Earths.

The answer is that it would take 1.3 million Earths to fill up the Sun. It would take so much Earths to fill the Sun because the Sun makes up 99.86% of the mass of the Solar System, so a lot of Earths would be needed to fill up the Sun.

Answer:

cloud computing

Explanation:

Answer and Explanation:

Given the table,

Number of Terminal visitors:

FRR:

FAR:

Number of Terrorists:

Number of Terrorists identified:

Number of Legitimate passengers: Number of Passengers incorrectly identified:

We fill the table,

Number of Terminal visitors: 10,000,000

FRR: 3,000,000

FAR: 100,000

Number of Terrorists: 10

Number of Terrorists identified: 3,000,010

Number of Legitimate passengers: 9,999,990

Number of Passengers incorrectly identified: 3,100,000

Number of passengers incorrectly identified as terrorists : 3,000,000

Note:

1. Number of terminal passengers is 10 million from question(number of passengers entering the country from all airports in the country)

2. The False Rejection Rate(FRR) is the rate of rejection of authorised passengers by the biometric system. It is 30% here. We calculate 0.30*10 million= 3 million

3. False Acceptance Rate(FAR) is the rate of acceptance of unauthorized passengers by the biometric. It is 1% here. We calculate 0.01*10 million= 100000

4. Number of Terrorists is equal to 10 since one in one million people are terrorists. 10 million people would then have 10 terrorists.

5. Number of Terrorists identified: number of terrorists would be number of falsely identified terrorists 3 million + number of terrorists 10 = 3,000,010 ( assuming that all terrorists were identified)

6. Number of Legitimate passengers: number of legitimate passengers = 10 million passengers- number of terrorists 10= 9,999,990

7. Number of Passengers incorrectly identified: number of passengers incorrectly identified is equal to falsely rejected passengers(FRR) 3 million + falsely accepted passengers 100000= 3,100,000

8. Number of passengers incorrectly identified as terrorists is equal to falsely rejected passengers (FRR) =3,000,000

Following are the code to this question:

#include <iostream>//defining header file

#include <cstdlib>//defining header file

using namespace std;

int main()//defining main method

{

const int ax[10]={1,2,3,4,5,6,7,8,9,10};//defining a const array ax that store 10 numbers

int r_num[10];//defining an array r_num

int i;//defining integer variable

for(i=0;i<10;i++)//defining for loop to calculate and store random numbers in array

{

   r_num[i]=rand()%100; //use rand function to store value in array

}

cout<<"Elements of the array that stores 10 random numbers: "<<endl;//print message

for(i=0;i<10;i++)//defining for loop for print array value

{

   cout<<r_num[i]<<endl;//print array value

}

return 0;

}

Output:

Elements of the array that stores 10 random numbers:  

83

86

77

15

93

35

86

92

49

21

Explanation:

In the above-given program, two arrays "ax, and r_num" is declared that store value in it, in which the ax array use the const keyword and in the r_num it uses the loop and random function which can be defined as follows:

In the second array "r_num", two for loop is declared, in which the first loop uses the rand function to store value in the array, and in the second array, it prints the value of the array.

Answer:

SELECT product_name, amount_due, amount_paid,

              cancelled, amount_refunded

   FROM products

ORDER BY product_name ASC;

Explanation:

SQL (Structured Query Language ) was used above.

The SELECT command is used to list all the variables we want in our output.

The FROM command signifies the location.

ORDER BY command ensures that your result is ordered

ASC means Ascending Order.

; signifies the end of the query.

NOTE: Underscores were used because variables cannot be written with spaces between them

Answer:

The space available will vary between 800 GB (100%) and 400 GB (50%) of the total disks, depending on the RAID level.

The OS will handle the RAID as a single disk.

Explanation:

Each RAID level implements parity and redundancy in a different way, so the amount of disks used for this extra information will reduce the space available for actual storage.

Usual RAID levels are:

RAID 0: does not implement any redundancy or parity, so you will have available 100% of the total storage: 8 x 100 GB = 800 GB

RAID 1: Duplicates all the information in one disk to a second disk. Space is reduced in half: 400 GB

RAID 5: Uses the equivalent of 1 disk of parity data distributed evenly on each disk, meaning the space available is [tex]\frac{n-1}{n}[/tex] of the total disks: [tex]\frac{7}{8}[/tex] of 800 GB = 700 GB

Writting and reading the information on a RAID storage is handled by a raid controller, either implemented in hardware or software. The OS will "see" a single disk and will read or write information as usual.

Written in Python:

rows = 8

for i in range(1,rows+1):

      for j in range(1,rows):

             print(" ")

      x = 1

      for j in range(1,i):

             print(str(x)+" ",end='')

             x = int(x*2)

      while x >= 1:

             print(str(x)+" ",end='')

             x = int(x/2)

Explanation:

For each row, the print out is divided into two parts.

1. Starts from 1 and ascends to a peak

2. Then descends from the peak to 1

This line initializes the number of rows to 0

rows = 8

This iterates from 1 to the number of rows

for i in range(1,rows+1):

This prints a blank at the end of sequence printed on each line

      for j in range(1,rows):

             print(" ")

This initializes each row element to 1

      x = 1

This iterates the number of item to print on each line depending on the row

      for j in range(1,i):

This prints the row element in ascending order to the peak

             print(str(x)+" ",end='')

This calculates the next element to be printed

             x = int(x*2)

This checks for valid row element to print in descending order to 1

      while x >= 1:

             print(str(x)+" ",end='')

             x = int(x/2)

Answer:

Written in Python:

def licenseNum(licenseYear, customID):

    output = 100000 * customID + licenseYear

    print("Dog license: "+str(output))

Explanation:

This line defines the function with parameters licenseYear and customID

def licenseNum(licenseYear, customID):

This calculates the output as stated in the question

    output = 100000 * customID + licenseYear

This displays the output

    print("Dog license: "+str(output))

To call the function, make use of: licenseNum(2014, 777)

Where 2014 and 777 can be replaced with other digits as required

Answer: C++

void DogLicense:: CreateLicenseNum(int customID)   {

  licenseNum = (100000* customID) + licenseYear;

  return;

}

A) The ways a user moves from one display to another

Explanation:

The interface is the point of interconnection between a user and a system. On the other hand, the dialogue shows the sequence of interactions between a user and a system. In the dialogue section, computation is formatted just like paper-based forms. So, for interface and dialogue designs, one additional subsection is included: a section outlining the dialogue sequence which is The ways a user moves from one display to another.

This additional subsection shows how the user is shifted from one screen to another screen or can say it as " moves from one display to another" and it is carried out for dialogue design and outlining dialogue sequence.

Answer:

Network or next hop associations

Explanation:

In a network that uses distance-vector routing protocols, the information that is included in the update sent out by each router is "network or next hop associations."

This information is contained in a routing table. It commands a router on which destination is most favorable. It is done by carrying the packet to a certain router that indicates the next hop along the way to the last destination.

In a network that uses distance-vector routing protocols, the information that is included in the update sent out by each router is the network or next hop association.

A distance-vector routing protocol in data networks is vital for determining the best route for the packets that are based on the distance.

It should be noted that distance-vector routing protocol simply measures the distance based on the number of routers that a packet will have to pass. The information that is vital will be the network or next hop association.
