Time-sharing refers to sharing a computing resource among many users by multitasking.Because early mainframes and minicomputers were extremely expensive, it was rarely possible to allow a single user exclusive access to the machine for interactive use.


But because computers in interactive use often spend much of their time idly waiting for user input, it was suggested that multiple users could share a machine by using one user's idle time to service other users.


Similarly, small slices of time spent waiting for disk, tape, or network input could be granted to other users. Computers capable of providing time-sharing services would often operate in batch mode overnight.


Batch os is os which analyzes your i/p and groups them into batchs .That is data in each batch is of similar characteristics.And then it performs operation on each individual batch.

Batch operating system are those where we collect similar kind of process make a batch and than submitted to processor to process.
Time sharing where processor jumps between process when a process in its input
session or output session processor jumps to the process which is in process
phase.
