+Q1) Explain Docker Containers vs VMs
+Docker containers represent the active instances of Docker images. They utilize OS-level virtualization, with the sharing of the OS kernel. On the other hand, virtual machines (VMs) employ hardware-level virtualization. Containers include their own libraries, while VMs require manual installation of all components. Containers offer flexible compute resources, while VMs are characterized as static computing machines.
+Q2) Write command to create a docker container in detached mode with name assignment-2-<ROLL_NUMBER> running on host port 9090 and container port 80 using image nginx with version 1.24.0 on a custom network named assignment-2
+docker container run -d --name assignment-2-I20-0933 -p 9090:80 --network assignment-2 nginx:1.24.0
