Introduction of Operating System Essay
Operating System Essay -We are living in an Era of machines and gadgets. Daily use handheld devices, like mobiles and computers, rely on an Operating System to give them the most preliminary instructions. Your computer, however good it may be, is of no use without an Operating System. After all, it is a machine. A machine always needs instructions to work without which they are just dummies.
The same goes for a computer or a handheld device. It is even required to start and shut down the computer. All computers handheld computers, desktop computers, supercomputers, and even modern video game consoles, use an Operating system of some type. Even a task, as simple as printing a document, needs instruction to be passed to the printer for it to operate.
An operating system is system software that controls the internal activities of a computer system and its hardware. It also provides a user interface.
- Application programs also interact with the operating system.
- The operating system is the first program that is loaded into the computer’s main memory.
- An operating system is also concerned with allocating and deallocating computer resources.
Types of operating system
- Single user operating system:- A single-user operating system allow only one user to work on the computer at a time. Examples are Dos, window 7, 8,10,2000, and XP, 98,95.
- Multi-user operating system:- A multiuser operating system allows multiple users to work together on a computer at the same time. In this type of operating system, a terminal is provided to each user. Examples are UNIX, LINUX, etc.
- Multitasking operating system:- Those operating system can perform multitasking at the same time is called a multitasking operating system. Ex:- windows X
- Real-Time operating system:- the operating systems of these types can control time involvement such as rocket control space vehicle and chemical reactions control these have highly quick responses. Ex:- VT – Work, HP – RT.
- Networking operating system:- Operating systems of this type are ideal for networking involvement and the ability to control clients. Ex:- windows server – 2007,2010,UNIX, LINUX.
- Distributed operating system:- the operating system of this type provides virtual unique processing involvement for computing in these operating systems or resources become a single unit for solving problems and get a single processing involvement. Ex:- UNIX, LINUX
- Mobile operating system:- Which operating system is used to control mobile phones is called a mobile operating system. Ex:- Android, Blackberry
Parts of the operating system
Generally, all operating systems consist of two major parts – Kernel and Shell.
- The kernel: The kernel is the hub of the operating system. The main function of the Kernel is to interact with the hardware. It allocates time and memory to program and handles the file store and communications in response to system calls.
- The Shell: The Shell is responsible for interacting with the user. The Shell acts as an interface between the user and the kernel. The Shell is a command-line interpreter (CLI). It accepts the commands from the user interprets the commands and takes appropriate action. The commands are themselves programs: when they terminate, the shell gives the user another prompt.
Functions of operating system
- Process Management:- The operating system assigned the processor to the different tasks that must be performed by a computer system.
(a) creating and removing process.
(b) controlling the progress of the process.
(c) Provide a means of communication among processes through messaging.
- Memory management:- memory management if alerts the main memory and secondary memory to the system program, user program, and data program by memory swiping techniques. In which a bigger program is first broken into small parts and loses into main memory from the secondary storage device. It is also responsible for creating virtual memory.
- Input /Output Management:- This a is a program that helps input and output devices by creating a system many inputs or output devices are controlled by its device drivers.
- File Management:- In manages file on various storages devices and then transfer these files from one storage device to another.
