Types of Operating Systems (OS):
There are several types of Operating Systems which are mentioned below.
- Batch Operating System
- Multi-Programming System
- Multi-Processing System
- Multi-Tasking Operating System
- Time-Sharing Operating System
- Distributed Operating System
- Network Operating System
- Real-Time Operating System
Batch Operating System:
- Batch operating systems automate and execute repetitive tasks in batches without user interaction.
- They were commonly used in early mainframe environments for processing large volumes of data sequentially.
Examples include IBM OS/360 and UNIVAC Exec 8.
Advantage of Batch Operating System:
1. Efficient resource utilization, ideal for processing similar jobs without
manual intervention.
2. Reduces user interaction overhead by automating the execution of multiple
tasks in a batch.
Disadvantage of Batch Operating System:
1. Lack of Interactivity: Batch systems offer limited user interaction,
making them unsuitable for real-time or interactive applications.
2. Inefficient for Diverse Tasks: They are less efficient when dealing with
diverse job types and variable workloads.

Multi-Programming System:
- Multi-programming systems allow multiple programs to be loaded into memory simultaneously.
- While one program is executing, others are waiting to run, making efficient use of CPU time.
- Enhances CPU utilization and throughput.
Advantage of Multi-programming Operating System:
1. Improved CPU Utilization: Multi-programming OS allows for concurrent execution of multiple programs, maximizing CPU usage and enhancing overall system efficiency.
2. Enhanced Throughput: It increases system throughput by reducing idle time, ensuring continuous task execution and faster job completion.
Disadvantage of Multi-programming Operating System:
1. Complex Resource Management: Managing multiple processes simultaneously can be challenging, leading to potential resource conflicts and system instability if not handled properly.
2. Increased Overhead: Context switching between multiple processes consumes system resources and introduces overhead, which can affect overall performance.
