The Internet is a giant network of computers located all over the world that communicate with each other. The Internet is an international collection of computer networks` that all understand a standard system of addresses and commands, connected together through backbone systems. It was started in 1969, when the U.S. Department of Defence established a nationwide network to connect a handful of universities and contractors. The original idea was to increase computing capacity that could be shared by users in many locations and to find out what it would take for computer networks to survive a nuclear war or other disaster by providing multiple path between users. People on the ARPNET (as this nationwide network was originally called) quickly discovered that they could exchange messages and conduct electronic "conferences" with distant colleagues for purposes that had nothing to do with the military industrial complex. If somebody else had something interesting stored on their computer, it was a simple matter to obtain a copy (assuming the owner did not protect it). Over the years, additional networks joined which added access to more and more computers. The first international connections, to Norway and England, were added in 1973. Today thousands of networks and millions of computers are connected to the Internet. It is growing so quickly that nobody can say exactly how many users "On the Net". The Internet is the largest repository of information which can provide very very large network [参考译文] Internet是由位于世界各地相互通信的计算机连接而成的巨大的计算机网络。 Internet是计算机网络的国际性的集合,这些网络都符合具有地址和命令的标准体系,并经骨干网连在一起。Internet始建于1969年,当时美国国防部为连接少数几所大学和协议企业而建立了一个全国性网络。最初的想法是要增加计算机能力并可由许多地点的用户共享,并且通过提供用户间多条路径来找到哪一种计算机网络能够在核战或其他灾难中幸存。ARPNET(这种全国网络最初的名称)上的用户很快就发现他们可以与远距离的同事交换消息,并且进行某种目的的电子“会议”,而这些目的与军事工业企业没有任何关系。如果另外一些人在其计算机中存有有趣的东西,得到其拷贝是很容易的事(假定拥有者没有进行保护)。 几年间,新的网络接入使越来越多的计算机加入进来。在1973年进行了第一次与挪威和英国的国际连接。今天,有成千上万的计算机网络和数百万台计算机与Internet相连。Internet发展如此之快以至于没有人能准确地说出网上有多少用户。 Internet是最大的信息宝库,它可以提供非常巨大的网络资源。这种网络资源可分为网络设备资源和网络信息资源。网络设备资源使我们能够进行远程计算和通信。网络信息资源向我们提供各种各样的信息服务,如科学、教育、商务、历史、法律、艺术和娱乐等等。
Does Technology Reduce Social Isolation?
Hundreds of daily updates come from friends on Facebook and Twitter, but do people actually feel closer to each other?
每天在Facebook和Twitter上都有朋友们数以百计的更新,但实际生活中人们是否感觉彼此更亲近呢?
It turns out the size of the average American’s social circle is smaller today than 20 years ago, as measured by the number of self-reported confidants in a person’s life. Yet contrary to popular opinion, use of cellphones and the Internet is not to blame, according to a new study released Wednesday by the Pew Internet and American Life Project.
根据互联网与美国生活专案周三发布的一项最新调查,在计算过美国人日常生活中自己认为的密友知己的数量后,事实证明当代美国人社交圈子的平均人数比他们20年前要小。但是与当前流行的观点所不同的是,这并不归罪于手机的使用和网络的普及。
In fact, people who regularly use digital technologies are more social than the average American and more likely to visit parks and cafes, or volunteer for local organizations, according to the study, which was based on telephone interviews with a national sample of 2,512 adults living in the continental United States.
根据一项调查表明,事实上经常使用数字技术的人比普通的美国人更具社交性,而且也更多的游览公园,光顾咖啡馆或更多的参加当地的志愿者活动。该项调查通过电话采访了美国本土大陆的2512名成年人。
The study found some less-than-social behavior, however. People who use social networks like Facebook or Linkedin are 30 percent less likely to know their neighbors and 26 percent less likely to provide them companionship.
这项调查也发现了一些不太符合社交性的习惯的行为,那就是,经常使用社交网站Facebook和Linkedin的人不太喜欢去认识他们的邻居,有26%的不喜欢和邻居交往。
The circle of close friends for mobile phone users tends to be 12 percent larger than for nonusers. People who share online photos or instant messages have 9 percent larger social circles than nonusers.
经常使用手机的人,他们的好朋友圈子比不使用手机者常常要多12%,在网上分享自己的照片和及时信息的人,他们的好朋友圈子比不使用者常常要多9%.
The study also found that people still prefer face-to-face communication as the primary means to stay in touch with friends and family (people see loved ones in person an average of 210 days a year). Respondents said that they were in touch via mobile phone an average of 195 days a year.
这项调查也发现人们更喜欢面对面的沟通,这是他们和好友和家庭成员保持联系的最重要的方式(人们一年中有210天会亲自看自己的亲人)。被调查者说他们一年中平均有195天通过手机和他们联系。
