What are two names for the database that holds digital signatures provided by os manufacturers, such as microsoft and red hat?

Consider two different implementations, M1 and M2, of the same instruction set. There are three classes of instructions (A, B, a

Margaret [11]

Explanation:

A.)

we have two machines M1 and M2

cpi stands for clocks per instruction.

to get cpi for machine 1:

= we multiply frequencies with their corresponding M1 cycles and add everything up

50/100 x 1 = 0.5

20/100 x 2 = 0.4

30/100 x 3 = 0.9

CPI for M1 = 0.5 + 0.4 + 0.9 = 1.8

We find CPI for machine 2

we use the same formula we used for 1 above

50/100 x 2 = 1

20/100 x 3 = 0.6

30/100 x 4 = 1.2

CPI for m2 = 1 + 0.6 + 1.2 = 2.8

B.)

CPU execution time for m1 and m2

this is calculated by using the formula;

I * CPI/clock cycle time

execution time for A:

= I * 1.8/60X10⁶

= I x 30 nsec

execution time b:

I x 2.8/80x10⁶

= I x 35 nsec

Assume that source elements of length k are mapped in some uniform fashion into a target elements of length p. If each digit can

lukranit [14]

Answer And explanation

a)

$r^k$ has 1/ $r^k$ probability guess the correct source

b)

Each element in $r^p$ is mapped by $r^k$ / $r^p$ . There are $r^k^-^p$ So there are $r^k^-^p$ -1 elements.

number of target elements = $r^k^-^p$

number of source elements = $r^k^-^p$ -1

probability = $r^k^-^p$ -1 / $r^k$

c) Probability of the correct target element

1/ $r^p$

public class HollowSquare

{

public static void main(String args[])

{

Scanner scan = new Scanner(System.in);

int size;

System.out.print("Enter the size : ");

size = scan.nextInt();

if(size>=1 && size<=20)

{

for(int i=0; i<size; i++)

{

for(int j=0; j<size; j++)

{

if(i==0 || j==0 || i==size-1 || j==size-1)

System.out.print("*");

else

System.out.print(" ");

}

System.out.println();

}

else

System.out.println("Invalid size.");

Sati [7]

Answer:

True

Explanation:

Outsourcing, in a general term, means getting help from an external source. In software development context, outsourcing is an alternative systems building approach that may involve subscribing to an application service provider or hiring an external vendor to design and create software. In outsourcing, a business employs the service of a third-party application developer to design and create a software.

Some reasons why companies outsource a service are;

i. Shortage or lack of experienced developer in-house.

ii. To save time. Outsourcing can help reduce time taken to develop a software application because companies tend to outsource a developer that has designed similar application(s) in the past.

iii. To reduce cost. Outsourcing can help save cost considerably.
