INMT 442 Exam 1 Questions and Answers Abstraction process of representing the most important parts of something without including complex background information User expirence the feelings and attitudes a person has when they are using a product User persona a made-up profile for a person who matches the characteristics of someone who might use a particular product Pattern recognition finding a pattern in a set of data Algorithm a list of step by step instructions for how to complete a task Imperative approach explicit programming- focusing on how the problem should be solved and requires detailed, step by step instructions for solving a problem Declarative approach also called model based programming- implicit programming focuses on what to execute, defines program logic but does not detail control flow Key elements of debugging design (declaring what the product should look like), build (creating a version of the product), test (getting feedback on the product from other people) Debugging identifying and removing errors Prototype early version of a product Software development lifecycle 1) define the problem 2) analyze the problem 3) develop algorithm 4) code & document 5) test & bug 6) maintain Traditional (data + algorithm) you hard code the behavior of the application, creates a suitable algorithm, then write the code, programmer sets mandatory parameters, and a valid programmed algorithm will produce expected results Machine learning (math/stats + algorithms) subset of AI, ML denotes systems that can learn from experience, computers can learn without implicit directions A program/application/app can be decomposed into algorithms + data Object oriented program blurs the lines for solving a problem, based on conducting a series of specified actions Algorithm (is often) logic + controlled logical deduction Algorithms include three features Sequences, Decisions, Repetition Sequence also known as process- completed 0 or 1 time Decision (also known as selection)- performed 0 or 1 time Repetition (also known as iteration or looping)- depending on logic, performed 0 to many or 1 to many times Process or sequence a step in the algorithm executed in a specified order Decision block of code ex. if... then, if... then... else Repetition block of code ex. Do while/until... loop GUI graphical user interface is a program that takes advantage of computers graphic capaabilities Events actions that are triggered by: the user, other objects, the operating system Event handlers a block of code written to generate outcome or action based on specified event Where can you store values during app processing? variables, arrays, object properties, lists, dictionaries, sets, and tuples Variable a container for a single data value ex. dim variablename or variablename= value Arrays data structures that allow you to store and work with multiple values of the same data type, you can create different types of arrays (numeric, character, string) Object programming constructs that have data, behavior and identity Object data values contained in various object properties 4 object classes application object, workbooks object, worksheet object, range object Property an attribute to which you assign a value ex. A flowers attributes might include name, color, size ex. Ortyname ex. T To assign a value to a property use = ex. Ortyname = "hello" Method an action that an object "knows" how to perform (because the application programmer has provided the method instructions) VB use the following notation dname() Class a template or set of specifications used to create objects you want to include in your application, in VB you place the class specifications inside a class module ex. The cookie cutter is the class because it defines the characteristics of each cookie (object) (shape & size).
