Answer: they cannot carry information directly.
Signals are useful in
inter process communication (IPC) in a limited way. They are system messages
that are sent from one process to another. Signals are not used to transfer
data but are used for remote commands between processes.
One of the methods of
IPC is using signals, which are asynchronous notifications sent to a process by
the operating system, another process, or itself.
Signals can be used to
inform a process about different events, such as user input, termination,
suspension, or errors.
One of the main
advantages of using signals for IPC is that they are simple and efficient.
Signals do not require any data structures, buffers, or queues to store or
transmit information.
One of the main
disadvantages of using signals is that they are unreliable and unpredictable.
