whats the difference between different amout of gigahertz like 1.86 and 2.00?

Answer 1

in relation to radio waves, such as what cordless phones use... . the LOWER the frequency of the wave, the FURTHER the signal will travel if all other variables are equal (same transmitting power etc) the HIGHER the frequency of the wave the SHORTER the distance the signal will travel, as it wil use up all of its energy faster..

900Mhz phones transmit with a much lower TX power then newer phones and therefore even tho it is a lower frequency, it still has poor range...

2.4 Ghz phones have better range then 900 Mhz phones BECAUSE they have a higher TX power. If there is no interfearance from WiFi or other signals then 2.4 Ghz phones SHOULD have better range then 5.8Ghz phones

5.8 Ghz phones came out after 2.4Ghz phones, and as we have always been taught bigger is better, we are lead to assume it transmitts further then 2.4 ghz. this assumption however is WRONG... 5.8 Ghz phones have LESS RANGE then 2.4ghz phones. They were introduced into the market because the popularity of WiFi which operates at the same frequency range as 2.4Ghz phones, and create interfearance.

DECT 6.0 operate at 1.9 Ghz, and therefore provide the furthest range out of all previous cordless phones

Answer 2

140 megahertz but realistically not much. There are numerous factors in determining the speed of the computer. The CPU chip is rated for number of cycles per second it can turn on and off. THe best way to computer similar processers on speed alone is to just take the ratio 1.86/2.00 = 93%. So the 1.86 is 7% slower than the 2Gig. That is a very small difference in speed. For 99% of users you will not be able to tell the difference. On more current computers, you will have multiple cores (CPUs) being used. This allows more data to be processed. So absolute speed isnt always the final factor. You have the speed of the Random access memory, speed of internal communications, speed of hard drive access, video card speed/capabilities software etc etc etc. It is very complicated. If you use your computer for Internet email and some light word processing and viewing most videos you do not need the fastest chip. Your speed of your Internet connection is the most important. If you are a hard core gamer or do heavy video work, speed can make a difference.

Answer 3

The difference is roughly 7%. However, in the land phone section that can also be just a consideration of frequency spectrum. The higher the frequency, the shorter the wave length. The older cordless phones operated in the 46/49 megahertz band. As technoligy has improved we now have phones that operate at frequencies well up in the gigahertz portion of the radio frequency spectrum.

Answer 4

Gigahertz refers to the number of computing operations that the processor can do in one second. So a 1.86 Ghz processor does 1.86 billion operation per second. 2.00 Ghz is 7.5% faster then a 1.86 Ghz one.
