To have a full grip on your device, it is important to have a reliable operating system.  Managing memory, storage or CPU is a task that a good quality OS will execute easily. When choosing the operating system that meets your needs, you must look at the characteristics and commands that are important to your type of work. Take a look at the following characteristics and decide if Linux is the OS for you.

What is Linux and Why you Should Use It?

According to Milos, an avid user of Linux and webmaster of RealSpyApps, Linux is software with an array of tools and functions, based on the Linux kernel. What makes Linux the ideal software for many is the fact that it’s open-source software. It will let you choose and set up preferable components, for example, if you are looking for graphics, you can make it the core component. 


Since the software is open-sourced, it will guarantee you more security. Not only that, but each Linux user must have an ID and a password, making it harder for malware to go through. These specifics make Linux much more secure than other software.
