Top 10 differences between Mac and Windows
It is common to all to think of what are the differences between Mac OS from Apple and Windows versions from Microsoft.When I did a timed search for this I found that the following are the top 10 main notable differences between Mac and Windows.There are many word ways to say these simple 10 in 100lines but I am the one to look the things at glance to save time I write them in simple straight way.But it is the main factor that you understood any five differences between these two to pour into your knowledge ocean .
MAC OS from apple when compared with windows from Microsoft
1) Mac provides security from viruses etc.,(Mac is UNIX based ).But not completely virus protected , it had own some viruses :) .
2)Best suitable for multimedia based applications like photoshop,movie editing etc.,
3)Easy user friendlyness('childlike') within 3 days you will be familiar with Mac If you are new to it.
4)Never allows executable programs to be send as a mail attachments.As outlookexpress from microsoft allows executable programs to be attached to mails and which is the main cause for spreding of viruses.
5)Some what cheap but if you need more functionality you need to buy OSX.
6)You can't listen or able to play music etc., except from Apple site ,thats why it is secure in one
aspect but your world is limited .
7)Administrator is root in Mac but if he is doing some thing regarding security concerns then it
will ask root password. Where as in windows it is administrator who is the final god.
i.e, Mac maintains 2 levels of administrator previlages.
8)To download something in windows operating system from internet it is the browser which ask and controls your downloads by asking your permissions,where as in Mac it is under the complete control of Mac OS by concerning to the permissions for that user(more restricted to do download suspious things).
9)In Mac you can create many common users as like Windows.
10)We can't assure that Mac doesnot affected by viruses as some companies already released some anti-virus software for MAc.Only numorous viruses are found for Mac.
Finally in one word "Mac provides user friendly(like windows),Security(like UNix like systems)
providing operating system you can use it as best for multimedia applications,photoshop creations BUT your entertainment world,download world is limited and some countable viruses are there for Mac".
What is Mac OS X ??

Viruses, worms and Trojan Horses
Viruses, worms and Trojan Horses are all malicious programs that can cause damage to your computer, but there are differences among the three.
Here is the definations of Viruses, worms and Trojan Horses provided for you.
A computer virus:- it is attached to a program, or file so that it is spread from one PC to another computer.
Almost all viruses are attached to an executable file, which means the virus may exist on your computer but it cannot infect your computer unless you run or open the malicious program.
i.e. A virus cannot be spread without a human action, (such as running an infected program).
It is spread generally by sharing infecting files or sending e-mails.
worm :- similar to a virus but it has the capability to travel without any help from a person.
a worm can send a copy of itself to everyone listed in your e-mail address book without your action .
worm consumes too much system memory (or network bandwidth), causing Web servers, network servers and individual computers to stop responding.
Trojan Horse :- it will appear to be useful and legitimate software or legitimate files but will actually do damage once you installed or run on your computer.
They can cause changing your desktop( like adding silly active desktop icons) , deleting files and destroying information on your system.gives malicious users access to your system( called as BACKDOOR)
Note:-Unlike viruses and worms, Trojans do not reproduce by infecting other files.
Note:-A "blended threat" is a sophisticated attack that bundles some of the worst aspects of viruses, worms, Trojan horses and malicious code into one threat.

Booting
BOOTING:-
1."Everything that happens between the time the computer is switched on and it is ready to accept commands/input from the user is known as booting."
2.Booting is the process of loading an operating system into computer primary memory (RAM).
Note:-The term booting originated from bootstrap.
TRIVIA:-
WARM BOOTING:- "you can perform a warm boot by pressing the Restart button".
Restarting a computer that is already turned on via the operating system.
Restarting it returns the computer to its initial state.
Also called rebooting , soft reset.
A warm boot is sometimes necessary when a program encounters an error from which it cannot recover. On PCs, you can perform a warm boot by pressing the Control, Alt, and Delete keys simultaneously.
COLD BOOTING:-The start-up of a computer from a powered-down, or off, state. Also called a hard boot.
i.e. Natural way of starting a computer.
