how many tasks a pc can do parallelly.
e.g. a pc has resources like CPU and I/O. likewise
how many things can be done parallelly without using CPU.
and this i mean, not any simulation but actual execution of any task
""without using CPU.""
1. a I/O
2. Network access (???)
3. Screen refresh (???)
I am under impression that apart from CPU there are some dedicated processors which are ment to do certain specific task in a pc, independent of CPU. if this is right how many dedicated processors are there in a pc??
