How Are 2.4Ghz And 5Ghz Different?

Gigahertz or Ghz is a frequency uint to measure alternating current and electromagnetic wave frequencies. 1 Mhz is equaled to 1,000,000 Hz, and 1 Ghz is equals to 1000 Mhz. This was a little bit of physics. Now let’s understand these bands in simple words. 

You might be wondering what is Ghz in a laptop. The clock speed in Ghz measures how quickly the CPU can retrieve and interpret instructions. This way, your computer knows to complete different tasks faster. At times, you can benefit from a CPU benchmark to assess how poorly or how well your PC is performing.

Coming to the two bands, 2.4Ghz and 5Ghz. Now we know about Ghz, we can easily figure out these two bands. As the number suggests, 2.4Ghz will provide you with a slow speed, and 5Ghz will give you a faster speed. However, it doesn’t only depend on speed but also the range it comes with.

The range tells you how much area it can cover for you to use the WiFi. So to clear out things, 2.4Ghz comes with a wider range, but data transmission would be slow. And 5Ghz comes with a narrow range, but data transmission would be fast.
