Virus.

A virus is a malicious program or script that Spreads.

Malware, however, will not spread.

Viruses can spread without a victim's permission because it is automated to do so.

For example, the Melissa virus would look like a file attachment that used reverse psychology to make you open it. From there, it goes through the first 50 email contacts stored on your computer and sends the virus to them from your computer.

Suppose that we want to enhance the processor used for Web serving. The new processor is 10 times faster on computation in the W

elena55 [62]

Answer:

The overall speedup gained by incorporating the enhancement is 1.563

Explanation:

Using Amdahl's Law;

The overall speedup $(N) =\dfrac{1}{(1-P) + ( \dfrac{P}{n})}$

where;

P = Fraction Enhanced for Old Processor

n = speedup enhancement as a result of the new processor

P = 40% = 0.40 and n = 10

∴

The overall speedup (N) is:

$=\dfrac{1}{(1-0.4) + ( \dfrac{0.4}{10})}$

$=\dfrac{1}{(0.6) + ( 0.04)}$

$=\dfrac{1}{0.64}$

= 1.563

Thus, the overall speedup gained by incorporating the enhancement is 1.563

The two roots of a quadratic equation, for example 2 + + = 0, can be obtained using the following formula: Two Roots: 1 = − + √

Vladimir79 [104]

lst = input("Enter a,b,c: ").split(",")

a = float(lst[0])

b = float(lst[1])

c = float(lst[2])

root1 = (-b + ((b**2-(4*a*c))**0.5))/(2*a)

root2 = (-b - ((b**2-(4*a*c))**0.5))/(2*a)

dis = b**2 - (4*a*c)

if dis > 0:

print("The roots are {} and {}".format(root1, root2))

elif dis < 0:

print("The equation has no real roots")

else:

print("The root is {}".format(root1))

I wrote my code in python 3.8. I hope this helps!
