Pros and Cons of Networking网络的优缺点There is a wide variety of networks and their advantages and disadvantages mainly depend on the type of Advantages of Computer N Easy Communication and SpeedIt is very easy to communicate through a People can communicate efficiently using a network with a group of They can enjoy the benefit of emails， instant messaging， telephony， video conferencing， chat rooms， Ability to Share Files， Data and InformationThis is one of the major advantages of networking People can find and share information and data because of This is beneficial for large organizations to maintain their data in an organized manner and facilitate access for desired Sharing HardwareAnother important advantage of networking is the ability to share For an example， a printer can be shared among the users in a network so that there’s no need to have individual printers for each and every computer in the This will significantly reduce the cost of purchasing Sharing SoftwareUsers can share software within the network Networkable versions of software are available at considerable savings compared to individually licensed version of the same Therefore large companies can reduce the cost of buying software by networking their SecuritySensitive files and programs on a network can be password Then those files can only be accessed by the authorized This is another important advantage of networking when there are concerns about security Also each and every user has their own set of privileges to prevent them accessing restricted files and SpeedSharing and transferring files within networks is very rapid， depending on the type of This will save time while maintaining the integrity of Disadvantages of N Breakdowns and Possible Loss of ResourcesOne major disadvantage of networking is the breakdown of the whole network due to an issue of the Such breakdowns are frequent in networks causing losses of thousands of dollars each Therefore once established it is vital to maintain it properly to prevent such disastrous The worst scenario is such breakdowns may lead to loss of important data of the Expensive to BuildBuilding a network is a serious business in many occasions， especially for large scale Cables and other hardware are very pricey to buy and Security ThreatsSecurity threats are always problems with large There are hackers who are trying to steal valuable data of large companies for their own So it is necessary to take utmost care to facilitate the required security Bandwidth IssuesIn a network there are users who consume a lot more bandwidth than Because of this some other people may experience Although there are disadvantages to networking， it is a vital need in today’s People need to access the Internet， communicate and share information and they can’t live without Therefore engineers need to find alternatives and improved technologies to overcome issues associated with Therefore we can say that computer networking is always beneficial to have even if there are some 网络的种类繁多，其优势和劣势主要取决于网络的类型。网络的优势如下：1 网络使人容易沟通和快速通过网络进行交流很容易。人们可以通过与一群人的网络进行有效的交流。他们可以享受电子邮件、即时通讯、电话、视频会议、聊天室等的好处。3 可共享硬件联网的另一个重要优势是共享硬件的能力。例如，一个打印机可以在一个网络中的用户之间共享，这样就不必为公司中的每一台计算机都有单独的打印机。这将大大降低采购硬件的成本。4。共享软件用户可以轻松地在网络中共享软件。与同一软件的单独授权版本相比，软件的可联网版本在相当大的节省下可用。因此，大公司可以通过联网电脑来降低购买软件的成本。5。安全网络上敏感的文件和程序可以被密码保护。然后，这些文件只能被授权用户访问。当人们对安全问题感到担忧时，这是网络的另一个重要优势。此外，每个用户都有自己的权限集，以防止他们访问受限制的文件和程序。6。速度网络中共享和传输文件的速度非常快，这取决于网络的类型。这将节省时间，同时保持文件的完整性。网络的缺点1 工作故障和可能的资源损失由于服务器的问题，网络的一个主要缺点是整个网络的崩溃。这种故障在网络中经常造成每年数千美元的损失。因此，一旦建立起来，就必须正确地维护它，以防止这种灾难性的崩溃。最糟糕的情况是这样的故障会导致服务器的重要数据丢失。2。昂贵的建造在很多情况下，建立一个网络是一项严肃的业务，特别是对于大型组织来说。电缆和其他硬件的购买和更换非常昂贵。3 项目安全威胁安全威胁一直是大型网络的问题。有黑客试图窃取大公司的有价值的数据，以获取他们自己的利益。因此，有必要采取最大的措施，以方便采取必要的安全措施。4。带宽问题在网络中，用户比其他人消耗更多的带宽。因为其他一些人可能会遇到困难。虽然网络也有缺点，但在当今的环境中，这是一个至关重要的需求。人们需要访问互联网，交流和共享信息，没有这些信息他们就无法生活。因此，工程师需要找到替代和改进的技术来克服与网络相关的问题。因此，我们可以说，即使有一些缺点，计算机网络也总是有益的。
写作思路：写出网购的优点和缺点，对于优点和缺点，分开举例说明。正文：With the development of the Internet and the popularization of computers，shopping on the Internet has become a commonplace in our 译文：随着互联网的发展和计算机的普及，网上购物已经成为我们生活中的一个普遍的问题。Here consumers can buy almost everything they 译文：在这里，消费者可以买到他们所需要的一切。Shopping on the Internet has a lot of advantages， of which the most important is perhaps its 译文：网上购物有很多好处，其中最重要的也许是它的方便。People don't have to waste a lot of their energy and precious time to go from one shop to another to choose the commodities they 译文：人们不必浪费大量的精力和宝贵的时间去从一个商店到另一个选择他们喜欢的商品。This is especially desirable to the old， the sick and the busy people who cannot go to the shops in 译文：这对于那些不能亲自去商店的老人、病人和忙碌的人来说尤其可取。The goods come in all shapes， sizes and colors on the I译文：这些货物在网上的各种形状，大小和颜色都有。All they need to do is to sit in front of their computers and click the 译文：所有他们需要做的是坐在电脑前点击鼠标。The commodities they order will be delivered to them 译文：他们所订购的商品将及时送到他们的。However， shopping on the Internet also has its 译文：然而，在互联网上购物也有其缺点。The first disadvantage is that the consumers can't see the goods or try them on 译文：第一个缺点是消费者看不到商品或者亲自试用。Sometimes， the real goods may not be the same as what they have seen on the 译文：有时候，真正的商品可能不一样，因为他们在电脑上看到的。The second disadvantage is that some shops on the Internet are not 译文：其次是一些商店在网上没有注册。They will never deliver anything to you after they get the money from 译文：在他们从你得到的钱之后，他们永远不会给你提供任何东西。Once cheated， you will find that you have nowhere to go to 译文：一旦被欺骗，你会发现你无处可去抱怨。
