ADB is a client-server program, and there are three components that make up the entire process. ADB stands for “Android Debug Bridge,” and it is a command line tool that is used to communicate with a smartphone, tablet, smartwatch, set-top box, or any other device that can run the Android operating system (even an emulator).
Client, the computer you have connected to your Android device.
Daemon (also known as adbd), and this is a service that is currently running on both the computer as well as the Android device and allows the latter to accept and execute commands.
Server, a piece of software that actually manages the communication between the client and the daemon. It’s the server that is running as a background process on your computer that sends those command to the daemon.
