A variable is a named memory location that can store a number or any other type of data
that changes over the duration of the program’s run. A variable can be assigned a value,
modified, or used in calculations or operations. A variable is different from a constant,
which is a fixed value that does not change. A variable is also different from a loop, which
is a control structure that repeats a block of code until a condition is met. A variable is also
different from a function, which is a named block of code that performs a specific task and
can be reused12.

Binary is a notational system used to represent an “on” or “off” state in digital devices or systems.
Binary uses only two symbols: 0 (off) and 1 (on). Binary is also known as base 2 notation, because
each symbol represents a power of 2. Binary is the fundamental building block of all computer
operations and data storage, as it can encode any type of information using sequences of bits (binary
digits)1112.
