If no Slots are connected, the message „is lost in the wild“. So a connection between Signals & Slots is like a TCP/IP connection with a few exceptions, but this metaphor will help you to get the principle. A Signal is an outgoing port and a Slot is an input only port and a Signal can be connected to multiple Slots.

Deeper. Widgets emit signals when events occur. For example, a button will emit a clicked signal when it is clicked. A developer can choose to connect to a signal by creating a function (a slot) and calling the connect() function to relate the signal to the slot. Qt's signals and slots mechanism does not require classes to have knowledge of each other, which makes it much easier to develop

From the other hand, Qt's implementation of signal-slot mechanism has its own limitations - it does not support slot parametrization and usage of signals and slots in interfaces.

Implementing my own signal slot mechanism using C++11 I programmed in C# and I used the Qt framework. Both of them have their own signal slot mechanism which are really powerful. I looked at several implementations in C++ and based on what I learnt from those sources, I started to implement my own version to better understand how these could work under the hood.
