黑客一词来自英语原意是指哪种电脑用户

黑客最早源自英文hacker，早期在美国的电脑界是带有褒义的。但在媒体报导中，黑客一词往往指那些“软件骇客”(software cracker)。黑客一词，原指热心于计算机技术，水平高超的电脑专家，尤其是程序设计人员。但到了今天，黑客一词已被用于泛指那些专门利用电脑网络搞破坏或恶作剧的家伙。对这些人的正确英文叫法是Cracker，有人翻译成“骇客”。

热衷研究、撰写程序的专才，精通各种计算机语言和系统，且必须具备乐于追根究底、穷究问题的特质。“黑客”一词是由英语Hacker音译出来的，是指专门研究、发现计算机和网络漏洞的计算机爱好者。他们伴随着计算机和网络的发展而产生成长。黑客对计算机有着狂热的兴趣和执着的追求，他们不断地研究计算机和网络知识，发现计算机和网络中存在的漏洞，喜欢挑战高难度的网络系统并从中找到漏洞，然后向管理员提出解决和修补漏洞的方法。

The Telephone

The telephone is one of the most welcome and useful inventions. No wonder more and more families have got to use their own telephones today.

The telephone makes things easy in many ways. Especially, after the mobile telephone appears, communication becomes easier and rapider.

Thus they will get comfort whenever they are homesick or they run into trouble. With the help of the telephone, people can keep in touch with anyone at any time and in any place for urgent help.

All in all, the telephone is so helpful that we can say that nowadays we can not live without the telephone in our daily life. We will further improve the performance of the telephone so as to create better conditions for its development.

电话

电话是目前最受欢迎和最有用的发明之一,怪不得越来越多的人已经使用了自己的电话.

电话在许多方面使事情变得简单,尤其是在移动电话出现以后,通讯变得更加快捷方便.对于那些离家的学生和做生意的人来说,电话缩短了同家人的距离,在此它能蛤想家的人和处在困难中的人一个好的心情.有了电话帮助,人们可以随时随地和任何人联系,寻求紧急帮助.在这种情况下,电话显得尤其重要.

总之,电话是如此有用,以至于如今的日常生活离不开它.我们逐步提高电话功能,为它的发展创造更好的条件.

In 1640s, the first mechanical calculator was manufactured for commercial purposes. Blaise Pascal invented the first commercial calculator, which was a hand-powered adding machine. In 1670s, Gottfried Liebnitz made attempts to invent a calculator that multiplied mechanically, but the first multiplying calculator appeared in Germany just before the American Revolution. This was a gigantic step taken in the world of computing that laid the foundation for inventing computers. In the year 1801, Joseph-Marie Jacquard, Frenchman, built a loom that weaved by reading the punched holes on sheets of hardwood. This loom was created almost 140 years before the computer was invented.

Right after the first commercially manufactured calculator in the year 1820, Charles Babbage began his quest to develop a machine that was used for programming. The first programmer, Ada Lovelace used the machine invented by Babbage to mechanically translate a short written work. A decade later, a professor of mathematics named George Boole, came out with ‘An Investigation of the Laws of Thought’, and is considered as the Father of Computing Science. In 1890, the census was tabulated on punch cards on a system that used electric power. This was developed by Herman Hollerith of MIT.

Prior to this invention, the first printing calculator was introduced in the year 1892 by William Burroughs. Though the first model was hand-powered, an electronic one was introduced soon after. Unaware of the work of Charles Babbage, Vannevar Bush of MIT also built a device, which he named as differential analyzer. Though it can handle simple calculus problems, accuracy was still not upto the mark. It was then that problems arose as to who invented their device first. Due to poor record keeping and documentation of inventions, one could not really decide which device was invented when.

During the year 1935, a German construction engineer named Konrad Zuse develops a mechanical calculator to handle math and calculations in his profession. He then started developing a programmable electronic device and finished it in 1938. In the year 1936, John Vincent Atanasoff started working on developing a digital computer in a campus in Iowa. It was designed to solve linear equations that were much common in physics. However, he left his job for a new offer in Washington.

In the year 1937, the Germans developed a complex mechanical encoder named the Enigma and believed it to be unbreakable. Alan Turing proposed the idea of developing a Universal Machine, which would be capable of computing any algorithm. In this year itself, George Steblitz created his machine named Model K(itchen), which was an accumulation of otherwise ineffective and leftover material, in order to solve complex calculations. The design was improved while he was working at Bell Labs and on September 11, 1940, he used the teletype machine to transmit a problem from New Hampshire to his Complex Number Calculator in New York. The problem was met with success and this was the first example of a network.

The Enigma was broken by a machine called Colossus Mark I in Poland and then in Britain and US. After this, computers were built that could break not just German but Japanese codes as well. Then came the creation of integrated circuit technology and microprocessors, which decreased the size and cost of computers. The personal computer or PC was created in the 1980s and with the advent of the internet shortly after, computers slowly became essential part of urban households

在17世纪40年代，第一台机械计算机（一开始“计算机”不叫“Computer”，而是叫“计算器”（calculator）。）由于商业目的被造出来了。Blaise Pascal发明了第一台出于商业目的的计算机，属于手动的算术计算机。在17世纪70年代，Gottfried Liebnitz这个人尝试制造一种乘法计算机（我不知道这个现在应该怎么叫，偶又不是学计算机的。）但是这种计算机真正诞生还是在德国，而且在美国独立战争爆发之前。这是人类计算机史上巨大一次跨越，也为后面计算机的发明奠定了基础。在1801年， Joseph-Marie Jacquard（约瑟夫·玛丽·杰卡德）,，这法国人设计的雅卡尔提花织机可以靠读取硬木板上的穿孔来纺织。这种纺织机出世早于计算机差不多140年。

真的好长哦，你自己看嘛，就是名字有点多，句子这么简单，我不想再写了。
