What is the difference between Linux server and Windows Server? Why do some companies use/prefer Linux server?

Hello, this is not really a question belonging to the Microsoft forums. Most people here work only with Microsoft systems so how should they answer this question. Please use Linux forums for Linux related questions and ask here about Windows server related questions in detail. Thank you for understanding.Best regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.
