What do computers store or save things onto?

What is the difference between software and hardware?
Software is a set of instructions that tell the computer what to do. All computer games and apps are software.
Hardware is the physical parts of a computer like the screen, keyboard, mouse, speakers, storage drive.
We save things we want to keep as files. How and why do we keep our files organised?
saved game positions, documents, photos, videos
We give them sensible names that tells us what is in the files. If we do not give them sensible names, we won’t know which file to retrieve (open) when we need it.
What do Word Processors do?
Let us create written documents. In documents you can add photos or other images.

All the shops items for sale and their details (such as price and barcode) are stored in the database. When someone scans the barcode and pays for their items, the stock level and reordering can be carried out automatically.
Similar things happen in online stores and libraries when you borrow books.
You can use the internet on laptops, tablets, phones, watches etc
