 Chapter-2 Usages of Internet

CHAPTER NO.2 USAGE OF INTERNET

INTRODUCTION

Internet is the one of the best technologies gifted to mankind in present scenario. It has brought the entire world at our fingertips. Today the use of Internet has increased tremendously.

In this chapter we will lear about Internet & World Wide Web. Also we will discuss about its applications, security, searching techniques and will learn about Google apps.

2.1 INTERNET

The name Internet itself suggests its meaning. It stands for Intemational network of computers. A network is a interconnection between two or more computers.(as already studied in previous classes) The Internet,sometimes simply called "The Net," is a global network

connecting millions of computers all over the world.

These computers are digitally connected to each other by cable, fibre or wireless links. We can use the internet

to browse websites, communicate with people, download pictures and videos, listen to music or do lots of other amazing things.

When two computers are connected over the Intemet, they can send and receive all kinds of information such as text, graphics, voice, video, and computer programs. We can get information, access data, shop, play games and many more with just a mouse click.

2.1.1 Internet Service Provider

Internet service provider (ISP) is a company that provides Internet connections and services to individuals and organizations. ISP makes the Internet a possibility. In other words, without

a subscription with an ISP, we won't have a connection to the Intemet. For a monthly rent, the service provider usually provides a software package, username, password and access phone number ¢.g. Airtel, Vodafone, Idea, BSNL, Jio etc.

Early ISPs provided Internet access through dial-up modems. This type of connection took place over regular phone lines and was limited to 56 Kbps.. In the late 1990s, ISPs began offering faster broadband Internet access via DSL and cable modems. Some ISPs now offer high-speed fibre connections, which provide Internet access through fibre optic cables.

ISPs may also be called IAPs(Intemmet Access Providers).

2.1.2 Web Browsers

A Web Browser or simply Browser is an application software that allows us to view and access websites on the Internet. It allows a user to locate, access and display web pages. User can request for any web page by just entering a URL (Uniform Resource Locator) in the address bar of the browser. A browser can show simple text, audio, video, hyperlinks and animations. The main function of the web browser is to fetch information resources from the

web and display them on a user's device

(@C, laptop, Mobile etc.). There are a lot

of browsers available in the market today.

Following is the list of some common web

browsers:

Microsoft Internet Explorer

Google Chrome

Apple Safari

Mozilla Firefox

Opera

2.1.3 Bookmarks and Favourites

As we know a Bookmark is a thin marker commonly made of card, metal, plastic or cord etc. Itis used to keep the reader's place in a book and enable the reader to return to it with ease.But when referring to an Internet Browser, it is a method of saving a web page's address. There

is no difference between bookmarks and favorites. They are different words that describe the same thing. Internet Explorer is the only major Web browser that uses the term “favorites.” A URL saved for future browsing in Mozilla Firefox, Google Chrome and Apple Safari is called a “bookmark.” With millions of websites coming online daily, we will certainly find ones we

want to revisit by using Bookmarks. Bookmarks and Favorites save Web addresses so that we can return to them quickly, without having to retype them. Whether we are using Mozilla Firefox, Internet Explorer, Safari, Chrome or another browser, the procedure is similar.

Adding Bookmarks:

Open the web page where we want to add a bookmark to.

Find the star on the address bar.

Click the star. A box will pop up.

Choose a name for the bookmark. Leaving it blank will only show the icon for the

site.

Choose what folder to keep it in.

Click Done.

2.1.4 Identify Secure Sites (HTTPS, Lock Symbol)

It's unfortunate that not every website is trustworthy and secure. An unsafe website can spread malware, steal information, send spam, and more. There are two simple ways to ensure that we are on a secure website.

1. Look at the web address in web browser, make sure the web address starts with https://

HTPS stands for Hypertext Transfer Protocol over Secure Socket Layer (SSL). It is the modification of HTTP used to secure the information between browser and server. It provides authentication and security for website information. HTTPS encrypts the information given by user side and decrypt the information from server side.

SSL Certificate provides security for the customer side information.

2. Look for a closed padlock in web browser.

Internet data travels from its starting point to its destination through numerous routes and relay points. At every point in the journey, it's possible that somebody could intercept and read the data. A green padlock indicates:

We are definitely connected to the website whose address is shown in the address bar; the connection has not been intercepted.

