Operating System is like the heart of a computer. It is a system software responsible for controlling other software and different hardware. It is the bridge that gap between software and hardware.
Batch Operating System
The second generation of computers used Batch Operating System as the first operating system. The batch Operating system does not interact with the computers directly but instead took the input in a punch card. Each of these punch cards has a different form of data that was executed by the operating system in different batches, for example- payroll systems.
A single batch can be shared amongst multiple users.
Lesser idle time
Better CPU utilization.
Difficulty in debugging
Falls into an infinite loop in case a job fails.
Distributed Operating System
One of the latest advancements in the cyber world, using this OS various autonomous computers can communicate with each other. It is a collection of independent, interconnected, networked, separate computational nodes (separated at the physical level) for example- Locus.
Being independent, failure in one system will not affect the functioning of the other systems.
Reduced delay in the data processing.
If the main network fails, then the OS becomes useless.
Real-Time Operating System
These types of OS are designed to serve those applications which carry out their task in real-time, without any potential buffer delays. It is further classified into two types- Hard Real-Time Systems and Soft Real-Time System. Examples- Medical Imaging Systems, Weapons and robotics systems, etc.
Maximum consumption of the system and connected devices, hence greater output.
Most efficient memory allocation.
Many complex algorithms involved.
Less efficient when it comes to task switching.
What really surprises me is that computer science has become so theoreticized. We read about types of operating systems as if it really matters. But when I need to fix my problems with Windows, nobody can help.
Right. The same happens here. All my colleagues use Linux or Mac, and when I had Win button problem on my keyboard, all those so-called experts were spreading their hands. So I had to google that and found this link by myself. And fortunately, those tips helped, besides they were absolutely free. So never again will I ask my sassy co-workers!
