The document discusses the history and components of operating systems (OS). It describes how the first OS was created by General Motors in 1956 for IBM mainframe computers. In the 1960s, IBM developed OSes to distribute with their computers. The document defines an OS as software that manages computer hardware resources and allows users to run application programs. Key OS functions include starting and shutting down computers, providing user interfaces, coordinating tasks, managing memory and devices, establishing network connections, and more. Common OS types include normal, real-time, network, standalone, server, and embedded OSes. Major OS components are process management, memory management, file systems, device drivers, networking, security, and I/O devices.

3.  The first operating system was created by
the General Motor’s in 1956 to run single IBM
mainframe computer
 In 1960s IBM was the first computer manufacturer
to take on the task of operating system development
and distributing operating system with their computer.
 On August 28,1980,Microsoft signed a agreement with
IBM to develop software for PC, Gates was aware of an
operating system called “QDOS”, which had been develop
by fellow.
 A real inventor “UW’s Gary Kildall”,father of PC operating
system honoured for key work growing up in California.

4. Definition:
• An operating system (OS) is a “The operating system act as
collection of software that interference between the user
manages computer hardware and computer hardware”
resources.
• Without a computer operating
system. a computer would be
useless.
Application software
Operating system software
Hardware system

5. Start and shutdown
a computer
Provide a user interface Manage program
Coordinate tasks Configure devices Manage memory
Establish an internet
connection
Control a network Provide utilities

6. • User interact with operating system
• Core of operating system, responsible for loading
operating system
User interface

GUI Multiuser Multitasking Multiprocessing Multithreading

8.  Normal Operating system
 Real time Operating system
 Network Operating system
 Stand alone Operating system
 Server Operating system
 Embedded Operating system
 Microsoft Window
 iPhone Operating system(IOS)
 Linux Operating system
 Unix Operating system

9.  Process management
 Interrupt
 Memory management
 File system
 Device driver
 Networking
 Security
 I/O device

10. • As operating system controls and
coordinates the use of hardware
among the various application
program for various uses, we can
say that it plays a very important rule
for computer system.
