In computing, "mirroring" is the process of creating an exact replica of data or a screen for purposes like data redundancy, backup, or displaying content on multiple devices. Common examples include disk mirroring, where data is copied to two or more drives for reliability (often in RAID 1 configurations), and screen mirroring, which wirelessly displays one device's screen onto another, like a phone onto a TV. Another form is a mirror site, which is a copy of a website hosted on a different server to improve performance or availability.

Types of mirroring

Disk Mirroring: This is a data storage technique where data is written to multiple physical disks simultaneously. It's a key feature of RAID 1 (Redundant Array of Independent Disks), which protects against a single disk failure by creating a real-time, identical copy of the data.

Screen Mirroring: This technology duplicates the content of one screen onto a second screen, such as a smartphone mirroring its display to a TV. It is used for sharing content like videos, photos, and presentations with a larger audience or for a better viewing experience. This is often done wirelessly over Wi-Fi but can also be achieved with wired connections like HDMI.
