C/S模式和P2P模式的区别 ①：C/S结构是一种客户端/服务器结构，客户端与服务器之间是主从关系，是一种一对多的模式。它的信息和数据需要保存在服务器上，若用户要浏览和下载信息，必须先访问服务器，才能浏览和下载信息，而且客户机之间没有交互的能力。相反，P2P模式不分提供信息服务器和索取信息的客户端，每一台电脑都是信息的发布者和索取者，对等点之间能交互，无需使用服务器。 ②：C/S模式中信息的存储和管理比较集中、稳定，服务器只公布用户想公布的信息，并且会在服务器中稳定地保存一段时间，该服务器通常也不间断的运行在网络间。而P2P缺乏安全机制，P2P是能给用户带来方便，但也会带来大量垃圾信息，而且各个对等点可以随便进入或者退出网络，会造成网络的不稳定。 ③：从安全的角度来说，因为系统会出现漏洞，而C/S模式采用集中管理模式，客户端只能被动地从服务器获取信息，所以一旦客户端出了差错，并不会影响整个系统。 ④：C/S模式的管理软件更新的较快，要跟上技术，必须花费大量精力和金钱在软件的更新换代上，而且工作人员要维护服务器和数据库，也要耗费大量资金。相反的P2P不需要服务器，也就不必耗费大量资金，而且每个对等点都可以在网络上发布和分享信息，这使得闲散资源得以充分的利用。When you are old and grey and full of sleep, And nodding by the fire, take down this book, And slowly read, and dream of the soft look Your eyes had once, and of their shadows deep; How many loved your moments of glad grace, And loved your beauty with love false or true, But one man loved the pilgrim soul in you, And loved the sorrows of your changing face; And bending down beside the glowing bars, Murmur, a little sadly, how love fled And paced upon the mountains overhead And hid his face amid a crowd of stars. The furthest distance in the world Is not between life and death But when I stand in front of you Yet you don't know that I love you. The furthest distance in the world Is not when I stand in front of you Yet you can't see my love But when undoubtedly knowing the love from both Yet cannot be together. The furthest distance in the world Is not being apart while being in love But when I plainly cannot resist the yearning Yet pretending you have never been in my heart. The furthest distance in the world Is not struggling against the tides But using one's indifferent heart To dig an uncrossable river For the one who loves you. 本文来源：https://www.dywdw.cn/ba9ce618598102d276a20029bd64783e08127d74.html
