Answer:
The answer is: Only A is correct.
Explanation:
Variables in a program can assume different values at different times, and the program can then produce different results, depending on circumstances, so A is correct.
In a computer language, a reserved word (also known as a reserved identifier) is a word that cannot be used as an identifier, such as the name of a variable, function, or label – it is "reserved from use". This is a syntactic definition, and a reserved word may have no meaning. So, B is incorrect.
Hence, the answer is: Only A is correct.
Three enhancements with the following speedups are proposed for a new machine: Speedup (a) = 30, Speedup (b) = 20, and Speedup (c) = 15.
Answer:
mark me brainlist please
Explanation:
Three enhancements with the following speedups are proposed for a new machine: Speedup (a) = 30, Speedup (b) = 20, and Speedup (c) = 15. C should be have highest enhancement.
What is speedups?Speedup is a metric used in computer architecture to compare how two systems perform when solving the same task.
Technically speaking, Speedup is the increase in task execution speed when performed on two comparable architectures with various resources.
Further Amdahl's law, which was primarily focused on parallel processing, developed the idea of speedup. However, speedup can be applied more broadly to demonstrate how resource improvements affect performance.
[tex]{\displaystyle L = frac 1 v = frac T W, where L = frac 1 v = frac T W.[/tex]
Where v is the task's execution speed, T is the task's execution time, and W is the task's execution workload.
Further The rate at which a task is executed is the throughput of an architecture:
[tex]displaystyle Q=rho vA=frac rho AWT=frac rho AL, Q=rho vA=frac rho AWT=frac rho AL[/tex]
Throughput and latency are two different types of quantities for which speedup can be defined. The relationship between latency and task execution speed is reciprocal.

Define basic logical gates with its symbol, algebraic expression and truth table.
Answer:
A truth table is a good way to show the function of a logic gate. It shows the output states for every possible combination of input states. The symbols 0 (false) and 1 (true) are usually used in truth tables. The example truth table shows the inputs and output of an AND gate.
Explanation:
Designers are comparing performance between a multi-core processor equipped with 16 in-order cores and a dual-core superscalar processor. The dual-core superscalar processor has two identical Out- of-Order cores. Each core is a 4-issue superscalar. The multi-core processor has 16 in-order processor cores. Each in-order core of the multi-core processor can achieve about one third the performance of the OoO superscalar core. A benchmark program K includes both sequential codes that can only be executed on one CPU core and parallel codes that can be distributed to multiple CPU cores. For program K, execution of the sequential codes takes 30% of the total execution time.
Required:
Which processor would deliver faster performance for benchmark program K and show your calculations?

Why were Daguerreotype cameras not intended for the general public?
Answer:
The exposure time was vastly too long to be intended for practical use by photographers.
Explanation:
"The very first daguerreotype cameras could not be used for portraiture, as the exposure time required would have been too long. The cameras were fitted with Chevalier lenses which were 'slow' (about f/14). They projected a sharp and undistorted but dim image onto the plate."

Programming challenge description: In this challenge, you're given a string containing jumbled letters from several concatenated words. Each word is a numeral from zero to nine. Each numeral may be used multiple times in the jumbled string. Write a program that returns integers corresponding to the numerals used to form the jumbled string. Integers must be sorted in ascending order. For example, reuonnoinfe are shuffled letters of the strings one four nine. Your program's output should be 149. Input: A string formed from jumbled letters of numerals. For example:
Following are the Java program to the given question:
import java.util.*;//import package
public class Jumbledletters //defining Jumbledletters class
{
public static void main (String[] axv)//defining main method
{
String num[] = {"zero", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine"};//defining an arrayof string
int i,j;
Scanner xc = new Scanner(System.in);//creating Scanner class object to input value
System.out.print("Enter value: ");//print message
String v= xc.next();//defining a String variable that input String value
for(i=0; i<num.length; i++)//defining a loop to count input String length
{
String s = num[i];//defining a string variable to hold array value
boolean f = true;//defining a boolean variable
for(j=0; j<s.length(); j++)//defining a for loop that convets value into integer
{
char c = s.charAt(j);//defining char variable that hold value
if(v.indexOf(c)==-1)//defining if block to check indexOf value
{
f = false;//use boolean variable that hold boolean value
break;//using break keyword
}
}
if(f) //use if to check boolean value
System.out.print (i);//use print method that print i value
}
System.out.println();//use print method for beak line

What is the most helpful way to adopt the practice of design thinking, regardless of which framework is your favorite?
Answer:
Defining, framing and solving problems from users' perspectives
Explanation:
Stretching, walking, and meditation because stretching allows everything to be loosened or not as firm walking is part of everyday life and meditation is sitting in a calm comfortable position typically with calm music as well to clear your mind.
Why these are considered as very complex?These are all very complex because they require strength in your body and some people can't do these. Some have bad kneens so lunges can seriously hurt them others have weak arms so they can't push or hold their body wait for long periods of time and squats are difficult to do in the correct position because we can't typically do that without an actual chair
My most favorite are jumping jacks and meditation. Jumping jacks because it gets your adrenaline pumping and meditation because you can only hold so much in your mind before you get tired out. My least favorite are squats and planks. Squats are very difficult to do because you are litteraly sitting down with your back straight and the same dip of a chair but without it actually there do it's very complex.

