 The client programs that aggregate the desired system data are sending them to the daemon process.
 This is done via a simple packet, `measurement_t` which is defined in [`common/include/measurement.h`](common/include/measurement.h).
 It holds the data of a measurement, which can be an integer, unsigned integer, float or double, the type of the data and an id that identifies the sender.
-The id is an `uint8_t` and should be unique for each client that sends data, so the maximum amount of clients is 255.
+The id is an `uint8_t` and should be unique for each client that sends data, so the maximum amount of clients is 256.
 
 The packet is sent via a message queue, which is created by the daemon process.
 Clients will wait until the message queue is created and then send their data to the daemon.
