How is the binary number system different from ours?

In short, binary is a base-two system, while ours is base-ten. If that's not enough information for you, read on.

In our number system, the natural number sequence goes like this:

1, 2, 3, 4, 5, 6, 7, 8, 9, 10, etc.

In binary, the same sequence goes like this:

1, 10, 11, 100, 101, 110, 111, 1000, 1001, 1010, etc.

Therefore, 1 in binary is 1, 2 is 10, 3 is 11, 4 is 100, and so on. (Note that these should not be pronounced as "ten", "eleven", or "one hundred", but instead as "one zero", "one one", and "one zero zero".)

Binary works in powers of two. Take a look at the following number, which is 19 in binary:

10011

Each digit, starting from the right, represents 1, 2, 4, 8, and 16. These are equal to 20, 21, 22, 23, and 24. This might make a little more sense (maybe?):

1 0 0 1 1

↑ ↑ ↑ ↑ ↑

16 8 4 2 1

Now you can see that what each digit represents more clearly. The 1 on the left represents 16, the second 1 represents 2, and the 1 on the right represents 1. We don't need to worry about the 0's; they are just placeholders. If you add up what each 1 represents (16, 2, and 1), you get 19. This is why 10011 is 19 in binary. The same rules apply to reading and writing other binary numbers.

"There are 10 types of people in the world: those who understand binary and those who don't."

Why would the battery on your HP laptop drain when turned off?

All batteries will drain a small amount, even if they are not being used. However, a substantial battery drain would be due to a problem with the battery or laptop.

Make sure that the laptop is indeed off, though. With Vista, clicking the power button in the start menu will not shut down the laptop, but will instead put it into sleep mode. This continues to drain the battery. Some of the lights on the computer will still be lit when the laptop is in sleep mode, while no lights will be on if the laptop is turned off.

Is it safe to open a port on your router?

Yes and no. It depends on the reasons for opening a port.

Yes - You can open ports on your router if you have specific software that run on your computer that need that port opened. Some programs like UTorrent, games, or home made servers require some ports opened. While these programs are generally safe to have opened ports associated with them, anything is possible when it comes to attacks. Usually, software companies will try update their programs to make it more secure with the knowledge that you have an open port on your computer. Also, that open port is only going to be used by the specified software that needs it.

No - You don't want to open a lot of ports, it gives a person more chances to get onto your computer. It weakens the security of your computer and increases your chance of an attack. But if done correct, you can open ports that will be used by specific programs and be generally safe.

Think of it as unlocking and locking doors in your house. The more doors you unlocked, the higher a chance someone will try a door and it will just let him/her in. On the other hand, if you have a door that you use very frequently throughout the day, you might leave it unlocked.

What is a good gaming computer for less than 400 Without intel graphics and prefferably dual core processor?

You will not likely find a good gaming computer for only 400. I paid 500 for my laptop, and there is some games it cannot handle, such as dues ex. If your budget is 400, I'd suggest a desktop. They have better parts than a laptop which would make them better able to handle todays advanced games. At only 40, there will still be limits but a desktops parts are more easy to replace than a laptops, so you can slowly buy upgrade parts to replace cheaper ones. eventually, you will have a thousand dollar computer that you probably only invested 800 in.
