Whatisit?Internet：

因特網(wǎng)。泛指由多個(gè)計(jì)算機(jī)網(wǎng)絡(luò)相互連接而成的一個(gè)網(wǎng)絡(luò)，它是在功能和邏輯上組成的一個(gè)大型網(wǎng)絡(luò)。采用TCP/IP協(xié)議。因特網(wǎng)，源自英文的Internet，它的含義從廣義上來說就是是“聯(lián)接網(wǎng)絡(luò)的網(wǎng)絡(luò)”。這種將計(jì)算機(jī)網(wǎng)絡(luò)互相聯(lián)接在一起的方法稱為網(wǎng)絡(luò)互聯(lián)。作為專有名詞，它所指的是全球公有、使用TCP/IP這套通訊協(xié)議的一個(gè)計(jì)算機(jī)系統(tǒng)，這個(gè)系統(tǒng)所提供的信息與服務(wù)，以及系統(tǒng)的用戶。因此，世界上這個(gè)最大的互聯(lián)網(wǎng)絡(luò)也被簡稱為“互聯(lián)網(wǎng)”(theInternet)。經(jīng)過多年的發(fā)展，互聯(lián)網(wǎng)已經(jīng)在社會(huì)的各個(gè)層面為全人類提供便利。電子郵件，即時(shí)消息，網(wǎng)上購物等等內(nèi)容已經(jīng)成為越來越多人的一種生活方式；而基于B2B，B2C等平臺(tái)的電子商務(wù)，跨越洲際的商務(wù)會(huì)談以及電子政務(wù)等等為商業(yè)與政府辦公創(chuàng)造了更加安全，更加便捷的手段。Read1aandanswerthequestion.WhatcanwedoontheInternet?We
