Hi qt,
Thank you for reaching out to us on the Microsoft Q&A platform.
Microsoft 365 used to be called Office 365. It contains a number of great applications such as Word, Excel, PowerPoint, Outlook, OneNote, SharePoint, and Exchange. It also hosts services such as OneDrive and Teams, which are used in file storage in the cloud as well as working together with people.
You can use the free online versions of Word, Excel, and PowerPoint, but with limited features. You'll also get 5 GB of storage on OneDrive if you sign up for a free Microsoft account.
If you would like to use the full versions of these apps on your computer and unlock more features, then you'll need to sign up for a subscription plan. There are two subscription plans:
Microsoft 365 Family: This allows sharing it with up to 5 others; each gets their own 1 TB of OneDrive storage.
Microsoft 365 Personal: This is for just one person, but the plan does include the full desktop applications and 1 TB of storage.
