I have 1 CPU,
it runs 5 threads,
each thread can run several instructions.
for each thread, it runs its instructions one by one,
you can only run instr2 after instr1 finishes.
but from CPU's point of view,
it can run only 1 instruction at a time.
each instruction can take 1, 2, 3, ... or 24 ticks to finish,
dont't worry about the number here,
basically the instructions take different time to complete.
