What is Operation System?
Every computer or computable device runs on an operating system. It is just like software that runs on every portable device. The target is to manage the computer's memory and processes. The operating system also controls its software and hardware. It permits the user to communicate with the computer without knowing the machine's code.
The operating system is needed to execute application programs and services. It acts as a platform to achieve better communication between application software and computer hardware. For example - UNIX, MS-DOS, MS-Windows, and Mac OS.
Evolution of Operating System
In 1960, the first operating system (OS) was developed with uncomplicated features. At that time, OS was automatically running several operations at a contemporary speed. The operating system could perform several processes after 1960. Those are I/O intervenes, spooling, parallel processors, buffering, document sorting, run-time archives, group processing, multi-tasking, link filling, and many more. The hardware was added to the OS after 1960.
Types of Operating System
The operating system got upgrade with innovative technologies with respect to time. Our operating system assignment experts are considered with the operating system types.
1. Real-Time
This type of operating system is a multitasking operating system. It is basically used to execute real-time software. They are dependent on time-sharing as well as event-oriented designs. Such OSs react quickly in a deterministic process because of the performance of major task scheduling algorithms. Real-time is also divided into two more categories. Those are given below:
● Event Oriented Real-Time Operating System: it is exchanged based on priority and external factors.
● Time-Sharing Real-Time Operating System: it is exchanged based on their clock hinders.
Multi-User
In a multi-user operating system, numerous operators can run a single computer simultaneously. It is a time-sharing structure and that’s why operators can obtain a single machine simultaneously.
Distributed Operating System
Many machines are connected to make a single network in the distributed operating system. The set of computers perform binding jobs in the OS.
Template
It means that the computer-generated machine acts as a guest operating system. It is rather implemented as a device for executing various computer-generated systems. This type of operating system is very useful in virtualization and cloud operations.
Embedded
The embedded operating system is very compact and performs on particular hardware-oriented components.
Purpose of Operating System
Operating System is always responsible for various operations. Those are given below
1. Memory Organization
Computer Memory has two parts: main memory and secondary memory. CPU is directly accessing the storage process. Hence, the main memory is very important. The storage process is augmented by main memory.
Main memory is also responsible for long bite arrays that comprise important address locations. The operating system handles both the processes of main memory ad primary memory. A list of tasks that are performed by the operating system are given below:
● It tracks both the memory parts: primary memory used parts and not in used parts.
● It allocates the memory to it when the processor request for memory allocation.
● It decides the memory percentage that is to be allocated to the processor in the case of a multi-programming system. To know more about the domain, talk with our operating system assignment help experts.
● The operating system de-allocates the memory when the task is terminated.
● It calculates the interruption time and keeps it. It is achieved through service requests and service response.
2. Processor Organization
Operating System performs various on Processor. Those are given below:
● The operating system follows the status and activities of the processor using the traffic control program. It also decides that which processor will take the process.
● As per the requirement, it also de-allocates processes from the processor.
3. File Management
File management plays a vital role in the operating system to navigate files. Files are arranged into several paths or directories. Hence, it is easier to use and traverse. File management follows several functions to perform or manage Operating System. Those are given below:
● On the behalf of stored data, it keeps a record of the various points. Those are status, usage, location, and more.
● It decides two major operations. Those are which programmable resources should allocate when the data or resources are not in use, and make sure to de-allocate them.
● It has the ability to store strong passwords and a security firewall. By which, it is used to avert prohibited access from malicious codes.
4. Device Organization
To perform network communication, devices use their own drivers. It has a major role in the operating system. Those are discussed below:
● OS uses an Input/ Output controller to track all the device’s records
● It settles that which program process will be allocated to which processor
● It ensures devices resourceful allocation
● Depending on the system requirement, it de-allocates the devices.
● It coordinates with other components. Those are interpreters, compilers, and assemblers.

Operating System Questions and Answers
It is a vast part of computer science. Therefore, it contains numerous questions. Some of them are discussed below:
1. What is the main purpose of an operating system?
OS focuses on two main purposes. Those are given below:
● It is designed by maintaining its computational pursuits to make sure that a computer system works better.
● It presents an ecosystem for program development and execution.
2. What are the different operating systems?
● Batched OS
● Distributed OS
● Timesharing OS
● Multi-programmed OS
● Real-time OS
3. What is kernel?
The Kernel is the core part of a computer operating system. It provides all basic co-operations for all OS parts. Hence, it is very important.
4. What is the difference between micro kernel and macro kernel?
Micro-kernel works on minimal production by affecting services for the operating system. With the help of this kernel, the processor of the OS executes all other services. On the other hand, Macro Kernel is a set of micro and monolithic kernels.
What is the difference between process and program?
Program is nothing but a code or set of instructions that need to be executed. It is known as a process when it is running or executing.
What is the advantage of a multiprocessor system?
We will get a substantial addition in throughput as more processors are increased. It is a cost-effective process. The reason is that they can receive resources. So, the overall authenticity raises.
