As above.
Thanks!
Because all the data is there?
the faster U load the OS into memory...the faster the boot-up.
ssd ftw in this instaance
What happens after the OS load into memory?
my memory super slow =.=
After OS has been loaded into memory, all essential programs are now memory-resident and can be accessed really fast. Anything NOT in memory, however, has to be read from the HDD.
Vista and 7 use something called SuperFetch. Basically, your most-used programs are loaded into memory during boot-up as and when you have enough RAM to go around.

I didnt mean it this way.
I wanted to know what happens from the time OS is transferred to memory until the time i see it on screen.

The OS boots from the hard drive. It reads from the HDD, puts it into RAM and uses it from there. Once you see the log-in screen, most services and programs required for boot-up would have been stored in RAM already. So once essential services have been stored in RAM, you would have seen Windows log-in already.

when OS is loaded into memory...they are stored in places known as memory addresses...
The CPU chip will execute instructions from these memory addresses...depending on what the memory address stores...it will display...compute...etc
The faster the CPU chip...the faster the execution...
The more the memory...the more codes are loaded into memory for fast access.
In the computer system the slowest speed device that contain important data for the os to load is the hard drive. that is the bottle neck of all computer system. so if your computer hard drive is faster, the overall performance can be improved.
