Слайд 2An operating system (OS) is the program that, after being

initially loaded into the computer by a boot program, manages all the

other programs in a computer. The other programs are called applications or application programs.
In addition, users can interact directly with the operating system through a user interface such as a command line or a graphical user interface (GUI).

Слайд 3Real-time operating system
Real-time operating system - A real-time operating system is

one in which processing requests made by the user are

executed immediately. It manages the computer resources and handles the operation in a precise way by providing equal amount of time for every operation. It has very little user-interface capability, and no end-user utilities.

Слайд 4Batch processing operating system 
A batch processing operating system is one

where processing requests are grouped together in batches to be

run all at once. By grouping processing requests together into batches computers can be used more efficiently by removing the slowest part of the system; the user.

Слайд 5Single-User, Single Task Operating System Single-User, Multi-Task Operating System:
Single-User, Single Task

Operating System:
These operating systems work on single task and single

user at a time.
Example: The Palm OS for Palm handheld computers

Single-User, Multi-Task Operating System:
These operating systems works on more than one task and process them concurrently at a time.
Example: all later versions of Windows

Слайд 6Multiuser Operating System:
In these OS, multiple users are allowed to access

the same data or information at a time via a network.

The users can also interact among each-other. Some examples of this type of Os are: Linux, UNIX, and Windows 7.

Слайд 7Multiprocessing Operating System:
Here, a single process runs on two or

more processors. All the processing and their management takes place

in a parallel way, hence this OS are also called as Parallel Processing.  As their execution works in parallel, these are applicable for high speed execution, and also to increase the power of computer. For example: Linux, UNIX and Windows 7 are examples of multiprocessing OS.

Слайд 8Embedded Operating System:
These are applicable and developed only for the

needed resources and accordingly developed. These OS are less resource

intensive. Mainly, applicable in appliances like microwaves, washing machines, traffic control systems etc

Слайд 9Distributed Operating System: 
In these OS, the computers work in co-operation

with each other. As this OS manages a group of

independent computers and makes them appear to be a single computer is known as a distributed operating system.
