Parts of a computer
A computer has input devices to put information in, a processor to work on it, memory and storage to keep it, and output devices to show results. Software tells it what to do.

Algorithm
An algorithm is a precise, step-by-step set of instructions for solving a problem or doing a task. Computers follow algorithms written as code.
Online safety
Staying safe online means keeping personal details private, using privacy settings and strong passwords, being kind, and telling a trusted adult if anything worries you.
Coding
Coding, or programming, means writing instructions in a language a computer understands so it can do a job, like run a game, an app or a website.
Debugging
Debugging means finding and fixing mistakes, called bugs, in an algorithm or a computer program. It is a normal part of coding for everyone.
