Module 2 - Unit 3 - Programming and App Development

Question 1

Software development

Answer 1

A process of creating apps

Question 2

Program

Answer 2

A sequence of instructions for your computer to perform.

Question 3

Compiled programming language

Answer 3

A compiled programming language requires the code to be converted a executable binary before it can run. Compiling converts the source code to machine code.

Question 4

Interpreted programming language

Answer 4

An interpreted language runs within the context of the interpreter, which converts the code into machine code at runtime

Question 5

Query language

Answer 5

This language is specifically written to perform data transaction with a database. It does not need to be compiled. One such example is SQL.

Question 6

Assembly language

Answer 6

Represents machine code in human readable text. An assembly language is typically specific to a particular hardware architecture.

Question 7

Markup language

Answer 7

Not a programming language but a means of making data in a document accessible to a program.

Question 8

Identifier

Answer 8

An identifier is used in a program to access a program element, such as a stored value, class, method, or interface.

Question 9

Variable

Answer 9

A variable contains a value that can change during the execution of the program.

Question 10

Constant

Answer 10

A constant is a specific identifier that contains a value that cannot be changed within a program

Question 11

Container

Answer 11

Container can be used as a term for a special type of identifier that can reference multiple values (or elements)

Question 12

Branches

Answer 12

Branches are instructions to your computer that set and control the flow within a program

Question 13

Loops

Answer 13

Instructs the computer to perform, repeat a task until a condition is met

Question 14

Procedures and Functions

Answer 14

Enables you to create segments of code that you can reuse. The difference between a procedure and a function is that the latter can return a value.

Question 15

Object-Oriented Programming (OOP)

Answer 15

Create code that are recognizable as objects so that they are easier to maintain and update.

Question 16

OOP - Attributes

Answer 16

Values and data types that define the object

Question 17

OOP - Methods

Answer 17

Define what you can do to an object

Question 18

OOP - Properties

Answer 18

Allow external code to ask the object to show or change the value of one of its field.

Question 19

Scripting languages

Answer 19

These are languages that support the automation and configuration of a particular operating system. Examples are Windows Command Prompt, Windows PowerShell or Linux Bash

Question 20

Script

Answer 20

A smaller piece of code than a program. It is generally targeted at completing a specific task, whether that task is based within a web-based application or is used by a network administrator to perform a repetitive administrative task

Question 21

Batch Files

Answer 21

Batch files are a collection of command-line instructions that you store in a .CMD file.

Question 22

Windows PowerShell

Answer 22

A tool to perform management and administrative tasks in Windows.

Question 23

VBScript

Answer 23

A scripting language based on Microsoft’s Visual Basic programming language

Question 24

Single-platform software

Answer 24

This development model is optimized for a particular platform, it can perform better and be simpler to check for errors than cross-platform software.

Question 25

Cross-platform software

Answer 25

This model allows a software to have interoperability between multiple systems, such as desktop and mobile platforms.

Question 26

Web application

Answer 26

Software is run from a web server and can support a wide range of different types of client operating systems and devices.

Question 27

Network server application

Answer 27

These software are installed onto a network server, such that other computer can utilize the software over a local network connection

Question 28

Cloud hosted application

Answer 28

These software are installed onto a cloud computer and other computers can utilize the software over the Internet

Question 29

What shows the structure of code without using the specific syntax of any one language?

Answer 29

Pseudocode

Question 30

what is an interpreted language

Answer 30

interpreted languages do not need to be compiled. They run within the context of an interpreter which converts the code to machine code during runtime.

Question 31

How is markup language differ from a compiled language?

Answer 31

Markup doesn't provide instructions for the CPU to run as such. Markup is a way of using nested tags within a document to describe its structure and contents

Question 32

What are constants and variables examples of?

Answer 32

Programming identifiers

Question 33

What type of programming concept allows for a variable size container?

Answer 33

A vector is a variable size container while an array is a fixed size one.

Question 34

You want to check whether a condition has been met, and if it has, perform one action. Otherwise, you want your program to perform a second action. What sort of programming operation would help achieve this?

Answer 34

A conditional branch, such as an If...Then statement.

Question 35

A loop performs one or more instructions until (or while) a condition is met.

Question 36
