Computer Science - Paper 1 Abstraction and Auotmation

Logical Reasoning

Using a given set of facts to determine whether new facts are true or false 

Problem Solving

Finding solutions to real-life problems

Algorithm

A sequence of instructions for carrying out a particular task

Representational Abstraction

Removing unnecessary details so that only information that is required to solve the problem remains

Abstraction by Generalisation/Categorisation

The process of placing similar aspects of a problem in into broader categories and representing them hierarchically

Procedural Abstraction

Breaking down a complex problem into a series of procedures and subroutines

Functional Abstraction

Breaking down a complex problem into a series of reusable functions 

Data Abstraction

Hiding how data is represented so that it is easier to build a new kind of data object

Problem Abstraction

Removing unnecessary details from a problem until the underlying problem is identified to see if it is similar to a problem that has already been solved

Information Hiding

The process of hiding all the details of an object that do not contribute do its essential characteristics/ providing the definition or interface of a system or object whilst keeping the inner works hidden

Decomposition

Breaking down a large task into smaller, more manageable tasks

Procedural Decomposition

Breaking down a system into smaller procedures and subroutines

Composition

Building up a whole system from smaller units

Procedural Composition

Creating a working system from abstraction

Automation

The process of creating a computer model of real-life situations and putting them into action
