Operating Systems
(OS)
The principal piece of system software in any computer
system.
Consists of the master programs (supervisor) that manage
the basic operations of the computer
Allows you to concentrate on your own tasks or
applications rather than on the complexities of managing
the computer
It interprets the commands you give to run programs and
allows you to interact with the programs while they are
running
It is automatically loaded into the main
memory as soon as you “boot” your
computer
Platform
The type of computer
architecture, or family.
For the most part,
software created for
one type of platform
will not run, without
special arrangements,
on other platforms.
E.g. IBM, Macintosh.
iMac G5
1.8GHz
Sony VAIO
All-In-One
Desktop with
Intel®
Pentium® 4
Processor
2.8GHz
PC
Command-driven vs. Menudriven Interface
User interface:
Controls the manner of interaction
between the user and the operating
system
Command-driven interface
The user must type in strings of
characters to issue commands. The
mouse may NOT be used
Menu-driven interface
The user is provided with menus
(on-screen lists of options to choose
from) that are used to issue
commands
Multitasking
The execution of two
or more programs by
one user concurrently
on the same
computer with one
central processor
GUI
Stands for graphical user
interface
Uses pictorial figures called
icons to represent tasks,
functions, and programs
Uses windows
They divide the display
screen into sections. Each
window may show a different
display.
Permits the liberal use of both
the keyboard and the mouse
Icons
Tasks
Window
OLE
Stands for Object
Linking and
Embedding
Developed by MS to
support documents
that contain or
reference other
documents
Now a basic
component of Win
95/98/2000/ME/XP/NT
An Excel Spreadsheet
double clicked within
Word
OLE Cont’d
Allows one application to access the
services and data of another. For
example, an object such as a video clip
can be embedded into a text document,
which is then called the client
application or OLE container
When the object is double clicked, the
application that created it, called the
OLE server, is launched so that you can
edit or play the object
DOS
Stands for Disk Operating
System
The oldest commonly
used microcomputer
operating system
Runs on IBM (PC DOS)
and compatible
microcomputers (Compaq,
AST, Dell, Gateway, etc.)
MS DOS is created by
Microsoft (hence the MS)
Command-driven, singleuser program
OS/2
Stands for Operating System 2
Designed to run on IBM and compatible machines
Does not need DOS to run underneath it and has a GUI called
the workplace shell (WPS) which uses icons resembling
documents, folders, printers, etc.
Can run on most DOS, Windows, and OS/2 applications
programs simultaneously.
Don’t need to get rid of old applications
First OS to take full advantage of
the power of the Intel Pentium
microprocessors
Designed to connect small
hand-held personal computers to
large mainframes
Windows 3.x
An operating environment that lays a GUI shell around
the DOS operating system and extends DOS’s
capabilities
Windows lets you display your work in windows
(rectangular portion
of the video display
area with a title on
top) on a desktop.
It supports
multitasking
Windows 3.1 Desktop
Windows 95/98/ME/XP
Major upgrade
designed to replace
Win 3.X
True multitasking
operating system, not
requiring the separate
DOS program
GUI is integrated into
the OS It uses windows
and a desktop
Used for midnetworking/Peer-topeer.
Windows XP Desktop
Windows NT/2000
Multitasking and
multiprocessing
system with an
integrated GUI.
Intended to
support large
networks (multiuser system)
OS/390
The IBM operating system for mainframe and large server
computers
It is used by more computers than any other OS in the world
Payroll, accounts receivable, transaction processing, database
management,
and other programs
critical to the world's
largest businesses are
usually run on this OS
It also comes with UNIX
user and programming
interfaces built in
It can be used as both a
mainframe and a UNIX
system at the same time
Netware
A network needs network
operating system software
(NOS) to provide it with multiuser, multitasking capabilities
facilitates communications,
resource sharing, and security,
thereby providing the basic
framework of the LAN
Consists of modules that are
distributed throughout the LAN
environment
Macintosh Operating System
New MacOS
(Mac OS)
Easy to use interface because hardware
and software were designed together
Set the
standard for
icon-orientated
GUI and
plug-and-play
peripheral
hook ups
Mac Desktop
Unix
Oldest “portable” operating system
Multi-user, multi-tasking operating system with built-in networking
capability and
versions that can run
on all kinds of
computers
Primary users are
government agencies,
universities, large
corporations, and
banks
Linux
A UNIX-like operating system
designed to provide personal computer users a free or very low-cost
operating system comparable to traditional and usually more expensive
UNIX systems. It has a reputation as a very efficient and fast-performing
system
remarkably complete operating system, including a graphical user
interface, and other
components usually
found in a
comprehensive UNIX
system
comes in versions for
all the major
microprocessor
platforms
