The database model that uses a series of two-dimensional tables or files to store information is the ________________ model. This database model has become the most popular database structure, as it is used by most microcomputer DBMS packages:

Answer: trees

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.

Answer:

Technology is rapidly evolving over a short period of time. Which leads to a change in how people perceive and subsequently react to these fast paced advances.

Answer: try this one: It is impossible to see how technology will be applied to situations that have not yet occured.

Answer:

Method 1. Restart your computer

The first thing to try is restarting Windows. It sounds too simple, but it sometimes yields results.

Method 2. Update .NET framework

In most cases it's Microsoft .NET framework causing the issues. You can download the latest version of .NET Framework from Microsoft.

When it's installed (or re-installed) reboot and try your app or game again

Method 3. Enable Administrator rights

Try running the game or app with admin rights. To do that, right-click on the shortcut or the actual executable for the game, select Properties and open the Compatibility tab. Tick the 'Run this program as an administrator' box, and click on OK.

Method 4. Reinstall the app or game

You can uninstall and re-installing the game or program you're trying to run - simple but sometimes the quickest and most effective way to get rid of the error.

Method 5. Update Windows

Update Windows. In many cases Windows will automatically update, but to check, head to Control Panel and search for 'Windows Update'.

In later versions, including Windows 10, you can open the new Settings app (just search the Start menu or click the cog icon which appears just above the Windows logo when you click it in the bottom-left of the screen.

In the Settings app, click on Update & Security then you should see a button to check for updates:

Explanation:

Method 6. Run ChkDsk

Run chkdsk by opening cmd (search for it or press Win+R).

In the window type "chkdsk c: /f /r". If it is the primary windows disk, it will ask you to schedule it for next boot. When you restart, it will do a check before get to the login screen. Partitions or other drives can also be checked this way.

Method 7. Reinstall DirectX

This can be the fix for games that won't load. The way to do this depends on your version of Windows and which version of DirectX you need. There are full instructions on Microsoft's website

Hope it's help you. :-)

Answer:

ICT is the abbreviated form of Information and Communication. It included different technologies like mobile phones, computers, USBs etc.

Following are two precautionary measures which should be observed when using any kind of ICT:

Answer:

D) MXN, ZAR, HKD

Explanation:

Exotic currencies refer to currency that are used in countries with emerging economies therefore they lack liquidity, are extremely volatile and have very low volumes. The exchange rate of exotic currencies are usually very high because of its lack of liquidity, therefore trading these currencies are expensive. Examples of exotic currencies are South African rand (ZAR), Mexican peso (MXN), Hong Kong dollar (HKD), Chinese yuan (CYN), Turkish lira (TRY) and so on.

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.

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.