The connection between the browser and the website is encrypted to prevent spying.

When we click on the padlock we should see a message that states the name of the

company and "The connection to the server is encrypted” .

Note : Different web browsers have the padlock in different locations on the screen.

Important to Remember:

Do not log into a site if it is not secure as described above.

Do not log into a site if we feel it is a fake.

Log out of the site when we are finished.

A secure website creates an encrypted connection between our web browser and the site company web server. This encrypted connection prevents criminals on the intemet from spying on internet traffic with the purpose of stealing our information.

2.2 INTERNET AND ITS APPLICATIONS

2.2.1 Communication

The world is ever-changing and with the arrival of digital technology, it is changing at a very fast speed. Today Internet communication has made sure to connect people from two opposite sides of the earth with no problem at all.

Internet communication is referred to as sharing of information, ideas, or simply words over the Internet. Unlike before, people can stay at home and be connected to his or her family,friends, and even colleagues from anywhere around the world.

2.2.1.1 What Are the Advantages of Internet Communication?

Communication on the intemet has much more advantages than disadvantages.

Versatility - Internet communication is 24X7, as long as we're connected to the web.

When doing business, this can definitely help us.

Leveling - Some people are more comfortable talking behind their keyboards than

they do in person, thus enabling the reserved ones to produce well drawn out thoughts and not get sacred by "loud" people. This can also give them the sense of satisfaction (saying what they want to say with no one looking at them or giving them the eye").

Well-documented - Unlike usual face-to-face conversations, communication on the

internet is well-documented, thus creating a more responsible environment where

people are held answerable for their words.

Growing Community - Like all forms of communication, everyone can be shy at

first. However, in the case of internet communication, people are more likely to be

supportive and engaged in discussions than the other communication forms.

2.2.1.2 What Are the Types of Internet Communication?

With the advent of high-speed intemet connections, the internet has created more ways of instant communication that provide a vast option of information sharing.

Social Media Sites - Almost everyone with access to the web has a social media

account. Whether it be Facebook, Twitter, Instagram, or what ever account we have A

single post can connect us to a friend or loved one through means of "liking",

“sharing”, or "commenting".

Instant Messaging - Instant message or IM is sending a real-time message from one

user to another. Examples: Yahoo! Messenger, Windows Live Messenger etc.

E-mail - Electronic mail is the new version of the traditional mail. This is more likely

te be performed when engaging with a person officially.

Forum - Forums ate specifically directed to people who have questions or want to

start an idea or thought through group discussions. Each post is classified as a thread and is normally monitored by a mod, or moderator, who can either edit or remove

unnecessary posts that are irrelevant to the discussion at hand.

Blog- Consider this as our pre-internet journal or diary. Before, a journal zooms in on one person's life story. Now, a blog is used for more than life-sharing. People do

blogs to eam money by promoting products, information-sharing, giving tutorial, and.

even making political statements. People can comment and subscribe to their blogs if

they like the contents.

NOTE: When we're communicating on the Internet, we must take special care not to give out personal information to strangers and to treat others with respect. Be aware of the risks involved in communicating with those people that we cannot see and may never meet them personally. Take time to consider what we write to others, and be careful to avoid humour and sarcasm except with the best of friends. We can't assume that our messages are private, so be

careful about what we write.

2.2.2 Job Search

The internet is an excellent tool to locate a job. If we're looking for a job, the Internet is a great way to find

and apply for advertised jobs and to post our resume where employers can view it.

Ways to use the Internet for your job search:

Job search engines: Job search engines search only for jobs, so they can be more effective for work search than general search engines.

For example: monsterindia.com, naukri.com, naukriHub.com, timesjobs.com etc.

Social Media : Social Media can allow us to get up close and personal with potential

employers. Twitter (twitter.com) gives you the ability to follow companies and

recruiters, who may offer information about upcoming job openings. Similarly,Facebook (facebook.com) is filled with corporate pages that include career information.

Social media isn't just about receiving information; we can use it to contact potential emoployers and to actively network in our job search.

Visit employer websites to look for jobs and work opportunities : Many employers

prefer to hire directly through their websites, which are often a useful source to easily access information about their organizations.

2.2.2.1 Presenting Your Resume

Our job search isn't just about finding the right job; it's about convincing employers that we are the right person for the job. Don't start job search without giving due thought to our resume because a strong resume does wonders for our chances of making it to the interview stage.

