Answer:
if (number > 30) {. . .}
Explanation:
This code block uses a simple if-elseif-else control structure to do a comparison on a value. In this type of control structure, each operation of control is check until the correct condition is met, and once the code executes, it exits the control structure, never touching the remainder of the structure.
In this example, we are fortunate that the value triggers the first part of the control structure with if (number > 30) and will execute that section of code. Once the code finishes, it will exit the structure, never making it to the other 3 control conditions.
Cheers.

How have search engines like Google, Bing, and Yahoo! revolutionized the ability to do research? They are more difficult to access than the library. They provide only information from reliable sources. They provide immediate access to information on the web. They take longer than using a card catalog but provide only expert sources.
Answer:
because it is easy to access not hard not all things from the internet are reliable they don't always have expert sources
Explanation:
Search engines like Google, Bing, and Yahoo! have revolutionized research.
The best answer choice for this is that "they provide immediate access to information on the web".
The other choices would be wrong because...
Answer choice A, would be incorrect due to the fact that using the search engines makes it easier to access information than a library as you do not need to walk around the library looking for a book to provide you the answers to your question.
Answer choice B, would be false since the web doesn't always provide only reliable information from creditable sources. In fact, quite a few of the sources on the web that come up, are not helpful or do not assist the user in answering their questions.
Answer choice D, would be wrong since using the search engine to find information is quicker than using a card catalog, and also it does not only provide expert sources since any source of information could pop up when the user searches for it.

What is the features of Mark 1
Answer:
Okay:
Mark I was enourmous in size, measuring 8 feet high, 51 feet long and three feet deep. It weighed 5 tons, used 530 miles of wire and 730,000 separate parts. The operation of these parts was powered and synchronized by a long horizontal rotating shaft. A four horsepower engine drives the mechanical parts.
Harvard Mark I, an early protocomputer, built during World War II in the United States. While Vannevar Bush was working on analog computing at the Massachusetts Institute of Technology (MIT), across town Harvard University professor Howard Aiken was working with digital devices for calculation. He had begun to realize in hardware something like the 19th-century English inventor Charles Babbage’s Analytical Engine, which he had read about. Starting in 1937, Aiken laid out detailed plans for a series of four calculating machines of increasing sophistication, based on different technologies, from the largely mechanical Mark I to the electronic Mark IV.

What are limitations of AI
Explanation:
Limitations of artificial intelligence. One of the main barriers to implementing AI is the availability of data. Data is often siloed or inconsistent and of poor quality, all of which presents challenges for businesses looking to create value from AI at scale.
Answer:
Risks and limitations of artificial intelligence in business
Businesses are increasingly looking for ways to put artificial intelligence (AI) technologies to work to improve their productivity, profitability and business results.
However, while there are many business benefits of artificial intelligence, there are also certain barriers and disadvantages to keep in mind.
Limitations of artificial intelligence
One of the main barriers to implementing AI is the availability of data. Data is often siloed or inconsistent and of poor quality, all of which presents challenges for businesses looking to create value from AI at scale. To overcome this, you should have a clear strategy from the outset for sourcing the data that your AI will require.
Another key roadblock to AI adoption is the skills shortage and the availability of technical staff with the experience and training necessary to effectively deploy and operate AI solutions. Research suggests experienced data scientists are in short supply as are other specialised data professionals skilled in machine learning, training good models, etc.
Cost is another key consideration with procuring AI technologies. Businesses that lack in-house skills or are unfamiliar with AI often have to outsource, which is where challenges of cost and maintenance come in. Due to their complex nature, smart technologies can be expensive and you can incur further costs for repair and ongoing maintenance. The computational cost for training data models etc can also be an additional expense.
Software programs need regular upgrading to adapt to the changing business environment and, in case of breakdown, present a risk of losing code or important data. Restoring this is often time-consuming and costly. However, this risk is no greater with AI than with other software development. Provided that the system is designed well and that those procuring AI understand their requirements and options, these risks can be mitigated.
See also Industry 4.0 challenges and risks.
Other AI limitations relate to:
implementation times, which may be lengthy depending on what you are trying to implement
integration challenges and lack of understanding of the state-of-the-art systems
usability and interoperability with other systems and platforms
If you're deciding whether to take on AI-driven technology, you should also consider:
customer privacy
potential lack of transparency
technological complexity
If you're considering writing a tender document to procure AI, you can seek help from the Northern Ireland Artificial Intelligence Collaborative Network(link is external).
AI and ethical concerns
With the rapid development of AI, a number of ethical issues have cropped up. These include:
the potential of automation technology to give rise to job losses
the need to redeploy or retrain employees to keep them in jobs
fair distribution of wealth created by machines
the effect of machine interaction on human behaviour and attention
the need to address algorithmic bias originating from human bias in the data
the security of AI systems (eg autonomous weapons) that can potentially cause damage
the need to mitigate against unintended consequences, as smart machines are thought to learn and develop independently
While you can't ignore these risks, it is worth keeping in mind that advances in AI can - for the most part - create better business and better lives for everyone. If implemented responsibly, artificial intelligence has immense and beneficial potential.

