As the Internet and computer use become more common, the need for security is more important than ever. According to the latest statistical analysis, it is estimated there are over 1.1 billion Internet users worldwide. The Internet provides diverse and useful resources such as Email, instant messaging, academic research, product research, paying bills, shopping, online banking, and the list goes on and on. For many of its 1.1 billion users the Internet is not just a tool but a way of life. But most users fail to take the time to research the risks involved. One of the greatest in the online world is computer hacking.
Computer hacking is the unauthorized access to a computer or network of computers. Hackers, those people who illegally enter systems, may alter or delete information, steal private information, or spread viruses that can damage or destroy files. But how exactly can a hacker get into a system to do these things?
Most hackers use information called protocols (协议) that are built into computer software. These protocols allow computers to interact with one another. Protocols are sort of like computer police officers(合法的). When a computer connects to another system, the protocols check to see if the access is valid. The protocols can also determine how much information can be shared between the two systems. Hackers can manipulate (操纵) the protocols to get unlimited access to a computer system. In fact, just the act of entering a computer network is considered hacking. This is commonly called passive hacking. Passive hackers get a rush from just being able to invade a challenging system like a bank or military network. Hackers that do damage to a system by releasing viruses or altering, deleting, or taking information are known as active hackers. They are, by far, the more dangerous of the two.
The easiest way to protect a system is with a good password. Long and unusual passwords, instead of your date of birth or telephone number, are harder for hackers to guess. For even greater security, some online services now use “password-plus” systems. In this case, users first put in a password and then put in a second code that changes after the user accesses the site. Users have special cards or devices that show them the new code to use the next time. So if a hacker steals the password, they won’t have the code. Or if the hacker somehow gets the code, they still don’t know the password.

In a society, such as the United States or Canada, which has many national, religious and cultural differences, people highly value individualism--the difference among people. Teachers place a lot of importance on the qualities that make each student special. The educational systems in these countries show these values. Students don't memorize information. Instead, they work individually and find answers themselves. There is often discussion in the classroom. At an early age, students learn to form their own ideas and opinions.
In most Asian societies, by contrast, people have the same language, history, and culture. Perhaps for this reason, the educational system in much of Asia reflects society’s belief in group goals and purposes rather than individualism. Children in China, Japan, and Korea often work together and help one another in assignments. In the classroom, the teaching methods are often very formal. The teacher lectures, and the students listen. There is not much discussion. Instead, the students recite rules of information that they have memorized.
There are advantages and disadvantages to both of these systems of education. For example, one advantage to the system in Japan is that there much more math and science than American students learn by the end of high school. They also study more hours each day and more days each year than North Americans do. The system is difficult, but it prepares students for a society that values discipline and self-control. There is, however, a disadvantage. Memorization is an important learning method in Japanese schools, yet many students say that after an exam, they forget much of the information that they have memorized.
The advantage of the educational system in North American, on the other hand, is that students learn to think for themselves. The system prepares them for a society that values creative ideas. There is, however, a disadvantage. When students graduate from high school, they haven’t memorized as many basic rules and facts as students in other countries have.

American public education has changed in recent years. One change is that increasing numbers of American parents and teachers are starting independent public schools called charter schools.
In 1991, there were no charter schools in the Unite States. Today, more than 2300 charter schools operate in 34 states and the District of Columbia. 575. 000 students attend these schools. The students are from 5 years of age through 18 or older.
A charter school is created by groups of parents, teachers and community members. It is similar in some ways to a traditional public school. It receives tax money to operate a number of students. The charter school must prove to local or state governments that its students are learning. These governments provide the school with the agreement, or charter that permits it to operate.
Unlike a traditional public school, however, the charter school does not have to obey most laws governing public schools. Local, state or federal governments cannot tell it what to teach.
Each school can choose its own goals and decide the ways it wants to reach those goals. Class sizes are usually smaller than in many traditional public schools. Many students and parents say teachers in charter schools can be more creative.
However, state education agencies, local education-governing committees and unions often oppose charter schools. They say these schools may receive money badly needed by traditional public schools. Experts say some charter schools are doing well while others are struggling.
Congress provided 200 million dollars for establishing charter schools in the 2006 federal budget. But, often the schools say they lack enough money for programs. Many also lack needed space, District officials say they have provided 14 former school buildings for charter education. Yet charter school supporters say officials should try harder to find more space.
