Here are a few answers to common questions about how photo sharing websites work. For the sake of simplicity, we’ll work with the popular Flickr in these questions. These solutions should work with other photo sharing websites too.

Let’s start with privacy on photo sharing websites. Let’s say that you have photos on Flickr that you’re happy to share with the world.

But what you do when you have private family photos that you don’t want anyone seeing but a few close family members?

Certainly, you could mark sections of your Flickr account as private and for family only. The problem is, that anyone in the family that you wish to share the pictures with, needs to have an account of their own on Flickr too.

What if you just want to make things private but then show them to people you choose without requiring them to sign up for Flickr? Is this possible?

With Flickr’s Guest Pass option, you get to do exactly this. All you need to do is to create a Guest Pass and then send it to the person you wish to invite to see your pictures.

That person doesn’t have to sign up for a Flickr account to see anything on your account that you want them to see. To create a Guest Pass, all you need to do is to activate Share This Link on a certain set of photos that you’d like to share.

If there are any private photos and what you’ve selected, your Guest Pass option turns up on its own. You just fill in the e-mail addresses you want the pass to be sent to and it gets on its way. When you wish to take a Guest Pass away from someone, you just need to turn it off in your Guest Pass History page.

Everyone likes to know how popular they are. When it comes to photo sharing websites, they like to know what pictures of theirs have turned out to be the most popular. How do they find out which pictures these are?

On the Flickr photostream page, every photo, on its own preview, has a tag with this information. It shows you how many times it’s been viewed. If you just want your photos listed according to popularity, you just need to click on the link that says Popular at the top of the photostream page. There are all kinds of other ways in which you can have your pictures sorted as well. If you wish to see the ones with the most comments, you could.

What are certain upload restrictions that photo sharing websites impose on their users? On a basic and free Flickr account, you get to upload photos that get no larger than 10MB a picture; and you have a 100MB quota every month.

For a mere $25 a year, you could do whatever you wish. If you would like to upload an entire album on Flickr with as little handholding is possible, there are alternatives to using the Flickr website.

Flickr gives you a desktop uploader program that you install on your desktop. You just drag and drop photos into the icon and let it take care of everything.

What it means to use the phone is something that is certainly changing very quickly these days. It isn’t about a phone anymore. It’s all about Internet calling options. And those have players like FreePhone2Phone, Skype, Line2 Google Voice , Globe7 and Fring .

To anyone who isn’t really keeping up with where everything is, it can really get confusing. Let’s do a quick round-up of what Internet calling today offers.

First of all, while theoretically, you should be able to utilize your smartphone data plan to make free calls to all kinds of places, there isn’t any single app that lets you use your cell phone to make free calls everywhere.

What you can do is use your computer and a service like Skype or Google Voice to call any number or computer on earth. Or, you can use your smartphone, equipped with something like a Skype app to call other smart phones with the same app over the Internet for free but you can’t use them to call phone numbers for free.

Even so, the more you try calling over the Internet, from a computer or smartphone, the more you will realized that Internet calling is not really all that it is cracked up to be. To begin with, Internet calling means making do with crackly, distant and choppy voice quality. Read the rest of this entry →

There are families that for many reasons do not have a computer at home, or may have an older computer that is not able to access the internet.

They may feel that it does not matter, and that it does not negatively impact their lives, but if there are children in the family then the truth may be somewhat different.

The problem is quite simply that education institutions are coming to increasingly rely upon computers in order to get school work done. This may be as little as requiring that it is typed up for submission, or may be set assignments on particular software.

For instance the child may be required to use a word processing program in order to fix a section of text, or may have to make a spread sheet.

A great deal of research for school is also done via computer today, thanks to the internet. Research can take time-and between the research time and time taken to write up a document, this can often be too much time to do it in a library. Because of this, grades can suffer when there is no computer at home.

There is another problem-that of familiarity with computers. A child who is exposed to computers from an early age will find them easy to use. They will not be afraid of them, or nervous about breaking them.

Instead they will be willing to play around with a computer until they manage to get done what they need, and will be familiar enough that they should be able to find what programs and functions they need. Read the rest of this entry →

The present is a period that has high technology. Internet becomes part of the lifestyle. People are already familiar with sophisticated equipment, especially the Internet.

With the Internet so people will easily find the information and easy communication with many parties. Many people use the Internet as a medium to earn money and so forth.

The Internet that we use is the result of a great work and does not just happen. There is a process that should run when the Internet was developed. It is started from the discovery until the discovery of a primitive level with the top level.

In this paper, we will discuss a bit about the history of the world wide web. We’ve heard the name Ted nelson. Ted Nelson is the first inventor of the concept web.

Ted Nelson became an important part of the history of the world wide web. Ted Nelson is an instrumental in making the concept of hypertext. The concept of hypertext is a useful concept in the history of the world wide web.

By using this concept, then at this time there have been many applications that we can use the internet. In addition there is a scientist named Douglas Engelbert.

