Binary numbers, as with decimal, octal, and hexadecimal numbers, are organized into columns. To learn binary math, we first need to understand how number systems operate. Let's take a look at the decimal system first, since it is simple and easier to think about. We can consider the number "1234" as,

Thousands	Hundreds	Tens	Ones
1	2	3	4

Which means,
1234 = 1x1000 + 2x100 + 3x10 + 4x1

Given,

1000 = 10^3 = 10x10x10
100 = 10^2 = 10x10
10 = 10^1 = 10
1 = 10^0 (any number to the exponent zero is one, except for zero)

The table above can be represented as,

Thousands	Hundreds	Tens	Ones
10^3	10^2	10^1	10^0
1	2	3	4

such that,

1234 = 1x1000 + 2x100 + 3x10 + 4x1 = 1x10^3 + 2x10^2 + 3x10^1 + 4x10^0

The decimal system, as with decimal math, operates in "base 10" (dec being the Latin prefix for ten) using the digits 0-9 to represent numbers, whereas the binary system, as well as its math, operates in "base 2" (bi being the Latin prefix for two) using the digits 0-1 to represent numbers. The base is also known as the radix. In other words, the table above can be represented as,

	Thousands	Hundreds	Tens	Ones
Decimal	10^3	10^2	10^1	10^0
Binary	2^3	2^2	2^1	2^0

In base 10, we put the digits 0-9 in columns 10^0, 10^1, 10^2, and so on. To put a number that is greater than 9 into 10^n, we must add to 10^(n+1). For example, adding 10 to column 10^0 requires us to add 1 to the column 10^1.

In base 2, we put the digits 0-1 in columns 2^0, 2^1, 2^3, and so on. To put a number that is greater than 1 into 2^n, we must add to 2^(n+1). For example, adding 3 to column 2^0 requires us to add 1 to the column 2^1.

Here are some decimal numbers represented in binary.

Decimal	Binary
1	1
2	10
3	11
4	100
5	101
6	110
7	111
8	1000
9	1001
10	1010

Google Document location: Upper left corner

The Documents link as seen below.

Clicking the Documents link opens a page as seen below.

This is where we can share our document to our friend. If you want to see the complete how to use this aplication, you can visit http://www.google.com/google-d-s/intl/en/tour1.html
There is you can find a tutorial about Google Docs.

Office 2010 will be slightly different from previous versions. On this latest edition, Microsoft will develop the most pupular software in the world with web-based operation. Where users can create and edit documents in a web browser. So that Office 2010 can be synchronized with the Internet online. This main function will differentiate this product with Office 2007.
This seems intended to compete Googgle, since a year ago has spread documents operation programme online and free, through the features of Google.doc, Office 2010 product will be marketed to corporate and individual. The online version will also be provided so that we can buy the software by downloading it.

Comfortable fit for right or left hand. This info can be obtained at http://usb.brando.com.hk/. The price is not too expensive at around $ 12.
Some time ago I tried to find in stores around where I live, but has not been found. Maybe in other cities already have or may be we can not find yet in Indonesia?

1. The inclusion of Flash Lite, which should open up a whole new world of web pages to the mobile community.
2. Include Google Gears, which will offer access to Google applications like Gmail and Google Docs when offline.
3. Adds support for silky-smooth OpenGL ES hardware accelerated graphics. This should help make the browser's animations more fluid (this requires 3D hardware and drivers, available on many smart phones, including HTC models).
4. The new version also uses server-side compression to offer ultra-fast page load times. In a speed test, the new browser loaded a website in 9 seconds that took Microsoft's Internet Explorer mobile over 3 minutes.

It is worth noting that most of these features are available in the beta of Skyfire, a new independent browser entry for Windows Mobile smart phones. However, Opera Mobile 9.7 one ups Skyfire as well, offering WXGA and VGA support. Opera Mobile is also available on a couple of mobile OS's besides Windows Mobile. It's also supported on S60 and UIQ operating systems.

Sadly, neither entry is available for the popular iPhone, due to Apple's restrictions on third-party browsers. However, the good news is that these new entries place the onus on Apple and other smartphone makers to make more full-functioned browsers or risk losing business.

Opera Mobile 9.7 is currently being tested and will be released to the public in a few short months.

Because the capacity of RAM is exhausted, RAM (Random Access Memory) commonly used to store data in computers. This means the data can only be viewed on screen, but we have not saved to storage media, such as Hardisk, flash, CD Room, and so forth. The more applications that we open in our computer, the more likely that we use the RAM. As an illustration of RAM as follows. Eg in the computer we installed RAM with a capacity of 512 Mb. Each application will be open that we need RAM, or easily open each individual application we then have a supply of RAM will be reduced. For instance, for example, if we open a Microsoft Word, Microsoft Word will then need temporary memory (RAM) of 300 Mb (not the actual data, because I had not need Microsoft Word to measure how much memory to be able to walk), the supply of RAM that is live ( 512-300 = 212 Mb). If we reopen the application can not be more than 212 Mb, if the application dibukan exceeds 212 Mb, eg Microsoft Excel memory required is 300 MB, the computer will Hang (OVER CLOCK), because the memory requirement for running the program is not enough. To increase the capacity of RAM is usually we need to purchase additional RAM, to be larger. However, the material in this time we will increase the capacity of RAM with FLASHDISK, with the argument, that can work double-flash can be used for RAM can also save data. The greater capacity of flash, then the larger the RAM, which you can add.
