Which is better mhz or ghz

An LED that blinks at one Hz would blink on and off every second. An LED that blinks at 1 kHz would blink a thousand times a second - so fast that you would even notice that it was blinking.

When building robots, you may be concerned about the speed of the microcontroller's clock ticks, the frequency rate of a PWM signal, or the pitch of a tone being sent to a speaker. Hertz, or Hz, is the term used in wireless communications to refer to the number of cycles per second. This is known as the frequency that also corresponds to the transmission of radio signals in cycles per second. In this current age, all technologies are associated with increasing capacities and speeds in the area of computing and telecommunications.

One GHz equals one billion cycles per second. Thus, GHz is a unit of frequency. GHz is used to refer to radio frequencies, sound frequencies, and computer processors at higher frequencies. In computers, GHz refers to the clock speed of the central processing unit. The faster the CPU clock ticks, the faster will be the data and instruction processing. Computer speeds have moved from 1 GHz in to 4 GHz at the present time.

GHz is also used in radio communications to define the different electromagnetic spectrum bands. Such routers are referred to as dual band and triband routers. For many decades now, WLANs have been using the 2. But over the years, there has been a huge increase in the number of wireless devices in our lives and this has revealed the weaknesses of the 2. They provide a clearer, less noisy signal and can be combines for higher speeds triband routers.

This broadcast channel also does not suffer from overcrowding as they can handle more traffic more efficiently. The following are the perks of this channel over 2. The following table highlights the difference in speed and range for the 2. It is difficult to mention routers processing and network standards without getting into what dual band and triband routers are.

Almost all routers today are either dual band or triband routers. With a dual band, it broadcasts both a 2. When connecting to a dual band router, you find that there are two Wi-Fi networks detected by your devices. Usually, devices connect to the 2. There are two types of dual band routers. Here, the router offers a 2. You need a switch to be able to change the channel of the router. This router also broadcasts the two channels. However, you are able to separate each band so that devices use both of them.

Here, you will find that your devices detect two Wi-Fi networks from one router. A few routers allow you to change the name and password for both bands so that the devices see only one network. Simultaneous dual band routers are slightly more expensive but are worth the extra cost since the benefits outweigh the price. However, this is much more difficult to do on laptops or notebooks than on desktop computers, where you can access and replace components with relative ease.

Depends what you use your computer for. If you are browsing the web and such, I would say any laptop nowadays will be good. If a fast processor is coupled with more RAM, then the machine will work quickly. Modern laptops rarely ever run always at 2. If yours does then expect subpar battery life but very good performance.
