+# Q1 Docker Containers Vs Vms
+Docker containers and virtual machines (VMs) are both technologies used for virtualization, but they operate at different levels of abstraction. VMs virtualize the entire hardware stack, allowing multiple operating systems to run on a single physical machine. Each VM includes its own guest OS, consuming more resources and requiring a hypervisor for management. In contrast, Docker containers share the host OS kernel, making them lightweight and efficient. They encapsulate applications and their dependencies, ensuring consistency across different environments. This makes containers faster to start, use fewer resources, and allows for easier scaling. Overall, Docker containers are well-suited for application deployment and microservices architectures, while VMs are better suited for running multiple, diverse applications on the same host.

+Answer1:
+Virtual machines: create a complete virtualized environment for each application, including a separate operating system, kernel, and hardware resources. This makes VMs very isolated and secure, but it also makes them more resource-intensive and slower to start up.
+
+Docker containers: share the host operating system kernel and resources, but each container has its own isolated file system, processes, and network capabilities. This makes containers much more lightweight and faster to start up than VMs, but it also means that they are not as isolated or secure.

+where:
+-d: Runs the container in detached mode, meaning it runs in the background.
+--name assignment-2-I20-0792: Specifies the name of the container.
