Instead of buying 10 servers that each run at 10% capacity, you buy one powerful server and run 10 virtual ones on it.

Whether it’s the visual icons of Windows/macOS or the text-based commands of Linux , the OS provides the bridge between human intent and machine action. Computing Fundamentals: IT Networking, OS & Vir...

You have Switches (connecting devices within one network, like an office) and Routers (connecting different networks, like your home to the Internet). It allows you to run multiple "computers" on

Virtualization is the process of creating a software-based (virtual) version of a computer, rather than a physical one. It allows you to run multiple "computers" on a single physical machine.

The OS is the "manager" of the computer. Without it, you’d have to write manual code just to move your mouse or save a file.

This is the foundation of the Cloud. When you use AWS or Google Cloud, you aren't renting a whole building; you're renting a "slice" of a server via virtualization. Why the Trio Matters
