Binary Numbers: Decimal Conversion

How to convert from a decimal-to-binary and binary-to-decimal? The answer of this question is shown below. I hope this can help you.

Decimal to Binary
To Convert a decimal number to a binary number follows a straightforward method.
It involves dividing the number to be converted, say N, by 2 (since binary is in base 2), and making note of the remainder. We continue dividing the quotient (N / 2) by 2, until we reach the division of (1 / 2), also making note of all remainders.
Example 1: Convert 98 from decimal to binary.


1) Divide 98 by 2, making note of the remainder. Continue dividing quotients by 2, making note of the remainders. Also note the star (*) beside the last remainder.
DivisionRemainder,R

98 / 2 = 49

0

49 / 2 = 24

1

24 / 2 = 12

0

12 / 2 = 6

0

6 / 2 = 3

0

3 / 2 = 1

1

1 / 2 = 0

1*



2) The sequence of remainders going up gives the answer. Starting from 1*, we have 1100010. Therefore, 98 in decimal is 1100010 in binary.

Example 2: Convert 21 into binary.

DivisionRemainder,R

21 / 2 = 10

1

10 / 2 = 5

0

5 / 2 = 2

1

2 / 2 = 1

0

1 / 2 = 0

1*



Therefore, 21 in decimal is 10101 in binary

Binary to Decimal

Now, how to convert from binary to decimal number. Binary to decimal conversion follows the same steps as decimal to binary, except in reverse order. We begin by multiplying 0 x 2 and adding 1. We continue to multiply the numbers in the "results" column by 2, and adding the digits from left to right in our binary number.

Example 1: Convert 11101 from binary to decimal.

OperationResult

0 x 2 + 1

1

1 x 2 + 1

3

3 x 2 + 1

7

7 x 2 + 0

14

14 x 2 + 1

29



Therefore, 11101 in binary is 29 in decimal.

Bluetoth 3.0 Had Been Released

Bluetoth 3.0We generally hear and maybe always use bluetoth. When I read a PC magazine I find a good news about bluetoth. Bluetoth Special Interest Group have launch Bluetoth 3.0 and it specification. Bluetoth 3.0 is a high speed wireless connection. The highest speed of bluetoth 3.0 can reach until 24 megabytes per second, it's more higher than Bluetoth 2.0 that give us maximum speed transfer at 3 megabytes per second.


Bluetoth 3.0 have a high speed transfer because this wireless technology can be able to penetrate the 802.11 radio protocol that known as WiFi. Although we can combine bluetoth and Wifi, but the transfer of data remain to be done through Wifi on a Wifi network. This especially in the large volume of data transfer, such as images, video, etc.

Blutoth 3.0 also promises a minimum of energy consumption so that it does not absorb much energy, as in previous versions. Supporting this new technology has also been prepared. Atheros and Broadcom, the two companies that make the hardware for this bluetoth are currently preparing for its products. Estimated, in 9 to 12 months, bluetoth 3.0 have enjoyed in the consumer products.

Uff.., it seems we still have to wait this product patiently.

Binary Number, Betwen Math and Computer Science

Binary Number, this is one from many theory of number. Whether it be from math class or computer science class, eventually we will need to learn about number systems, and the mathematics that is involved. But, if we learn about main system of computer, the binary number is involved too. Waht is Binary Number?

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.

Google Docs, an Online and Free Document Operating

May be it's too late for me to post this info. But, in fact just a month ago I find information if there is a free document operating from google, it's named Google Docs. Google Docs was launched by Google as free and online document operating last year. The idea is we can shared our document to our friend. If you want to use it, The Google Document link can be accessed by logging in to the Google Gmail account. Then,
look at the upper left hand side when you are logged in to your Gmail account.

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.

Coming Soon Office 2010

Logo OfficeMicrosoft had announce that Office 2010 will be launched soon. But Microsoft did not want to make sure the date when the product would be lounch. The software maybe will be in the market at the quarter of next year. However, many software reviewer from many media, have got a little information about the excelent fiture of latest version of the software is owned by Bill Gates.

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.
