When buying a laptop what does GHZ mean?
Laptop or desktop, GHz means the same thing. First off, Hertz (Hz) means “cycles per second” and is a common way of talking about waveforms in physics and electronics. The “G” in front means “giga” and that prefix stands for a billion. The microprocessors in computers are commonly rated by something called their “clock speed,” and that is rated in GHz (giga Hertz), and the rating indicates how many instructions per second the chip can manage. In general, more GHz is better, so you’d want to pick a 2.4 over a 1.8. But whether or not you’ll even notice the difference depends on what you’re doing with the computer. If you’re just doing word processing and simple Internet surfing, you’ll never be able to tell the difference. However, other applications require faster processors. For example, if you do any kind of music recording, a fast processor is essential. By “music recording,” I’m not talking about changing your CDs to MP3 files to listen to on your portable device, but rather actuall
