Work Step by Step

As the lengths of the time slices in a multiprogramming system are made shorter and shorter, the problem of increased overhead due to context switching arises. Context switching is the process of saving and restoring the state of a CPU so that it can switch between different processes. When time slices are short, the CPU must perform context switches more frequently, which can lead to inefficiency and reduced overall system performance. On the other hand, as the time slices become longer and longer, the problem of poor responsiveness arises. Longer time slices mean that a process must wait longer before it can regain control of the CPU, which can lead to slower response times for interactive applications and a perception of sluggishness from the user's perspective.
