Single-Board Computers
Raspberry Pi computers operate off of an SD card that needs to be "flashed" with an operating system. This process writes files to the SD card connected to a Windows, MacOS or Linux machine through a USB connection.
Raspberry Pi Imager
This is the official Raspberry Pi solution for flashing image files to the SD card, which is an integral part of the microcomputer ecosystem.

This option has the added benefit of allowing you to preconfigure Raspberry Pi OS and Linux related software, such as configuring Wi-Fi, changing the computer's host name, and enabling SSH for remote access. By default, Wi-Fi and Bluetooth are enabled.