2.2.3 Online Shopping

Online Shopping is the action or activity of buying goods or services over the Internet. In simple words it is a form of electronic commerce which allows consumers to directly buy goods or services from a seller over the Internet using a web browser. We can do online shopping from any online store(A website meant for online shopping).An

online store is a website through which customers place orders. It may represent a small local store, a major retailer,

an e-commerce store or an individual who sells products through a third-party site

2.2.3.1 Some famous online stores are:

Wwww.amazot.com

www.flipkart.com

www.snapdeal.com etc.

2.2.3.2. How to buy a product through online shopping:

1. If there's a particular brand or store we like, we can go straight to their website or we can visit a shopping website such as Amazon or flipkart etc., which carry broad

ranges of new and second-hand items.

2. Search for a product: Type the name of the item we want to buy into the search box

and click Search or press enter on our keyboard. This will give us items available

based on product reviews and price.

3. Add to basket or cart: Once you have chosen the amount and colour click on ADD TO

BASKET. Doing this will save the detuils of this item until we are ready to buy it.

4. Continue shopping or buy your product: We now have two choices either to Continue

Shopping if you wanted to buy other items from this website or to click on Go to Cart

and pay for the item we have chosen.

5. If we've finished shopping, click Proceed to Checkout.

6. Now sign in as a new customer.

7. Enter delivery address

8. Choose the payment option like by credit card or debit card

9. Fill the payment details(card details)

10. Then click on "place your order".

Because of the numerous advantages and benefits, more and more people these days prefer buying things online over the conventional method of going into stores. But it has some disadvantages also.

2.2.4 Travel

Travel is the movement of people between distant geographical locations. Travel can be done by foot, bicycle, train, boat, bus, airplane, ship or other means, with or without luggage.

The technological development has created an impact on all the aspects of human beings.

It includes the way how they travel as well. If we go to the internet, we will be able to see hundreds of travel related website. This is a strong example to indicate how technology has changed the travel and tourism industry within the past two decades.

2.2.4.1 How Internet helps in Travelling

Now people can travel to different destinations in the world at the comfort of their home.Technology along with enlarged reality has helped people to capture images and deliver them to the people in need through internet. On the other hand applications such as Google Street

View can help people to roam around streets with the help of their computers or mobile phones.

The popularity of smartphones has also helped people to travel without any hassle. In fact,people can simply find anything that they want with the help of their mobile devices while traveling.

The development of technology has also helped people to travel in a cost effective manner.For example, people had to purchase international calling cards when they travelled to a foreign country in the past. Now a variety of instant messaging and VOIP (voice over Internet Protocol) applications are available for them to communicate at a cheaper price tag.

Whenever we go to a new hotel or a restaurant, we would be going through the reviews that it has on Trip Advisor and other review platforms. Then we will be able to get a clear understanding about the service that we would receive at the end of the day.

We can even do ticket bocking at home, which can help us to save a considerable amount

of time. In fact, all the services that a traveller would need are available online. For example we can book our railway ticket online from the official website of Indian Railway (www.irctc.co.in).In order to book rail tickets online we need to have an IRCTC account.

Wecan do online train tickets booking by logging into the IRCTC (a subsidiary of the

Indian Railways) website directly or by secking help from licensed IRCTC agents

After that, we have to select the source and destination stations

Select preferred train

Check for train ticket availability

We have to fill the passenger details (Like: Name/s, age, gender, berth preference and

meal preference)

After completing all the personal details, proceed towards payment

Fill the details required at the time of payment

online train ticket booking is finalised once the payment is made

A message or email will be sent to the passenger's registered details

2.2.4.2 Facility of FASTag in travelling

FASTag is a tag which enables automatic deduction of toll charges and lets us pass

through the toll plaza without stopping for the cash transaction. FASTag is linked to a prepaid account from which the applicable toll amount is deducted. The tag employs Radio-frequency Identification (RFID) technology and is affixed on the vehicle's windscreen after the tag account is active.FASTag is a perfect solution for a hassle

free trip on national highways.

What are the benefits of using FASTag?

1. Ease of payment - The toll amount is automatically deducted from fastag prepaid

account, So no need to carry cash for the toll transactions, It also saves time.

