indicates how various senders and receivers handle blocks of data in a particular communication protocol.

testing (program/software)

Finding out how well something works.

variable

is a storage location (identified by a memory address) paried with an associated symbolic name, which contains some known or unknown quantity of information referred to as a value.

Variable naming (self-identify, camelCase, etc)

Variable naming (self-identify, camelCase, etc)

assignment operator

assigns the value of its right-hand operand to a variable, a property, or an indexer element given by its left-hand operand.

algorithm

is a set of instructions designed to perform a specific task.

programming languages

languages used to create applications and, in multimedia, to produce sophisticated features such as creating animations and searching databases

algorithm construction

Every algorithm can be constructed using combinations of sequencing, selection, and iteration

software development process

A process of planning and managing software development.

software development process phases

planning, analysis, design, build, test, implement, and maintenance/support.

iterative development

a way of breaking down the software development lifecycle (SDLC) of a large application into smaller chunks.

incremental development

any combination of both iterative design or iterative method and incremental build model for development.

software design process

A way to improve design and product management by breaking software development work into smaller steps or sub-processes that can be done in parallel or in-order.

sequencing; sequential statements

The specific order in which instructions are performed in an algorithm.

code statement

a syntactic unit of an imperative programming language that expresses some action to be carried out.

expression

syntactic entity in a programming language that may be evaluated to determine its value. It is a combination of one or more constants, variables, functions, and operators that the programming language interprets and computes to produce another value.

the process of appending one string to the end of another string.

substring

a contiguous sequence of characters within a string.

points where a decision must be made. implemented in programming using IF statements.

Uses Boolean expressions in the form of logical if/else and then statements to evaluate if something is true or false.

nested conditional statements

conditional statements within conditional statements

iteration

A function that repeats a block of code in a specified order, often until a specific result occurs

procedure (method, function)

a function returns a value, but a procedure does not. a method is similar to a function, but is internal to part of a class

a way for you to provide more information to a function

procedure call

a simple statement made by stating the procedure name, listing actual parameter names or values within parentheses, and adding a final semicolon

procedure abstraction

the process of breaking down a complex problem into smaller, more manageable steps.

modularity

a software design technique that emphasizes separating the functionality of a program into independent, interchangeable modules, such that each contains everything necessary to execute only one aspect of the desired functionality
