What is ADB?

ADB stands for “Android Debug Bridge”. It is necessary and essential to establish the connection between computer and android device. This tool will allows you to send wide array of terminal commands—including but basic Linux shell commands, plus some specialty developer commands—to your phone at just about any time (as long as you have debugging enabled on your phone). You can send commands while the phone is turned on and booted, or even when it’s in recovery mode. While ADB is often used in conjunction with rooting or modifying your phone, you can use ADB to send terminal commands to unrooted devices as well.

What is Fastboot?

When you need to modify your phone’s firmware, fastboot is the tool you need. This allows you to send commands to the bootloader, which means you can flash/modify things like custom recoveries. You can’t flash whole ROMs with it, but it’s helpful for many things that ADB can’t do. Fastboot isn’t enabled for all phones, so you may have to check your specific device.
