Who is known as the "father of computing"?
Mention his contributions?
Answers
Answer: Charles Babbage
Explanation:
He was named father of computing because of the invention of the Analytical Engine in 1837. This machine contained an integrated memory, a ALU (arithmetic logic unit) and a basic flow control. This machine gave birth to the notion of computer. Unfortunately, the machine wasn't built when Babbage was alive due to some funding issues.

Answer:
The answer is explained below
Explanation:
i) [tex]p(n) \ is\ an\ element\ of\ O(n^k)[/tex]
Therefore [tex]p(n)\leq c.n^k,therefore\ p(n) \ is\ an\ element\ of\ O(n^k)[/tex]

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.
Answers
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.

b. else if (number > 20) { . . .}
c. else if (number > 10) { . . .}
d. else { . . .}
Answers
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.

This is how a magnetic hard drive works
Explanation:
The hard drive contains a spinning platter with a thin magnetic coating. A "head" moves over the platter, writing 0's and 1's as tiny areas of magnetic North or South on the platter. To read the data back, the head goes to the same spot, notices the North and South spots flying by, and so deduces the stored 0's and 1's.

What are limitations of AI
Answers
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.
Why would you choose to use Word Art rather than a colored font when creating a Google Slides presentation? There are more fonts in Word Art Word Art has fewer graphical features Because color is always distracting Word Art lets you customize the look more
Answers
Answer:
D. Word Art helps you customize the look more.
Explanation:
Word Art is a design feature in Microsoft Word that helps users design creative texts. A placeholder text appears in the working area and instructs the user to enter his own text there. The size of the text can be adjusted according to the need of the user. A user can enter a simple sentence or a complete paragraph in the text and can customize the look according to his needs.
The letter A shows the different designs that can be applied by the user. Also, symbols can be inserted in the text. So, when creating a Google Slides Presentation, Word Art would be a preferred choice because of the ease in customizing.
