以什么与通信技术为核心英语作文

Intel酷睿i3、i5处理器相信大家都不会陌生，对于处理器中的诸如双核四线程或者四核八线程很多电脑爱好者都不知道什么意思。由于最近网友问的比较多，笔者今天为大家详解的介绍下什么是超线程。首先超线程我们主要讲得是针对Intel酷睿i3以及更高版本SNB处理器均已经采用超线程技术。那么什么是超线程呢？ 超线程是英特尔所研发的一种技术，于2002年发布。超线程的英文是HT技术，全名为Hyper-Threading，中文又名超线程。超线程技术原先只应用于Xeon服务器处理器当中，当时称为Super-Threading。之后陆续应用在Pentium 4以及当前主流的酷睿系列处理器中，随着技术的成熟，该技术已经应用于众多主流处理器当中。采用超线程即是可在同一时间里，应用程序可以使用芯片的不同部分。虽然单线程芯片每秒钟能够处理成千上万条指令，但是在任一时刻只能够对一条指令进行操作。而超线程技术可以使芯片同时进行多线程处理，使芯片性能得到提升。什么是超线程 超线程与普通线程对比 可能介绍了以上概念，很多电脑爱好者朋友还是不了解什么是超线程，其实大家可以这样理解：我们一般处理器有几个核心就有几个线程，像我们所熟悉的AMD众多处理器由于不支持超线程技术，所以当处理器是四核我们就知道其是四线程处理器，留心的朋友可能也会想到我们推荐的不少四核AMD配置中在介绍处理器时总会强调原生四核，其意思就是指真正的四核。那么对于Intel酷睿i3双核四线程处理器我们该如何理解呢？ 首先可以明确的是酷睿i3是双核心处理器，但为什么有四个线程呢？这就用到了Intel超线程技术，这其中涉及到了虚拟技术，理解虚拟主机的朋友或许可以很好理解，通过特定技术将双核心中的每个核芯模拟一个虚拟处理器出来，这就是超线程技术。如上图所演示的所示，目前超线程技术仅能达到虚拟核芯与物理合理相同的个数，如：酷睿i7为四核八线程，因此这个线程数量是与物理核心数量相一致的。 假如我们要想要购买一款拥有四核心的电脑，大家首先要搞清楚两个名词，一个是“物理四核”，另外一个是“虚拟四核”（格式化是什么意思 格式化与快速格式化区别）。这时如果参数中介绍的和我们是一款拥有物理四核处理器那么就可以放心购买。 以上详细为大家介绍了什么是超线程技术，相信大家都有一定的了解，可能大家还会有疑惑，超线程技术处理器性能如何呢？比如双核四线程处理器与原生四核处理器性能相同吗？答案是否定的，在参数等相当的情况下，当然是原生四核处理器性能更出色，超线程处理器性能低于物理四核处理器，但要高于普通双核未采用超线程技术双核处理器。 ●相似阅读：超频是什么意思 超频基本知识解读

Click the mouse and through the screen, you have information around the world at your finger It attributes the success to the rapid development of information With the popularity of information technology, it has great influence on our life, bringing us convenience and profound On one hand, one of the most obvious influences is the wild spread of That’s what we call the age of information With the help of information technology, we are capable of searching, transmitting and receiving sound, video, image, data, text and other information through It is like a large data base collecting all kinds of information around the world and therefore we can share all those Actually information technology plays as an extension of our eyes and ears, no matter from home or abroad, we can also be well- In other word, it enables us to know the world without stepping out of our On the other hand, information technology is changing our way for communication and problem In daily life we can chat with our friends online instead of walking out for meeting in If you get cameras, you can see each other’s face as well as hear both parties’ Without face-to-face and personal talking, we are still able to communicate with each other well and keep in Isn’t it convenient? As for work, some can just do it at home or anywhere, as long as they have computer and In this case, time will be more free to enjoy yourself and be with your When encountering problems, it no longer limits in a certain group of Since information technology has connected the whole world and made it a “global village”, it’s possible to put heads together and solve Especially when it comes to global problems such as concerning world Peace or human survival, information technology helps us to get involved into it, to discuss problems, collect opinions from different countries and different walks of people then finally find out the best From the discussion above, information technology is of great significance in our It exhibits the development and advance of human At the same time, this human’s achievement is influencing and changing our life day by What we need to do is to make good use of it and make contribution to the world, and of course to human 单击鼠标，通过屏幕,你在你的指尖有全世界的信息。它的成功归因于信息技术的快速发展。随着信息技术的普及,它有很大的影响对我们的生活,让我们方便而深刻的变化。一方面,一个最明显的影响是疯狂地传播信息。这就是我们所说的信息爆炸的时代。在信息技术的帮助下,我们能够搜索、传输和接收声音,视频,图像,通过计算机数据、文本和其他信息。它就像一个大型数据库收集世界各地的各种信息,因此我们可以共享这些资源。实际上信息技术来扩展我们的眼睛和耳朵,无论从国内还是国外,我们也可以消息互通的。换句话说,它使我们能没有走出我们的家了解世界。另一方面,信息技术正在改变我们的方式沟通和解决问题。在日常生活中我们可以在网上和朋友聊天,而不是走出去的会议的人。如果你有摄像头,你可以看到对方的脸和听到双方的声音。没有面对面的交谈和个人,我们仍然能够相互通信,保持联系。这不是方便吗?至于工作,有些可以在家里或任何地方做,只要有电脑和互联网了。在这种情况下,将能够更自由地享受你自己和你的家人时间。当遇到问题时,它不再限制在一个特定的一群人。因为信息技术连接整个世界,一个“地球村”,可以聚在一起商量并解决问题。尤其是对全球有关世界和平和人类生存等问题,信息技术帮助我们参与进去,讨论问题,收集意见来自不同国家和不同行业的人最后找到最好的解决方案。从上面的讨论中,信息技术在我们的生活中具有十分重要的意义。它展现了人类文明的发展和进步。同时,这个人类的成果是影响和改变我们的生活。我们需要做的是好好利用它,使对世界的贡献,当然,为人类自己做贡献。
