Answer:

Dots per Inch

Explanation:

Dots per Inch (DPI) in print is dependent on how you want your final image to look. It is the amount of resolution in picture. The logic is pretty simple. The more you are able to squeeze your dots per inch in an image, the more the image becomes crisp and sharp and vice versa. Consequently, it will result to a high resolution which will again translate to more sharpness.

A predictive data analyst___.

fgiga [73]

Answer:

C. analyzes data and trends and predicts future data and trends.

Explanation:

Predictive analytics can be defined as a statistical approach which typically involves the use of past and present data ( factual informations) in order to determine unknown events or future performances of a business firm or organization. It is focused on determining what is likely to happen in the future.

For example, a data analyst trying to determine how to effectively stock his company's warehouses incase of an anticipated pandemic and he's using current sales data to project the demands.

Hence, a predictive data analyst is an individual who analyzes data and trends and predicts future data and trends.

A common fallacy is to use MIPS (millions of instructions per second) to compare the performance of two different processors, an

yulyashka [42]

The question is incomplete. It can be found in search engines. However, kindly find the complete question below:

Question

Cites as a pitfall the utilization of a subset of the performance equation as a performance metric. To illustrate this, consider the following two processors. P1 has a clock rate of 4 GHz, average CPI of 0.9, and requires the execution of 5.0E9 instructions. P2 has a clock rate of 3 GHz, an average CPI of 0.75, and requires the execution of 1.0E9 instructions. 1. One usual fallacy is to consider the computer with the largest clock rate as having the largest performance. Check if this is true for P1 and P2. 2. Another fallacy is to consider that the processor executing the largest number of instructions will need a larger CPU time. Considering that processor P1 is executing a sequence of 1.0E9 instructions and that the CPI of processors P1 and P2 do not change, determine the number of instructions that P2 can execute in the same time that P1 needs to execute 1.0E9 instructions. 3. A common fallacy is to use MIPS (millions of instructions per second) to compare the performance of two different processors, and consider that the processor with the largest MIPS has the largest performance. Check if this is true for P1 and P2. 4. Another common performance figure is MFLOPS (millions of floating-point operations per second), defined as MFLOPS = No. FP operations / (execution time x 1E6) but this figure has the same problems as MIPS. Assume that 40% of the instructions executed on both P1 and P2 are floating-point instructions. Find the MFLOPS figures for the programs.

Answer:

(1) We will use the formula:

CPU time = number of instructions x CPI / Clock rate

So, using the 1 Ghz = 10⁹ Hz, we get that

CPU time₁ = 5 x 10⁹ x 0.9 / 4 Gh

= 4.5 x 10⁹ / 4 x 10⁹Hz = 1.125 s

and,

CPU time₂ = 1 x 10⁹ x 0.75 / 3 Ghz

= 0.75 x 10⁹ / 3 x 10⁹ Hz = 0.25 s

So, P2 is actually a lot faster than P1 since CPU₂ is less than CPU₁

(2)

Find the CPU time of P1 using (*)

CPU time₁ = 10⁹ x 0.9 / 4 Ghz

= 0.9 x 10⁹ / 4 x 10⁹ Hz = 0.225 s

So, we need to find the number of instructions₂ such that CPU time₂ = 0.225 s. This means that using (*) along with clock rate₂ = 3 Ghz and CPI₂ = 0.75

Therefore, numbers of instruction₂ x 0.75 / 3 Ghz = 0.225 s

Hence, numbers of instructions₂ = 0.225 x 3 x 10⁹ / 0.75 = 9 x 10⁸

So, P1 can process more instructions than P2 in the same period of time.

(3)

We recall that:

MIPS = Clock rate / CPI X 10⁶

So, MIPS₁ = 4GHZ / 0.9 X 10⁶ = 4 X 10⁹HZ / 0.9 X 10⁶ = 4444

MIPS₂ = 3GHZ / 0.75 X 10⁶ = 3 x 10⁹ / 0.75 X 10⁶ = 4000

So, P1 has the bigger MIPS

(4)

We now recall that:

MFLOPS = FLOPS Instructions / time x 10⁶

= 0.4 x instructions / time x 10⁶ = 0.4 MIPS

Therefore,

MFLOPS₁ = 1777.6

MFLOPS₂ = 1600

Again, P1 has the bigger MFLOPS

Softa [21]

Answer:

E. Check the simple things first to make sure you do not miss anything

Explanation:

This first step is called troubleshooting. As a certified operator, you need to check the simple things first to make sure you don't overlook something in your diagnosis.

The client is fairly certain the problem is from the video card, so after checking the simple things first (troubleshooting) and see no problems, then you can check the video card of the computer.

The reason it is advisable to troubleshoot on the simple things is to make sure you don't overlook something and also that your mind isn't totally fixed on one particular thing which is the video card in this situation.

professor190 [17]

Both in my personal and professional life, I use the Excel software in order to create tables and lists. It's much easier to do that in Excel rather than in Word, for example, because Excel was actually created for that purpose, whereas Word was created for writing, above all. I use Excel for work to create tables of various things, such as names, emails, payments, etc. whereas I use it in my personal life to create lists of things such as movies, books, etc.
