Difference between I/O BOUNDS JOB and CPU BOUNDS JOB

Ok now the answer of your question is that The jobs or processes which requires more I/O operations like typing on text editors are called as I/O bound processes while the processes in which intense calculations are involved and CPU has to give maximum time to perform those calculations are called CPU bound jobs/ processes.

 The second part is that A thread is created by a process. Existence of a thread is dependent on the existence of a process. It is sometimes called as Light weight process. But threads execute within the address space of the process. A thread has a thread id, program counter, register set. A thread can also communicate with other threads of the same process whereas a process can exist independently.

Difference between I/O BOUNDS JOB and CPU BOUNDS JOB

When you have a job and spend a lot of time using a cpu it is called cpu-bound job. Cpu-bound process has a limited cpu cycle. And when you are performing a cpu-bound job it is more faster when the cpu you were using is fast also. It also performs small set of calculation such as multiplying small matrices.  When you got a job spending a lot of time in i/o it is called i/o bounds job. It has a limited disk for i/o. It is a condition that take time to complete a computation. You have to spent a lot of time to input/output operation to complete. It process a task form a data. Thread tells the computer what to do in an ordered sequence of instruction. And process is the one that runs the computer. It was also mean that performing a series of operation in a set of data.
