◉ Bit Rate. Answer: The number of bits that can be sent down a wire
per second.
◉ Integer. Answer: A whole number that can be positive, negative or
zero.
Examples: -3, 0, 7, 2013588.
◉ Natural (Number). Answer: A whole number that is either positive
or zero.
Examples: 0, 1, 2, 100, 67238.
◉ Rational (Number). Answer: Any number that can be represented
as the fraction 'a/b' where 'a' and 'b' are both integers.
,Examples: -0.2, 4/5, 1, 1/3.
◉ Irrational (Number). Answer: Any number that cannot be
represented as a fraction.
Examples: square root of 2, PI.
◉ Real (Number). Answer: Any number that can either be rational
or irrational.
◉ Boolean. Answer: A value that is either true or false.
◉ String. Answer: A series of characters.
◉ Array. Answer: A variable that can store multiple values of the
same data type.
Example: Storing the high-scores of a game as integers.
◉ Record. Answer: A variable that can store multiple values that can
have different data types.
,Example: Storing data about a book; a string for the title, an integer
for the number of pages, etc.
◉ Variable. Answer: A metaphor for it is that is a box that can store a
specific type of item (the data type) and has a name assigned to it
(the identifier). Its value can be changed during run-time of the
program.
◉ Constant. Answer: A metaphor for it is that is a box that can store
a specific type of item (the data type) and has a name assigned to it
(the identifier). Its value cannot be changed during run-time of the
program.
◉ Subroutine. Answer: This can be broken down into procedures
and functions.
◉ Procedure. Answer: A block of code that performs a specific task
that does not return a value. Parameters can be passed into it.
◉ Function. Answer: A block of code that performs a specific task
that returns a value. Parameters can be passed into it.
◉ Selection. Answer: This is when an if statement or select case is
used to, for example, check the value of a variable.
, ◉ Iteration. Answer: This is when, within the program, there is a
loop.
◉ Definite Iteration. Answer: The number of times that the program
will loop is already specified.
Example: For loop.
◉ Indefinite Iteration. Answer: The number of times the program
will loop is unknown.
Example: Do loop.
◉ Nested (structures). Answer: This is when either iterative or
selective statements are put inside of each other.
◉ Meaningful Identifiers. Answer: Subroutines, variables and
objects should have sensible names.
◉ Real Division. Answer: Finds the value (usually as a decimal) of
one number divided by another.
◉ Integer Division. Answer: Finds the integer part of one number
divided by another.