It gives scientists great work of development work to the concept of hypertext. With the great works created by Douglas Engelbert is created considerable innovation in the concept of hypertext.

Then came innovation back on the history of the world wide web in 1980. An informatics expert named Tim Berners-Lee and Robert Cailliau give their work to the world. They create a web for the first time during the history of the world wide web.

Nominally an inventor who came from europe. They are very excited to create something new in the history of the world wide web. With the discovery that they created the great work that the bias created directly spread across the globe.

Their discovery eventually became the inspiration for many people to create a browser or other types of Internet applications. That is the history of the world wide web.

This week has seen a great deal of controversy in the news regarding a website called WikiLeaks. In an effort to close down the website, a variety of tactics were used, including the removal of the website’s domain name by the registrar that held it.

Yet the website is still accessible-via the I.P. address instead. This may have raised the question for some people-what is the Domain Name System (DNS), and how does it affect the use of the internet?

All websites are hosted on a server, which is then connected to the world wide web. The problem is that even though it is connected, that doesn’t help it to be found by people wanting to view or use the site.

Just like with anything else, the best way of finding a website is to give it an address. This is the Internet Protocol (I.P.) address, and it is used as the unique identifier of the server that the website is hosted on.

The I.P. address points to the server though not the website, which needs to be further identified by the use of other symbols and file names.

The I.P. address is a string of numbers that are split into chunks. Like a house address, one would be the equivalent of the house number, the next the street, then the town and finally the country. By following the chunks from the highest level to the lowest, it is possible to find the server that the I.P. address refers to.

But the number is a problem when it comes to remembering. Humans on the whole are not good at remembering long strings of numbers that are seemingly meaningless, or random. But, we are good at remembering words and phrases. This is why the DNS was born. Read the rest of this entry →

There was a time when, after a person died, all that remained was memories, photographs, and occasionally some newspaper clippings.

For the average person, there wouldn’t be a whole lot more left once their life was over. But with the age of the internet things have changed drastically, and have

It’s hard enough to deal with the loss of a dearly loved person. There are things to be arranged-a funeral and wake-as well as potentially insurance policies to deal with, the will, distribution of the person’s effects. Nowadays there is a whole other element to deal with as well.

A person who spends a lot of time online may have multiple accounts that they regularly interact with. These may include email accounts, as well as accounts for the social networks, such as Facebook, Twitter and MySpace. These accounts can be a good way of letting distant friends know what has happened to your loved one,

Email accounts are the most common consideration as most internet users will have them. The policies vary greatly depending upon the company, with some handing your account over to your family, and others only deleting. Gmail for instance will give access, but Yahoo! refuses to and will only delete it. Read the rest of this entry →

When it comes to the use of the internet, there are many risks. There are viruses and spyware, and countless other varieties of malware.

But there are also chances that the websites that you visit may track your visit, your details, and perhaps use them in ways that you wouldn’t like them to. What information may be collected, and how do you protect yourself?

When you visit a web page there are a number of things that it can tell about you. There will be your I.P. address first and foremost, which will tell the site where you are, geographically. This can be used to serve up ads that are specific to your area.

They can also see which web page you were visiting before you reached them, and may be able to see what search terms you recently used, or even access your cookies using special snooping programs on the server.

Cookies are small files that are used to store information, such as encrypted versions of your usernames and passwords for the sites you visit (including your email and social networking sites). Read the rest of this entry →

Viruses and malicious code have been a major problem since the rise in popularity of the internet. A more recent, and growing problem are botnets, and the effect that they are having on cyber crime. Just what are botnets and who should be responsible for cleaning them up?

Botnets are a group of computers that have been compromised and that link themselves together to form a network.

The computers are compromised by malware, and are termed zombie computers. They do the work for the virus without any input from the owner of the computer.

These networks serve many purposes. They are normally used to generate money from the person who created the botnet, or they may be used to attack a website or a server.

Attacks such as these are called denial of service attacks, or DOS. They are intended to simply create havoc by stopping anyone else from using the server or website.

Spam is another function of these networks. Each computer in the botnet (and there may be thousands-even a million or more) sends just a small number of the spam emails in order to escape detection by the usual spam detection protocols. However, when a million computers send out a few spam emails-that’s a lot of spam that is sent out. Read the rest of this entry →

When the internet was first invented its users were few and far between. Worse-it was only the very technically minded who were able to use the internet, and so it remained a tool for a small number of people who were a part of the same circle.

Fast forward forty years and the vast majority of homes have internet access, or else people have access through universities or through their local library.

Others still have internet access thanks to their cell phone, allowing the use of email, social networks and letting them browse the web in order to find the information that they require. This is leading to a number of changes within our society-some of which are beneficial and others that are not.

It is easier than ever to keep in touch with friends and family around the world. Social networking sites allow people to find long lost friends. The net is incredibly cheap compared to overseas mail and phone calls. Read the rest of this entry →
