How does Docker differ from traditional virtualization?

Не верно!

Docker uses software-level virtualization, which means that containers share the same underlying kernel as the host system, but have their own isolated file system and network stack. This provides a lightweight and efficient way to package and run applications.

What is the difference between a Docker container and a virtual machine?

Не верно!

Docker containers share the host operating system kernel, which makes them smaller, faster, and more efficient than virtual machines. They also use less resources and provide better performance.
