DATA ORGANIZATION
PRE-READING ACTIVITY
Answer the following questions orally:
1. What is data organization?
2. Do computers work with a specific code?
3. Are there different code types?
BITS
Read the text that appears on the link’s section
and answer T or F.
 There is not a wide variety of items people can
represent with a bit
 People can represent finite binary data types
 Bits always represent the same.
 Bits are not so important in programs.

SYSTEMATIZATION
EXAMPLES
• However, you can represent only two different values with a
single bit.
• However, since everything else consists of groups of bits, bits will
play an important role in your programs.
• However, you will soon see that individual bits are difficult to
manipulate, so we'll often use other data types to represent boolean
values.
NOTION: contrast
RULE: However, …
….., however, …
ACTIVITY 1
Create new sentences in a Word document using “however” with the
information provided below. Then, upload the archive to the “LESSON
1” page on the wiki with your surname as the name of the archive.
1. In pure mathematics a value may take an arbitrary number of bits.
Computers generally work with some specific number of bits.
2. You may get the impression that there are a very small number of items
you can represent with a single bit but there are an infinite number of
items you can represent with a single bit.
3. In information theory, "one bit" is typically defined as the uncertainty
of a binary random variable that is 0 or 1 with equal probability, whereas
in quantum computing, a quantum bit is a quantum system that can exist
in superposition of two bit values, "true" and "false".
4. A bit is usually represented by an electrical voltage or current pulse.
But it can also be represented by the electrical state of a flip-flop circuit.