2. Online Recharge - FASTag can be recharged online through Credit Card / Debit Card

/ NEFT/ RTGS or Net banking

3. SMS alerts for toll transactions, low balance, etc.

4. Online Portal for customers

5. Validity of 5 Years

2.2.5 Social Networking

Social networking is the use of Internet-based social media sites to stay connected

with friends, family, colleagues, customers,or clients. Social networking can have a social purpose, a business purpose, or both,through sites such as Facebook, Twitter,LinkedIn, and Instagram, among others.The internet changed the way people interact with each other as well as work culture, and those changes first arose on

social media sites. Social media helps people to establish better relationships with their family and friends. That is why people spend a lot of their time online browsing social sites, and usage has only gone up with increase in the use of smartphones and tablets etc.Some of the popular social networking sites are:

2.2.5.1 Facebook ; Facebook is the biggest social media site around, with more than two

billion people using it every month. That's almost a third of the world's population! There are more than 65 million businesses using Facebook Pages and more than six million advertisers actively promoting their business on Facebook. It's easy to get started on Facebook because almost all content format works great on Facebook - text, images, videos, live videos, and stories etc.

2.2.5.2 You Tube : YouTube is a video-sharing platform where users watch a billion hour of videos every day. We can create a YouTube channel for our brand where we can upload videos for our subscribers to view, like, comment and share.Besides being the second biggest social media site, YouTube (owned by Google) is also often known as the second largest search engine after Google.

2.2.5.3 WhatsApp : WhatsApp is a messaging app used by people in over 180 countries.

Initially, WhatsApp was only used by people to communicate with their family and friends.Gradually, people started communicating with businesses via WhatsApp.

2.2.5.4 Instagram : Instagram is a photo and video sharing social media app. Instagram

(owned by Facebook), was founded by Kevin Systrom and Mike Krieger in October 2010. The company operates independently of Facebook and is headquartered in San Francisco, Califomia.Instagram is an online social networking company that lets you share photos and videos,stories, and live videos with your followers.

Why is Instagram called Instagram?

Instant Camera + Telegram = Instagram

The name Instagram is a combination of the words “instant camera” and “telegram.”

Systrom wanted its name to be easy to pronounce and spell.

2.2.5.5 Twitter : Twitter is online news and social networking site where people

communicate in short messages called tweets. Tweeting is posting short messages for anyone who follows you on Twitter, with the hope that your messages are useful and interesting to someone in your audience.

2.3 INTERNET SEARCH

On the Internet, searching is just trying to find the information we need. The Internet is a big place, and getting information from it can seem a little discouraging. The Internet contains an unbelievable amount of information, which is really not all that useful unless we can find what we're looking for. Internet searching is one of the easiest and useful ways to use the Internet. There are endless reasons for why Internet searching is so helpful. People use common search engines to find web pages, images, books, currency conversions, definitions,file types, news, local information, movies, and many more.

2.3.1 Search Engines

Searching is one of the most popular activities on the internet. Search engines have become an essential part of everyone's lives. A search engine is a web-based tool that enables users to locate information on the World Wide Web. The engine provides a list of results that best match what the user is trying to find. An Internet search can generate a variety of sources for information. Results from online encyclopaedias, news stories, university studies, discussion boards, and even personal blogs can come up in a basic Intemet search. Popular examples of search engines are Google, Yahoo!, and MSN Search. Search engines utilize automated software applications (referred to as robots, bots, or spiders) that travel along the Web, following links from page to page, site to site. The information gathered by the spiders is used to create a

searchable index of the Web.

2.3.1.1 Google.com : Google Search Engine is the best search engine in the world and it

is also one of most popular products from Google. Almost 70% of the Search Engine market has been acquired by Google. What made Google the most popular and trusted search engine is the quality of its search results. Google is using sophisticated algorithms to present the most accurate results to the users. Google's founders name is Larry Page and Sergey Brin came up with the idea that websites referenced by other websites are more important than others and thus deserve a higher ranking in the search results.

2.3.1.2 Bing.com : Bing is Microsoft's answer to Google and it was launched in 2009.Bing is the default search engine in Microsoft's web browser. At Bing, they are always striving to make it a better search engine but it's got a long way to go to give Google competition. Bing is Microsoft's attempt to challenge Google in search, but despite their efforts, they still did not manage to convince users that their search engine can be a reliable alternative to Google.Their search engine market share is

constantly below 6%, even though Bing is the default search engine on Windows PCs.

