Classification of Operating System

 Classification of operating systems

The operating systems may be classified into different types depending upon the nature of interaction between the user and his/her program. The various types of operating system are :

1.     single user operating system  

2.      Multi user operating system 

3.       Batch processing operating system

4.      Multi programming operating system 

5.     Multi tasking operating system 

6.       Multiprocessing operating system

7.       Time sharing operating system

8.     Real time system  

 Distributed system

Multi threading operating system



 

 

 

Single user operating system

·                     In single user operating system, a single user can access the computer at a particular time.

·                     The computer, that are based on the operating system have only single processor and execute only a single program at all the time

 

·                     Single user is of two type :

1.       single user, single-tasking operating system.

2.       Single user, multi-tasking operating system

 

·         Single user, single tasking operating system: the single user, single tasking operating system allows a single user to execute one program at a particular time. for example MS-dos and palm OS for palm handheld computer are single user single tasking OS

 

·         Single user, multi tasking operating system: the single user, multitasking operating system allows a single user to execute multi programs at a same time. For example, a user can perform different tasks such as making calculation in excel sheet, printing a word document and download a file from the internet at the same time .

Monolithic Architecture

  Monolithic Architecture Monolith means composed all in one piece. The  Monolithic  application describes a single-tiered  software  application in which different components combined into a single program from a single platform. Components can be: Authorization — responsible for authorizing a user Presentation — responsible for handling HTTP requests and responding with either HTML or JSON/XML (for web services APIs). Business logic — the application’s business logic. Database layer — data access objects responsible for accessing the database. Application integration — integration with other services (e.g. via messaging or REST API). Or integration with any other Data sources. Notification module — responsible for sending email notifications whenever needed. Example for Monolithic Approach Consider an example of Ecommerce application, that authorizes customer, takes an order, check products inventory, authorize payment and ships ordered products. This applicat...

Micro kernel architecture

  Micro kernel  architecture What is Kernel? A kernel is an important part of an OS that manages system resources. It also acts as a bridge between the software and hardware of the computer. It is one of the first program which is loaded on start-up after the bootloader. The Kernel is also responsible for offering secure access to the machine's hardware for various programs. It also decides when and how long a certain application uses specific hardware. What is Microkernel? Microkernel  is a software or code which contains the required minimum amount of functions, data, and features to implement an operating system. It provides a minimal number of mechanisms, which is good enough to run the most basic functions of an operating system. It allows other parts of the operating system to be implemented as it does not impose a lot of policies. Microkernels and their user environments are usually implemented in the C++ or C programming languages with a little bit of assembly. Ho...

Defination of OS(operating system) and its concepts

    What do you mean by operating system?     Definition :  An operating system is a program that act as an interface between the user of a computer and the                                      Computer hardware. Operating system is a first program that gets loaded into the memory through a process called booting. Concepts of operating system : ·                       The purpose of operating system is to provide an environment in which a user can execute program in a convenient and efficient manner. ·                       Operating system is an integrated set of program that ma...

Virtual Machine Architecture

  Virtual Machine Architecture A virtual machine can exist as a standalone machine or it can exist within a vApp. A virtual machine is a software computer that, like a physical computer, runs an operating system and applications. The virtual machine consists of a set of specification and configuration files and is backed by the physical resources of a host. Every virtual machine has virtual devices that provide the same functionality as physical hardware are more portable, more secure, and easier to manage. Virtual machines can be standalone, or they can exist within a vApp. A vApp is compound object composed of one or more virtual machines as well as one or more networks. 1.    Monolithic architecture 2.     Layerd archtecture . 3.     Virtual machine architecture 4.       Exokernel architecture 5.      Client server architecture   6.       Micro kernel architecture The following figure ...
