对计算机Geek(美国俚语，意为技术鬼才)来说，帮女生选电脑绝对是既幸福又头疼的事。是个展示特长、讨好妹子的机会没错啦，但怎么把CPU、带宽、缓存等参数解释得通俗易懂呢？最近，果壳网友碧蓝怒火专门画了一组科普漫画，解决了这个Geek界的大难题。目前这组漫画已被微博转发1400多次，很多文科妹子表示：“解释非常到位，生平第一次看懂。”

To computer Geek(American slang,Meaning for technical genius)for,Help girls to choose the computer is absolutely both happiness and headache.Is a special show/Please sister chance that's right!,But how to CPU/bandwidth/Cache parameters explain it easy to understand it?recently,Fruit shell net friend anger special blue drew a set of popular science comic,To solve the problem of the Geek boundary.The cartoons have been micro bo forward more than 1400 times,A lot of liberal arts sister said:"Explain very in place,For the first time read."

　　漫画主角是电脑白痴妹子跟作者本人。妹子想买电脑，要求男生解释参数，但不准说得太复杂，凡是专业词一个不准用。作者接受挑战后，先用拟人和比喻手法解释了什么叫CPU核心、线程和频率。CPU核心，可以理解成在CPU里干活的小人，线程就像小人干活时用的电脑。最先都是单核心，就是一个小人在干活。为了让一个小人能同时干两件事，出现了HT超线程技术，也就是单核心双线程。这样还不够，于是有了更多小人，每个小人分两台电脑，这样就有了双核心双线程、四核心八线程等。至于频率，可以理解成他们干活的速度。

Cartoon character is a computer idiot sister with the author.Sister want to buy a computer,Request the boy interpretation parameters,But no said too complex,All professional word a no use.The author after accept the challenge,Use first personification and parable technique explains what is CPU core/Thread and frequency.CPU core,Can understand into the CPU working in SIMS,Thread as SIMS when working with computer.The first is single core,Is a person in the work.In order to make a dog can do two things at the same time,Appeared HT hyper-threading technology,Is the single core double thread.That's not enough,Then a more small,Each SIMS points two computers,So have the dual core double thread/Four core eight thread, etc.As for the frequency,Can understand into their work speed.

　　搞懂这些后，妹子又问什么叫一级二级三级缓存。作者画图解释，称内存就像一个仓库，CPU里的小人每接到一个指令就得到仓库取数据，由于仓库数据太多，找半天影响工作，于是造了个小仓库名叫缓存，先存点东西在缓存里，找起来也快。一开始只有一个小仓库，叫一级缓存，存储量有限不够放，于是又有了二级和三级缓存。也有可能翻遍三个小仓库（三级缓存）都找不到所需数据，这就叫“未命中”，这时只好请CPU小人去大仓库（内存），还找不到的话只能去硬盘中找了。

Understand these,My sister asked what call level 1 secondary level 3 buffer.The author drawing interpretation,Say memory is like a warehouse,The CPU buzzard each received a command get take data warehouse,Due to the warehouse data too much,For half a day to influence the work,Then made a small warehouse named cache,To put something in the cache,Find rise also fast.The beginning only a small warehouse,Call level cache,Storage co., LTD., put enough,So have secondary and tertiary cache.May also went through three little warehouse(Level 3 cache)All could not find required data,This is called"misses",Then have to please CPU dog go to large warehouse(memory),Still can't find words can only to find the hard disk.

　　内存宽带和频率呢？作者说，数据来往的通道就像一条高速公路，最开始是单行线，叫SDRAM，后来有了双车道叫DDR，数据奔跑起来更畅通。频率等于车速，如果SDRAM的速度是拖拉机的话，DDR的速度简直就是兰博基尼啊。

Memory broadband and frequency??The author says,Data flow of channel is like a highway,The beginning is one way street,SDRAM that,Then have a dual carriageway called DDR,Data run more clear.Frequency is equal to the speed,If SDRAM is the speed of the tractor words,DDR speed it is lamborghini ah.

　　这组漫画在微博发布后被网友热转。一位网友说，考了两次计算机等级考试都没搞懂的概念，看完漫画一下子豁然开朗。看来Geek们也得学点表达技巧啊。（扬子晚报记者 陈珊珊）

This group of comic in micro bo issued by net friend thermal transfer.A net friend say,Take an examination of the two computer grade examination didn't understand the concept,Watching cartoons suddenly be suddenly enlightened.It seems the Geek also have to learn some skills ah.(Yangzi evening news reporter ChenShanShan)
