User could not interact with a multi programmed batched computer system

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.
