Thanks to expensive data fees, you might be tempted to log onto that free public Wi-Fi service while you're out and about.
“Think about the cost of being connected all the time. Nothing is free,” David Lee, a product manager for Norton, told CNBC. “” The Harvard Business Review agrees: “You're taking a risk every time you log on to a free network in a coffee shop, hotel lobby, or airport lounge.”
According to a survey by the company Symantic, 87 percent of U.S. consumers have used a public internet connection. And it was found that over 70 percent of them checked their personal email through public Wi-Fi, while 11 percent logged onto their online banking account.
No matter how safe the Wi-Fi connection seems to be, using it leaves your computer or smart phone easy to be attacked by hackers and data thieves. You don't really know who owns and monitors that router, nor who has access to the data that posses through it. Not to mention, hackers have dozens of ways to compromise public Wi-Fi accounts, from creating a network that appears legal to creating pop-ups that trick the user into downloading malware (恶意软件) onto their computers.
To protect yourself against hackers, experts say your best defense is a virtual private network (VPN), which encrypts (加密) your online activity. You can download your very own VPN through an app for Apple or Android devices, or by using the free encryption service CyberGhost But before you even start browsing, use this website to make a password that keeps you safe from hackers.
A. These are all of the tricks hackers use to hack your Internet security.
B. That can save you a lot of trouble.
C. The biggest threat is that your data and identity could be completely exposed.
D. Don't let convenience outweigh the consequences, though.
E. Setting up firewalls and antivirus software will also defend your computer against hackers.
F. Unfortunately, most people are unaware of the dangers.
G Hackers usually steal data in this way.

Ants: master cooperators
Millions of ants live together in a colony, but they don't compete, get confused, or become disorganized. They behave in an amazing orderly manner at all times. Some scientists refer to ants as 'super-organisms' because they live in such highly organized societies that work together to survive. The way ants live and work together has made them one of the most important creatures on the planet.
Ants, like bees, belong to a class of eusocial insects. Eusocial insects are broken into groups within their community, and each group has a special job to do depending on the needs of the community. There are three basic groups in an ant colony: queens, soldiers, and workers. Queens are the largest ants, and their only job is to reproduce—they lay all of the eggs that will eventually become soldiers and workers. Soldiers are responsible for protecting the colony and finding new places for nests. Worker ants have many jobs within the community, including caring for the eggs and young ants, hunting for food and maintaining the nest.
Some scientists are studying how ants can lead to a better understanding of labor issues, social class, and the use of nature resources in human communities. Ants have had millions of years of practice in working together to survive and grow. For a colony to function successfully, ants have to cooperate, from which people can learn a lot. Researchers hope that gathering information about how ants live together in communities can help people learn to cooperate and compromise with each other.
However, others argue that there are fundamental differences between ants and humans that mean human societies are unlikely ever to attain ant-like levels of collaboration. For example, ants in a colony don't compete with each other. When they are short of food in the colony, some worker ants automatically become 'feeder' ants and feed others with the food in their stomach, regardless of their usual job. When the food supply is replenished, they become worker ants again.
In addition, ants are able to work together without a leader giving them directions. Despite their names, queen ants are not leaders. Instead, ants find out what they need to do from their sense of smell. Research on harvester ants pass each other, they pick up a chemical smell which tells them what the other ant is doing. The number of ants they pass doing a particular job determines what they need to do. It is a form of communication, but unlike human communication it has no content; it is just based on numbers.
While ants undoubtedly have a great deal to teach us about organization and the structure of networks, those searching for a greater understanding of human behaviour and morals may need to look somewhere.
