3. 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.
Humans interpret words and pictures;
computers interpret only patterns of bits.
4. 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.
5. 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 (ASCII).
With ASCII, each character is represented by a string
of bits.
Codes can be used to represent almost any type of
information digitally: computer data, graphics,
photos, voice, video , and music.
6. The word binary comes from "Bi-" meaning
two. We see "bi-" in words such as "bicycle"
(two wheels) or "binocular" (two eyes).
binary number is a number expressed in
the binary numeral system, or base-2
numeral system
7. To show that a number is a binary number
follow it with a little 2 like this: 1012
This way people won't think it is the decimal
number "101" (one hundred and one).
8. Character Bin Dec
• (ASCII)
Capital letter: A 1000001₂ (65)
Number: 9 111001 ₂ (57)
Special character: # 100011 ₂ (35)
9. 1.To convert decimal whole numbers from base 10 to any
other base, divide that number repeatedly by the value of
the base to which the number is being converted.
2.The division operation is repeated until the quotient is 1.
3.The sequence of remainders from bottom up to yields
the required binary equivalent.
