What is an Operating System?

Imagine this: you turn on your smartphone or computer, and everything works perfectly. Have you ever wondered how this is possible? The key lies in understanding “What is an Operating System.” An Operating System is the behind-the-scenes maestro that orchestrates all the hardware and software on your device, ensuring smooth operation. But what functions does it perform, and why is it so important? The Operating System is the foundation of your digital experience. It manages memory, processes, security, and user interfaces. Without it, your favourite applications wouldn’t run, and your device would be in disarray. So, what exactly is an operating system and how does it keep your digital life in order? Let’s explore its intriguing realm and discover the magic that keeps everything running smoothly.

What is an Operating System?

A type of system software known as an operating system (OS) is responsible for managing all of a computer’s resources. It serves as an interface between the Hardware and Software, managing various components of the computer, including input and output devices. It is designed to oversee the overall resources and operations of the computer efficiently.

All other programs on the computer, including application programs and system software, are controlled and monitored by it. Examples of Operating Systems include Windows, Linux, macOS, Android, and iPhone Operating System (iOS).

How Does an Operation System Work?

Once installed, an Operating System depends on an extensive library of device drivers to customise its services for the specific hardware environment. For instance, any application might make a standard call to a storage device. This call is received by the operating system (OS) and converted by the appropriate driver into the actions or commands required by the computer’s underlying hardware. A comprehensive platform for identifying, configuring, and managing the following is provided by the Operating System:

a) A wide range of hardware parts, including processors.

b) Computer memory management and memory devices.

c) Chipsets.
d) Storage solutions.
e) The capabilities of networking f) Port communication interfaces, such as Video Graphics Array (VGA), High-Definition Multimedia Interface (HDMI), and Universal Serial Bus (USB).
g) Subsystem interfaces, such as Peripheral Component Interconnect Express (PCIe).
Operating System Types Types of Operating Systems can be classified based on various criteria, such as the number of users, the number of tasks, the type of hardware, the type of interface, etc. Some of the common types are:
1) Batch OS
A Batch Operating System processes tasks in groups rather than interacting directly with the computer. It organises similar tasks into batches for efficient processing and quicker response times. This system is well-suited for lengthy and repetitive tasks, such as managing payroll, data entry, and bank statements.
Users prepare their tasks offline and submit them to an operator to prevent slowing down the device.
2) Time-sharing or Multitasking OS
The Time-sharing Operating System, also known as a multitasking OS, works by devoting a specific amount of time to one activity and frequently switching between them. Unlike the batch system, the time-sharing system allows users to complete their work simultaneously.
Multics and Unix are two examples of operating systems that share time. These systems allow many users to be distributed across various terminals to minimise response time. A deeper comprehension of UNIX’s Types of Shell can also enhance the user experience by enhancing the way commands are processed and managed in these environments.

A Distributed Operating System is based on autonomous but interconnected computers communicating with each other via communication lines or a shared network. Each autonomous system has its own processor, which may or may not have the same size or function. These Operating Systems are often used for tasks such as telecommunication networks, airline reservation controls, and peer-to-peer networks. A distributed Operating System serves multiple applications and users in real time, with data processing distributed across the processors.
4) Operating System for the Network Network Operating Systems are installed on a server, offering customers with the capability to control information, user companies, and packages. This Operating System enables customers to access and share files and devices which include printers, security software, and other packages, usually in a local region network. Examples of network operating structures include Microsoft Windows or Linux, and macOS X.
5) Real-time OS
Real-time working systems (RTOS) are designed to satisfy strict timing necessities, making them ideal for programmes that require instant and unique responses. They are generally utilised in regions which include clinical experiments, scientific imaging, robotics, and air traffic control. RTOS may be categorised into hard real-time systems and soft actual-time systems.
Hard actual-time structures are used in programs with stringent time constraints, ensuring that vital duties are completed in the distinctive time body. Soft real-time structures prioritise vital obligations over others however do not have equally strict timing necessities.
6) Mobile OS
Mobile Operating Systems, such as Android OS, Apple iOS, and Windows Mobile OS, run exclusively on small devices like smartphones, tablets, and wearables. These systems combine the features of a personal computer with additional features useful for handheld devices.
Mobile Operating Systems start when a device is powered on to provide access to installed applications and manage wireless network connectivity.
