An Operating System (OS) is a software that acts as an interface between computer hardware components and the user. Every computer system must have at least one operating system to run other programs. Applications like Browsers, MS Office, Notepad Games, etc., need some environment to run and perform its tasks. The OS helps you to communicate with the computer without knowing
how to speak the computer’s language. It is not possible for the user to use any computer or mobile device without having an operating system. Following are the Operating System examples with the latest Market Share Following are the popular types of OS (Operating System):
Batch Operating SystemSome computer processes are very lengthy and time-consuming. To speed the same process, a job with a similar type of needs are batched together and run as a group. The user of a batch operating system never directly interacts with the computer. In this type of OS, every user prepares his or her job on an offline device like a punch card and submit it to the computer operator. Multi-Tasking/Time-sharing Operating systemsTime-sharing operating system enables people located at a different terminal(shell) to use a single computer system at the same time. The processor time (CPU) which is shared among multiple users is termed as time sharing. Real time OSA real time operating system time interval to process and respond to inputs is very small. Examples: Military Software Systems, Space Software Systems are the Real time OS example. Distributed Operating SystemDistributed systems use many processors located in different machines to provide very fast computation to its users. Network Operating SystemNetwork Operating System runs on a server. It provides the capability to serve to manage data, user, groups, security, application, and other networking functions. Mobile OSMobile operating systems are those OS which is especially that are designed to power smartphones, tablets, and wearables devices. Some most famous mobile operating systems are Android and iOS, but others include BlackBerry, Web, and watchOS. Functions of Operating SystemSome typical operating system functions may include managing memory, files, processes, I/O system & devices, security, etc. Below are the main functions of Operating System: Functions of Operating SystemIn an operating system software performs each of the function:

What is Kernel in Operating System?The kernel is the central component of a computer operating systems. The only job performed by the kernel is to the manage the communication between the software and the hardware. A Kernel is at the nucleus of a computer. It makes the communication between the hardware and software possible. While the Kernel is the innermost part of an operating system, a shell is the outermost one. Introduction to KernelFeatures of Kernel
Types of KernelThere are many types of kernels that exists, but among them, the two most popular kernels are: 1. MonolithicA monolithic kernel is a single code or block of the program. It provides all the required services offered by the operating system. It is a simplistic design which creates a distinct communication layer between the hardware and software. 2. MicrokernelsMicrokernel manages all system resources. In this type of kernel, services are implemented in different address space. The user services are stored in user address space, and kernel services are stored under kernel address space. So, it helps to reduce the size of both the kernel and operating system.

Summary
What allows the user to communicate with the computer?What is an operating system? An operating system is the most important software that runs on a computer. It manages the computer's memory and processes, as well as all of its software and hardware. It also allows you to communicate with the computer without knowing how to speak the computer's language.
What of the operating system enables users to communicate with the computer system?An operating system uses a graphic user interface (GUI), a combination of graphics and text, that allows you to interact with the computer or device. Every computer or smart device needs at least one operating system to run applications and perform tasks.
How does the operating system communicate with the user?The application programs make use of the operating system by making requests for services through a defined application program interface (API). In addition, users can interact directly with the operating system through a user interface, such as a command-line interface (CLI) or a graphical UI (GUI).
When a computer communicates with the user this is called?Computer-mediated communication (CMC) is defined as any human communication that occurs through the use of two or more electronic devices.
