A cordless phone is 5.8 gigahertz. This is wi-fi.

无线电话是5.8千兆赫 这个是无线网络。

6 gigahertz standard, and there's an option to go to 1.8 gigahertz if you want.

标准版是1.6千兆赫兹，如果你需要的话，也可以选择1.8千兆赫兹。

Bluetooth uses the 2.4 gigahertz frequency to communicate with other devices.

蓝牙通过使用 2.4 千兆赫的频率信号来与其他设备通讯。

Wi-Fi is all about transmitting and receiving data in the gigahertz (GHz) range.

WiFi 被用来传送和接收数据，频率高达千赫兹。

Thats over ten million cores in total...and each one of those cores runs at 1.45 gigahertz.

总共有超过 1000 万个内核… … 而且每个内核都以 1.45 GHz 的频率运行。

Most Wi-Fi networks use the 2.4 gigahertz frequency, which only has a certain number of channels, or subdivided frequency ranges, to broadcast on.

大多数 Wi-Fi 网络使用 2.4 GHz 频率，只有一定数量的频道或细分的频率范围可以广播。

Newer 5 gigahertz networks have more channels available, which makes this less of a problem, but not all routers and devices can use them.

较新的 5 GHz 网络有更多可用信道，这使得这个问题不那么严重， 但并非所有路由器和设备都可以使用它们。

Sales Clerk: Well, this desktop over here is our latest model. It has a four gigahertz processor with sixteen gigabytes in RAM and a hard disk with one terabyte.

嗯，这边这台台式机是最新款。它有四个千兆赫处理器，16G的内存，以及一个1TB的硬盘。

And a modern CPU, for example, why does it run at four gigahertz and not 40 gigahertz? I mean, we can create clocks that are, I don't know, 40 gigahertz.

以现代 CPU 为例，为什么它的运行频率为 4 GHz 而不是 40 GHz？我的意思是，我们可以制造频率为 40 GHz 的时钟。

Instead, 12 teams around the world will set up radio telescopes calibrated to the same frequency -- 230 gigahertz -- all pointed at our supermassive black hole neighbor, Sagittarius A.

相反，世界各地的 12 个团队将架设校准到相同频率（230 千兆赫）的射电望远镜，全部瞄准我们的超大质量黑洞邻居人马座 A。

The chip, designed to power person computers, has a speed of 1.5 gigahertz, making it almost twice as fast as Intel's popular Pentium 3 chip which runs at 800 megahertz.

该芯片旨在为个人计算机提供动力，速度为 1.5 GHz，几乎是运行速度为 800 兆赫的英特尔流行奔腾 3 芯片的两倍。

It's got a 3.2 gigahertz, 16-core Intel Xeon W processor, two Radeon Pro VEGA II graphic cards, 96 gigabytes of RAM and one terabyte SSD. And on paper, it is a total beast.

它有一个 3. 2 GHz、 16 核 Intel Xeon W 处理器、两个 Radeon Pro VEGA II 显卡、 96 GB RAM 和 1 TB SSD。 在纸面上， 它完全是一头野兽。

One megahertz is one million clock cycles per second, and the computer or even phone that you are watching this video on right now is no doubt a few gigahertz -- that's BILLIONs of CPU cycles every… single... second.

1 兆赫兹是每秒一百万个时钟周期，而您现在正在观看此视频的计算机甚至手机无疑是几千兆赫兹——即每… 每秒数十亿个 CPU 周期。
