Not all devices support fastboot, but many do. It is a good alternative to the recovery mode for doing installations and updates that can be used to re-flash partitions on android smartphones. Fastboot mode can start on your device even before Android loads and can even run when Android isn't installed at all, fastboot mode is useful for updating firmware quickly, without having to use a recovery mode. In fact, it's the most preferred way to initially install stock and custom recovery image on many android devices. Fastboot can also be used for developer operations like unlocking the bootloader of Google's Nexus devices.
