This is different from proprietary software like Windows, which can only be modified by the company that owns it. The advantages of Linux are that it is free , and there are many different distributions —or versions—you can choose from. However, most servers run Linux because it's relatively easy to customize.
To learn more about different distributions of Linux, visit the Ubuntu , Linux Mint , and Fedora websites, or refer to our Linux Resources. The operating systems we've been talking about so far were designed to run on desktop and laptop computers. Mobile devices such as phones , tablet computers , and MP3 players are different from desktop and laptop computers, so they run operating systems that are designed specifically for mobile devices.
In the screenshot below, you can see iOS running on an iPad. Operating systems for mobile devices generally aren't as fully featured as those made for desktop and laptop computers, and they aren't able to run all of the same software. However, you can still do a lot of things with them, like watch movies, browse the Web, manage your calendar, and play games.

Next: Understanding Applications. A real time operating system time interval to process and respond to inputs is very small. Distributed systems use many processors located in different machines to provide very fast computation to its users.
Network Operating System runs on a server. It provides the capability to serve to manage data, user, groups, security, application, and other networking functions.
Mobile operating systems are those OS which is especially that are designed to power smartphones, tablets, and wearables devices. 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. A 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. Microkernel 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.

This resource will explain how operating systems work, and note the differences between the Microsoft Windows, Mac and Linux operating systems.
An operating system is a program that acts as an interface between the computer user and computer hardware, and controls the execution of programs. The operating system OS manages all of the software and hardware on the computer. It performs basic tasks such as file, memory and process management, handling input and output, and controlling peripheral devices such as disk drives and printers.
The operating system coordinates all of this to make sure each program gets what it needs. The Operating system interfaces with the Hardware.
Each of these interfaces are two way transactions with each sending and receiving data. Operating systems usually come pre-loaded on any computer you buy. Most individuals use the operating system that already comes with their computer however it is possible to upgrade or change the initial operating system to suit your preference.
Different operating systems will work in different ways. They may appear visually different, have different terms for common functions and organise programs in different ways. In the table below, we will outline a few of the key differences between each system. Windows icon.