Bing originated from Microsoft's previous search engines (MSN Search,

Windows Live Search, Live Search)

2.3.1.3 Wikipedia.com : Wikipedia is a free, open content online encyclopaedia created

through the collaborative effort of a community of users known as Wikipedians. Anyone registered on the site can create an article for publication; registration is not required to edit atticles. The site’s name comes from wiki, a server program that enables anyone to edit Web site content through their Web browser. Wikipedia provides us with all the information we need  and it also allows us to edit articles if we wish to. Everyone that wants to look for information about something will somehow go on Wikipedia. It is the largest and most popular reference work that is found on the Internet.

Jimmy Wales and Larry Sanger launched Wikipedia on January 15, 2001. At the very

beginning, Wikipedia was available only in English but later on was available in 295

languages.

2.3.1.4 Encyclopedia.com : As the Intemet's premier collection of online encyclopedias,

Encyclopedia.com provides us reference entries from credible, published sources like Oxford University Press and Columbia Encyclopedia.

At Encyclopedia.com, we get free access to nearly 200,000 reference entries from sources we can cite. Plus, more than 50,000 topic summaries feature related pictures, videos, topic summaries, and newspaper and magazine articles from around the world, Encyclopedia.com also provides innovative tools that allow us to rate and sort the reference content that we find to be the most useful.

2.3.2 Search Techniques

Internet is the place to find information about anything that we want or need. But there are billions of websites on the Intemet, and to find the specific information we want - quickly and easily is very complicated.

The best way to search the Internet is to take advantage of the power built into search engines (specialized websites such as Google.com, Yahoo.com, Bing.com or ask.com). Just enter words or phrases related to what you want to find, and the search engine will display a list of websites that include that information. Many times, the list shows a brief description of what's on each website, making it easier to decide which site to check out.

We can further narrow our search in several ways:

2.3.2.8 By Using Specific Keywords : Keywords are the terms that you use to find

content on the internet. Making keywords as specific as possible will help the search engine to track down the information that we want.

Say, for example, suppose that we want to find a local supplier that can supply bakery

items at home. If we type bakery items into our search engine, the results will include many pages about every type of bakery item, whereas typing bakery item supplier will return a more concise range of suppliers.

We can further refine our search by including other specific keywords. If we add our location, for example, we'll likely find someone local.

2.3.2.2 By Simplify Your Search Terms : Some engines include stop words in their

searches. These are frequently used words such as prepositions (in, of, on), conjunctions (and,but) and articles (a, the), which mean that we'll end up with more pages in search results than we need.

So, it's usually best to eliminate stop words from intemet searches.

Also, use the simplest form of the keywords that we're looking for, by avoiding plurals and verb forms with suffixes such as -ing, -s or -ed. For example, we would improve the quality of our search results by searching for service rather than services, or finance rather than financed or financing.

2.3.2.3 By Using Quotation Marks : Enclosing a search term within quotation marks

prompts the search engine to search for that specific word or phrase.

If the term is a single word, using quotation marks will cut out stemmed variations of it.For example, if you search for the word director, you'll likely receive a lot of results for direct,direction, directions, and so on, too. Typing “director” (with quotation marks), however, will ensure that you only get results for that stem word.

Note : Some search engines allow you to search for specific words by preceding them with the + symbol.

2.3.2.4 By Removing Unhelpful Words : Inserting a hyphen/small dash/minus sign

immediately before a word excludes it from a search.So imagine, for example, that we're looking to find out more about marketing. However,we want to concentrate on traditional marketing techniques, whereas the internet appears to be full of references to digital and social media marketing, all of which are appearing in our search.

Typing in marketing -digital will exclude digital from the search, making it easier for us to find the information we're looking for. Typing marketing digital -social would allow us to get more accurate information.

2.3.2.5 Search Using Operators : Wildcard Searches: use the * symbol as a placeholder

for another word. For example, searching for * man in the world retums results for the richest man in the world, the tallest, the oldest, and so on. Wildcard searches are also useful when, for example, we don't know the full text of a quote.

2.3.2.6 Combination Searches : The OR operator enables us to search for two or more terms simultaneously, and is most useful when those terms are very similar. Typing selling OR retailing, for example, will return pages where either of the terms is used, without both needing to be present.

