For computers to talk, they need rules. The most important is TCP/IP , which breaks data into small "packets," sends them across the web, and reassembles them at the destination. Computing Fundamentals: IT Networking, OS & Vir...

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 If a computer is an island, networking is the bridge system

You have Switches (connecting devices within one network, like an office) and Routers (connecting different networks, like your home to the Internet). The most important is TCP/IP , which breaks

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.
