Obtain the eigen values of the matrix $$$A = \left[ {\matrix{ 1 & 2 & {34} & {49} \cr 0 & 2 & {43} & {94} \cr 0 & 0 & { - 2} & {104} \cr 0 & 0 & 0 & { - 1} \cr } } \right]$$$

The function $$f\left( {x,y} \right) = 2{x^2} + 2xy - {y^3}$$ has

Which of the following scheduling algorithms is non-preemptive?

Draw the process state transition diagram of an $$OS$$ in which
(i) each process is in one of the five states: created, ready, running, blocked (i.e. sleep or wait), or terminated, and
(ii) only non-preemptive scheduling is used by the $$OS.$$ Label the transitions appropriately.
