OS accessibility features are built into the operating system to help people with disabilities use the device more easily. Screen readers read on-screen text aloud, high-contrast mode sharpens the visual contrast to aid visibility, magnification enlarges portions of the screen for easier reading, and voice control lets you operate the device with spoken commands. These tools specifically address barriers in how information is presented and how the device is controlled, making technology usable for those with vision or motor impairments. The other options focus on security or system maintenance—firewall configuration and antivirus scans protect and manage safety, disk cleanup utilities tidy up storage, and automatic backups protect data. While important, they don’t provide features that assist users with disabilities, so they don’t fit the idea of OS accessibility features.
