Applications cannot run on their own

Rely on operating system software Operating system provides

the interface between the

WHAT IS AN OPERATING SYSTEM?

An interf ace between user s and hardware - an environment "ar chitecture´

Allows convenient usage; hides the tedious stuff

Allows eff icient usage; par allel activity, avoids wasted cycles

Provides information protection

Gives each user a slice of the resour ces

Acts as a control progr am.



Where the Operating System Lives

6 May 2011

´Modern computers store part of their operating system in ROM forstartup

´

The remaining system(or kernel) is loaded into RAM memory as the system starts (aprocess known as booting)

´ Once up and running, the OSworks mostly behind the scenes,managing computer operations



What the Operating System Does

1. Communicates with peripheralsSending and receiving info to/f rom screens,

printers, hard drives, optical drives, etc.

2. Coordinates concurrent processingMultitasking between applications

8




3. Manages memoryAllocating memory to applications

9




4. Monitors resources and provides securityPrivacy and security of user data

5. Manages programs and dataFile system management

6. Coordinates network communicationsCommunication between computers

Linux

� Linux was created by Linus Torvalds

� Free for anyone to use or improve(i.e. open source sof tware)

� Free, reliable alternative to Unix, Windows. Runs on many Platforms.Open-source.

� LINUX is a f ree version of UNIX that runs on Intel/Cyrix/AMDPentium, Intel 80x86, Motorola/IBM PowerPC, Motorola 680x0, SunSPARC, SGI MIPS, DEC Alpha, HP PA-RISC, DEC VAX, ARM, API 1000+,and CL-PS7110.

Windows Vista Windows XP

Easier to install in comparison Hardware and Software support

range is less

Has a quick start-up

Much more secure More synchronized explorer (AERO

user- interface)

Greater support for wi-fi

connectivity and gaming

Much more lengthier task Supports much more wider range

Not as quick

Less secure Explorer not as user-friendly

Less support

Why Did Windows Vista Fail?

Over Promised Under Delivered Bad Marketing

Too Many Ver sion Rushed To Market

Over pr iced Competition from Apple

Slow ± 50,000,000 lines of code Required more powerf ul hardware

Dr iver problems Expensive vendor certif ication

User Access Control (

U AC)

Upgr ades from 98 and XP f ailed

³Bootleg´ XP Readily Available Designed by committee

Cor por ate IT Wasn¶t Ready Over -reacted to secur ity issues

What·s Improved In Windows 7?

Looks Pretty Runs Faster

Requires less hardware resour ces Smaller footpr int

Loads and shuts down much f aster Improved sear ch capabilities

New task bar Easier f ile shar ing

Beautif ul wallpaper Multi-touch capability

Virtual folder s Easier to view r unning progr ams

Non-essential progr ams eliminated Still too many ver sions



Selecting the Right O.S.

� Addresses our C urrent Needs

� Inter-Operability � Support for Different Hardware Platforms

� Maintainability

� Non-Propriety

� POSIX- C ompatibility
