What a network provides
A network links devices so they can share data, hardware (like a printer) and internet access. The internet itself is a huge network of networks, connecting billions of devices using agreed rules called protocols.

Collaboration tools
Cloud storage lets multiple people edit the same document simultaneously, with changes syncing instantly; video calls let teams meet without travelling; shared calendars coordinate schedules across time zones.

Trade-offs to consider
Networked collaboration is fast and flexible, but relies on a stable connection, raises questions about who owns shared data, and needs care over access permissions so only the right people can view or edit files.

Your written work for this lesson
This is the part you'd do in your book at school. Pick the pieces below, write here or on paper, and photograph anything you draw or work out.
How a supermarket checkout knows the price
When a barcode is scanned, the checkout does not store the price itself. It sends the barcode number to a database and reads back a record: product name, price, whether it needs an age check. The record is the single place the price lives, so changing one row changes every till in the shop at once.
Problems come from bad data, not bad scanners. If two products share a barcode, or a price update reaches the shop overnight but the till holds an old copy in its cache, customers are charged the wrong amount. Shops check this with test transactions: scan a known item, expect a known price, record what actually happened.
Good systems also log every scan. If a customer complains, the log shows exactly which record was used and when.
Written for Good Learning Co.
Reading questions
- Write in your own words what the checkout sends and what it receives back.
- Explain one way bad data could cause a wrong price, and how logging helps find it.
- Design a test table with four tests for a new checkout, with expected and actual results.
