What is Operating System and its types
What is Operating System and Its Type – Today we will talk about Operating System in this blog and tell you what is Operating System and Types of Operating System. What is operating systems? An operating system (OS) is software that acts as an interface between the user and the components of the computer hardware. How many types of operating systems are there? There are many valid types of operating systems like – batch operating system, Multi-tasking and time-sharing operating system etc. About whom we will tell you today. So let’s talk about what is operating system and its types.
What is operating system?
An operating system is a program that is initially loaded into a computer through the boot program and, once loaded, administers the computer and all application programs. Application programs use the operating system by requesting services through a defined application program interface (API). In addition to these, users can interact directly with operating systems through a user interface, such as a graphical UI (GUI) or command-line interface (CLI).
An operating systems (OS) is software that acts as an interface between the user and the components of the computer hardware. Every computer system must have an operating systems to run other programs. Like- Browsers, Notepad Games, MS Office, etc. applications require some environment to run and perform their functions.
Operating systems help you communicate with the computer without knowing the correct way to speak the computer’s language. Without operating systems it is not possible for the user to use any mobile or computer device. now we will discuss types of operating system.
Types of Operating system
Batch operating system
Some computer procedures are very time consuming and very long. To speed up similar processes, all jobs requiring a simple type are batched together and run as a group. The user never interacts directly with the computer of a batch operating system. In this type of operating system, each user does his work on an offline device like a punch card and submits that work to the computer operator. This is a type of operating system.
Multi-tasking and time-sharing operating system
Time-sharing operating systems enable people located at different terminals to use the same computer system at the same time. Processor time that is shared among multiple users is called time sharing.
Real time operating system
The time lag for a real-time operating system to respond to and process input is very short. For example: Military Software System, Space Software System. This is a type of operating system.
Distributed operating system
Distributed systems use multiple processors located on multiple machines to provide extremely fast computation to their users.
Network operating system
This operating system runs on a server. Network operating systems provide the ability to provide services for administering applications, data, groups, security, users, and other networking functions.
Mobile operating system
Mobile operating systems are systems specifically designed to run tablets, smartphones, and wearables. This is a type of operating system
Some of the most popular mobile operating systems are Android and iOS, but others include Blackberry, watchOS, and Web.
Advantage of Operating System
- Abstraction allows you to hide the details of the hardware.
- Very easy to use with GUI.
- It provides an environment in which the user can execute the program
- The operating system should ensure that the computer system is convenient to use.
- The operating system acts as an intermediary between the hardware and application components.
- Provides computer system resources in an easy-to-use format
- Acts as an intermediary between all the software and hardware of the system
Features of Operating System
- Operating systems provides a that a platform on which applications could be run.
- Operating system Supports networking by handling memory management and CPU scheduling.
- Operation system also provide file system abstraction.
- Operating system also provide user interface.
- Operating system also offers system and utility services.
- Operating system is supports the creation of applications
Components of Operating System
Now, the operating system has two parts that work together to carry out the following functions:
Shell controls user communication. It is the OS’s outer part and controls how users and the operating system interact by:
- Collecting user’s opinion
- Interpreting the operating system’s input
- Handling the operating system’s output.
Shell offers a means of interacting with the OS through either user input or shell scripts. A series of system commands that are saved in a file is referred to as a shell script.
Functions of Operating System
- Processor Management: An operating system arranges the tasks that the processor must complete by assigning them to it and making sure that it has enough time to complete each task.
- Memory Management: An operating system controls the allocation and release of memory to different processes and makes sure that no process uses memory that has been allotted to another.
- Device Management: An OS controls the operation of these input-output devices. It responds to the requests made by these devices, carries out the requested task, and then receives requests again.
- File Management: An operating system maintains orderly records of information pertaining to the production, deletion, transfer, copy, and storage of files. By preventing illegal access, it also upholds the confidentiality of the information contained in these files, including the file directory structure.
- Security: The operating system offers a number of methods that guarantee the security and integrity of user data. To safeguard user data, the following security methods are employed:
- protection from login-based unlawful access.
- By keeping Fire fall operational, protection against incursion is provided.
- defending the system memory from unauthorized access.
- displaying notifications about security holes in the system.
- Error Detection: The operating system periodically scans the device for any external threats or malicious software activities. Additionally, it looks for any damage to the hardware. For the user to be able to respond appropriately to any system harm, this process shows a number of alarms.
- Job Scheduling: The operating system chooses which apps should run in what order and how much time should be allotted to each one under a multitasking OS where numerous programmers run concurrently.
