Question

Write short notes in Types Of OS? ​

Answer 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.

Answer 2

Short notes on the types of OS:

1. Batch Operating System – There is no direct interface between this operating system and the computer. There is a person who organizes linked jobs into batches based on their requirements. The operator is responsible for grouping jobs with comparable criteria.
2. Time-Sharing Operating Systems – So that everything goes well, each task is assigned a specific amount of time to perform. Each user gets CPU time because they are on the same system. Another name for these systems is multitasking systems. A single person or a group of people may initiate the task.
3. Distributed Operating System – A set of independent networked computers communicates with each other using a shared communication network. The memory and processor of independent systems are separate. These systems are known as loosely connected systems or dispersed systems.
4. Network Operating System –These systems, which run on a server, manage data, users, groups, security, applications, and other networking functions. These operating systems provide shared access to files, printers, security, programs, and other networking features via a small private network.
5. Real-Time Operating System – Real-time systems employ these operating systems. It takes a short amount of time to process and respond to information. This duration of time is known as response time. Real-time systems are utilized where severe timing limitations exist, such as in missile systems, air traffic control systems, robots, and so on.
