NOTE:

CONVERT DECIMAL NUMBERS TO BINARY

For Example...

Recap.. :)

Let us answer some questions if you have already know something ..

Madali lang to Promise! :)

Convert 25 to binary

Quotient Remainder

25/2 12 1

12/2 6 0

6/2 3 0

3/2 1 1

1/2 0 1

25 = 11001

To convert a decimal number to binary, all you have to do is divide the number by 2.

Get the quotient and the remainder.

Bring down the quotient, divide it by 2, and get the quotient and remainder again.

Do it repeatedly until the quotient results to 0.

Copy the remainder from bottom to top, and that is the binary equivalent.

Each group of

eight bits

, such as the representations of letters and numbers, is known as a

byte.

Codes can be used to represent almost any type of information digitally: computer

data, graphics, photos, voice, video , and music

Computers use

binary codes

to represent and interpret letters, numbers and special

characters with bits.

A commonly used code is the

American Standard Code for Information Interchange.

Digital Representation

Within a computer, information is represented and stored in a

digital binary format

.

The term

bit

is an

abbreviation

of

binary digit

and represents the smallest piece of data.

A bit can have only two possible values,

a one digit (1)

or a

zero digit (0)

.

A bit can be used to represent the state of something that has two states.

For example, a

light switch

can be either

On or Off

; in binary representation, these states would correspond to 1 and 0, respectively.

BIT

With ASCII, each character is represented by a

string of bits.

For example:

Capital letter: A = 0100 0001

Number: 9 = 0000 1001

Special character: # = 0010 0011

ASCII

Checking:

25 = 11001

1 1 0 0 1 multiplier

16 8 4 2 1 equivalents

16 8 0 0 1 results

16+8+1 = 25

Let's check
