OS Overview Q & A #4
Question: What inconveniences that a user can face while interacting with a computer system, which is without an operating system?
Answer: Operating system is a required component of the computer system.
Without an operating system computer hardware is only an inactive electronic machine, which is inconvenient to user for execution of programs.
As the computer hardware or machine understands only the machine language. It is difficult to develop each and every program in machine language in order to execute it.
Thus without operating system execution of user program or to solve user problems is extremely difficult.