HOMEWORK: Bud, Not Buddy I NOTICE... What do you see? chpter 3-4
Answer:
Check Explanation for Chapter 3 - 4 Summary!
Explanation:
Chapter 3:
Bud tries hard not to panic in the pitch-black darkness of the shed. The eyeballs of three dried-out fish heads stare back at him as he tries the doorknob, which he hopes Mr. Amos only pretended to lock. While deciding where to lay his blanket and pillow, he remembers the story of the cockroach crawling into his best friend’s ear back at the Home. From the story his friend, Bugs, tells, the cockroach was yelling, “My legs! My legs! Why have they done this to my legs?” while adults tried to extract it with tweezers. Bud wants to avoid any encounters with the cockroaches that are surely crawling over the shed’s floor, ready to crawl in his ears. He spreads his blanket on the top of the woodpile and climbs up.
Bud attacks the bat with a rake, only to discover that he has disturbed a hornet’s nest. Hornets sting him as he grabs for the doorknob hoping for escape. In his haste, he forgets about the fish heads with their razor-like teeth. He screams as the teeth cut into him, and the hornets continue to sting. He manages to escape through a window above the wood pile and falls to the ground, slapping at the hornets still attacking him. He heads towards the Amoses’ house, set on revenge.
Chapter 4 Summary:
Bud climbs into the Amoses’ house through an unlocked window. He finds his suitcase still under the kitchen table and puts it on the back porch step. Back in the house, he grabs Mr. Amoses’ shotgun and hides it outside, so if the Amoses wake up, they wouldn’t use it on him.
Bud returns to the kitchen. He fills a glass with warm water and heads up to Todd’s room. Todd is sound asleep. Bud dips Todd’s fingers in the warm water, hoping he’ll wet his bed. When he doesn’t, Bud pours the water on Todd’s pajama pants, causing Todd to soak his sheets. Bud creeps out of the house, grabs his suitcase, and heads toward the road, now “on the lam ... just like Public Enemy Number One.”

1. What kind of metrics would be useful that are based on testing knowledge after security awareness training? The metrics could be obtained immediately after training or at periodic intervals over several months.
Answer:
i hope it will helpful for your
mark me brainlist
Explanation:
Metrics refer to a system or standards of measurement.
These are measures of quantitative assessment for the purpose of comparing, tracking and performance measurement.
When it comes to measuring employee's awareness, people's knowledge of comprehensive security awareness it can be monitored through online security awareness programs. The knowledge of the employees can be tested in regard of a hot topic i.e cybersecurity practices.
Online quizes can be used to show whether employees know the risks of leaving a computer unmonitored.
Simulated or planned cyber attacks, mockdrills can be planned by the company to test the presence of mind, readiness of employees after the training.
These things should be done without any prior notice so that the employees feel the real pressure and the situation is same as the real world
The metrics used to test the security awareness of the trained staff must be consistent, cheap to gather, can be expressed as cardinal or in percentage , and most importantly they should be contextually relevant i.e they should faciliate decision makers to take actions and attain the desired objective.
Awareness surveys are important baseline to test the knowledge of employees after the training. They are simple to set up and easy to use as well.
For example- all employees know that there is a security team but do they know their goals and policies of the team. Awareness surveys can be used to check these parameters and get the desired results from it.
Online security awareness programs may be used to track people's understanding of complete security awareness.
What are metrics?The metrics used to assess the security awareness of the trained staff must be reliable, inexpensive to collect, expressed as a percentage or as a cardinal value, and most importantly, contextually relevant—that is, they must make it easier for decision-makers to take action and accomplish their goals.
As we know, online security awareness programs may be used to track people's understanding of complete security awareness when it comes to gauging employee awareness.
Employee expertise in relation to a current issue, such as cybersecurity procedures, can be evaluated.
Thus, online security awareness programs may be used to track people's understanding of complete security awareness.

Question 1. Mr. Beaver has four friends. They live in different houses. Each day he sets off from
home to visit one friend. When Mr. Beaver reaches a fork in the road he follows the arrow but, as
he passes, turns the arrow so that it now faces in the opposite direction. He always ignores the
arrows when retuming home.
On the first day he visits friend W. On day 2 he visits friend Y because he switched two arrows
around the day before. Etc.
2a) Which friend does Mr. Beaver visit on day 206? Explain your answer.
to come up with your answer
2b) Which aspect(s) of computational thinking were used
Answer:
2a) friend Y
2b) modulo calculations, state machines
Explanation:
After 4 days, history repeats itself. If you work out the first few days of the visiting pattern, you find that day 5 is identical to day 1.
So, if you divide the day number by 4 and take the remainder (i.e., the modulus), you get the original day number (where day 0 == day 4).
206 modulo 4 is 2, i.e., the second day where friend Y is visited.
The system behaves like a state machine with only 4 states.
