Cloud-based applications are software programs that run on the internet instead of being installed on your computer. This means you can access them from any device with an internet connection, like your laptop, tablet, or smartphone. Popular examples include Google Drive and Microsoft Office 365, which allow users to create and share documents easily without needing to download anything. These applications are hosted on remote servers, managed by companies like Amazon Web Services or Microsoft Azure. This setup not only saves storage space on your device but also ensures that your data is backed up and secure. Plus, updates happen automatically, so you always have the latest features.
