Complete Guidance of Operating System

Introduction of Operating System

An Operating system forms the core of any computer device. The function and process of a computer system can come to hold without an operating system.

This article will discuss the Operating System and its various types and functions. The different features and history of OS development have also been discussed.

Define Network Operating System

An operating system is a program that controls the execution of an application program and acts as an interface between a computer user and its hardware.

Functions of Operating System

Process management operating system

operating system in Memory management

File management operating system

Device management

operating system in Security management

Data management

User interface operating system

Error detection and handling

Job scheduling operating system

Controlling resources

Process Management

This system assigns processes to the different tasks that the computer must perform. This processing system has to perform responsibilities like tracking methods in progress. This duty is skilled by the traffic manager and assigns a processor like CPU to process.

Memory Management

It performs the task of allocating and de-allocating memory space to programs needing these resources. There fore ,this program must also be loaded into the main memory before execution.

 Management of Device

This system guides them to navigate and use more efficient files. It makes use of a variety of resources to run all functions smoothly,

Security management

To safeguard the user’s data, it generates a password and takes safety measures to protect the user’s data from fraud.

File Management

This system stores the files on floppy disk, hard- disk, or pen drive and controls how to store and handle them.

Error Deducting and Handling

It controls deducting the errors that may occur during the task and also operates the measures in preventing and handling any interruption in the computer.

Controlling Resources

It guarantees the available resources are appropriately utilized and used by whom and for how long.


Error detection and handling

Handling I/O operations

Virtual Memory Multitasking

Program Execution

Allows disk access and file systems

Memory management

Protected and supervisor mode


Resource allocation

Easy to run

Information and Resource Protection

Manipulation of the file system

Benefits of Operating System

Source of computing

Under this system, a software program connects the user to the hardware, allowing them to enter data, process, and view the results. Users can also interact with computers to perform various operations, such as arithmetic calculations and also with other critical tasks.

Sharing Resources

This system shares essential information and data by Printers, modems, players, and fax machines. We can also send e-mails to several users, printers, modems, players, and fax machines.

Data Protection

On the computer, a lot of user data is edited with the help of an operating system. Apart from storing and accessing data, an OS’s other crucial role is to handle data safely and securely. Windows Protector finds and rejects dangerous and harmful files in Microsoft Windows and also protects your information by coding it bit by bit.

involvement of Coding Lines

Thanks to the GUI, operating systems allow users to access hardware without writing programs. Users do not need to write lines of code to access the hardware capability of a computer system as they did previously.


How ever it can manage multiple tasks at once but, also enables the users to complete various things at the same time.

Updated software

This is a part of software that needs to be updated regularly to keep up with the fast-changing features. OS must increase benchmarks and handle all aspects of computer operation as other programs and software receive upgrades to improve their usefulness and update easily.

System Error

If this gets fails, the machine will stop working, and the computer  cannot work without an operating system. If the central system fails, all statements will get disturb, and no further data processing will be possible.


Some of these systems are more expensive than open-source stages, like Linux. While free operating systems are available, they are frequently more exciting than others. Therefore, operating systems with GUI functionality and built-in features like Microsoft Windows are expensive.

Complex Structure

These systems are enormously complicated, and the language used to create them is poorly transparent. If there is an issue with the OS that users do not understand, it cannot be static quickly.

Threats from Viruses

There fore, threats are inferior since they are also more exposed to viral attacks. Many users install hateful software letters on their computers, which may cause them to stop working and slow down.

Fragmentation in operating system

When the data is store, in a computer’s memory separates, also known as destruction’s. This Internal destruction develops when the processing technique is larger than the memory size. When a method or process is removed, exterior destruction happens.

In this article, we came across so


me meaningful information about the Operating system, which is helpful to you where we have discussed its meaning, functions, drawbacks, and more. To know more details, visit our website, Quora blog.
