The document focuses on digital representation, particularly the conversion of decimal numbers to binary format and the roles of bits in computing. It explains the method to convert decimal to binary through division and outlines the ASCII code for representing characters. Additionally, it includes activities to reinforce understanding of binary numbers and data storage concepts.

3. At the end of the lesson, the learners are
expected to:
1.Demonstrate how to compute to get
the binary digits
2.Convert Decimal Numbers to Binary
Numbers
3.Apply method in checking the
conversion from Decimal to Binary

5. 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

6. 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

7. •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.
•Capital letter: A = 01000001
•Number: 9 = 00001001

8. 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.

9. CONVERT DECIMAL NUMBERS TO BINARY
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.
