The Internet and Telecommunications教案(通用4篇)The Internet and Telecommunications 篇1the internet and telecommunications教案module 6 the internet and telecommunications话题导入电脑网络是我们日常生活中的重要工具,如果没有了它,这个世界不知会变得如何?电脑网络能处理的事情太多了,衣、食、住、行、吃、喝、玩、乐、电子采购、电子公文交换、电子支付、电子保健、电子监理等等,都和电脑脱不了关系,它还能把事情整理得井井有条。
在以后的岁月中,不懂电脑网络的人很可能寸步难行!背景知识the first computer世界上第一台电子数字式计算机于1946年2月15日在美国宾夕法尼亚大学正式投入运行,它的名称叫eniac(埃尼阿克),是电子数值积分计算机(the electronic numberical integrator and computer)的缩写。
它使用了17468个真空电子管,耗电174千瓦,占地170平方米,重达30吨,每秒钟可进行5000次加法运算。
虽然它的功能还比不上今天最普通的一台微型计算机,但在当时它已是运算速度的绝对冠军,并且其运算的精确度和准确度也是史无前例的。
computer network将地理位置分散的计算机通过专用的电缆或通信线路互相连接,就组成了计算机网络。
网络可以使分散的各种资源得到共享,使计算机的实际效用提高了很多。
计算机联网不再是可有可无的事,而是计算机应用中一个很重要的部分。
人们常说的因特网(internet,也译为国际互联网)就是一个通过通信线路连接、覆盖全球的计算机网络。
通过因特网,人们足不出户就可获取大量的信息,与世界各地的亲友快捷通信, 进行网上贸易等等。

万维网互联网因特网之间的区别

万维网互联网因特网之间的区别互联网、万维网、因特网,这些名词经常被我们提到,但是很少有人能够准确地说出它们之间的区别。
实际上,它们虽然相关联,但却是不同的概念。
下面本文将对它们进行具体的解释和分析。
一、互联网互联网(Internet),又称为全球计算机网络,是连接全球各个计算机网络的网络系统。
最初的互联网诞生于20世纪60年代末期,当时的目的是为了实现研究和教育机构之间的信息共享。
通过互联网,用户可以利用各种应用程序(如网络浏览器、电子邮件、即时通讯等)进行在线交流、信息检索、数据传输等操作。
互联网的发展对人类社会产生了重大影响,它已经逐渐成为人们生活和工作中不可或缺的一部分。
二、万维网万维网(World Wide Web),简称WWW,是互联网上最广泛使用的一种服务。
万维网始于1989年,由英国人蒂姆·伯纳斯-李提出。
它是一个基于超文本交互方式,通过网络链接可以在全球范围内进行信息共享和传播。
万维网的基本单位是网页,网页上可以包含文字、图片、音频、视频等各种类型的媒体。
用户可以通过浏览器访问网页,通过超链接浏览网页间的关系,打开各种网站、博客、新闻等。
三、因特网虽然互联网和万维网都是我们日常生活中经常使用的网络服务,但事实上,互联网只是一个较为抽象的概念,而万维网只是互联网上的一种服务。
而因特网(Internet)则是一种广泛使用的计算机网络,它是由国际互联网协会会议(IAB)所管理。
因特网是一种全球性的计算机网络,是由各种不同类型的计算机网络所构成。
这些网络可以是公共的,也可以是私有的,可以是局域网,也可以涉及到广域网。
互联网和万维网均是因特网的一部分。
综上所述,互联网、万维网和因特网之间的关系可以用一个套娃的形象来比喻。
因特网是套娃的最外层,万维网是套娃的第二层,互联网是套娃的内部网络。
虽然它们都是计算机网络的一种,但是它们的本质和作用是不同的。
了解它们之间的区别,可以帮助我们更好地理解和使用这些网络服务,对我们日常生活和工作有积极意义。
