Development/ Progamming

Question 1

Machine Language

Answer 1

Machine Language is also known as Machine code, and are instruction sets performed by a computer’s CPU.

Question 2

Assembly Language

Answer 2

Refers to higher level code used by programmers to
‘assemble’ machine language. Essentially, phrases and commands written in assembly language correspond to (usually much longer) commands in machine language.

Question 3

Unit Testing

Answer 3

Is the testing od individual units or modules of code in a program,, to ensure that they work before they are placed into a larger routine or programming.

This allows problems to be found early in development, as each piece of code is developed.

Question 4

Object-oriented programming

Answer 4

Uses objects which represent data tables, and procedures which manipulate objects known as “methods’.

Example:

Java and C# are both object oriented languages.

Question 5

Procedural Programming

Answer 5

Takes a program through a sequential set of instructions, with future commands based off of based obtained from previous commands.

Question 6

FORTRAN

Answer 6

Derived from the IMB Mathematical Formula Translating System is a programming language developed in the 1950’s.

Question 7

Pascal

Answer 7

A procedural programming language developed in 1970.

Question 8

BASIC

Answer 8

Short for Beginner’s All-purpose Symbolic Instruction Code was developed in 1964 and is a high level programming code targeted for beginning learners.

Question 9

C -

Answer 9

Developed in 1972 by AT&T/ Bell Labs and is one of the most commonly used programming languages.

Question 10

C + +

Answer 10

Mid/high level programming language derived from the original C language released in 1983.

Question 11

C #

Answer 11

Spoken as “C Sharp”, this is a multi-paradigm (both procedural and object-oriented) programming language that is in use today.

Question 12

Java

Answer 12

An object-oriented programming language developed in 1995.

Question 13

Variable

Answer 13

Symbolic name is then assigned a value for future use by a program.

Example:

$Var = “Justin” is the variable $Var with the value of “Justin”

Question 14

String

Answer 14

A string is a type of variable that contains “strings” of characters.

Question 15

Module

Answer 15

Independent ‘section’ of code, designed for one specific purpose

Modular programming tries to break each task down into its own “module” so that it can be picked up and used in other programs with little change or effort.

Question 16

Function

Answer 16

A function is a set of instructions for a task. It is usually pre-defined in a separate set of code, which it can be “called” for use in a larger program.

Question 17

Class

Answer 17

A class, in object oriented programming, is a definition of an object. It contains a data table/ field for the class properties.

Question 18

Method

Answer 18

A programming subroutine associated with a class that defines the operation performed by the class in an instance.

Question 19

Algorithm

Answer 19

An algorithm is a process for performing a calculation that produces an output from an input using a given set of rules.

Question 20

Array

Answer 20

An array is an arrangement of value objects, in the form of a table with rows and columns. You can think of them as lists of objects.

Question 21

Loop

Answer 21

A set of instructions which is repeated until a specified condition is reached.

Question 22

Complier

Answer 22

Transforms higher level programming code into machine code.

Question 23

Interpreter

Answer 23

Used to execute instructions written in a high level programming language.

Question 24

Debugging

Answer 24

Is the process of removing errors in a program code.
