Baud Rate>>> The maximum possible number of signal changes that can occur in a wire per second. Bit Rate>>> The number of bits that can be sent down a wire per second. Integer>>> A whole number that can be positive, negative or zero. Examples: -3, 0, 7, 2013588. Natural (Number)>>> A whole number that is either positive or zero. Examples: 0, 1, 2, 100, 67238. Rational (Number)>>> 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)>>> Any number that cannot be represented as a fraction. Examples: square root of 2, PI. Real (Number)>>> Any number that can either be rational or irrational. Boolean>>> A value that is either true or false. String>>> A series of characters. Array>>> A variable that can store multiple values of the same data type. Example: Storing the high-scores of a game as integers. Record>>> 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>>> 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>>> 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>>> This can be broken down into procedures and functions. Procedure>>> A block of code that performs a specific task that does not return a value. Parameters can be passed into it. Function>>> A block of code that performs a specific task that returns a value. Parameters can be passed into it. Selection>>> This is when an if statement or select case is used to, for example, check the value of a variable. Iteration>>> This is when, within the program, there is a loop. Definite Iteration>>> The number of times that the program will loop is already specified. Example: For loop. Indefinite Iteration>>> The number of times the program will loop is unknown. Example: Do loop. Nested (structures)>>> This is when either iterative or selective statements are put inside of each other. Meaningful Identifiers>>> Subroutines, variables and objects should have sensible names. Real Division>>> Finds the value (usually as a decimal) of one number divided by another. Integer Division>>> Finds the integer part of one number divided by another. Integer Remainder>>> Finds the remainder of one number divided by another. Truncation>>> Chops the decimal part off a number. Floor>>> Rounds a number down to the nearest integer. Ceiling>>> Rounds a number up to the nearest integer. AND>>> Logical Operation: Returns true only when both values are true. OR>>> Logical Operation: Returns true as long as at least one of the values are true. XOR>>> Logical Operation: Returns true only when exactly one of the two values is true and not both. NOT>>> Logical Operation: Returns true if the value is false and returns false if the value is true. Exception Handling>>> When a try catch is used in the program to deal with any errors that may occur. ByVal>>> When a variable is passed into a subroutine as a copy so its value will not be changed. ByRef>>> When a variable is passed into a subroutine as a reference so its value can be changed. Local (Variable)>>> A variable that is defined, for example, within a subroutine and cannot be viewed or modified from outside of the block of code is was declared in. Global (Variable)>>> A variable that is declared, usually at the start of the program, and can be accessed and modified from anywhere at all in the program. Recursion>>> A subroutine's definition contains a self-call meaning a function or procedure calls itself as a way of performing iteration. Object-Oriented (Programming)>>> A type of programming paradigm when multiple objects are created and handled to run the program. Example: In a game you might have an object for the player and then multiple objects for the enemies. Procedural (Programming)>>> A type of programming paradigm when you break down a project, usually using a decomposition diagram, into individual tasks which can each be performed by a procedure. Functional (Programming)>>> A type of programming paradigm that is mainly used for calculations. No variables are declared, only functions are used with parameters and return statements. (Object) Instantiation>>> When an object is first created using the 'new' keyword.
