Computing Fundamentals: It Networking, Os & Vir... Apr 2026

Every device needs an IP Address so the network knows exactly where to deliver the data. 2. Operating Systems (OS): The Software Architect

If a computer is an island, networking is the bridge system. It’s the practice of linking computing devices together to share resources and data. Computing Fundamentals: IT Networking, OS & Vir...

These three don't work in isolation. A needs an Operating System to function, and it needs a Network to communicate with the outside world. Mastering these fundamentals is the "Level 1" for anyone looking to build, secure, or manage the technology of tomorrow. Every device needs an IP Address so the

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. It’s the practice of linking computing devices together

This is the secret sauce—a layer of software that sits between the physical hardware and the virtual machines (VMs), tricking each VM into thinking it has its own dedicated processor and memory.

The OS decides which apps get to use the CPU (the brain) and how much RAM (short-term memory) they receive.
