 An Operating   System
Definition
An operating system is an integrated set of
 programs that controls the resources (cpu, memory,
 input/output devices etc. ) of a computer system and
 provides its users with an interface.




              1                                         2
The OS is the computers master control
 program. The Os provides us with commands that
 enables us to interact with the pc. When we issue
 a command, the OS translate it into code that the
 machine can use.
 Some popular operating system are-
   Unix, Ms-Dos, Microsoft Windows, Microsoft
   Windows NT, Linux.
Functions of the operating
System
 1. It displays the on-screen elements
  which we interact.
 2. It loads programs into the computers memory
  so that we can use them.
 3. It coordinates how programs work with the
  computers hardware and other software.
 4. OS manages the way how information is stored
  on and retrieved from disk.
Types of operating system;
1. Real time operating system,
2. Single user  Single tasking OS,
3. Single user  MultitaskingOS,
4. Multi user  Multitasking OS.
Real time operating system
A real time operating system is a very fast, relatively
   small OS.
It is needed to run real-time applications.
It may support multiple simultaneous tasks or it may
   support only single tasking.
Real time applications are needed to run medical
   diagnostics equipment, life-support system, scientific
   instruments & industrial system.
Single user/single tasking operating
system
An operating system that allows a single user to perform
  just one task at a time is a Single user-single tasking
  operating system.
To a user a task is a function such as printing a document
  , writing a file to disk, editing a file or downloading a
  file from a network server.
MS-DOS is an example of a single-tasking OS
Single user/multitasking Operating
system
A single user-multitasking operating system is one that
  allows a single user to perform two or more functions
  at once.
The most commonly used personal computers usually
  run such Oss, including Microsoft Windows and
  Macintosh operating system.
Multi user/ Multi tasking Operating
system
A multi user-multi tasking operating system is an
  operating system that allows multiple users to use
  programs that are simultaneously running on a single
  network server called terminal server.
In a multi user-multi tasking operating system
  environment all or most of the computing occurs at
  the server.
Examples of multi user- multi tasking Oss include
  UNIX, VMS
User Interface
When we work on a computer we see and use a set of
  items on the screen
Taken together, these items are called the user interface.
The two most common types of user interface are:
 Graphical user interface and
 Command line user interfaces.
