询问操作方法：数据延迟和游戏，笔记本电脑的屏幕作为第二显示器，以及标识计算机的组件

You’ve got questions and we’ve got answers. This week we take a look at data latency while playing computer games, how to use your laptop screen as a secondary monitor, and how to easily list and ID the components in your Windows machine.

您有问题，我们有答案。 本周，我们来看看玩电脑游戏时的数据延迟，如何将笔记本电脑的屏幕用作辅助显示器以及如何轻松列出和标识Windows计算机中的组件。

了解数据延迟和游戏 (Understanding Data Latency and Gaming)

()

Dear How-To Geek,

亲爱的How-To Geek，

My daughter loves a game called Runescape (which I use to blackmail her into getting her homework done).  She plays this game on a dial-up account because she says the Wildblue satellite internet account has a big lag to it.   I have sort of verified this by watching when she clicks on the screen and watched her Runescape character move when she connects on dial-up and Wildblue.  Wildblue is definitely slower.  Yet, when we download on dial-up, dial-up is insanely slower.

我女儿喜欢一个叫做Runescape的游戏(我用来勒索她完成家庭作业)。 她说该游戏使用拨号帐户，因为她说Wildblue卫星互联网帐户有很大的滞后性。 通过观察她在屏幕上单击时的观看情况以及在她通过拨号和Wildblue连接时观看她的Runescape角色移动的情况，我对此进行了某种程度的验证。 Wildblue肯定慢一些。 但是，当我们通过拨号下载时，拨号速度异常慢。

This doesn’t make sense to me.  How can satellite internet be so much faster downloading than dial-up, but yet be so much slower when playing a game on it?

这对我来说没有意义。 卫星互联网的下载速度如何比拨号上网快得多，而在互联网上玩游戏却慢得多呢？

Sincerely,

真诚的

Watching Lag in Wisconsin

在威斯康星州看滞

Dear Watching,

亲爱的观看，

What’s going on is this: there’s a big difference between total bandwidth (the amount of data you can download at a time), and latency (how fast each back and forth happens). Satellite internet is notorious for very long latency, but obviously can transfer a lot of data (like all your TV channels).

这是怎么回事：总带宽(一次可以下载的数据量)和延迟(每次来回发生的速度)之间有很大的差异。 卫星互联网因长时间延迟而臭名昭著，但显然可以传输大量数据(例如您的所有电视频道)。

Imagine it like this: if you lived in a big city, you can hire a bike-messenger courier (low latency) to very quickly deliver letters and small packages from one place to another. Alternatively, you could hire a big truck (high bandwidth) to carry larger loads—but it would take a lot longer to load up the truck and make your way through traffic. That’s the difference between latency and total bandwidth.

可以这样想象：如果您住在大城市，则可以租用自行车信使快递员(低延迟)，以快速将信件和小包裹从一个地方递送到另一个地方。 另外，您可以租用一辆大卡车(高带宽)来承载更大的货物，但是装载卡车并通过交通要花费更长的时间。 那就是延迟和总带宽之间的差异。

Since online gaming requires a lot of quick back and forth, but not necessarily a lot of data, it’s best to have low-latency connections in order to keep the responses between the game server and your computer snappy.

由于在线游戏需要大量的来回快速移动，但不一定需要大量数据，因此最好具有低延迟连接，以保持游戏服务器与计算机之间的响应灵敏。

将笔记本电脑的屏幕用作第二台显示器 (Using Your Laptop Screen as a Second Monitor)

Dear HowToGeek,

亲爱的HowToGeek，

I have heard that you can use a laptop as a second monitor for your desktop. Do you need another graphics card in the desktop or a special cord?

我听说您可以将笔记本电脑用作台式机的第二台显示器。 您是否需要台式机中的其他图形卡或专用线？

Sincerely,

真诚的

Duel Screen

决斗屏幕

Dear Dual Screen,

亲爱的双萤幕：

You don’t need another graphics card or special cable—nor would you likely be able to find a cable as very few laptops have any sort of video-in capability—your best bet is to turn to a software solution. MaxiVista is a popular, but unfortunately not free, solution for Windows. It will set you back $40 but does come with a trial period. The application extends your desktop, over your network, to the screen of another computer (laptop or desktop). A less popular, but free, Windows solution is ZoneScreen. ScreenRecycle ($30) is an option for Mac and Windows users. To extend screens between Macs and between Mac and iOS devices such as the iPhone and iPad, check out Air Display ($20 and $10, respectively).

您不需要另外的图形卡或专用电缆，也几乎不可能找到电缆，因为极少数的笔记本电脑具有任何类型的视频输入功能，您最好的选择是寻求软件解决方案。 MaxiVista是一种流行的Windows解决方案，但不幸的是它不是免费的。 它将花费您40美元，但确实有试用期。 该应用程序通过网络将您的桌面扩展到另一台计算机(笔记本电脑或台式机)的屏幕。 较不流行但免费的Windows解决方案是ZoneScreen 。 Mac和Windows用户可以选择ScreenRecycle (30美元)。 要在Mac之间以及Mac和iOS设备(例如iPhone和iPad)之间扩展屏幕，请查看Air Display (分别为20美元和10美元)。

识别Windows硬件组件 (Identifying Windows Hardware Components)

Dear How-To Geek,

亲爱的How-To Geek，

Is there an easy way to see all the hardware components in my Windows desktop computer?

有没有简单的方法可以查看Windows台式计算机中的所有硬件组件？

Sincerely,

真诚的

Curiosity Killed the Cat

好奇心杀死了猫

Dear Curiosity,

亲爱的好奇心，

There are two simple ways you can check out the hardware in your machine without having to crack open the case. If you’re running Windows Vista or Windows 7 you can open the start menu and type “System Information” in the run box. If you want a more detailed view you can also download the freeware version of System Information for Windows (SIW)—scroll down to the bottom of the page to get to the free version. SIW will give you as intimate picture of your computer as you can get without pulling it apart and checking every serial number of every component.

您可以通过两种简单的方法来检查机器中的硬件，而不必打开外壳。 如果您运行的是Windows Vista或Windows 7，则可以打开开始菜单，然后在运行框中键入“系统信息”。 如果需要更详细的视图，还可以下载Windows系统信息 (SIW)的免费版本-向下滚动至页面底部以获取免费版本。 SIW将为您提供计算机的逼真图像，而无需拆开它并检查每个组件的每个序列号。
