All You Need To Know About Operating System
An operating system is a collection of program files and routines which control a computer’s resources as well as it provides access to a computer’s services. It allows a computer’s hardware components such as processors and drives, to communicate with its software components like applications and data instruction sets. It enables the computer hardware to communicate and operate with the computer software. The importance of operating system will make the computer system convenient to use and to utilize computer hardware in an effective manner. The operating system is used on the computer which is mainly to operate and to safeguard the system from the virus. There are many kinds of operating system that are suitable for different versions of the computer system. It performs the basic tasks like receiving input from the keyboard, processing instructions and sending the output to the screen. It is used to run the application programs and utilities so it works as a bridge to perform in the interaction between application programs and hardware of the computer.
Characteristics of operating system
- · It is a collection of programs which is responsible for the execution of other programs
- · It controls all the input and output devices that are connected to the system
- · It will allow running all the application software’s
- · Provides scheduling to the various processes
- · Provides the communication between the user and the system
The CPUs are more responsible for resulting the computer commands and the slowest CPUs can process the data in microseconds. The compiled program or the executable program has to be executed by the CPU to give the users the preferred output. It cannot access directly the secondary storage memory and the program should be brought from the secondary memory to the main memory for execution after implementation. The data or program should reside in main memory when a piece of the program has to be executed by the CPU. A user will be unable to provide a modern computer with the instruction sets or commands without an operating system because it acts as an eco-friendly manner. A user can give virtual, software-based commands through a keyboard, mouse or other input device using an operating system which simplifies the instruction process. An operating system will serve as a process manager of computer and it is responsible for conglomerating, and organizing those resources. The importance of operating system is that other process-managing tasks of an operating system which includes the process of creating and deleting, scheduling processes and synchronizing processes. The interaction with peripherals or secondary, non-essential input or output devices on a computer would be much more complicated without an operating system.
Benefits of operating system
- § Support for modern technology
- § Improved productivity
- § Enhanced security
- § Better manageability
- § Improved stability
- § Lower costs
The importance of operating system has to ensure that the applications are able to run in the amount of memory available and they do not interfere with one another. The data packets traveling to and from the connected computers on the network are handled by the operating system.
