Types of Operating System
There are primarily 5 types of Operating Systems –
1. Batch Operating Systems: In this type of Operating System, the similar tasks to be completed are grouped together into units called batches with the help of an operator. These batches are then executed one by one.
This system saves a lot of time by performing several similar tasks at once without reloading the system each time. This particular kind of operating system can be shared among several users.
However, the user needs to manually intervene between every other batch to continue the execution process. Not much of the CPU is utilized due to the amount of time taken for loading and unloading being much higher than the program execution.
Knowing about the batch processing system is crucial to understanding how to learn Operating Systems.
2. Time Sharing Operating Systems: In Time Sharing Operating Systems, the time is shared between two or more tasks, which implies several processes are being executed simultaneously with the aid of the Time-Sharing concept.
In this concept, a time called quantum time is decided upon to execute the processes. The process can continue only until that specific period, after which other processes will start to run. In the next cycle, the first process will begin again with the same time allotted.
The CPU will be fully utilized, and each process will get an equal chance to execute. However, this process is disadvantageous when a particular process has a higher priority. Therefore, the higher priority process shall not be executed first in this type of system.
3. Embedded Operating Systems: Embedded Operating systems are not designed for computers. They are designed for electronic devices and perform only specific tasks like central heating systems or GPS trackers.
These operating systems are dedicated to only one kind of task and therefore are super fast, consume less memory and resources, and are cost-efficient.
However, the limitations are that it can perform only one task and it is not easy to update/upgrade these types of operating systems.
4. Distributed Operating Systems: To fully understand how to learn Operating Systems, you need to know about Distributed Operating Systems.
In a Distributed Operating System, several different systems have their own resources like primary and secondary memory and processing units.
These systems are connected to each other through a shared communication network and have access to each other’s data as well. One system can perform its own task without being burdened by other tasks.
In this process, some hindrance in any one of the processes will not affect the other processes, and the load is evenly distributed on the computer, increasing its efficiency.
However, in order to make the data secure, extra measures will be needed, and the communication network needs to be stable at all points of time.
5. Real-Time Operating Systems: In Real-time Operating Systems, the execution of data is performed in real-time; that is, the program is executed as soon as it comes without any sort of delay.
It is basically the same as the time-sharing OS with the concept of clock interrupt. So to process a large amount of data, the fastest way out is to use a real-time operating system.
In this type of system, the devices and resources are utilized to their maximum capacity, and the chance of an error occurring is almost negligible, but the time-complexity of the Real-Time OS algorithm is greater than any other OS algorithm.
Real-time Operating systems are further divided into:
- Hard Real-time
- Soft Real-time
If you want to know the right way on how to learn about Operating Systems, you need to make sure you understand the types of Operating Systems well.