Another way to combine searches is to use AND. This operator ensures that we receive

only search results that include two or more terms. For example, the search "Ambujas" AND

“Ambanis" would only deliver search results that includes the names of both companies.

2.3.2.7 Search a Specific Site : When we type site: followed by the URL of the website that we wish to search and a search term, we limit our search to a single website. So, site:www.pseb.ac.in "result" will retum all the pages from www.pseb.ac.in that feature the term "result"

2.3.2.8 Finding Related Sites : Another useful operator is related: Typing this in front of a web address that we already know - as in related:abc.com- our search results will deliver a range of websites that are similar to abc.com.

2.3.3 Image Search

Search by image is a feature by using we can check similar pictures and photos from the

internet. When we seerch with an image, our results may include:

Similar images

The websites that contain these images

We can do an image search on most browsers, like:Chrome, Firefox, and Safari etc.

To search by image, follow the steps given below:

¢ Qn your computer, open a web browser, like Chrome or Safari.

Go to Google Images.

Click Search by image. (2)

Click Upload an image > Choose file or Browse.

Select a picture from your computer.

Click Open or Choose.

2.3.4 News Search

We'll find the services to search for the latest news stories from hundreds of sources on the web. These services provide exceptionally good results for current event searching, because they crawl only news sites and revisit these sites several times per day. Thus, the results are usually focused and timely.

Google News

http://news.google.com/

Yahoo News

http:/(news.yahoo.com/

2.3.5 Map Search

Online map services can be used to get directions or search a given location. Google Maps is one of the most popular online map services.To find a location on Google Maps:

Type the address in the search field at the top of the page and click on Search Maps or

press Enter or Return on your keyboard.

2.4 INTERNET AND WORLD WIDE WEB

The Internet is a global network of networks while the Web, also referred formally as

World Wide Web (www) is collection of information which is accessed via the Internet.Another way to look at this difference is; the Internet is infrastructure while the Web is service on top of that infrastructure. Altematively, the Intemet can be viewed as a big book-store while the Web can be viewed as collection of books on that store.

The World Wide Web, or simply web, is a way of accessing information over the medium of the internet. It is an information-sharing model that is built on top of the intemet. The web uses the HTTP protocol, only one of the languages spoken over the intemet, to transmit data.The web also utilizes browsers, such as Internet Explorer or Firefox, to access Web documents called WebPages that are linked to each other via hyperlinks. Web documents also contain graphics, sounds, text and video.

The web is just one of the ways that information can be dispersed over the internet. The internet, not the web, is also used for email, which relies on SMTP, Usenet news groups,instant messaging and FTP. So, the web is just a portion of the Internet, but the two terms are not same.

2.5 INTERNET SECURITY

The internet offers a wealth of opportunities but it also brings its fair share of dangers too.Once you are online, it asks to remain security-aware at all times as there are many threats coming from multiple sources -

Hackers ; Hackers are people who attempt to break or avoid online security measures

for a number of reasons.

Viruses : Computer viruses are programs which are designed in order to gain entry

onto unsuspecting users’ computers. Once they have gained a grip within a computer

system they will then attempt to duplicate themselves before spreading via email,

networks and/or removable storage devices. Typically, their concern is to corrupt or

destroy data or otherwise damage the operation of the machine on which they reside.

Spyware : Spyware can prove to be a major annoyance as it's goal is usually to

collect personal information and browsing habits in order to deliver targeted advertising to us as we browse the web.

Worms : A worm is a self-replicating program which will attempt to spread itself

around your network, either via routers, the intemet or by email. Unlike a virus, a

worm does not need to attach itself to another program in order to spread.

Phishing : Phishing scams usually arrive via email and are designed to appear to be

from legitimate organisations so as to trick the recipient into responding with their

personal information.

Spamming : Spam is any form of unsolicited message, it will be on email, private

forum message. Spam messages don't usually pose any threat to your security but can

be incredibly annoying and distracting.

There are ways to protect from the threats:

Ensure that you are always running a fully updated anti-virus program Make sure that you have a firewall and that it is fully operational Choose secure and strong passwords and change them on a regular basis Install updates and patches for your operating system as soon as they become available Never click on links in emails unless you are 100% certain that they are trustworthyLastly, engage your brain and employ commonsense - it really is the best securitymeasure.
