A Look Inside Docker & Its working.
Docker is a tool to run containers and build images, providing a CLI and API for container management. Containers are isolated entities that include applications and their dependencies. Docker images define container contents and operation. The Docker CLI translates commands into API requests for the Docker daemon, which manages container and image operations via ContainerD and runc. Key Linux features, Namespaces and C-Groups, provide process isolation and resource allocation within containers.

Why Linux is Better Than Windows 11
Linux offers several advantages over Windows 11, such as cost savings, better performance, enhanced security, and greater customizability. Many PCs are not compatible with Windows 11 due to strict hardware requirements, but Linux can run on older hardware effectively. Linux's open-source nature leads to faster bug fixes and better privacy since it doesn't collect user data like Windows. Additionally, Linux's low system overhead provides better performance for gaming and other applications.
