macOS系统cores的简单介绍

文件夹和分区两者储存空间是什么关系

当今，分区的主要原因是让数据与系统分离，便于维护。

在FAT32时代，一方面分区不得超过32GB，此外还要考虑簇尺寸带来的空间浪费问题。

在NTFS时代，FAT32的种种问题已经不用考虑了。

由于Windows存在注册表等原因，这个理念在windows下不太明显，但在类unix系统下非常明显。

Linux很久没用了，以Mac为例。

系统文件集中在/bin、/cores、/mach_kernel这三个目录下。

个人文件集中在/Users目录下

程序集中在/Applications目录下。

分区后可将系统、数据、程序分到不同的分区上，任意一部分需要更新的时候，不会影响到其他部分。如果系统出了问题，那么格式化系统分区，恢复部分配置后，软件不用重装，用户数据依然存在。其他两个部分出现问题时类似。

这样的话，系统是迭代更新的，能够方便长久保存数据。

在Windows下，只能将程序与系统放在一起，将用户数据放在另一个地方。这样至少在重装系统的时候不必影响用户数据。但是由于Windows体系原因，程序是必须重装的。

-----以下是个人一直坚持并努力推行的Windows分区建议-----

由于NTFS文件系统使用率超过70~80%时，IO性能会下降，所以建议：

C盘：60GB-80GB，安装系统和全部软件、缓存。依据个人软件量的不同酌情调整。分区大小应当是最大使用空间的1.3倍。

D盘：硬盘剩余全部空间。用于存放各种用户数据。包括用户文件夹、桌面等应做重定向，移动到D盘以确保重装系统时不损失数据。

ps. 由于NTFS基本统一了簇大小，目前暂时可以认为无分区大小限制（实际是有的），所以以前的4个分区，一个分区系统一个分区游戏一个分区音乐再有个分区电影的分区方法，已经完全无意义了。

苹果笔记本电脑MacBookPro(MC373CH A)和MacBookAir(MC503CH A)的英文介绍

With faster processors and faster graphics, the new MacBook Pro does everything in nothing flat.The new 15- and 17-inch MacBook Pro. New Intel Core i5 and Core i7 processors. The new Intel Core i5 and Core i7 processors boost performance up to 50 percent over the previous generation. Based on Intel’s latest 32-nanometer process technology, these are the fastest dual-core processors available and they set an all-new benchmark for Mac notebooks.1Turbo Boost. Intel Core i5 and Core i7 processors also feature Turbo Boost. If you’re using processor-intensive applications like Aperture 3 or Final Cut Pro that would benefit from an extra performance kick, Turbo Boost dynamically increases the speed of one or both cores, taking a 2.66GHz MacBook Pro all the way up to 3.33GHz.Hyper-Threading. Built-in Hyper-Threading allows two threads to run simultaneously on each core, so Mac OS X recognizes four virtual cores instead of just two. When you’re running multiple applications at once, the Core i5 and Core i7 processors spread tasks more evenly across a greater number of cores — so you can get more done, faster.Integrated memory controller. Unlike systems that connect memory to the processor through a separate controller, the new MacBook Pro uses an integrated memory controller to connect memory directly to the processor. In a sense, this cuts out the middleman. With faster access to memory, each core gets right to work on your data, rather than waiting for it to arrive. Together with up to 4MB of shared L3 cache, the integrated memory controller ensures MacBook Pro can keep up with you.Next-generation graphics. Inside the 15- and 17-inch MacBook Pro models is the new NVIDIA GeForce GT 330M discrete graphics processor — the fastest graphics ever in a Mac notebook. With 48 processing cores and up to 512MB of dedicated video memory, this graphics processor delivers even more horsepower than the previous generation. And you don’t have to sacrifice efficiency for speed: The NVIDIA GeForce GT 330M is up to 30 percent more energy efficient than its predecessor. For even greater power savings, MacBook Pro also includes integrated Intel HD Graphics.Outstanding Performance Up to 1.5x faster than previous-generation MacBook Pro11.5x Final Cut Studio

HDV to H.264 encode1.4x Modo 401

3D rendering1.2x Motion 4.0.2

Playback and export speed1.1x Aperture 3.0.1

Common application tasksBaseline On-demand performance.

