Most of us use computers, and if you use one, you have probably come across the term OS or operating system. The OS is a vital component of a computer. This is because a computer cannot function without one.
So, what is an OS? OS or operating system refers to the software that allows your computer’s hardware components to perform basic tasks. The OS forms the connection between the user and the computer’s hardware.
Functions of an OS
An OS can be complex, expensive to purchase, and vulnerable to attacks. These tips from Tony Monzone will help you understand what your OS does and will help you know what you need to get. An OS is mainly used for:
- Memory management. One of the major works of an OS is to manage the allocation and deallocation of memory among different processes. This helps to ensure no process uses memory allocated to another.
- Process management. A program cannot work without receiving instructions from the CPU, and it is the work of the OS to assign different jobs to the CPU.
- The OS has various systems put in place to ensure that user data is protected by adding a firewall that can prevent unauthorized logins and malicious attacks and informing the system of any vulnerabilities.
- File management. The OS manages the creation, deletion, distribution, and storage of files in the system.
Types of operating systems
Both the hardware and software applications cannot work without an OS. Most computers nowadays come with pre-installed OS software. Though there are different types of OS, most people only know of Windows and macOS.
- Microsoft Windows. Windows is the go-to OS for most people because it is user-friendly and has built-in security systems. The user interface allows anyone, regardless of their age and the PC they have to maneuver around.
- macOS is an exclusively Apple OS and comes with Apple devices. It looks amazing and offers free upgrades. macOS is the most popular OS among video editors and graphic designers and offers the best security. It has certain similarities to the Linux OS, and you can install it on other devices.
- Though Linux OS is not as common as Windows or macOS, many corporates and academic institutions use Enterprise Linux. However, this OS is more complicated and can take time to learn.
- Chrome OS. This OS works best with Chromebooks and is slowly becoming a contender in this space due to its simplicity. Unfortunately, you can only access the Chrome web browser and apps.
- Free BSD. Berkeley Software Distribution is an OS similar to Linux. It is an open-source OS that was mainly developed for researchers. It is favored by advanced users working with network security. However, it does not have a lot of support.
- Apple devices can only use apple software, while you can use other software on a Windows PC.
Factors to consider
Security
What are your security needs? If you work with highly sensitive information you are better off with macOS and Linux rather than Windows. Though Windows has built-in security measures, its popularity is favored by cybercriminals making it vulnerable to attacks. You will probably need to add third-party anti-malware software.
Updates
In your search for the right OS, you need to get one that keeps up with the ever-evolving technology. Updates are also useful as they keep your PC safe from any vulnerabilities.
Stability
A stable OS is important in ensuring your computer does not keep shutting down. An unstable laptop can be frustrating for everyone, especially for those who need to keep their machines on for long periods. Both Windows and macOS offer excellent stability.
Programs That Will Run
What programs will you be using on your laptop? Answering this question will help you know what OS you should use. For simple functions, Windows is the OS of choice for many. For programs that require heavy use, like media production and design, a macOS will be able to handle the work.
Memory Management
When choosing an OS, you need to find one that can handle processes well and equally distributes the functions. If you are using an old computer, Linux OS is the best option because both Windows and macOS are very resource intensive.
Budget
How much are you willing to spend? Your budget ultimately determines the PC model you choose. Since most low-end PCs come with Windows installed, it automatically becomes the OS of choice. Linux is free and can be installed on any machine. Apple computers generally cost more.
Support
It is important to look for an OS that has external support. Sometimes things don’t run as expected and you will need help to figure it out. Both Windows and macOS offer great support not only from the manufacturers but also from the various experts online.
In summary
If you want, you can use two different OS according to your needs. You do not need to deeply understand an OS to know how it works, and I hope this article has been useful in guiding you toward the right option.
