Understanding Context Switching in Linux - Network Nuts

We will learn how a CPU manages multiple processes. What is a time slice? Different types of context switching. Voluntary and In-voluntary context switching. Understanding about context switching helps us understand Linux operating system in a better way. Context switching is a kernel routine where kernel tells a CPU to work in a different context.

Good one sir..

Isn't involuntary context switching happening with 'dd' since it is constantly having to wait for I/O syscalls to finish? While it is waiting, it is not leaving the CPU until the CPU time slice is up. Thus, it sends data through a syscall, waits for the time slice to finish and only returns to the context switching queue when an I/O IRQ occurs.
