What Is Operating System And Its Function – The primary responsibility of an operating system is to distribute resources and services, including memory, hardware, processors, and data. The operating system also has tools to manage these resources, including a file system, traffic controller, scheduler, memory management module, and I/O programs. Software called the operating system controls how computer hardware is allocated. To ensure the proper functioning of the computer system and to prevent user programs from interfering with the proper functioning of the system, the hardware must be coordinated appropriately.

Example: We request or transmit our commands to the operating system in the same way that a boss gives instructions to his employees. The primary objective of the operating system is to improve user comfort and the secondary objective is to use resources as efficiently as possible.

What Is Operating System And Its Function

An operating system is software on which application programs run and acts as a communication bridge (interface) between the user and the computer hardware.

Types Of Operating System

An operating system is system software that serves as a gateway between the user and the hardware that powers a device. The gadget can be a phone, computer or any other instrument. In addition to serving as a link between you and the computer, it assists you with various tasks such as computing, translation, etc. This is comparable to how your doctor acted as a mediator between you and your illness, helping you heal faster. An operating system is created to be able to control all the processes and hardware resources of a computer. Windows and Linux are two examples of popular operating systems.

For a computer to function properly and support applications like Word, Excel, and even the web, an operating system is essential. Your line of communication with the computer is the operating system. It allows you to communicate with him and receive the desired answers in return. The operating system produces all the calculations.

The main task performed by the operating system is the allocation of resources and services, including the allocation of the following:-

The operating system comes with programs that can be used to manage these resources, including a traffic controller, a scheduler, a memory management module, I/O programs, and a file system.

Functions Of Operating System

Primary memory or main memory is controlled by the operating system. Each byte or word in main memory has an address and the array of bytes or words is quite large. The processor can immediately access main memory, which is a form of fast storage. A program must first be loaded into main memory before it can be executed. The following tasks are performed by an operating system to manage memory: It keeps track of main memory or the number of bytes of memory used by each user program. the addresses of the memory already allocated and the addresses of the memory still available. In multiprogramming, the operating system determines the order and duration of memory access for each process. When a process requests memory, it allocates that memory to that process, and when that process has finished or is engaged in I/O activity, it releases that memory.

An operating system helps you achieve your goal of securing your data in today’s society. The capacity of an operating system increases its stability. An operating system uses firewalls to protect against and stop external attacks. The system may only be used by persons authorized to do so.

The operating system keeps track of the time and resources used by each task and user; this data can be used to monitor the amount of each resource used by a specific user or group of users.

The operating system controls the order in which processes access the processor and the processing time each process receives in a multi-programming environment. Process scheduling is the name of this operating system feature. The following tasks are handled by an operating system in terms of processor management.

Function Of Operating Systems

Device communication is controlled by an operating system using the appropriate drivers. The operating system handles the following tasks for device management.

🚀 The input/output controller is software designated by the operating system as being in charge of each device.

Files are where data is saved. We can create, edit, update and delete files using an operating system. Additionally, it facilitates file transfers between devices. Physical entities stored on hardware are considered files.

Directories are used to structure a file system and make it easier to navigate and use. These directories may include additional directories and files. The following file management tasks are performed by an operating system. It tracks information storage locations, user access preferences, file status, and more. The file system refers to these resources in general.

What Is The Function Of The Kernel Of An Operating System?

Depending on the user’s needs, it organizes and assigns tasks to different components of the software, such as interpreters, compilers, etc.

The operating system must monitor the many simultaneous activities, faults committed and interruptions, if any. It can decide to stop the programs in question or to immediately inform users of the defects. By identifying applications or processes that impact and reduce CPU and memory consumption, system monitoring helps us understand the health of the system.

Monitors the status of the entire system to improve performance. For a complete picture of system status, records the time between service requests and system responses.

Additionally, it provides us with the data we need to diagnose system issues. The following Task Manager screenshot provides information about the CPU and memory usage of several Windows operating system activities.

Functions Of Operating Systems: Fully Explained

Networking is highly dependent on operating systems. Distributed systems are a typical example where a server operating system can guarantee consistency between distributed PCs.

The operating system of such a system allows the connection of several independent and geographically dispersed computers via a single communication channel.

As a user, you enter commands in a language you understand. Since the computer primarily understands 0s and 1s (binary language), the operating system handles the interpretation of the commands and then directs resources to process them.

The operating system is responsible for running all programs, whether they are user programs or system programs. The operating system uses various available resources for the efficient execution of all types of functionality.

The operating system is responsible for making decisions regarding the storage of all forms of data or files i.e. floppy disk/hard disk/USB drive etc. The operating system determines how data is manipulated and stored.

The operating system is responsible for detecting any form of error or bug that may occur during any task. A well-secured operating system can also work as a countermeasure to avoid any kind of computer system breaches from any external source and possibly handle them.

The operating system is responsible for handling different types of inputs, such as those from the keyboard, mouse, and desktop. The operating system manages all interfaces for all types of inputs and outputs in the most appropriate way.

For example, the nature of all types of devices, such as mice or keyboards, differs and the operating system is responsible for processing data between them.

Kernel (operating System)

By determining which resource will be used by whom for how long, the operating system ensures the proper use of all accessible resources. The operating system makes every decision.

The operating system keeps track of all operations occurring simultaneously in the computer system. The operating system keeps track of every detail, including the types of failures committed.

The operating system is responsible for making the most secure use of all data and resources on the machine. Any attempt by an external resource to obstruct any type of data or information must be rejected by the operating system.

The operating system ensures that all these services are provided for the convenience of users to simplify programming tasks. The services offered by all the different operating systems are essentially the same.

Kernel In Operating System

• It is a crucial component of any computer equipment, including smartphones, laptops, cameras and other gadgets. Some refrigerators and washing machines are also equipped with them.

• The operating system controls files, processes, storage, external devices and also monitors device related issues.

• Additionally, it ensures that various tasks and processes receive the resources they need for a defined period of time based on their respective priorities.
