Hello,

The main reason is that the operating system design did not allow the user to interact with the running jobs. Later Kernel were designed in such a way that they provided the facility of interactivity along with multiprogramming.
(b) A signal is an event to get the attention of a process. . A signal can be send from one process to an other process. For example if a file exceeds limits then the process may be asked to produce the output until the file size is increased. Similarly you can use ctr+z command on Linux shell to stop the running process.
