Which containers are used by Docker severs?

The correct answer is: C. Linux

Docker is a software platform that uses OS-level virtualization to deliver software in packages called containers. Containers are isolated from one another and bundle their own software, libraries and configuration files; they can communicate with each other through well-defined channels.

Linux is an open-source operating system that is widely used on servers. It is also the operating system that Docker is built on.

Windows, Android and Mac are all operating systems that can be used to run Docker containers, but they are not the operating systems that Docker servers use.

Here is a brief explanation of each option:

• Windows: Windows is a proprietary operating system developed by Microsoft. It is the most popular operating system for personal computers, but it is not as widely used on servers as Linux.
• Android: Android is a mobile operating system developed by Google. It is the most popular mobile operating system in the world, but it is not used on servers.
• Linux: Linux is an open-source operating system that is widely used on servers. It is also the operating system that Docker is built on.
• Mac: Mac is a proprietary operating system developed by Apple. It is the most popular operating system for personal computers in the United States, but it is not as widely used on servers as Linux.
