Daemon: A background process that runs in the background on each emulator or device instance.
Server on the development machine: This is a background process that runs on the development machine and manages the communication between the client and server.
On starting adb, the client first checks whether there is an adb server process already running. If there isn't, it starts the server process. When the server starts, it binds to the local TCP port 5037 and listens for commands sent from adb clients—all adb clients use port 5037 to communicate with the adb server.
