Types of Operating System

Within the broad family of operating systems, there are generally four types, categorized based on the types of computers they control and the sort of applications they support.
The broad categories are:
• Real-time operating system (RTOS)
Real-Time Operating Systems are used to control machinery, scientific instruments and industrial systems. An RTOS typically has very little user-interface capability, and no end-user utilities, since the system will be a "sealed box" when delivered for use. A very important part of an RTOS is managing the resources of the computer so that a particular operation executes in precisely the same amount of time every time it occurs. In a complex machine, having a part move more quickly just because system resources are available may be just as catastrophic as having it not move at all because the system is busy.
• Single-user, single task
As the name implies, this operating system is designed to manage the computer so that one user can effectively do one thing at a time. The Palm OS for Palm handheld computers is a good example of a modern single-user, single-task operating system.
• Single-user, multi-tasking
This is the type of operating system most people use on their desktop and laptop computers today. Microsoft's Windows and Apple's MacOS platforms are both examples of operating systems that will let a single user have several programs in operation at the same time. For example, it's entirely possible for a Windows user to be writing a note in a word processor while downloading a file from the Internet while printing the text of an e-mail message.
• Multi-user
A multi-user operating system allows many different users to take advantage of the computer's resources simultaneously. The operating system must make sure that the requirements of the various users are balanced, and that each of the programs they are using has sufficient and separate resources so that a problem with one user doesn't affect the entire community of users. Unix, VMS and mainframe operating systems, such as MVS, are examples of multi-user operating systems.
Mandriva Linux
It's important to differentiate here between multi-user operating systems and single-user operating systems that support networking. Windows 2000 and Novell Netware can each support hundreds or thousands of networked users, but the operating systems themselves aren't true multi-user operating systems. The system administrator is the only "user" for Windows 2000 or Netware. The network support and all of the remote user logins the network enables are, in the overall plan of the operating system, a program being run by the administrative user.
With the different types of operating systems in mind, now we will look at the basic functions provided by an operating system.

Booting! What is this?

Booting! What is this? What is Booting? Booting  (booting up) is a bootstrapping process that starts operating systems when the user turns on a computer system. A boot sequence is the set of operations the computer performs when it is switched on that loads an operating system.   When you turn on the power to a computer, the first program that runs is usually a set of instructions kept in the computer's read-only memory ( ROM ). This code examines the system hardware to make sure everything is functioning properly. This power-on self test ( POST ) checks the  CPU , memory, and basic input-output systems ( BIOS ) for errors and stores the result in a special memory location. Once the  POST  has successfully completed, the software loaded in  ROM  (sometimes called the  BIOS  or firmware) will begin to activate the computer's disk drives. In most modern computers, when the computer activates the hard disk drive, it finds the first piec...
