What the Internet Is
The internet is a global network of connected computers and devices that communicate using standard protocols. It enables websites, email, cloud storage, video calls, streaming, and online collaboration.
Web Browsers
A browser is software used to access websites and web applications. Common browsers include Chrome, Edge, Firefox, and Safari. Tabs, bookmarks, history, downloads, and privacy settings are all important practical browser features.
Search Engines and Information Literacy
Search engines help users find information quickly, but students should also learn how to judge source quality, avoid misinformation, and refine searches with better keywords.
Email Basics
Email is still a core communication tool in education and business. Users should understand inboxes, attachments, spam, phishing risks, and professional email habits.
Cloud Basics
Cloud services store or process data on remote systems accessed over the internet. Examples include cloud storage, web applications, online collaboration tools, and remote backups.
Advanced Perspective
Advanced learners should understand the difference between local and cloud storage, browser-based applications, identity and sign-in systems, and the basics of online privacy and account management.
