# Best Operating Systems - Page 4

  *By [Shalaka Joshi](https://research.g2.com/insights/author/shalaka-joshi)*

   Operating systems (OS) allow users to perform the basic functions of a computer. The [best operating systems](https://learn.g2.com/best-operating-system) oversee all software and peripheral hardware and accesses the central processing unit (CPU) for memory or storage. It also makes it possible for a system to run applications simultaneously.

All PCs, laptops, tablets, smartphones, and servers require an OS. Developers may opt for specific operating systems more conducive to programming and application development. In contrast, the average employee will likely use a proprietary system for more common, everyday usage. The most common operating systems for businesses are Microsoft’s Windows, Apple’s OS X, and Linux distributions, as well as mobile operating systems for smartphones.

To qualify for inclusion in the Operating System category, a product must:

- Manage a device’s software and external hardware
- Allow for simultaneous use of applications
- Connect with the central processing unit for memory and storage allocation

## Buyer Guide

### What You Should Know About Operating Systems 

### What is an operating system?

An operating system, or OS, manages a computer’s hardware and software resources and provides common services for computer programs. The OS controls the computer's resources as the system interface between the hardware components and the user. Every computer system requires one OS to run several software programs. 

Whether it is common tasks like [document creation](https://www.g2.com/categories/document-creation)and [browser software](https://www.g2.com/categories/browser) or highly specialized applications, numerous computer applications rely on operating systems as a foundation for storage and execution. The OS takes care of it, as these applications cannot directly interact with hardware.

The majority of store-bought personal computers come with pre-installed modern operating systems. Mobile devices also have their form of OS (such as Android and iOS). In many cases, a user can install different OS software on top of the embedded systems already present within a computer. 

Some of the main functions of OS platforms include memory management, device management, file management, security, error-detecting aids, and CPU management. OS also manages different device's file structures and regulates user access and control.

### What are the common features of an operating system?

Operating systems offer a range of core features that users find highly beneficial, including:

- **Software updates** : Regular updates ensure the operating system stays current with advancements, improvements, and security patches. These updates, from aesthetic enhancements to critical security fixes, showcase the developers' commitment to continuous support and improvement.
- **Vendor support** : Modern OS offers streamlined vendor support through online communication channels. Users can easily connect with developers to offer feedback, address performance issues, or troubleshoot problems. Built-in support features, tutorials, and help articles provide a seamless support experience.
- **Applications** : Operating systems have proprietary programs, from note-taking and media players to games and calculators. Such applications are often key for users when choosing an operating system, as they enhance the overall functionality and user experience.
- **Permissions** : The permissions feature allows users to manage access to the system and maintain security and privacy on shared devices. It enables users to create multiple accounts on a single computer, delegate access to employees, and control file and program access. 
- **Security** : Operating systems emphasize security as a paramount feature by acting as gatekeepers for files, data, and critical applications. OS platforms have built-in security offerings to identify, block, and combat threats. These security measures, including recovery tools, protect against hacks, viruses, and system failures.

### What are the benefits of an operating system? 

The benefits of using an operating system include:

- **Device control** : The primary role of an operating system is device control. It acts as the intermediary between the hardware and users. It allows the loading and management of applications, enabling users to interact with the device seamlessly.
- **Customizable graphic user interface (GUI)**: A GUI simplifies computer communication, allowing users to manage and execute various tasks efficiently. Operating systems facilitate the process by providing users with a smooth and customizable GUI. 
- **Resource sharing** : OS platforms facilitate the sharing of resources among different devices, including modems, printers, and music players. Users can easily share files via emails or transfer data to other devices, promoting collaboration and connectivity.
- **Non-requirement of coding** : The OS is a user-friendly platform, eliminating the users’ need for coding knowledge to access and utilize computer functionalities. This enhances accessibility for a broader user base.
- [Data security](https://www.g2.com/glossary/data-security-definition): Operating systems are crucial in safeguarding user data. Using bit-to-bit encryption, the OS ensures that sensitive information stored on the computer remains secure and can only be accessed by authorized users.
- **Memory management** : The OS oversees memory allocation and utilization and optimizes RAM and other memory resources. This ensures that applications run efficiently and do not overload the system, improving overall performance.
