Computer Science: KS3, topic 2.2.1
Code
When you have an algorithm for a computer task, we need to turn it into a computer language so the computer can understand how to follow the steps in the algorithm.
Computer languages
- There are many computer languages for creating programs.
- A program is a set of instructions to carry out a task.
Machine code
- At the lowest level, the computer uses machine code.
- Machine code is based on the numbers 0 and 1.
- The machine code system is called ‘binary’ because there are only two numerals you can use.
Higher-level languages
- BASIC, C, Java, and HTML are all names of higher-level computer languages.
- Each of the languages uses different codes.
- Each language is different just like Spanish is different from English.
