1
Q
What are the computational models that every computer program follow ?
A
input — process — output
2
Q
What is input?
A
- to enter data into a computer.
3
Q
What is process?
A
- process is to change the meaning or format of some data.
4
Q
What is output?
A
- output is to display or output data that has been processed (or has been stored)
5
Q

A
- a metaphor or diagram that represents a machine that takes an input.
6
Q
What are the 3 types of computational models
A
- sequential.
- parallel.
- multi- agent.
7
Q
What is a sequential computational model?
A
- this involves following instructions in an algorithm step by step, in order, from start to finish.
8
Q
What is parallel computational model?
A
- A parallel model is one task where the computer processes are distributed between two or more processors in a computer with two or more processors.
9
Q
What is a multi-agent computational model?
A
where separate tasks or algorithms are processed by different systems to per
10
Q
What is an agent?
A
- a computer system that can interpret its environment. (through its sensors). It can act autonomously upon that environment.
11
Q
What is autonomous?
A
self directed and acts without requiring any help or guidance.
12
Q
What is an effector?
A
Something that produces an effect by carrying out an action.
