Types of Operating System For Computer

An operating system is a set of programs that provide common services for controlling and allocating memory, prioritizing system requests, controlling pointing devices and output devices, facilitating networking, managing file systems. Important types of the operating system are Windows, Linux, Unix, and mac os.

Operating System

An operating system is a set of programs that control and manages all computer resources and operations. The operating system is the most important type of system software that executes user programs and makes an easier solution to user problems. Users also interact with different types of computers through an operating system.

Furthermore, A computer can do nothing without an operating system. An OS must be installed on every computer. when a computer is turned on, the operating system runs a check that all parts of the computer are functioning properly. The operating system manages all operations on a computer after loading.

In addition, an operating system is a set of programs that acts as an interface between a user and computer hardware. Popular types of operating systems are DOS, Windows, Unix, OS/2, Linux, etc.

History Of Operating System

The first OS was the GM-NAA I / O. It was manufactured by General Motors Research for its IBM 704 in 1956. After that, with the invention of personal computers in 1975, the user was using a command-line interface.

A set of commands are used to perform specific functions through the operating system, which was very tough and tedious. Today, every computer is being operated uses a GUI (graphical user interface) that is much easier to work with os.

Components Of Operating System

Any operating system in the world contains 5 basic components that work with each other in reliability and consistency. And it is impossible in the absence of any of them to say that this is an operating system.

Here are these components:

  • The kernel

The kernel is one of the most important components of the Windows operating system. It serves as the bridge between computer hardware and software. It ensures the process of controlling the device’s resources and creates a layer that software can communicate with.

Moreover, it’s responsible for providing computer capabilities for software controlled by the user. In addition, it translates the commands entered to it by the command interpreter transfers them to memory, and organizes spaces and works.

  • Boot Loader

The boot loader is the program entrusted with loading the rest of the parts of the operating system after the success of the POST tests.

The boot loader is usually located on the first boot disk and is called by the BIOS, which then moves it from the disk to the main memory.

  • Libraries

They are a group of subprograms used for software development. They contain data that provides services for stand-alone programs, configuration data, documentation, and help data.

Libraries put references to each other called links in the field of programming and performed by a program called Linker.

  • Hardware Controllers

Also known as the Device Driver or Firmware, it is a computer program that serves as a driver or definition for computer hardware and its accessories.

The driver software often communicates with its device through the computer path or communication system to which the device is connected.

  • Command Interpreter

Which is known in the technical language of PAL Compiler, is a software program that converts source files Source code directly to the commands understood by the computer and executed directly to suit the target computer program structure.

Types of Operating System

Earlier, many operating systems were device-dependent and proprietary.  A type of software that runs only on a specific type of computer is called device-dependent. A type of software that is privately owned and limited to a specific vendor or computer model is called proprietary software.

Another type of operating system that recognizes and works with application software written for an earlier operating system is called downward-compatible.

Manufacturers normally introduced a different operating system for each new computer model and it was a problem for the user to switch from one computer model to another. The application software could not work on different computer models.  Here is the list of important types of the operating system are as follows:

  • Multi-user OS
  • Multiprocessor OS
  • Multitasking OS
  • Multithreading OS
  • Time-Sharing OS
  • Stand-Alone OS
  • Network OS
  • Embedded OS 

Multi-User Operating System

A multi-user operating system allows multiple users to share data and the same computer at the same time. A powerful computer server controls how the computer works and communicates. Some important examples of multi-user operating systems are Linux, UNIX, and Windows 2000.

Multi-Processor Operating System

Multiprocessor operating system is the second most important type of operating system. Multiprocessor operating system supports two or more processors that run programs at the same time.

All the CPUs work with close communication and are sharing their resources like computer buses, peripheral devices, and memory. Examples of multiprocessing operating systems are Linux, UNIX & Windows 2000.

Multitasking Operating System

A multitasking operating system executes more than one program at the same time. This operating system monitors your position inside these tasks and shifts from one task to another without any loss of information. Some examples of multitasking operating systems are UNIX and Windows 2000.

Multithreading Operating System

An operating system that allows different parts of a program to run concurrently is called a multithreading operating system. This operating system allows a user to support multiple threads of execution inside a single process. Examples of multithreading operating systems are Linux, UNIX, and Windows 2000 also.

Time-Sharing Operating System

The time-sharing operating system enables a large number of users to share the computer simultaneously. It is used when many users are linked through communication networks to a single computer.

The computer first works on one user’s task for a fraction of time and then goes to the next computer rapidly. It also switches back and forth among different tasks.

Stand-Alone Operating Systems

An operating system that can be operated on a desktop, notebook computer, or any mobile computing device is called a stand-alone operating system. A stand-alone operating system that combines works with a network operating system is called a client operating system.

Common types of stand-alone operating systems are DOS, Windows 95, Windows NT Workstation, Windows Me, and also Windows XP Home Edition, etc.

DOS

DOS stands for Disk Operating System. This operating system is also called Command Prompt operating system. MS-DOS was developed by Microsoft in the early 1980s for personal computers. It is a type of single-user operating system in which only one user can work at a time.

Windows XP

Windows XP is also a product of Microsoft Corporation. It’s released in 2001. XP stands for experience. It provides a quicker startup, better performance, and a new visual look. Three versions of Windows XP are Windows XP Home Edition, Windows XP Professional, and Windows XP Server.

Mac OS

Macintosh’s operating system is a product of Apple. It was one of the first successful GUI. It was released with Macintosh computers in1984. The latest version of this operating system is called Mac OS X. It is a desktop interface with 3-D visualization. UNIX and old Mac applications are easy runs on Mac OS X.

Network Operating Systems

An operating system that is developed to support personal computers, terminals and workstations connected over a network is called a network operating system. It normally works on a server. Types of the network operating system are:

  • Windows NT Server,
  • Windows 2000 Server
  • NetWare
  • UNIX
  • Linux
  • Solaris

NetWare

Novell’s Netware is a network operating system. It is designed for a client/ server network. In addition, it is also important to know that the server portion of this operating system resides on a network server and the client portion resides on each client computer.

Windows NT Server

Windows NT Server is also a product of Microsoft. It is designed for client/server networks. The server in the network uses the Windows NT Server operating system. The client computers use Windows NT Workstation or other stands alone versions of windows.

UNIX

UNIX is a multitasking operating system. It was developed in the early 1970s at Bell Laboratories.  Many versions of this operating system are available also. It uses a command-line interface. UNIX is mainly used in network environments and is very popular for its security also.

Linux

Linux is a free and multitasking operating system. This operating system was developed in 1991. It is also open-source software. It means that its code is available to the public. Some versions of Linux use a command-line interface and others use GUI. Examples of  Linux are LINUX MINT, Manjaro DEBIAN, UBUNTU, etc.

Solaris

Solaris is a version of the UNIX operating system. It was developed by Sun Microsystems. Solaris is a network operating system also designed for e-commerce applications. In addition, it can manage high traffic accounts and security for web transactions. The client version of Solaris is also called CDE.

Embedded Operating Systems

An operating system that is used in most handheld computers and small devices is called an embedded operating system. It resides on a ROM chip. Some types of embedded operating systems are:

  • Windows CE
  • Pocket PC 2002
  • Palm OS
