Year8 Computer Science

Computers use binary to process data. There are simple techniques to convert between binary and denary and to add two binary numbers together.

When designing programs, there may be some instructions that need repeating. This is known as iteration, and is implemented in programming using FOR and WHILE statements.

When designing programs, there are often points where a decision must be made. This decision is known as selection, and is implemented in programming using IF statements.

When designing algorithms, there may be some steps that need repeating. This is known as iteration, and can be displayed in pseudocode or flowcharts.

When designing algorithms, there are many steps where decisions must be made. This decision is known as selection, and can be displayed in pseudocode or flowcharts.

When designing algorithms, it is important to make sure that all the steps are presented in the correct order. This is known as sequencing, and can be displayed in pseudocode or flowcharts.
