______ is an example of unauthorized access to your computer or accounts.
pychu [463]
Well, it wouldn't be Adware because that just has to do with ads and stuff...
It wouldn't be cookies either because they just store things to make life easier.

It would be between Phishing and Hacking. I don't think it's Phishing because that's tricking someone into giving them your account information.

I think it would be hacking.

I hope that this helps. If it does, please rate it as Brainliest :D

Consider two different implementations, M1 and M2, of the same instruction set. There are three classes of instructions (A, B, a
ANTONII [103]

Answer:

a) the average CPI for machine M1 = 1.6

the average CPI for machine M2 = 2.5

b) M1 implementation is faster.

c) the clock cycles required for both processors.52.6*10^6.

Explanation:

(a)

The average CPI for M1 = 0.6 x 1 + 0.3 x 2 + 0.1 x 4

= 1.6

The average CPI for M2 = 0.6 x 2 + 0.3 x 3 + 0.1 x 4

= 2.5

(b)

The average MIPS rate is calculated as: Clock Rate/ averageCPI x 10^6

Given 80MHz = 80 * 10^6

The average MIPS ratings for M1 = 80 x 10^6  / 1.6 x 10^6

= 50

Given 100MHz = 100 * 10^6

The average MIPS ratings for M2 = 100 x 10^6 / 2.5 x 10^6

= 40

c)

Machine M2 has a smaller MIPS rating

Changing instruction set A from 2 to 1

The CPI will be increased to 1.9 (1*.6+3*.3+4*.1)

and hence MIPS Rating will now be (100/1.9)*10^6 = 52.6*10^6.
