An operating system (OS) is a software program that manages the hardware and software resources of a computer. It acts as an intermediary between the computer's hardware and the applications that run on it, allowing the hardware and software to work together seamlessly. There are several different classes of operating systems, each with its own set of features and capabilities.

Single-user, single-tasking OS: This type of operating system is designed to run on a single computer and support only one user at a time. It allows the user to run one program at a time, and it does not support multitasking (the ability to run multiple programs concurrently). Examples of single-user, single-tasking operating systems include DOS (Disk Operating System) and CP/M (Control Program/Monitor).

Single-user, multi-tasking OS: This type of operating system is designed to run on a single computer and support only one user at a time, but it allows the user to run multiple programs concurrently. It does this by dividing the computer's resources (such as CPU time and memory) among the various programs, allowing each program to run for a short period of time before being paused to allow another program to run. Examples of single-user, multi-tasking operating systems include Windows and macOS.

Multi-user OS: This type of operating system is designed to run on a computer that is used by multiple users simultaneously. It allows multiple users to log in to the system and run their own programs, and it includes features such as file permissions and user accounts to control access to the system's resources. Examples of multi-user operating systems include Unix and Linux.

Real-time OS: This type of operating system is designed to support real-time applications, which are applications that require a quick response to events as they occur. Real-time operating systems are used in a variety of applications, such as aviation, military, and industrial control systems. They are designed to be extremely reliable and responsive, and they often have features such as preemptive scheduling (the ability to interrupt a running process to run a higher-priority process) and real-time interrupts (the ability to respond to external events immediately). Examples of real-time operating systems include VxWorks and QNX.

Embedded OS: This type of operating system is designed to run on a small, specialized device, such as a smartphone or a smart home device. It is designed to be lightweight and efficient, and it often has a small footprint (meaning it requires very little memory and storage space). Examples of embedded operating systems include Android and iOS.

In conclusion, there are several different classes of operating systems, each with its own set of features and capabilities. The class of operating system that is most suitable for a particular application will depend on the specific requirements of that application.

What is Operating System (OS)? Defintion and Functions

Operating systems were first developed in the late 1950s to manage tape storage. Note - The only purpose of this article is to tell you about operating system examples in very simple language. Audience Our operating system tutorial is designed to help beginners, professionals and GATE aspirants. So now Enjoy E-Learning with Takshila Learning. Device Management: — Device management keeps track of all devices. UNIX was developed in assembly language, but 1973 had been almost completely recoded in C, facilitating their development and migration to other hardware.

Mobile OS: Mobile operating systems are those OS which is especially that are designed to power smartphones, tablets, and wearable devices. Monitoring and controlling nuclear power stations, rocket launching systems, are examples of real time systems. It also provides mechanisms for synchronization and communication among processes. After this time interval is over OS switches over to the next task. Note: CentOS is another great Linux distribution. It is also a good source of antioxidants. Chrome OS is a Google operating system that focuses on the Chrome OS is a popular Linux-based operating system which is developed and designed by This operating system is a lightweight and efficient operating system that would work on low-end machines.

It should be mapped to absolute addresses and loaded inside the memory to execute a program. For example, the user can listen to music on the computer while writing an article using a word processing software. Classification of Operating Systems Operating systems can be classified as follows: Multi-user: is the one that concede two or more users to use their programs at the same time. File system that permits files to be recorded in a tree structure. It is a type of system software that is responsible for the smooth functioning of the computer system. The user can switch between the applications and also transfer data between them.

What are the types of Operating systems OS? The system is stable and secure, making it an appealing choice for businesses. It performs basic tasks such as recognizing input from the keyboard, keeping track of files and directories on the disk, sending output to the display screen, and controlling peripheral devices. The kernel is a critical component of the operating system that controls the hardware and computer functions. It manages the operations of both the memory and the CPU.

It can also be downloaded onto computers to allow them to run the same features available on the devices. Potential advantages and disadvantages of real-time operating systems include: Advantages Disadvantages They use device and systems maximally, hence more output. For example, in older systems, it takes about 10 microseconds in shifting one task to another, and in the latest systems, it takes 3 microseconds. Time-sharing systems were developed in the late 1950s and early 1960s for mainframes and minicomputers. While many programmers today are skilled in cross-platform programming, meaning the software they develop is capable of running on multiple platforms, there are, of course, still specific-OS developers, such as a Linux developer, a macOS developer or an Android developer.

Examples of Real-Time Operating Systems are: Scientific experiments, medical imaging systems, industrial control systems, weapon systems, robots, air traffic control systems, etc. Main memory is made up of a large array of bytes or words where each byte or word is assigned a certain address. The OS features a familiar interface and broad third-party app support at a reasonable price. There are more than one processors present in the system which can execute more than one process at the same time.

Types of Operating System OS are classified into the following types depending on their capability of processing Single User and Single Task OS: It is used on a standalone single computer for performing a single task. A typical desktop OS includes a shell program such as file management, a window manager, and often a built-in GUI or graphical user interface. The pros of FreeBSD are that it is fast, completely free, has good security that utilizes the ipfw firewall, and has a lot of tools available and owned by the FreeBSD Team. When software developers create applications, they need to write and compile them for a specific operating system. The time ensures that no process has control of the CPU without renouncing it.
