Distinguish between CPU bounded, I/O bounded processes.

Sure, here is a step-by-step explanation to distinguish between CPU bounded and I/O bounded processes:

1. Definition:

   • CPU Bounded Process: These are processes or tasks that require significant computational processing. The speed of these tasks is limited primarily by the speed of the CPU. Examples of CPU-bound tasks include complex calculations such as mathematical simulations, video encoding, etc.
   • I/O Bounded Process: These are processes or tasks that spend more time doing input/output operations than computation. These tasks are limited by the speed of the I/O subsystem (hard drives, SSDs, network etc.). Examples of I/O-bound tasks include reading or writing files to a disk, downloading or uploading data from the internet, etc.

2. Resource Utilization:

   • CPU Bounded Process: These processes make heavy use of the CPU as they involve a lot of calculations. They keep the CPU busy and utilize the maximum capacity of the CPU.
   • I/O Bounded Process: These processes do not use the CPU resource intensively. Instead, they use I/O devices like hard disk, network, etc. They spend more time waiting for I/O operations to complete.

3. Performance:

   • CPU Bounded Process: The performance of these processes can be improved by increasing the speed of the CPU or by optimizing the algorithm to reduce the number of calculations.
   • I/O Bounded Process: The performance of these processes can be improved by increasing the speed of the I/O subsystem, using faster disks, or optimizing the I/O operations to reduce the amount of data read or written.

4. Scheduling:

   • CPU Bounded Process: These processes are often given higher priority by the CPU scheduler to ensure they complete in a reasonable amount of time.
   • I/O Bounded Process: These processes often have lower priority as they spend most of their time waiting for I/O operations to complete. However, they can be given higher priority if the goal is to improve the responsiveness of the system.

In summary, the main difference between CPU bounded and I/O bounded processes is the resources they primarily use and the way to optimize their performance.
