About 21,000 young people in 17 American states do not attend classes in school buildings.

Instead, they receive their elementary(初等)and high school education by working at home on computers.The Center for Education Reform says the United States has 67 public “cyberschools.”and that is about twice as many as two years ago.

The money for students to attend a cyberschool comes from the governments of the states where they live. Some educators say cyberschools receive money that should support traditional public schools. They also say it is difficult to know if students are learning well.

Other educators praise this new form of education for letting students work at their own speed. These people say cyberschools help students who were unhappy or unsuccessful in traditional schools. They say learning at home by computer ends long bus rides for children who live far from school.

Whatever the judgement of cyberschools,they are getting more and more popular. For example, a new cyberschool called Commonwealth Connections Academy will take in students this fall. It will serve children in the state of Pennsylvania from ages five through thirteen.

Children get free equipment for their online education. This includes a computer,a printer,books and technical services. Parents and students talk with teachers by telephone or by sending emails through their computers when necessary.

Students at cyberschools usually do not know one another. But 56 such students who finished studies at Western Pennsylvania Cyber Charter School recently met for the first time. They were guests of honor at their graduation.

新型硬盘借口——串行ATA及UltraATA133
随着硬盘容量和速度的飞速增加,硬盘借口也经历了很多次革命性的改变,从最早的PIO模式到今天的串行ATA及UltraATA133,传输速率已经翻了几十倍。
随着硬盘内部传输率逐渐上升,外部借口也必须提高传输速率才不至于成为数据传输时的瓶颈,在这种环境下,串行ATA及UltraATA133规范诞生了。
串行ATA规范是计算机行业工作组(Computer Industry’s Working Group)制定的,它采用与并行ATA借口相同的传输协议,但硬件借口则不同,串行ATA借口的电压更低,而且数据线也更少。
UltraATA133是Maxtor公司提出的,是UltraATA100的后续规范,但它并没有得到ATA官方组织T13的正式认可,所以严格来说,UltraATA133应该算是企业规范而非行业规范,或许直接叫它“Fast Dirves”更为妥当。
由于串行ATA并不能向下兼容并行ATA设备,所以从并行ATA全面过渡到串行ATA要相当长的一段时间,在这期间,硬盘的发展速度不可能因此而停下来。而UltraATA133作为这一过渡期的折中解决方案,很可能成为最后一种并行ATA借口规范。
