Virtualization and containers concept in Intro to Computing - Flowchart & Logic Diagram

Process Overview

Virtualization and containers let one computer run many separate environments safely and efficiently, like having multiple houses on one land.

Run applications

This flowchart shows the decision process between using virtual machines or containers based on hardware support, and how each runs applications.

Step-by-Step Trace - 8 Steps

Step 1: Start and check if hardware supports virtualization

Step 2: Decision: Is virtualization supported?

Step 3: If yes, create virtual machines (VMs)

Step 4: Install guest OS inside each VM

Step 5: Run applications inside VMs

Step 6: If no virtualization support, use containers

Step 7: Run applications inside containers

Step 8: End process

This diagram shows a host computer with hardware at the base. The hypervisor creates virtual machines each with their own guest OS and apps. The container engine runs containers that share the host OS kernel but isolate apps.

Flowchart Quiz - 3 Questions

What does a virtual machine (VM) include that a container does not?

A A full guest operating system

B Shared OS kernel

C Direct hardware access

D No isolation

Key Result

Virtual machines provide full OS isolation using hardware virtualization, while containers share the host OS kernel for lightweight, efficient application isolation.
