Linux Unix Uses & Stats

Desktop Mainframe Computers Mobile Devices Embedded Devices

Pros
Performance:
Linux supports many efficient tools and operates them seamlessly. Because it's architecture is lightweight it runs faster than both Windows 8.1 and 10. 
 
Security:
Because Linux is an open-source software,  anyone can contribute code to help enhance the users’ experience i.e., adding features, fixing bugs, reducing security risks, and more.
 
 
Software Development:
The terminal in Linux is a *wild card*. You can do almost anything with it. This includes software installation, application and server configurations, file system management, and etc.
 
Large-scale:
Open-source projects benefit from having an attentive community. As a result, Linux is more secure than Windows. Instead of installing anti viruses to clean malware, you just have to stick to the recommended repositories. 
 
Efficient: 
Developers have the convenience of running servers, training machine learning models, accessing remote machines, and compiling and running scripts from the same terminal window. 
 
Free: 
Linux is free (you can put it on as many systems as you like) and you can change it to suit your needs.
Cons
Learning Curve: 
Linux is not for everyone, there is a learning curve in switching to Ubuntu. To actually learn Linux efficiently would take a user one to several years.
 
No Tech Support:
Unlike Windows, there isn’t a dedicated tech support, so getting help for things is up to you. 
 
Designer Compatabilty:
Linux is not as user friendly as Windows or as ‘straight out of the box design’ As an example for design choices, Adobe hasn’t released any of its products to Linux users. So it’s impossible to run them directly. The Ubuntu alternative is a free software called GIMP. 
 
Gaming Capabilities: 
Most games aren’t available in Linux. But that’s not to say you can’t make it happen, it's just not as easy.
