To increase the clock speed of your CPU, you need to either look into overclocking (which is dangerous) or buying a new processor (which will cost anywhere from $40 to over $1000).
That is completely dependant on which games you wish to play. Chances are you will need a faster processor to be able to play games such as Gears of war 2 which requires a minimum of 2.4 Ghz. Unreal tournament 3 - 2.8 Ghz, Bioshock - 2.4, C&C3 - 2.4. You can play Portal though: It only has 1.7 Ghz minimum requirement. basically your not going to be able to play much with a 1.8 Ghz processor and even if you do, the games you play will probably have to be set to the lowest graphics settings and will still lag like crazy.
Yes.
Maybe, it depends on the type of processor, other hardware and software.

Yes it can. I've done it plenty of times (my computer uses a 1.8GHz dual-core). I've played UT2004 and Need for Speed Most Wanted fine on it. Mind you, if your computer has a 1.6GHz processor, increase the RAM to the maximum supported, it really helps.
what is the difference between celeron and ghz speed
The clock speed at which the CPU can run at, the higher the Ghz the faster it runs, but that means it would need to be cooled down much faster than its current fan speed setting. To increase the Ghz in a computer, this would be referred to as Overclocking.
It is closer to 2 GHz.
CPU speeds range from around 1.6 Ghz to around 3.6 Ghz it shows how many times the processor operates in a second.. Ghz - Gigahertz you can increase you computer speed if you want to .. it's called overclocking.. I can't go into the details here. but overclocking will void your warranty.

You should look up "overclocking". Its a pretty popular thing to do at the moment.
The real question is whether the effort and expense are really worth the 6% increase in speed.
It isn't a GHz yet... you need 1024 MHz to make 1 Ghz
The wavelength for 1 GHz is longer than the wavelength for 100 GHz. Wavelength is inversely proportional to frequency, so higher frequencies have shorter wavelengths.
