Answer:

No output is generated

Explanation:

(1) The first line initialized an empty string, str

(2) The for loop attempts to iterate through the empty string. Since it is an empty string, no iteration will be done.

This implies that, the print statement within the loop block will not be executed.

Hence:

No output is generated

Based on the scenario above about the leading-trailing system Both technician A and B are incorrect.

<h3>How many brake shoes function?</h3>

There are known to be two shoes function that are said to be working a way where both become either the trailing shoe or leading shoe based on whether the vehicle is moving forward or backward.

Therefore we can say that, Based on the scenario above about the leading-trailing system Both technician A and B are incorrect.

2. Consider a 2 GHz processor where two important programs, A and B, take one second each to execute. Each program has a CPI of

allsm [11]

Answer:

program A runs in 1 sec in the original processor and 0.88 sec in the new processor.

So, the new processor out-perform the original processor on program A.

Program B runs in 1 sec in the original processor and 1.12 sec in the new processor.

So, the original processor is better then the new processor for program B.

Explanation:

Finding number of instructions in A and B using time taken by the original processor :

The clock speed of the original processor is 2 GHz.

which means each clock takes, 1/clockspeed

= 1 / 2GH = 0.5ns

Now, the CPI for this processor is 1.5 for both programs A and B. therefore each instruction takes 1.5 clock cycles.

Let's say there are n instructions in each program.

therefore time taken to execute n instructions

= n * CPI * cycletime = n * 1.5 * 0.5ns

from the question, each program takes 1 sec to execute in the original processor.

therefore

n * 1.5 * 0.5ns = 1sec

n = 1.3333 * 10^9

So, number of instructions in each program is 1.3333 * 10^9

the new processor :

The cycle time for the new processor is 0.6 ns.

Time taken by program A = time taken to execute n instructions

= n * CPI * cycletime

= 1.3333 * 10^9 * 1.1 * 0.6ns

= 0.88 sec

Time taken by program B = time taken to execute n instructions

= n * CPI * cycletime

= 1.3333 * 10^9 * 1.4 * 0.6

= 1.12 sec

Now, program A runs in 1 sec in the original processor and 0.88 sec in the new processor.

So, the new processor out-perform the original processor on program A.

Program B runs in 1 sec in the original processor and 1.12 sec in the new processor.

So, the original processor is better then the new processor for program B.

}

$\text{public void}$ setTitle( $\text{String title}$ ) {

this. $\text{title}$ = $\text{title}$ ;

}

$\text{public String}$ getAuthor() {

An Output report is known to be the various findings that has been generated or it is said to be the result of a given program outcome.

<h3>What is an output report?</h3>

An output is known to be a file that has been produced by the system when a user is said to have submitted a Program, Report Set, etc. for execution.

Note that to be able to compile the GPSSWorld program, one has to use a statistical software to create the output and charts, and then one can copy and paste the results unto any given word processor software where one can construct a table for it.
