Advantages and Disadvantages of Operating System

An operating system is the heart of any computer without which it cannot withstand. It provides all the resources to software, manages the hardware, and implements all standard services for computer programs. In this article, we are going to discuss the advantages and disadvantages of an operating system. So let’s get started with the basics.

Operating System Definition

An operating system is a software that controls all the working of computer architecture, including hardware, peripheral devices, and all other components. It takes input from the user, processes the data, and generates output for the same. Besides, it also acts as an interface between the hardware of the system and the user. Moreover, an operating system is designed to perform various tasks such as processing information, arithmetic calculations, task scheduling, memory allocation, and deallocation, etc.

Types of Operating Systems

  • Batch Operating System
  • Time-Sharing Operating System
  • Distributed Operating System
  • Network Operating System
  • Real-Time Operating System

Advantages and Disadvantages of Operating System

Advantages and Disadvantages of Operating System

There are different types of operating systems that have been transformed over time. As each operating system has its benefits and downsides, that’s the reason new operating systems have been developing. Now let’s look at the following advantages and disadvantages of an operating system.


Computing Source

An operating system acts as an interface between the user and the hardware. It allows users to input data, process it, and access the output. Besides, through the operating system, users can communicate with computers to perform various functions such as arithmetic calculations and other significant tasks.

User-Friendly Interface

Windows operating system, when it came into existence, also introduces Graphical User Interface (GUI), which made using computers much more natural than earlier Command Line Interface. Moreover, users can quickly understand, interacts, and communicate with computer machines.

Resource Sharing

Operating systems allow the sharing of data and useful information with other users via Printers, Modems, Players, and Fax Machines. Besides, a single user can share the same data with multiple users at the corresponding time via mails. Also, various apps, images, and media files can be transferred from PC to other devices with the help of an operating system.

No Coding Lines

With the invention of GUI, operating systems allow accessing hardware without writing programs. Unlike, earlier users don’t have to write code of lines to access the hardware functionality of a computer system.

Safeguard of Data

There’s a lot of user data stored on the computer, and that can only be accessed with the help of an OS. Besides, storing and accessing the data, another important task of an OS is to safely and securely manage the data. For example, Windows Defender in Microsoft Windows detects malicious and harmful files and removes them. Also, it secures your data by storing them with a bit to bit encryption.

Software Update

An operating system is a software which needs to update regularly to control high fleeting features that are continually increasing. With other apps and software hitting updates to improve their functionality, OS must improve their benchmarks and handle all the working of a computer. An OS can easily be updated without any complexity.


An operating system can handle several tasks simultaneously. It allows users to carry out different tasks at the same point in time.

Other Advantages

  • An OS allows installing of different types of apps and run them
  • OS improves work efficiency and saves time by reducing the complexity
  • Also, it helps in reducing the efforts need to access various data
  • Data can be copied, deleted, moved, and restored from the computer system
  • Every system component is independent of each other, so the failure of one system will not affect others



When compared to the open-source platforms like Linux, some operating systems are costly. While users can use a free OS but generally they are a bit difficult to run than others. Moreover, operating systems such as Microsoft Windows with GUI functionality and other in-built features carry a costly price tag.

System Failure

If the central operating system fails, it will affect the whole system, and the computer will not work. Moreover, an OS is the heart of a computer system without which it cannot function. If the central system crashes, the whole communication will be halted, and there will be no further processing of data.

Highly Complex

Operating systems are highly complex, and the language which used to establish these OS are not clear and well defined. Besides, if there’s an issue with OS users cannot directly understand, and it cannot be resolved quickly.

Virus Threats

Threats to the operating systems are higher as they are open to such virus attacks. Many users download malicious software packages on their system which halts the functioning of OS and slow it down.


Fragmentation in the computer is a state when storage memory breaks into pieces. Internal fragmentation occurs when the method of process is larger than the memory size. External fragmentation occurs when the method or process eliminates.

So, these are the following advantages and disadvantages of the operating system. If you have any other queries or related doubt, then please let us know in the comment box below.

  1. Well, I came here to see the Disadvantages, as OSes are designed to make lives easier, how there can be DIsadvantages :), and every Disadvantage you have listed has an Answer;

    Expensive: Linux is free, and You may also have the Licensed version of Windows, and we all know
    System Failure: Do you really want the OS to let people do anything, even if they are trying to damage their own hardware, and not crash the system when any critical situation is just gonna happen?
    Highly Complex: Man… :), Okay, if we really talk about Complexity, the Linux Kernal is only of 32MBs in Size in its Minimalistic state (used in Embedded systems). I have a lot to say here, but it’ll waste the time
    Threat Protection: Well, honestly speaking, don’t you think if you don’t have an OS, and I share an Assembly File, which will directly Communicate with your CPU and destroy your RAM, SSD, and GPU as per my instructions? But, what if you have an OS?
    Fragmentation: Well… I’m tired to say, but do you really think people won’t Bloat their resources with Unnecessary Copies of the Same stuff, or have trouble finding them. And if you really say, “OS CAUSES FRAGMENTATION” there is only a 5% chance of Fragmentation, and now SSDs have no risk of Fragmentation at all
