Binary Representation of Information
Binary code is the most basic form of data that a computer can directly interpret. Computers
use binary code, composed of 1s and 0s, to store and process data. These 1s and 0s represent
electrical signals: ON for 1 and OFF for 0. For instance, the number 5 is stored as 0101 in binary.
Binary numbers can also represent text characters through the American Standard Code for
Information Interchange (ASCII). For example, the binary code for the ASCII uppercase letter ‘A’
is 1000001.
Clickipedia
ASCII is made up of 128 symbols in the character set. These symbols consist of letters (both
uppercase and lowercase), numbers, punctuation marks, special characters and control
characters.

1 0001 6 0110
2 0010 7 0111
3 0011 8 1000
4 0100 9 1001
5 0101 10 1010
CONDITIONS IN A PROGRAM
While writing a program, we need to make certain decisions based on the logic of the program.
Such situations are called conditions. Conditional statements are used in a program to instruct
the computer to make a decision. The result of a condition will always be either True or False.
if-then-else
The program executes the statements written inside the Start
IF block when the condition is True. If the condition is
False, the statements written inside the else block will be
executed. A block refers to a section
IF (Condition)
of code that is grouped together. True to be checked False
Statements inside IF Statements inside ELSE
block will execute block will execute
