發(fā)布時(shí)間:2017-12-30 22:49:36網(wǎng)絡(luò)謠言Direction:For this part, you are allowed 30 minutes to write a short essay based on the picture below. You should focus on the harm caused by misleading information online. You are required to write at least150 words but no more than 200 words參考范文:(描述圖畫)This is a simple but thought-provoking drawing. As we can see in it, a meeting seems to be going on, with several staff members sitting around a table and a laptop in front of each of them. A leader-like man stands there, complaining: We have lots of information technology. We just don t have much useful information.(點(diǎn)明寓意)Simple as the picture is, the message it conveys is profound. Evidently it is meant to reveal the fact that there is too much junk information online. (舉例論證)Taking a look around, we can also find examples too many to enumerate. The best illustration that I can recall here and now is the fact that whenever you search for the cure for a disease or a scenic spot to visit, you are flooded by advertisements, many of which are even cheating. (分析影響)Actually, the problem has become so widespread that it has severely affected people s life and hindered the development of society.(提出建議)Of course, we should not give up eating for fear of being choked. Admittedly ,information technology has greatly facilitated our life and work. The best policy, as I see it, is to maximize its advantages and eliminate its unhealthy influence .For one thing, itis imperative that pertinent laws and regulations be worked out and rigidly enforced to punish those spreading cheating ads online. For another, the searching engine websites should make a point of reducing junk information. Only with these measures taken can we expect the solution of the problem.

2017公共基礎(chǔ)知識(shí)計(jì)算機(jī):網(wǎng)絡(luò)協(xié)議-解放軍文職人員招聘-軍隊(duì)文職考試-紅師教育

一、網(wǎng)絡(luò)協(xié)議的概述網(wǎng)絡(luò)協(xié)議指網(wǎng)絡(luò)協(xié)議為計(jì)算機(jī)網(wǎng)絡(luò)中進(jìn)行數(shù)據(jù)交換而建立的規(guī)則、標(biāo)準(zhǔn)或約定的集合。網(wǎng)絡(luò)有許多互相連接的接點(diǎn),在這些接點(diǎn)之間要不斷的進(jìn)行數(shù)據(jù)交換,要做到有序的交換數(shù)據(jù),每個(gè)接點(diǎn)就必須遵守一些事先約定好的規(guī)則,這些規(guī)則明確規(guī)定了所交換的數(shù)據(jù)的格式以及相關(guān)的同步問題。二、網(wǎng)絡(luò)協(xié)議的三要素1.語(yǔ)義:是解釋控制信息每個(gè)部分的意義。它規(guī)定了需要發(fā)出何種控制信息,以及完成的動(dòng)作與做出什么樣的響應(yīng)。2.語(yǔ)法:是用戶數(shù)據(jù)與控制信息的結(jié)構(gòu)與格式,以及數(shù)據(jù)出現(xiàn)的順序。3.時(shí)序:是對(duì)事件發(fā)生順序的詳細(xì)說(shuō)明。也可稱為 同步 。二、網(wǎng)絡(luò)協(xié)議的層次結(jié)構(gòu)由于網(wǎng)絡(luò)節(jié)點(diǎn)之間聯(lián)系的復(fù)雜性,在制定協(xié)議時(shí),通常把復(fù)雜成分分解成一些簡(jiǎn)單成分,然后再將它們復(fù)合起來(lái)。最常用的復(fù)合技術(shù)就是層次方式,網(wǎng)絡(luò)協(xié)議的層次結(jié)構(gòu)如下:1.結(jié)構(gòu)中的每一層都規(guī)定有明確的服務(wù)及接口標(biāo)準(zhǔn)。2.把用戶的應(yīng)用程序作為最高層。3.除了最高層外,中間的每一層都向上一層提供服務(wù),同時(shí)又是下一層的用戶。4.把物理通信線路作為最低層,它使用從最高層傳送來(lái)的參數(shù),是提供服務(wù)的基礎(chǔ)。
