write about any 2 types of operating systems( special features, scope of use etc)
Answers
1. Batch Operating System –
This type of operating system does not interact with the computer directly. There is an operator which takes similar jobs having the same requirement and group them into batches. It is the responsibility of the operator to sort jobs with similar needs.
Advantages of Batch Operating System:
It is very difficult to guess or know the time required for any job to complete. Processors of the batch systems know how long the job would be when it is in queue
Multiple users can share the batch systems
The idle time for the batch system is very less
It is easy to manage large work repeatedly in batch systems
Disadvantages of Batch Operating System:
The computer operators should be well known with batch systems
Batch systems are hard to debug
It is sometimes costly
The other jobs will have to wait for an unknown time if any job fails
Examples of Batch based Operating System: Payroll System, Bank Statements, etc.
2. Time-Sharing Operating Systems –
Each task is given some time to execute so that all the tasks work smoothly. Each user gets the time of CPU as they use a single system. These systems are also known as Multitasking Systems. The task can be from a single user or different users also. The time that each task gets to execute is called quantum. After this time interval is over OS switches over to the next task.
Advantages of Time-Sharing OS:
Each task gets an equal opportunity
Fewer chances of duplication of software
CPU idle time can be reduced
Disadvantages of Time-Sharing OS:
Reliability problem
One must have to take care of the security and integrity of user programs and data
Data communication problem
Examples of Time-Sharing OSs are: Multics, Unix, etc.
