IT英语新词集锦

　　A scientific research area devoted to the creation and study of computer simulations of living organisms .Computer viruses have forced a renewal of the debate on the definition of life .Besides forcing us to re-examine our definition of life ,artificial life research may create more effective technology .By applying artificial life concepts to real-life problems ,we can program computer-generated solutions to compete for survival based on their capability to perform a desired task well.

　　人工生命

　　致力于建立和研究计算机模拟生命组织(有机体)的一种科研领域。计算机病毒已迫使关于生命定义的辩论重新展开。除了迫使我们重新检查生命定义之外,人工生命研究可能会创造更有效的技术。通过将人工生命概念应用于现实生活问题,我们可以对计算机生成的解决方案编程,以在其有能力很好地完成所要求任务的基础上为生存而竞争。

　　Firewalking

　　A technique for testing the vulnerability of a firewall and mapping the routers of a.network that sits behind a firewall. Firewalking is a method of disguising port scans. In practical applications, firewalking is similar to tracerouting and works by sending into the firewall TCP or UDP packets that have a TTL set at one hop greater than the targeted firewall. If the packet makes it through the gateway, it is forwarded to the next hop where the TTL equals zero and elicits a TTL “exceeded in transit” message, at which point the packet is discarded. Using this method, aclearcase/" target="_blank" >ccess information on the firewall can be determined if successive probe packets are sent.

　　防火墙

　　一项测试防火墙弱点和绘制防火墙后面网络上的路由器分布的技术。趟火墙是一种伪装端口扫描的方法。在实际应用中，趟火墙与路由跟踪技术类似，工作时把一跳的生存时间字段设定大于目标防火墙的 TCP或UDP包送进防火墙。如果该包通过了网关，它就转到下一跳，这时生存时间为零并得出生存时间“传输超时”的信息，在此情况下该包被废弃。利用此法，如果发送连续的探测包，就能确定防火墙上的接入信息。
注册近似域名

　　Typosquatting

　　slang. Registering a domain name that is a variation on a popular domain name with the expectation that the site will get traffic off of the popular site because of a user's misspelling of the name. For example, registering the domain names sino.com or yahooo.com in the hopes that someone making a typo will get to that site unexpectedly.

　　注册近似域名

　　（俚语）注册流行域名的变种，希望如果用户把该流行网站的名字拼错时，能从该流行网站拉些流量过来。例如，注册 sino.com或yahooo.com域名，希望有人打字出错而意想不到地进入这些网站。
