19 Conclusion

In sections 15–18, we examined the components and processes of an ICT system that is used for an everyday activity: shopping. We started by looking at a system map of the 'checkout system' before exploring the processes involved at the checkout. We considered some examples of networks and discussed the processes involved in a networked supermarket ICT system. Finally, we looked briefly at another way in which ICT systems can be used for shopping: e-commerce.
