i know os schedules thread , cpu executes , there direct relationship between no of threads , no of cores.is mean single processor multiple cores (say n) same of n single core processors, mean in both of these cases processing ability same or there difference?
yes, there difference, normal programming decisions difference insignificant , low-level.
