This page will help you underestand what different types of operating systems are used and what they look like on screen

Introduction

There are many different types of operating systems used in the modern world. An operating system is the main software that controls the management of activities and the sharing of limited resources of the computer. The operating system is used as a host for applications that are used on the computer.

in other words, oporating systems help to to act as an interface between the user and the computer hardware. an operating system is a set of programs that allows the user to perform tasks without the user knowing they are done…to be continued…

Examples of Operating Systems

once you realise the different types of operating system, you will realise what all that ICT jargon above means.

  • Microsoft Windows
  • Mac OC
  • Linux
  • Solaris

Operating systems offer a number of services to application programs and users. Applications can then process these services through application programming interfaces, or abreviated as APIs or system calls. By making these processes, the application can request a service from the operating system. people will interact with the operating system with some kind of software user interface, or abreviated as UI, typing commands by using command line interface (CLI) or using a graphical user interface (GUI, commonly pronounced “gooey”). Hand-held and desktop computers usually are refered to bieng part of the operating system. On large multi-user systems like Unix and Unix-like systems, the user interface is generally implemented as an application program that runs outside the operating system. (Whether the user interface should be included as part of the operating system is a point of contention.)

Microsoft Windows

Microsoft Windows is an of software operating system and graphical user interface produced by Microsoft. Microsoft first introduced an operating environment named Windows in November 1985 as an add-on to MS-DOS in response to the growing interest in graphical user interfaces (GUIs). Microsoft Windows came to dominate the world's personal computer market, overtaking Mac OS, which had been introduced previously. At the 2004 IDC Directions conference, it was stated that Windows had approximately 90% of the client operating system market. The most recent client version of Windows is Windows Vista; the most recent server version is Windows Server 2008.

Mac OS

Mac OS is the name for a series of graphical user interface-based operating systems created by Apple Inc. (formerly Apple Computer, Inc). The Macintosh user experience, is credited with popularizing the graphical user interface. The original form of what Apple would later name the Mac OS was the integral and unnamed system software first introduced in 1984 with the original Macintosh, usually referred to simply as the System software.

Linux

Linux is a generic term referring to Unix-like computer operating systems based on the Linux kernel. Their development is one of the most prominent examples of free and open source software collaboration; typically all the underlying source code can be used, freely modified, and redistributed by anyone under the terms of the GNU GPL license.

Linux distributions are predominantly known for their use in servers, although they are installed on a wide variety of computer hardware, ranging from embedded devices and mobile phones to supercomputers, and their popularity as a desktop/laptop operating system has been growing lately due to the rise of netbooks and the Ubuntu distribution of the operating system.

The name Linux comes from the Linux kernel, originally written in 1991 by Linus Torvalds. The system's utilities and libraries usually come from the GNU operating system, announced in 1983 by Richard Stallman. The GNU contribution is the basis for the alternative name.