Draw a truth table & logic circuit corresponding to the following logic statement
X = 1 if ( ( M is 1 OR N is 1 ) AND ( M is 1 AND N is 1 ) ) OR ( O is NOT 1 )
Answer:
The truth table, as well as the logic circuit of the given statement, is attached below.
Explanation:
Logical gates seem to be the essential building blocks of just about any computerized signal. It becomes a digital device with one or even more inputs and therefore only single output. The arrangement among outputs and inputs would be focused on this kind of logic. Upon that basis, logic gates were already called as AND, NOT, OR gate, etc.

Why would you want to hyperlink objects into your own Google Slides presentation? (Select all that apply.) Select All Correct Responses For extending the learning experience for students. To make sure the presentation is linear So students can use the Slides for review and can go to additional resources outside of the presentation. To make the presentation more graphically appealing
The correct answers are A. For extending the learning experience for students. C. So students can use the Slides for review and can go to additional resources outside of the presentation. D. To make the presentation more graphically appealing
Explanation:
The use of hyperlink objects in presentations means objects such as images, texts, or icons are associated with links or websites students can easily access by clicking on the specific image or element. This might be used in educational contexts to allow students to have a complete learning experience by providing alternative and external sources outside the presentation. For example, if the topic is space hyperlinks to NASA website can be included. This means, hyperlink objects extend learning experiences and provide additional resources (Option A and D).
Besides this, this resource can make a presentation more appealing as links to images, videos, and other visually interesting resources can be included (Option D). However, it also breaks the linearity of the presentation as students will need to move to other websites as they go through the presentation.

An array of int named a that contains exactly five elements has already been declared and initialized. In addition, an int variable j has also been declared and initialized to a value somewhere between 0 and 3. Write a single statement that assigns a new
Answer:
a[j] = 2 * a[j+1];
Explanation:
The complete statement is to Write a single statement that assigns a new value to the element of the array indexed by j. This new value should be equal to twice the value stored in the next element of the array.
So lets say a is an array of type int which is already declared and initialized.
int a[] = {};
declare an int variable j as int j;
The element of array a indexed by j can be represented as a[j] This means the j-th index of array a
The value to be assigned to a[j] is 2 * a[j+1]; with an assignment operator "= " between a[j] and 2 * a[j+1]; in order to assign 2 * a[j+1]; to a[j]
According to the requirement this new value should be twice the value stored in next element of array. The next element of array is represented by a[j+1] which means j+1 index of array a. This means the element at j+1 index that comes after the element at j-th index a[j].
Value should be twice the value stored in next element of array means multiply the 2 with the next element of array i.e. a[j+1]
Now assign this new value 2 * a[j+1]; to a[j].
