What are the key features of a low level language?
Answer
Human language, not readable by processor.
Assembly language. Each microprocessor has its own instruction set. Readable by its microprocessor.
Just a series of zeros and ones that are readable by processor.
Presentation of an intended application in the form of diagrams.
Question 2
Question
Explain the features of procedural languages?
Answer
Classes are run at the instance of an object; made up of void methods; makes use of library routines.
Core language of world wide web; defines structure and layout of programming languages.
Made up of 1s & 0s; related to architecture.
Data & code separate; usually modularised; uses the 3 typical constructs (sequence, selection, iteration); programmer specifies order in which instructions are compiled and run.
Question 3
Question
What is object orientated language?
Answer
Uses encapsulations; classes may inherit data and methods from other classes; methods may be defined multiple times in the same class.
Data & code separate; usually modularised; uses the 3 typical constructs (sequence, selection, iteration); programmer specifies order in which instructions are compiled and run.
Uses declarations; shows what properties results should have

Answer
True
False
Question 5
Question
Which of these best describes a class in programming.
Answer
A group of students studying programming.
The level of hierarchy of a programmer based upon their wealth and background.
Describes shared attributes & methods, stating the state & behaviour of a set of objects.
A subroutine that output multiple values after it has been run.
Question 6
Question
Is an object an instance of a class, such as a real world entity or a variable.
Answer
True
False
Question 7
Question
Does a declarative language show how the outcomes of a program are achieved.
Answer
True
False
Question 8
Question
Why is unified modelling language used?
Answer
It is a standard way of presenting information to illustrate the design of a system virtually, so it is easy to understand. It allows systems analysts, programmers & clients to communicate when modifying a system.
Data & code separate; usually modularised; uses the 3 typical constructs (sequence, selection, iteration); programmer specifies order in which instructions are compiled and run.
For neural networks to understand how the mind works.
