What is office365?

Office 365 is Microsoft’s subscription‑based bundle of cloud‑delivered productivity tools. It includes familiar programs like Word, Excel, PowerPoint, and Outlook, plus services such as OneDrive (cloud storage), Teams (chat and video), SharePoint (intranet and file sharing), and many others that you can use on a PC, Mac, tablet, or phone.

Let's break it down

  • Continuous updates: New features and security patches are delivered automatically, no manual installs needed.
  • Admin & security: Centralized admin console, multi‑factor authentication, data loss prevention, compliance tools.

Why does it matter?

Because it lets people work from anywhere on any device while keeping files in sync and up‑to‑date. The subscription model spreads costs over time, guarantees you always have the latest version, and provides built‑in security and backup that many small organizations could not afford on their own.