Off-the-charts efficiency. The 15- and 17-inch MacBook Pro models come standard with automatic graphics switching. It’s a breakthrough technology from Apple that switches graphics processors on the fly to give you performance when you need it (when you’re playing the latest 3D game, for example) and better battery efficiency when you don’t (such as when you’re reading email). MacBook Pro transfers the workload between the powerful discrete NVIDIA GeForce GT 330M graphics processor and integrated Intel HD Graphics so seamlessly, you won’t even notice. Whether you’re using applications like Aperture, Motion, or Final Cut Pro or just surfing the web, your MacBook Pro always knows which processor to use. You don’t have to log out, shut down, or change your preferences. Automatic graphics switching does it all for you.One charge. Nine hours. Since high-performance graphics kick in only when you need them, the battery in the 15- and 17-inch MacBook Pro can last up to 8-9 hours on a single charge.2The new 13-inch MacBook Pro. The new standard for performance and portability. The new 13-inch MacBook Pro features advanced NVIDIA integrated graphics technology along with Intel Core 2 Duo processors that are faster than ever before. That makes for the ultimate combination of performance, portability, and battery life — up to 10 hours — without adding an ounce to the slimmest, lightest MacBook Pro. And with 4GB of memory and larger hard drives now standard, this is the most powerful 13-inch MacBook Pro yet.Faster Intel Core 2 Duo processors. Now reaching speeds up to 2.66GHz, the new processors in the 13-inch MacBook Pro are big on performance. With the 1066MHz frontside bus and 3MB of shared L2 cache, all your applications will run faster and more efficiently than you thought possible.More powerful NVIDIA graphics. The 13-inch MacBook Pro features the new NVIDIA GeForce 320M integrated graphics processor with 48 processing cores — three times as many as before. The result? The fastest integrated graphics on the market and a performance boost of up to 80 percent over the previous generation.3 That makes a huge difference when you’re using 3D games and graphics-intensive applications. And when you’re not, you’ll benefit from a new energy-efficient architecture that uses up to 40 percent less power for everyday tasks like writing email and surfing the web. It’s so efficient, in fact, that you can now get up to 10 hours of battery life on a single charge.4One charge. Ten hours. The new energy-efficient architecture in the 13-inch MacBook Pro gives you up to 10 hours of battery life on a single charge.4 So you can stay unplugged longer than ever.13-inch MacBook Pro Graphics Performance Up to 1.8x faster than previous-generation 13-inch MacBook Pro31.8x Doom 3 1.6x Call of Duty 41.5x Unreal Tournament 20041.3x Quake 4Baseline See what makes each Mac different.Learn the basic differences between a PC and a Mac.The special one-day Apple shopping event.

苹果笔记本中的 /cores 里是什么文件？

你显示隐藏文件了，你可能下载了什么可以显示隐藏文件的程序了，show hidden files或者itool之类的

把那个程序再运行一次就行了

那就可能是预设有问题了

去下一个软件，隐藏起来，不然看上去很不爽

为什么都说苹果电脑好,苹果性能好,这么好那么好的??

苹果电脑的好处：

1、外观整洁大方，放在办公桌上不会有违和感。

2、苹果电脑采用的是mac os系统，基于unix系统开发，不会受到大部分病毒的感染。

3、苹果笔记本续航时间长，适合长时间户外办公。

苹果电脑的性能其实都是不错的。苹果是自己公司独立的系统，主要是安全，软件都是经过官方验证的安全软件，木马病毒很难侵入。

苹果系统软体 Mac OS X Lion 10.7.5 (11G56) 使用Winebottler转换win7系统下的ie浏览器出现错误。

是一定要用wine吗？其实如果想在OS X下运行windows程序，建议安装虚拟机。wine的效率并不高。而现在的vmware的效率基本上可以达到原生。
