3. Next I will be reviewing the attributes of three popular operating systems
The operating systems I will be reviewing are Mac, Linux, & Windows.

4. Windows Highly compatible Feature – rich
Large selection of software applications
Optimized memory usage to ensure a fast and reliable performance
Quick and easy to navigate
Been redesigned for better power management through:
* reducing background activities
* Less power-hungry media drive
* Auto screen dimming
* Automated removal of power to unnecessary ports
Windows:

5. Pros
More then 80% of the desktop computers in the world run some sort of Windows operating system.
There is a large supply of Windows hardware and drivers.
Most widely supported operating system for games.
Large shareware and freeware application library.
Multiple support options.
Pros:

There is a large supply of Windows hardware and drivers.
Most widely supported operating system for games.
Large shareware and freeware application library.
Multiple support options.

6. Cons
The most prone operating system for spyware and virus applications.
High probability that you will need support.
General instability because of the number of possible configurations.
Poor security.
It can’t be modified for your own use.
Cons:
The most prone operating system for spyware and virus applications.

General instability because of the number of possible configurations.
Poor security.
It can’t be modified for your own use.

7. Mac Used by a range of casual buyers to computer professionals
Continually updated every year with new features
Runs on Macintosh computers only
Has been around since 1984 when the first Macintosh was introduced
Mac OS was completely revamped in 2001
* based on the same kernel as UNIX but has more advanced administrative features and utilities
* still consists of easy to use Apple software that customers expect
Mac:

Continually updated : each release is signified by a new number (Mac OS 8)

8. Pros Minimal technical maintenance needed
Content creation is its strength
More secure than Windows
Tight control over the configuration options
Almost no spyware or virus applications.
More powerful than Windows due to its UNIX base.
You have almost complete access to the enormous library of free open source applications.
Pros:
Minimal technical maintenance needed
Content creation is its strength
More secure than Windows
Tight control over the configuration options
Almost no spyware or virus applications.
More powerful than Windows due to its UNIX base.
You have almost complete access to the enormous library of free open source applications.

9. Cons More expensive upfront compared to the other systems
Not as many support options
Less hardware choices than Windows.
More complex than Windows because its UNIX base.
Cons:
More expensive upfront compared to the other systems- Expensiveness would be offset by the minimal maintenance
Not as many support options – ex: Apple stores for support

10. Linux An operating system that was developed by collaboration
Today Linux is the fastest growing operating system
Contains all the required features of the to date desktop PC’s: firewalls, corporate file servers, routers and internet servers
It’s compatible with all common UNIX software
Linux:
An operating system that was developed by collaboration – which means not one certain company was in control
Today Linux is the fastest growing operating system
Contains all the required features of the to date desktop PC’s: firewalls, corporate file servers, routers and internet servers
It’s compatible with all common UNIX software

11. Pros
Free software
Strong security so you don’t need home security system
You have the ability to change what you want when you want
Designed to do multiple tasks at the same time
Ideal for older computers that have difficulties with other operating systems
Open source software
Pros:
Free software
Strong security so you don’t need home security system
You have the ability to change what you want when you want
Designed to do multiple tasks at the same time
Ideal for older computers that have difficulties with other operating systems
Open source software
Ideal for older computers – because its much faster

12. Cons You will have a hard time getting help with computer issues
The user interface isn't as innovative and complex
Most computer games aren't supported
Operating system can be uncertain and problematic
Need prior programming information for any problems
Cons:
You will have a hard time getting help with computer issues
– because there aren't a lot of knowledgeable people that are willing to help fix problems
The user interface isn't as innovative and complex
Most computer games aren't supported
Operating system can be uncertain and problematic
Need prior programming information for any problems
Temperamental – random crashes
