Chapter 10 Information and Technology skills


Pros of information Technology

Advantages of Information Technology

• Globalization
True globalization has come about only via this automated system. The creation of one interdependent system helps us to share information and end linguistic barriers across the continents. The collapse of geographic boundaries has made the world a 'global village'. The technology has not only made communication cheaper, but also possible much quicker and round the clock. The wonders of text messages, email and auto-response, backed by computer security applications, have opened up scope for direct communication.

• Cost-effective
Computerized, internet business processes have made many businesses turn to the Internet for increased productivity, greater profitability, clutter free working conditions and global clientèle. It is mainly due to the IT industry that business have been able to make their processes more streamlined, thereby becoming more cost-effective and consequently more profitable. People are able to operate their businesses 24x7, even from remote locations only due to the advent of information technology.

• Communication
Quick and effective communication is vital to any business anywhere in the world. Information technology gives an entrepreneur or business the tools, like email, video conferencing, SMS, etc., essential to communicate efficiently and effectively. to the business world, and information technology gives your company the resources it needs to communicate quickly and effectively. Not only do people connect faster with the help of information technology, but they are also able to identify like-minded individuals and extend help, while strengthening ties.

• Storing and Protecting Information
IT provides a low-cost business options to store and maintain information that may be important from a business or service point of view. Virtual vaults and other such security systems not only store vital data but also allow control over the access to such information. IT security systems will also protect virtual data from being hacked or wiped out in case of any technical failure.

• Creation of New Jobs
One of the biggest advantage of IT has been the creation of a whole new field of opportunity for skilled personnel leading to new and interesting jobs. Hardware and software developers, computer programmers, web designers, system analyst, the list of new jobs created could go on. IT has also been attributed to be the major cause of surge in the economies of certain Third World nations too.





Cons of Information Technology



It has taken away people’s Privacy
As IT-Sectors have wined the people’s heart worldwide. People are here to share and store any kind of information, private date in their hard drives and private online databases. But due to some Cyber-Criminals, nothing is SO Safe both online and offline. If someone becomes a bit careless, s/he may needs to pay high for it. (It’s serious).
The online community is not safe for Family anymore
Children under age may often share Cell Numbers, Private Email Address which can be hacked by people and can pass it to the criminals who have a blue-print to harm the society. And people are loosing credit card privacy and other payment processing options. Again, there are some sites created by Nasty Guys, which can lead under eighteen teenagers to a different path – That Is Going To Bring Harms To The Nation.
It is going to damage a Human’s Natural Power
We can think, gather human principles (ethical knowledge) and make co-operative relationships between friends and families. But due to harmful aspects of (IT) people are becoming fully technological based. And it can bring huge damage to the society as its taking away the natural thoughts and organic ideas.
It can bring World Destruction without Efficient Administration
This is an extra point which I am writing by remembering various Science Fictions. Great scholars have though about the matter wisely. Til now, we (humans) are possessing the leading place in the world and administering the computer technology. But a day MAY come when the technology is going to administer us in all aspects. It may probably happen that we are converted to the slaves of Technology.
So, by this cons I am not trying to tell that Technology is here to bring harms only, because I myself is a technological man who passes 24 hours browsing computer and talking on phones. But as a part of human society we need to give up a look at the both sides of IT.

Characteristics of a Good Website



Published March 4th, 2007 in Design
Free Website Builder
What makes a website successful? Keep the following points in mind when creating your website to get the most out of it:
  • Content
Quality content on your website can provide users with the information they are looking for. Content also allows you to establish yourself as an expert in your field. When your website visitors are looking to make a purchase they will feel more comfortable with your products and services if you have built their trust and confidence through what you have written on your website.
Keyword-filled content is also crucial for getting high search engine rankings. Most internet users trust search engines to help them find what they are looking for. Taking the time to create high quality content can have huge payoffs through increased search engine rankings.
  • Simple and Attractive Design
The design of a good website should be simple, yet professional. The design should not take away or distract from the content. Websites with excessive use of Flash and moving images can be very distracting. Use design to help you get your message to visitors, not to distract them from the message. Colors should not be hard on the eyes, and text should be easy to read.
  • Easy Navigation
Navigation and links provide opportunities to incorporate design elements in to the website; however, navigation schemes should not be so elaborate that the user has trouble knowing where to click to move to another page. The average visitor’s attention span is a matter of seconds, and if it is hard to find what he or she is looking for, you will loose that visitor very quickly. Links to your most important pages should be easily found on every page. A good rule of thumb is that every page should be accessible in two clicks from your home page (this may not be possible with larger sites).
  • Unique
The most successful websites will stand out from the crowd. There are a number of was that you can make your website stand out: better design, high quality articles, a blog, a newsletter, some type of resource or tool. Find something that would be appealing to your target market.
  • Fresh
Having a website that changes or is updated frequently will encourage repeat visitors. Repeat visitors will be more loyal and more likely to buy. There are a few different options for keeping your site fresh:
1- Update the site and add content occasionally – This will require you to either pay a designer or do the work yourself.
2 – Use a blog – With a blog you can add content to your website from any computer with an internet connection. All you’ll have to do is login and type. No special software or skills are required.
3 – RSS feeds – With RSS feeds you can add news headlines, weather, stock tickers, etc. to your website. Additionally, you can add content from most blogs to your site with RSS. The benefit of RSS feeds is that once in place they will automatically update.
  • Optimized
A successful website will be search engine-friendly. Optimization includes things like using page titles and meta tags for all of your pages. Using headers and alt tags for images can also help optimization and accessibility. Even a website that is strong in other areas but weak in optimization may be hard for users to find.




Information Bias



Description

When we are trying to make a decision, we generally seek data on which to rationally base the choice. Where this goes wrong, is when we assume that all information is useful, and that 'more is better'.
Sometimes, extra information adds no significant value. Sometimes it simply serves to confuse.

Research

Baron, Beattie, and Hershey (1988), gave subjects a diagnostic problem involving fictitious symptoms, tests and diseases. Many subjects said they would need additional tests even when they had sufficient data.

Example

A manager gets consultants to do a study of the marketplace when a third party report is already available at far less cost.

So What?

Using it

When you want people to pay attention to your information, even when they have other information you may well be able to present it, for example as 'new findings'.
You can also deliberately create overload by encouraging people to seek more and more data.

Defending

Think first about what information you need and go for that which is just sufficient and necessary.
