AND / OR / NOT
Deduction is the process of working out if something is TRUE or FALSE.
An AND gate requires both inputs to be switched on.
An OR gate needs just one switch to be on.
A NOT gate will change the input into the opposite.
A repeat structure saves writing so many instructions.
Reducing the amount of data needed to store or transmit something.
The building blocks of the digital circuits.
Decomposition involves breaking down a large problem into smaller sub-problems.
A simplified programming language, used in program design.
To remove unnecessary information in order to solve a problem.
An algorithm is a set of instructions for solving a problem or completing a task.
A mathematical table used to determine if a compound statement is true or false.
Means that some of the original data will be lost.
Means that none of the original data will be lost.
A diagram of the sequence of movements.
2. How computers work
What is a computer?
A computer is a programmable machine.
computer system
All the different parts of a computer, including the devices you plug into it.
Input – Process-Output
Takes in data, processes it and then outputs the result.
What's inside a computer?
Components of a computer: motherboard, CPU, graphics card, RAM, network interface card.
software
The program that we run on our computer system.
