Basically an operating system is the single most important program built to run on computer throughout its life, while all other programs may be called apps. In other words, the operating system acts as an interface that bridges the user with that of hardware of the computer. It is this system that controls and guides the application programs on your computer. An operating system or OS in short is notable in its functions like memory storage, information and processors and compatibility to devices. For the users this means great convenience, high efficiency and constantly evolving service.

You will find that no devices can be operational or functional without the operating system. It has two very important purposes and these are it allocates and controls the uses of resources within the computer system for various kinds of tasks and also among different types of users. The other task it performs is that it provides the bridge between the user and the computer with a dedicated interface so as to make it easy for coding, debugging of apps and creating new programs.

Details of Operating System

All computers must be able to manage the memory within their systems, traffic controlling, a scheduler, file system and I/O programs through their own basic level programming that is in-built into the system. In order to make all this possible the in-built system within a computer must have an Interface that allows users, system and application programs and hardware to act in synchrony to achieve the net user’s experience in it totality.

In short, the operating system must have these features so as to give the high-end experience. These may be well protected and supervisory mode and easily allows for disk access and the networking security for the file system. The users may need to execute each program with ease and enable virtual memory management and multitasking. The OS program should be capable of managing I/O operations and also be able to manipulate the files. This would mean that the system instantly recognizes an error and automatically manages it. It again would be able to protect all information and resources as well as ably managing allocation of resources.

You may now get the gist of the whole thing that an OS is set of specialized programs that is always in running mode whenever the system is plugged on. It is therefore quick to note the inputs from keyboard and keep track of files and directories and then send forth output gathered from the same on the display screen including other attached devices.

Operating System Acts as the Manager

The first and foremost part played by a manager in any organization is that he or she gives guidance and goals to rest of the staff. In a computer system the operating system firstly boots the computer so that the rest of the interconnected functions are ready to receive further orders. In fact all the peripheral devices like the mouse, keyboard and CPU are managed by it. Then by giving command guidelines and graphical user interface it gives the users their own unique personal experience.

Then along with the above it shares the CPU time with the help of various application and devices. It then provides help through file management so that you are able to file, save, retrieve and manipulate data. Again, in order to avoid errors it takes measures automatically to prevent it from occurring.

Through processor management it puts the tasks into correct order and makes them manageable before it passes onto the CPU. Through memory management it coordinates data to and from RAM or Random Access Memory. It then also determines the need for virtual memory.

The device management ensures that it provides the interface the moment the computer is connected. There is also a standard communication among the tasks performed that is between the computer and the software. It never allows one task to superimpose on another task and guides the whole system to function in synchrony.

You may choose any one of the top operating system as basically they offer the same standard function although this may again vary from individual to individual and the types of tasks to be performed. …
